Differentiation of bloodstream-form trypanosomes into procyclic (midgut) forms is an important first step in the establishment of an infection within the tsetse fly. This complex process is mediated by a wide variety of factors, including those associated with the vector itself, the trypanosomes and the bloodmeal. As part of an on-going project in our laboratory, we recently isolated and characterized a bloodmeal-induced molecule with both lectin and trypsin activities from midguts of the tsetse fly, Glossina longipennis [Osir, E.O., Abubakar, L., Imbuga, M.O., 1995. Purification and characterization of a midgut lectin-trypsin complex from the tsetse fly, Glossina longipennis. Parasitol. Res. 81, 276-281]. The protein (lectin-trypsin complex) was found to be capable of stimulating differentiation of bloodstream trypanosomes in vitro. Using polyclonal antibodies to the complex, we screened a G. fuscipes fuscipes cDNA midgut expression library and identified a putative proteolytic lectin gene. The cDNA encodes a putative mature polypeptide with 274 amino acids (designated Glossina proteolytic lectin, Gpl). The deduced amino acid sequence includes a hydrophobic signal peptide and a highly conserved N-terminal sequence motif. The typical features of serine protease trypsin family of proteins found in the sequence include the His/Asp/Ser active site triad with the conserved residues surrounding it, three pairs of cysteine residues for disulfide bridges and an aspartate residue at the specificity pocket. Expression of the gene in a bacterial expression system yielded a protein (M(r) approximately 32,500). The recombinant protein (Gpl) bound d(+) glucosamine and agglutinated bloodstream-form trypanosomes and rabbit red blood cells. In addition, the protein was found to be capable of inducing transformation of bloodstream-form trypanosomes into procyclic forms in vitro. Antibodies raised against the recombinant protein showed cross-reactivity with the alpha subunit of the lectin-trypsin complex. These results support our earlier hypothesis that this molecule is involved in the establishment of trypanosome infections in tsetse flies.
Huberman AD, Feller MB, Chapman B. "Mechanisms {Underlying} {Development} of {Visual} {Maps} and {Receptive} {Fields}." Annual Review of Neuroscience. 2008;31:479-509. AbstractWebsite

Patterns of synaptic connections in the visual system are remarkably precise. These connections dictate the receptive field properties of individual visual neurons and ultimately determine the quality of visual perception. Spontaneous neural activity is necessary for the development of various receptive field properties and visual feature maps. In recent years, attention has shifted to understanding the mechanisms by which spontaneous activity in the developing retina, lateral geniculate nucleus, and visual cortex instruct the axonal and dendritic refinements that give rise to orderly connections in the visual system. Axon guidance cues and a growing list of other molecules, including immune system factors, have also recently been implicated in visual circuit wiring. A major goal now is to determine how these molecules cooperate with spontaneous and visually evoked activity to give rise to the circuits underlying precise receptive field tuning and orderly visual maps.

Huberman AD. "Mechanisms of eye-specific visual circuit development." Current opinion in neurobiology. 2007;17:73-80. Abstract

Eye-specific visual connections are a prominent model system for exploring how precise circuits develop in the CNS and, in particular, for addressing the role of neural activity in synapse elimination and axon refinement. Recent experiments have identified the features of spontaneous retinal activity that mediate eye-specific retinogeniculate segregation, the synaptic events associated with this process, and the importance of axon guidance cues for organizing the overall layout of eye-specific maps. The classic model of ocular dominance column development, in which spontaneous retinal activity plays a crucial role, has also gained new support. Although many outstanding questions remain, the mechanisms that instruct eye-specific circuit development are becoming clear.

Fifteen yearling goats with similar weight were used to evaluate the potential of Zizyphus spina-christi leaves as a supplement to goats fed on Cynodon dactylon grass. Animals were randomly assigned to five feeding regimes and individually stall-fed for a preliminary period of 14 days, followed by 14 days of feeding to determine dry matter intake and digestibility, and a 3-month  feeding period to determine body weight changes. The treatments were formulated based on leaf: grass ratios of 0%, 25%, 50%, 75%, and 100%. Z. spina-christi leaves had higher crude protein and lower fibre content than C. dactylon grass (P<0.05). Dry matter intake, digestibility and body weight changes increased significantly (P < 0.05) as the level of supplementation increased. Thus, Z. spina-christi foliage is a potential feed supplement in the dry season, as the dry season grasses are deficient in the required nutrients and cannot meet goat requirements

To evolve a simple oxygen electrode-based method to estimate alternative respiration, one needs to develop a procedure to prevent switch-over of electrons to either pathway upon inhibition by cyanide or salicylhydroxamic acid. It was hypothesized that the inclusion of appropriate electron acceptor, possessing redox potential close to one of the electron transport carriers in between ubiquinone (branch point) and cytochrome a-a3, should be able to stop switch-over of electrons to either pathway by working as an electron sink. To test the hypothesis, 2,6-dichloro-phenol indophenol (DCPIP; redox potential +0.217 V), an artificial electron acceptor having a redox potential quite similar to the site near cytochrome c1 (redox potential +0.22 V) on the cyanide-sensitive pathway, was used with isolated mitochondria and leaf discs in the absence and presence of inhibitors (potassium cyanide, antimycin A, and salicylhydroxamic acid). Polarographic data confirmed electron acceptance by DCPIP only from the inhibited (by cyanide or salicylhydroxamic acid) mitochondrial electron transport chain, hence preventing switch-over of electrons between the cyanide-sensitive and cyanide-insensitive pathway of respiration. Results with antimycin A and reduction status of DCPIP further confirmed electron acceptance by DCPIP from the mitochondrial electron transport chain. Possible implications of the results have been discussed. Copyright 1999 Academic Press.

Brown PM, Tompkins CV, Juul S, Sönksen PH. "Mechanism of action of insulin in diabetic patients: a dose-related effect on glucose production and utilisation." British Medical Journal. 1978;1:1239-1242. Abstract

Six insulin-requiring diabetics were studied after insulin had been withheld for 24 hours. On three separate occasions each received a two-hour infusion of insulin at a low dose (2.6 U/h) and a high dose (10.6 U/h) and an infusion of saline as control. The rates of production and utilisation of glucose were measured isotopically. The rate of fall of plasma glucose concentration was faster on the high-dose infusion of insulin than on the low, whereas the fall in plasma free fatty acids, glycerol, and keton bodies was the same on both insulin infusions. The mechanism whereby the two rates of insulin administration lowered plasma glucose concentration differed: during the low-dose infusion the decrease in the glucose concentration was produced entirely by a fall of hepatic glucose output, whereas during the high-dose insulin infusion the glucose concentration fell because both the rate of glucose production fell and the rate of glucose utilisation rose. In all experiments there was a direct relation between a fall in serum potassium concentration and the fall in plasma glucose concentration irrespective of the mechanism that reduced the glucose concentration.These results indicate that in uncontrolled diabetics low-dose insulin infusions lower the blood glucose concentration entirely by reducing glucose production from the liver and that the effect of insulin on potassium transport is independent of its effect on glucose uptake.

Ostriches have been filmed running fast in their natural habitat. A female ostrich has been dissected and the principal bones, muscles and tendons in a leg have been measured. It is calculated that stresses up to 240 kN m−2 and 40 MN m−2, respectively, act in the digital flexor muscles and their tendons during running. Tensile and compressive stresses up to about 70MNm−2 and 110 MNm−2 act in the tibiotarsus. A large proportion of the energy which would otherwise be required for running is probably saved by elastic storage in tendons. Comparisons are made with the legs of flying birds and of antelopes

A cross sectional study of 115 patients admitted at the Department of Orthopedics, Kenyatta National Hospital, Nairobi, Kenya was carried out to determine the prevalence and antibiotic susceptibility of Staphylococcus aureus isolated from infected wounds. The prevalence of Staphylococcus aureus was 33.0 %. The drugs tested and their corresponding sensitivity was amoxycillin (13.2 %), co-amoxyclav (39.5 %), oxacillin (55.3 %), erythromycin (44.7 %), gentamicin (60.5 %), ciprofloxacin (62.2 %), minocycline (86.8 %), cefuroxime (57.9 %), and clidamycin (84.2 %). These results show the sensitivity profile of Staphylococcus aureus and can be used to choose suitable drugs in the management of wounds for hospitalized patients.

Background & objectives: Bancroftian filariasis in Kenya is endemic in coastal districts with anestimated number of 2.5 million people at risk of infection. The main mosquito genera involved intransmission of Wuchereria bancrofti in these areas are Anopheles, Culex and Mansonia. Thestudy was envisaged to compare the infectivity rates of Bancroftian filariasis vectors between thehigh transmission (wet) and the low transmission (dry) seasons.Methods: Mosquitoes were sampled from houses and compounds from two study sites, Gazi andMadunguni, on the Kenyan coast. Day resting indoor collection (DRI), pyrethrum spray catch(PSC) and CDC light traps were used to collect mosquitoes. After identification, female mosquitoeswere dissected to search for W. bancrofti III stage larvae.Results: A total of 1832 female mosquitoes were dissected. Infectivity rates of vectors in Madunguniwere 1.49 and 0.21% in wet and dry seasons respectively, whereas in Gazi, these were 1.69 and0%, respectively. There was a significant difference in the infectivity rates between the two seasonsin both Madunguni and Gazi villages (p <0.05). Anopheles gambiae s.l. was the main vector inboth study sites followed by Culex quinquefasciatus and An. funestus.Conclusion: There was a difference in infectivity rates of Bancroftian filariasis vectors betweenthe wet and dry seasons. The abundance of An. gambiae s.s. during the transmission season couldbe responsible for the increased infectivity rates of vectors in this season.

Five plaster of Paris casting bandages including Nairobi Enterprises, Salvagyps, Helm, Plasrum-gyps and Veronese, available on the Kenyan market were evaluated based on breaking strength. Helm plaster of Paris had a significantly higher mean maximum load compared to all the other products (p-0.050. Plasrun-gyps supported the highest mean maximum load per unit thickness. Based on this study, Helm and Plasrun-gyps are recommended as more suitable for cast application on the basis of their superior breaking strength.

Variations among silk of four African wild silkmoths, Argema mimosae, Anaphe panda, Gonometa postica, and Epiphora bauhiniae, was studied regarding their mechanical properties and thermal degradation behaviors. Cocoon shells and individual degummed fibers were examined using tensile testing, thermogravimetric analysis, and scanning electron microscope (SEM). A. mimosae and G. postica cocoon shells had marginally higher initial moduli and strains at maximum stress. The stress–strain curves of Bobmyx mori and A. panda degummed fibers lacked clear yielding points. G. postica fibers had the highest breaking energy (76.4 J/cm3) and breaking strain (41.3%). The ultimate tensile strength was the highest for B. mori (427 MPa). Fiber pull-out and detachment was predominant in fracture surfaces of both the cocoon shells and the fibers. Wild cocoon shells and degummed fibers had higher temperature for dehydration loss than B. mori. A. mimosae fibers (11.9%) and G. postica cocoon shells (13.3 %) had the highest weight loss due to dehydration. E. bauhinae cocoon shells and B. mori fibers had the highest total weight losses of 97.2 and 93.4%, respectively. The African silks exhibited variations in their mechanical and thermal degradation properties related to their physical and chemical structure and composition. © 2012 Wiley Periodicals, Inc. J. Appl.

The present study examines the effect of animal-source-food (ASF) intake on arm muscle area growth as part of a larger study examining causal links between ASF intake, growth rate, physical activity, cognitive function and micronutrient status in Kenyan schoolchildren. This randomised, controlled feeding intervention study was designed with three isoenergetic feeding interventions of meat, milk, and plain traditional vegetable stew (githeri), and a control group receiving no snack. A total of twelve elementary schools were randomly assigned to interventions, with three schools per group, and two cohorts of 518 and 392 schoolchildren were enrolled 1 year apart. Children in each cohort were given feedings at school and studied for three school terms per year over 2 years, a total of 9 months per year: cohort I from 1998 to 2000 and cohort II from 1999 to 2001. Food intake was assessed by 24 h recall every 1-2 months and biochemical analysis for micronutrient status conducted annually (in cohort I only). Anthropometric measurements included height, weight, triceps skinfold (TSF) and mid-upper-arm circumference (MUAC). Mid-upper-arm muscle area (MAMA) and mid-upper-arm fat area (MAFA) were calculated. The two cohorts were combined for analyses. The meat group showed the steepest rates of gain in MUAC and MAMA over time, and the milk group showed the next largest significant MUAC and MAMA gain compared with the plain githeri and control groups (P< 0·05). The meat group showed the least increase in TSF and MAFA of all groups. These findings have implications for increasing micronutrient intake and lean body mass in primary schoolchildren consuming vegetarian diets.

A randomized, controlled school feeding study was conducted in rural Embu District, Kenya to test for a causal link between animal-source food intake and changes in micronutrient nutrition and growth, cognitive, and behavioral outcomes. Twelve primary schools were randomly assigned to 1 of 4 groups. Children in Standard I classes received the local plant-based dish githeri as a midmorning school snack supplemented with meat, milk, or fat added to equalize energy content in all feedings. The Control children received no feedings but participated in data collection. Main outcome measures assessed at baseline and longitudinally were 24-h food intake recall, anthropometry, cognitive function, physical activity, and behaviors during school free play. For cognitive function, the Meat group showed the steepest rate of increase on Raven's Progressive Matrices scores and in zone-wide school end-term total and arithmetic test scores. The Plain githeri and Meat groups performed better over time than the Milk and Control groups (P < 0.02-0.03) on arithmetic tests. The Meat group showed the greatest increase in percentage time in high levels of physical activity and in initiative and leadership behaviors compared with all other groups. For growth, in the Milk group only younger and stunted children showed a greater rate of gain in height. The Meat group showed near doubling of upper midarm muscle area, and the Milk group a smaller degree of increase. This is the first randomized, controlled feeding study to examine the effect of meat- vs. milk- vs. plant-based snacks on functional outcomes in children.

Thousands of surveys on rural livelihoods in developing countries are being done every year. Unfortunately, many suffer from weaknesses in methods and problems in implementation. Quantifying households' dependence on multiple environmental resources (forests, bush, grasslands and rivers) is particularly difficult and often simply ignored in the surveys. The results therefore do not reflect rural realities. In particular, 'the hidden harvest' from natural resources is generally too important to livelihoods for development research, policies and practice to ignore. Fieldwork using state-of-the-art methods, and in particular well-designed household questionnaires, thus becomes an imperative to adequately capture key dimensions of rural welfare. This book describes how to do a better job when designing and implementing household and village surveys for quantitative assessment of rural livelihoods in developing countries. It covers the entire research process from planning to sharing research results. It draws on the experiences from a large global-comparative project, the Poverty Environment Network (PEN), to develop more robust and validated methods, enriched by numerous practical examples from the field. The book will provide an invaluable guide to methods and a practical handbook for students and professionals.

Differentiation of bloodstream-form trypanosomes into procyclic (midgut) forms is an important first step in the establishment of an infection within the tsetse fly. This complex process is mediated by a wide variety of factors, including those associated with the vector itself, the trypanosomes and the bloodmeal. As part of an on-going project in our laboratory, we recently isolated and characterized a bloodmeal-induced molecule with both lectin and trypsin activities from midguts of the tsetse fly, Glossina longipennis [Osir, E.O., Abubakar, L., Imbuga, M.O., 1995. Purification and characterization of a midgut lectin-trypsin complex from the tsetse fly, Glossina longipennis. Parasitol. Res. 81, 276-281]. The protein (lectin-trypsin complex) was found to be capable of stimulating differentiation of bloodstream trypanosomes in vitro. Using polyclonal antibodies to the complex, we screened a G. fuscipes fuscipes cDNA midgut expression library and identified a putative proteolytic lectin gene. The cDNA encodes a putative mature polypeptide with 274 amino acids (designated Glossina proteolytic lectin, Gpl). The deduced amino acid sequence includes a hydrophobic signal peptide and a highly conserved N-terminal sequence motif. The typical features of serine protease trypsin family of proteins found in the sequence include the His/Asp/Ser active site triad with the conserved residues surrounding it, three pairs of cysteine residues for disulfide bridges and an aspartate residue at the specificity pocket. Expression of the gene in a bacterial expression system yielded a protein (M(r) approximately 32,500). The recombinant protein (Gpl) bound d(+) glucosamine and agglutinated bloodstream-form trypanosomes and rabbit red blood cells. In addition, the protein was found to be capable of inducing transformation of bloodstream-form trypanosomes into procyclic forms in vitro. Antibodies raised against the recombinant protein showed cross-reactivity with the alpha subunit of the lectin-trypsin complex. These results support our earlier hypothesis that this molecule is involved in the establishment of trypanosome infections in tsetse flies.

A preliminary study of microbiological quality of honey was carried out using 26 samples obtained from the National Bee Keeping Research Station. Total viable counts (TVC) of aerobic bacteria, yeasts and moulds, and Clostridium species were done. Of the 26 samples, 24 (92.3%) had a TVC ranging from 3 x10 -87 x 10 colony forming units (cfu) per gram of honey. Two samples did not yield any microorganisms. Of the 24 positive samples, 9 (37.5%) were found to contain Clostridium species per gram while eight (33.3%) were positive for moulds with counts ranging from 10-100 c.f.u / g. No yeasts were detected. In addition, three samples yielded the three types of microorganisms.

Twenty variceal banding sessions were performed in eight patients between February 1995 and September 1996. A total of 69 rings were used to band the varices and at each session between two to six rings were used. Two of the eight had active bleeding and both underwent variceal banding to successfully arrest their bleeding as inpatients. Sixteen other variceal banding sessions were performed on an outpatient basis to obliterate their varices. Four of the eight patients had had sclerotherapy before and varices were still present. No acute or long term complications were noted. In one patient, variceal banding could not be performed as he developed stridor upon placement of the overtube. All the patients had advanced varices (Grade III or IV) and extended for more than 15 cms in the oesophagus. Endoscopic variceal obliteration remains the treatment of choice for patients with portal hypertension with variceal bleeding. Variceal banding is associated with a superior outcome when compared with sclerotherapy; the variceal kill time is shorter, infective complications less, rebleeding occurs less commonly and transfusion requirements are lower.

The microbiological quality of ground water (boreholes) and domestic tanks in five locations of Kikuyu Division, Kiambu District, was determined. Two boreholes and twelve domestic tanks were sampled from each location. Seven (70%) out of 10 boreholes were contaminated with faecal coliforms. Total bacterial counts ranged from 1 to 6280 per ml of water while the coliform counts ranged from 0 to 161. Out of 70 water samples screened for faecal coliforms, 63 (90%) were positive. Faecal Streptococci were isolated in 71% of the samples.

A prospective study of serial serum C-reactive protein (CRP) concentrations was made on 21 patients who had received renal allografts. CRP was raised during 27 of 32 rejection episodes and in all of five episodes of rejection associated with infection. CRP values were persistently elevated in three irreversible rejection episodes. Significantly raised CRP concentrations were documented in 14 of 20 episodes of infection. In some cases CRP was a predictive indicator of rejection or infection. In all cases of infection or rejection associated with a rise in CRP, CRP values fell following successful treatment with appropriate agents. Serial CRP measurement used in conjunction with other clinical and biochemical parameters appears to be valuable clinically following renal transplantation.

This report concerns an outbreak that occurred during July/August 1997. Ten pigs from a herd of 181 pigs in a medium-scale, semi-closed piggery in Kiambu District, Kenya, contracted the clinical disease. The main clinical findings in affected pigs included: fever (40.5-41.8 degrees C), prostration, inappetence, dog-sitting posture, abortion, erythema and raised, firm to the touch and easily palpated light pink to dark purple diamond-shaped to square/rectangular spots on the skin around the belly and the back. Based on the pathognomonic skin lesions, a clinical diagnosis of swine erysipelas was made. The diagnosis was confirmed by the isolation of Erysipelothrix rhusiopathiae organisms from the blood and skin biopsies taken from the affected pigs. Response to treatment with a combination of procaine penicillin and dihydrostreptomycin at the dosage rate of 20,000 IU/kg body weight (based on procaine penicillin) for 3 days was good and all the affected pigs recovered fully. The farm was placed under quarantine to prevent spread of the disease

Operations Research techniques involving modelling a situation or a problem and finding an optimal solution for it. These tools are not designed nor intended to replace managerial decision making, but rather their purpose is to aid in the decision-making process by providing a quantitative basis for decision making. Unfortunately, the proliferation of OR tools in organizational decision making has been lacking, with concerns been expressed about the limited awareness of the business community of OR's potential and capability. Current study was based in the premise that students provide an appropriate avenue, as agent of change, in sensitizing and demonstrating the potential and capacity of OR tools/techniques in resolving various problems, both in public and private sector. Study aimed at evaluating the use of OR as tools of data analysis at MBA level. A sample of 100 MBA research projects undertaken between 2005 and 2007 was randomly selected and their objectives and selected data analysis tools recorded. Where OR tools were not used, the research evaluated if there was a possibility of using OR tools. Results indicated low usage of OR as data analysis, though there was a high potential for the use of OR tools.

Oluoch-Kosura W, Siele DK, Owuor PO, Kavoi MM. "A Measure of Economic Rationality in the Smallholder Tea Sub-Sector in Kenya.". 2001. Abstract

The smallholder tea sub-sector in Kenya is considered the largest and one of the most successful smallholder schemes in the world. However, tea productivity in this sub-sector has been persistently low when compared with the estate sub-sector. Despite the smallholders planting high yielding clonal teas, the national average yield in the sub-sector was only 2,075 kg made tea/hectare (mt/ha) compared to 3,954 kg mt/ha in the estate sub-sector in 1998. This study investigated some of the factors contributing to low tea productivity in the sub-sector. Cross sectional data gathered in Kirinyaga, Nyambene, Nandi and Nyamira Districts in 1999 were used. It was hypothesized that the extend of rationality in allocation of resources in the smallholder tea enterprise is relatively low. Hence, smallholder tea productivity has remained relatively lower than in the estate sub-sector, high yielding clones and useful agronomic recommendations extended in the smallholder sub-sector notwithstanding. To determine \"the extend of economic rationality\", \"A Test of Economic Rationality Model\" was used whereby, the index of economic rationality, ρ is the product moment coefficient of correlation between log (total variable costs-excluding labour costs) and log (labour-in mandays) for each tea district and region. The results showed that the product moment coefficient of correlation, ρ was:- 0.647 in Kirinyaga District, 0.651 in Nyambene District, 0.793 in Nandi District, 0.743 in Nyamira District, 0.595 in East Rift Valley Region, 0.752 in West Rift Valley Region and 0.674 for all farms surveyed. It was noted that the lowest value of ρ was 0.595 in East Rift Valley Region. It means that at least 59 percent of the variance in the logs of both inputs is due to the variation in the systematic profit-maximizing component of these inputs. The balance of 41 percent is the maximum that could be occasioned not only by poor technology and/or knowledge gaps but also by errors in the model and noise in the universe. The null hypothesis was rejected in favour of the alternative hypothesis. The conclusion is that smallholder tea farmers in Kenya seem to be quite price efficient in tea production.

Lagerkvist CJ, Ngigi M, Okello J, Karanja N. "Means-End Chain approach to understanding farmers’ motivations for pesticide use in leafy vegetables: The case of kale in peri-urban Nairobi, Kenya.". 2012. Abstract

Peri-urban farmers play a significant role in the production of vegetables consumed in the urban centers in most African countries. The production of vegetables in the peri-urban areas in these countries is strategic with most farmers targeting the lucrative and better-paying urban markets. However, the decline in agricultural land in the peri-urban due to competition from housing for urban workers has led peri-urban farmers to use intensive means of agricultural production. Decreasing land sizes imply that peri-urban lands are continuously under production resulting in the build-up of pests and diseases. Further, the tropical climate generally increases the outbreak and rapid multiplication of pests and diseases. These problems and the urban consumers’ demand for clean and spotlessness vegetables encourage the excessive use of pesticides. Additionally, the desire to reduce losses and waste can cause farmers to violate the recommended intervals between pesticide application and harvest. Consequently, there have been concerns about the excessive application of pesticides in vegetables produced in the peri-urban areas. The study applies the Means-End Chain (MEC) approach accompanied by the laddering technique to assess the motivations for peri-urban farmers to use pesticides as opposed to other crop protection methods in the production of fresh vegetables. It specifically examines the relevant attribute econsequenceevalue relations by setting up relevant hierarchical value maps. The study is based on a random sample of 54 kale farmers in three peri-urban areas of Nairobi. It finds that farmers apply pesticides at different times mainly for the purpose of improving their efficacy in protecting kale against pests and diseases. Protection of kale improves its aesthetic quality attributes resulting in higher prices and hence profit margins. Examination of the hierarchal value maps further reveals that the other motivations for pesticide use include benevolence value (being helpful and honest to trading partners), power (social recognition or good reputation as a good farmer), hedonism (happiness for being a successful farmer), security (having good health) and self-direction (independence or being self-supporting from vegetable income). Clearly, the motivations suggest a dilemma in safe use of pesticides. While some motivators dictate less use of pesticides, others can promote indiscriminate use of pesticides. The study discusses the implication of these findings for sustainable and environmentally friendly production of safe leafy vegetables in peri-urban areas.

The effect of acqueous extract of the tuber of Adenia globosa on the isolated preparation of the rat uterus was determined. The crude drug caused a dose-dependent contraction of the tissue preparation. This action was enhanced by a small dose of oxytocin. The results are discussed in relation to the traditional uses of this plant.
Largerkvist CJ, Ngigi MW, Karanja N. "Means-end chain analysis explains soil fertility management decisions by peri-urban vegetable growers in Kenya.". 2013. Abstract

Past studies of the use of soil fertility management strategies by farmers usually model input use decisions based on the neoclassical utility/profit maximization principle in which farmers use soil fertility management inputs primarily to increase revenues and profits. However, there is, to date, no study that explains exactly how this decision-making process occurs and the role which personal values play in driving the choice of soil fertility management inputs. This article systematically maps the relationship between choice of soil fertility management strategy (attributes), its outcomes (consequences) and the personal values that motivate the choice. It specifically uses the means-end chain approach to construct hierarchical value maps that relate the attributes to consequences, and ultimately to the personal values. The study finds that the use of soil fertility management strategies by peri-urban fresh vegetable growers is driven by five personal values, namely happiness, comfortable life, independence, good/healthy life and achievement of life goals. It also finds that while farmers seek to increase profit (hence incomes), profit maximization is not the end driver of the use of soil fertility management inputs. It concludes that a lot more goes into farmers’ decision-making process relating to the use of soil fertility management practices than can be explained by the neoclassical profit/utility maximization principle. The study discusses the policy implications of these findings.

Bovine foscioliosis coused by F. giganticais widespread in   There is a large collection of reports of fasciolosis in Kenya based on  abattoir data records from veterinary investigation laboratories (VILS) as well as reports on a few farm study was carried out to improve on the reports.  Diagnosis of fasciola infection has traditionally been based on detection of typical eggs in the faeces.  A variety of other techniques are now available eg enzyme-linked immunosorbent assay (ELISA), which has shown to be sensitive and useful. Three agro-ecological zoned were defined depending on the reported prevalence; high risk, medium risk and low risk zones.  Two study districts were picked at random from each zone.  The study farms were selected using the two stage cluster sampling. Faecal and blood samples were collected on the farm.  Serum was later harvested.  ELISA and faecal sedimatation tests (FST) were carried out. A total of 2434 faecal and blood samples were screened.  ELISA achieved the highest (66%) positive rate of the samples from Kwale district and the lowest (23%) rate in Nakuru.  An overall positive prevalence of (43%) for fasciolosis was achieved.  The faecal sedimentation test showed prevalence of 19%.  In both tests high prevalence were observed in Kwale and Kilifi districts.  ELSA was always positive when FST was positive but not the converse. The on-famr survey utilizing two reliable diagnostic tests was meant to improve on existing abattoir reports.  Both tests showed fair to good agreements.  The higher detection by ELISA might be due to deworming and other reasons.  It was concluded that on-farm surveys are better than retrogressive studies; thought the latter are cheaper and faster.,  the current prevalence of fasciolosis are different from past reports with coastal showing higher than expected prevalences.

"MDR1 pharmacogenetics: frequency of the C3435T mutation in exon 26 is significantly influenced by ethnicity." Pharmacogenetics. 2001;11(3):217-21. Abstract

P-glycoprotein (PGP), the product of the multidrug resistance gene (MDR1), acts as an energy-dependent efflux pump that exports its substrates out of the cell. PGP expression is an important factor regulating absorption of a wide variety of medications. It has also been associated with intrinsic and acquired cross resistance to a number of structurally unrelated anticancer drugs. A single nucleotide polymorphism (SNP) in exon 26 of the MDR1 gene, C3435T, was recently correlated with PGP protein levels and substrate uptake. Individuals homozygous for the T allele have more than four-fold lower PGP expression compared with CC individuals. As overexpression of PGP has been associated with altered drug absorption, therapy-resistant malignancies, and lower concentrations of HIV-1 protease inhibitors, this SNP may provide a useful approach to individualize therapy. To facilitate clinical application throughout the world, 1280 subjects from 10 different ethnic groups were evaluated for this SNP using the polymerase chain reaction-restriction fragment length polymorphism assay and the genotype and allele frequency for each group were ascertained. Marked differences in genotype and allele frequency were apparent between the African populations and the Caucasian/Asian populations (P < 0.0001). The Ghanaian, Kenyan, African American and Sudanese populations studied had frequencies of 83%, 83%, 84% and 73%, respectively, for the C allele. The British Caucasian, Portuguese, South-west Asian, Chinese, Filipino and Saudi populations had lower frequencies of the C allele compared to the African group (48%, 43%, 34%, 53%, 59%, and 55%, respectively). The high frequency of the C allele in the African group implies overexpression of PGP and may have important therapeutic and prognostic implications for use of PGP dependent drugs in individuals of African origin.

OBJECTIVES. The purpose of this study was to identify health-care seeking and related behaviors relevant to controlling sexually transmitted diseases in Kenya. METHODS. A total of 380 patients with sexually transmitted diseases (n = 189 men and 191 women) at eight public clinics were questioned about their health-care seeking and sexual behaviors. RESULTS. Women waited longer than men to attend study clinics and were more likely to continue to have sex while symptomatic. A large proportion of patients had sought treatment previously in both the public and private sectors without relief of symptoms, resulting in delays in presenting to study clinics. For women, being married and giving a recent history of selling sex were both independently associated with continuing to have sex while symptomatic. CONCLUSIONS. Reducing the transmission of sexually transmitted diseases in Kenya will require improved access, particularly for women, to effective health services, preferably at the point of first contact with the health system. It is also critical to encourage people to reduce sexual activity while symptomatic, seek treatment promptly, and increase condom use.

Department of Medicine, College of Health Sciences, University of Nairobi. Characteristics of 14 patients above 12 years of age with congenital polycystic liver disease attending liver clinic at KNH were analysed. The diagnosis was mainly based on ultrasonographic findings. The disease was found predominantly among the Kikuyu ethnic group with a female/male ratio of 6:1 and the peak age at presentation was in the 5th decade. The liver function tests were essentially normal in all cases with no complication directly relating to liver disease. Hypertension was found in 78.6% of cases and chronic renal failure in 35.7% of cases. There was an associated polycystic disease in at least one other abdominal organ in all cases.

Interest in renal disease and practice in East Africa started as far back as the first quarter of this century. Work in this colonial era concentrated on establishing the existence of renal diseases and identifying the nature and incidence of these diseases. This was achieved by case identification and reporting as well as retrospective studies on post mortem and medical notes. The post independence period has not only identified the existence of even more renal diseases but also concentrated on getting a deeper understanding of the aetiology, nature, pattern, regional variations, complications and outcome of these diseases as seen in our environment. Apart from the better understanding of the prevalent renal diseases, emphasis has also been put on the expansion and delivery of renal services. Investigative and treatment facilities have been improved and a lot has been put into the training of the required local team of experts to man these services. This article reviews what has gone on in the last 70 years from the pure case-report and postmortem reports era to the era of locally available modern facilities including haemodialysis, peritoneal dialysis and kidney transplantation.

In 7 years (1981-1988) at the Kenyatta National Hospital (KNH), Nairobi the diagnosis of systemic lupus erythematosus (SLE) was made in 67 patients. In 23 of these patients lupus nephritis complicated the SLE. Lupus nephritis was diagnosed through renal biopsy, haematuria and proteinuria in urine with positive lupus erythematosus (LE) cell phenomenon. The histology found in these patients included 5 patients with minimal lesion, 7 patients with membranous, 3 with focal, 4 with diffuse, 3 with crescenteric and one with membranoproliferative glomerulonephritis. While patients with minimal, membranous and focal nephritis had general good outlook on low dose maintenance or intermittent high dose steroid therapy the others with diffuse, crescenteric and membranoproliferative nephritis had poor prognosis. Patients with diffuse proliferative, membranoproliferative and crescenteric nephritis tended to have septicaemia, pulmonary oedema, fluid overload and chronic renal failure with poor prognosis. These patients responded poorly to oral and parenteral steroid therapy whether high or low dose.

In a one year period (March 1990 to March 1991) the pattern of diseases in geriatric patients (over 60 years of age) admitted to the medical wards at Kenyatta National Hospital (KNH) was studied. In all, there were 1296 patients (M:F = 1.7:1) in this age group forming 11.5% of all admissions during the study period. 1008 (77.8%) of the geriatric patients were between 60 and 79 years of age. Most of the admissions (86.4%) were first admissions. The mean number of diseases per geriatric patient was 1.4. Hypertension and Cardiomyopathy were the commonest single diseases recorded, making up 43.9% of all diseases in this patient population. The commonest neurological diagnosis was stroke, which occurred in a setting of hypertension or cardiomyopathy in all the patients in whom it was diagnosed. The mean duration (+/- 2SD) of stay in the hospital in this patient population was 43 (+/- 19) days. Eighty eight (6.8%) of the patients died, the commonest cause of death being heart failure due to cardiomyopathy or hypertensive heart disease. It is concluded that geriatric patients form a sizeable proportion of our medical admissions and that a large proportion suffer from diseases of the cardiovascular system. It is thus recommended that further studies be carried out on the pattern of diseases in such patients and optimal management strategies for their ailments be outlined.

In a fifteen month period (August 1987 to November 1988) forty patients requiring haemodialysis had 83 angioaccess procedures performed. Arteriovenous (AV) shunts and arteriovenous fistulae were the commonest procedures, comprising 56 (67%) and 20 (24%) of the patients respectively. Subclavian catheters and artificial grafts were used less frequently. Nephrologists and senior house officers attached to the Renal Unit were responsible for fashioning A-V shunts and inserting subclavian catheters while the A-V fistulae were fashioned by the urologists and vascular surgeons. The commonest complication of A-V shunts were clotting, occurring in 31 (55.4%) followed by bleeding in 14 (25%). Eight (32%) of the A-V fistulae never functioned from the beginning. It is noted that we are still very dependent on A-V shunts for vascular access in end stage renal disease (ESRF) patients and this is associated with an unacceptable level of complications. This dependency on A-V shunts in ESRD patients should be stopped or phased out. A-V fistulae should be used more frequently. Their constructions should be well thought out, executed and supervised by the few surgeons who are versed in them together with their follow-ups.

One hundred consecutive patients with diabetic ulcers were studied in an 8-month-period. There were 58 females. The mean age was 59.9 years. Eighty three patients had non-insulin dependent diabetes mellitus. The mean duration of diabetes mellitus was 11.6 years. The mean duration of the ulcer was 8.5 months. Sixty nine of the ulcers were gangrenous. Over 50% of the ulcers involved the big toes. Neuropathic ulcers were found mainly in the sole of the feet. Roentgenograms showed evidence of osteomyelitis in 44 patients. There were 356 bacterial isolates (340 aerobes and 16 anaerobes) from the ulcers. There were 3.6 infecting organisms per ulcer in gangrenous ulcers, while in neuropathic ulcers, there were 3.4 infecting organisms per ulcer. In both types of ulcer Staphylococcus aureus and Escherichia coli were the commonest infecting organisms each being isolated in 88 of the 100 ulcers studied. In repeat bacterial cultures at 4 weeks there were 116 bacterial isolates. Staphylococcus aureus persisted in 63 ulcers despite therapy, while Escherichia coli persisted in 35. There were no new organisms isolated at repeat cultures and no ulcer was completely sterile. The Staphylococcus aureus was 100% sensitive to Augmentin (Amoxicillin plus clavulinic acid), Clindamycin, Novobiocin, and Amikacin while the gram negative bacilli were sensitive to Cefotaxime, Piperacillin, Amikacin and augmentin, Clindamycin, Chloramphenicol and Lincomycin inhibited the growth of anaerobes to a varying degree.

Acute renal failure (ARF) complicated the use of traditional herbal remedies in six adult patients seen at Kenyatta National Hospital in a 2-year period (August 1984 to August 1986). This comprised 10.9% of all the cases of ARF and 24% of the cases of ARF due to medical causes. All the patients were oliguric and the period of oliguria in the four patients who survived ranged between 19-57 days (mean 26.3 days). Five of the patients had evidence of fluid overload. The blood urea nitrogen and serum creatinine were elevated in all the patients. The serum sodium was normal in all, while the serum potassium was elevated in 2 cases. Identity of the herbal medication was unknown in all the cases. The indication was abdominal pain in 4 cases, infertility and abdominal pain in one and prophylaxis against witchcraft in the other. All the patients were started on haemodialysis, two of them having had periods of peritoneal dialysis for 12 and 16 days. Two patients died. Of the four surviving patients, follow up has been carried out for 8, 6, 5 and 4 months. At four months follow up the creatinine clearance in the 4 surviving patients have been 54, 63, 51 and 43 ml/min.

A prospective study to determine the prevalence and profile of cardiovascular disease in elderly patients admitted into the medical wards, Kenyatta National Hospital, was carried out between July 1991 and January 1992. Two hundred and two patients over 60 years of age were admitted into the medical wards over this period. This formed seven per cent of the total medical admissions. Two of these refused to take part in the study. Of the 200 elderly patients evaluated for cardiovascular disease, 146 (73%) were between 60 and 75 years of age with only 26 (13%) being over 85 years. Fifty seven per cent were males. Clinical evidence of cardiovascular disease was present in 79 (39.5%) of the patients evaluated. There was no sex difference in the prevalence of cardiovascular disease as judged from clinical evaluation (37.7% males versus 41.9% females, p > 0.05). Cardiovascular diseases in our medical in-patients at Kenyatta National Hospital are common and especially so with hypertension which plays an important role in the aetiology of congestive heart failure and cerebravascular accidents. Cardiac arrhythmias are also common though not necessarily symptomatic. Rheumatic heart disease and cardiomyopathies were uncommon in our study population. A community-based survey is needed to determine the true prevalence of cardiovascular diseases in the elderly and their contribution to morbidity in this sector of the population.

The currently available evidence suggest that diuretics and/or low dose dopamine increases renal blood flow (RBF), glomerular filtration rate (GFR) and natriuresis in experimental animals, and limits ATP utilisation and oxygen needs in nephron segments at high risk of ischaemic injury, actions that could potentially limit renal injury and accelerate recovery in acute renal failure (ARF). These effects have indeed been confirmed in most experimental animals while using mannitol or low dose dopanime. Frusemide, however, for unknown reasons, has been effective in some animal models, but not others. In humans, it can be said that diurectics have a limited value to prevent, reverse or speed recovery from acute renal failure. Most clinical studies have failed to demonstrate convincingly that low dose dopamine either prevents ARF in high risk patients or improves renal function or outcome in patients with established ARF. This confusing scenario is further complicated by the fact that both diuretics and low dose dopamine can result in severe metabolic and cardiovascular complications in critically ill patients.

We present two cases of neurofibromatosis type 1 (NF-1), one a 35 year old male who first recognised his problem at the age of fifteen years and at the time of assessment, satisfied the National Institute of Health (NIH) diagnostic criteria for NF-1 and had a nodular plexiform neurofibroma involving the left fifth dorsal nerve root and a diffuse plexiform neurofibroma involving the left lower limb. The second patient, a 45 year old female recognised her problem at the age of 39 years, did not quite satisfy the NIH diagnostic criteria for NF 1 and had diffuse plexiform neurofibroma involving both lower limbs and buttocks almost symmetrically, a finding which has not previously been described to the best of our knowledge.

Fine-needle aspiration (FNA) is a well-recognized technique for sampling solid organs. It is used in renal transplantation to clarify the cause of a poorly functioning graft. Differential scoring techniques with respect to peripheral blood cell populations, and immunocytochemistry have been employed in this context. We describe the use of simple morphological criteria alone in renal transplant FNA. We compare these with needle biopsy and clinical parameters and show their value in the detection of active cellular rejection. Their limitations are discussed within the framework of other patterns of transplant pathology.

Renal transplantation has become the most effective treatment for end stage renal failure. The numbers and survival rates of patients undergoing renal transplantation have increased immensely over the past decade. The use of immunosuppressive drugs has contributed greatly to the success of transplantation. Drugs such as azathioprine, corticosteroids, cyclosporin, FK 506, ATG/ALG and OKT3 are being used in several countries on a daily basis. New drugs and other modalities of immunosuppression are under investigation. This paper reviews these medications with respect to dosing, administration and adverse effects. Drugs being relatively expensive, the use of these drugs in developing counties is discussed.

Renal biopsies were evaluated in 422 patients with nephrotic syndrome at the Kenyatta National Hospital between 1982 and 1993. Three hundred and fifty five (84.1%) of the patients were less than 30 years old (range: 7 months to 66 years; mean=SD: 28.4 - 9.2 years). The commonest histological lesions were mesangial proliferative glomerulonephritis (25.1%), minimal change nephropathy (17.5%) and focal segmental glomerulosclerosis (15.2%). Poststreptococcal aetiology was implicated in diffuse proliferative glomerulonephritis while use of skin lightening cosmetics appeared to play a role in the aetiology of minimal change nephrophathy in females. No aetiological role was apparent for hepatitis B virus, human immunodeficiency virus, malarial or schistosomal infection. All patients with minimal change nephropathy, focal segmental glomerulosclerosis and mesangial proliferative glomerulonephritis were treated with steroids and/or cytotoxics with a variable response.

We present what we believe is the first case of pregnancy occurring in a patient on CAPD, and indeed end stage renal disease (ESRD), in Kenya. Pregnancy progressed very well until the thirtieth week when foetal movements and heart sounds were noted to be absent and this was confirmed by sonography. A macerated still birth was delivered per vagina following induction of labour. We review the literature on this rare occurrence and discuss the possible causes of the unpleasant outcome in our patient.

In a 6 year period (1984-1989) we have had the opportunity to take care of five patients who had nephrotic syndrome and became pregnant. Four of them had mesangial proliferative glomerulonephritis while one had focal segmental glomerulosclerosis. Four of the pregnancies went to term while one was terminated at 34 weeks gestation because of deteriorating renal function in the mother. All the pregnancies ended in delivery of normal babies. However, two patients have since died of end stage renal disease, while the remaining three continue to be nephrotic with reduced levels of renal function following the deliveries.

In a two-year-period (August 1984 to August 1986), 77 patients were admitted into the maintenance haemodialysis programme at Kenyatta National Hospital. 24 (31.5%) of these had ascites during haemodialysis. Nine (37.5%) of the patients who had ascites had prior peritoneal dialysis, while 15 (62.5%) had congestive cardiac failure at the time of development of the ascites. In 21 (87.5%), the ascites responded to therapy with diuretics, salt and fluid restriction, antibiotics when indicated and to ultrafiltration during dialysis. In 3 (12.5%) of the patients, the ascites developed in the absence of any predisposing cause. The ascites progressively increased in amount and was associated with marked wasting. These patients were considered to have refractory ascites of haemodialysis.

A 50-year-old female presented with a five months history of recurrent attacks of dizziness, sweatiness, tremors and fainting with loss of consciousness. These were found to be due to hypoglycaemic episodes with blood sugars less than 1 mmol/l and were treated as such. A diagnosis of insulinoma was initially considered, but the patient turned out to have fibrosarcoma of the lung, a rare lung tumour. She also had finger and toe clubbing and features of hypertrophic pulmonary osteoarthropathy.

Abstract
Renal transplantation is not readily available in the majority of countries in Africa. It is expensive and difficult to sustain on the meagre funds allocated to health. We report our short experience with fifteen living donor recipients followed in our unit for at least 24 months, range 26 - 48 (mean 35 months) post-transplantation. The donors and recipients were mostly young adults with mean ages of 36.7 years and 32.6 years respectively. The majority of the donors and recipients were males. The donors in most cases were siblings. Within this time, one graft has been lost at one year and the patient restarted on haemodialysis. Three patients died, two within the first year, the third at 23 months after transplantation, all with functioning grafts. The one year graft and patient survival rates were 93% and 86.6% respectively. The second year graft survival rates remained at 93% and the patients survival rate 80%. The nature and frequency of complications seen in these patients is comparable to those in other centres. Of all medical complications, bacterial infections contributed 69.4% of all infections. Cardiovascular complications comprised 31.25% of the complications. Hypertension seen in 85.5% of the patients accounted for 65% of the cardiovascular complications. Acute rejections were common and occurred in seven patients. Transplantation is a viable mode of renal replacement therapy (RRT) in our environment. The practice should be supported to make it more readily available to the many young end stage renal failure (ESRF) patients.

Forty seven patients with acute renal failure were studied prospectively over a two-year period at the Kenyatta National Hospital. There were 20 males and 27 females. The mortality rate was 40.4%. Most patients had medically oriented problems. Complications that were associated with a high mortality were infections and the presence of neuropsychiatric manifestations.

In a one year period (March 1990 to March 1991) the pattern of diseases in geriatric patients (over 60 years of age) admitted to the medical wards at Kenyatta National Hospital (KNH) was studied. In all, there were 1296 patients (M:F = 1.7:1) in this age group forming 11.5% of all admissions during the study period. 1008 (77.8%) of the geriatric patients were between 60 and 79 years of age. Most of the admissions (86.4%) were first admissions. The mean number of diseases per geriatric patient was 1.4. Hypertension and Cardiomyopathy were the commonest single diseases recorded, making up 43.9% of all diseases in this patient population. The commonest neurological diagnosis was stroke, which occurred in a setting of hypertension or cardiomyopathy in all the patients in whom it was diagnosed. The mean duration (+/- 2SD) of stay in the hospital in this patient population was 43 (+/- 19) days. Eighty eight (6.8%) of the patients died, the commonest cause of death being heart failure due to cardiomyopathy or hypertensive heart disease. It is concluded that geriatric patients form a sizeable proportion of our medical admissions and that a large proportion suffer from diseases of the cardiovascular system. It is thus recommended that further studies be carried out on the pattern of diseases in such patients and optimal management strategies for their ailments be outlined.

The currently available evidence suggest that diuretics and/or low dose dopamine increases renal blood flow (RBF), glomerular filtration rate (GFR) and natriuresis in experimental animals, and limits ATP utilisation and oxygen needs in nephron segments at high risk of ischaemic injury, actions that could potentially limit renal injury and accelerate recovery in acute renal failure (ARF). These effects have indeed been confirmed in most experimental animals while using mannitol or low dose dopanime. Frusemide, however, for unknown reasons, has been effective in some animal models, but not others. In humans, it can be said that diurectics have a limited value to prevent, reverse or speed recovery from acute renal failure. Most clinical studies have failed to demonstrate convincingly that low dose dopamine either prevents ARF in high risk patients or improves renal function or outcome in patients with established ARF. This confusing scenario is further complicated by the fact that both diuretics and low dose dopamine can result in severe metabolic and cardiovascular complications in critically ill patients.

Four hundred and three teenage secondary school students (50.6% males) from two girls' and two boys' Nairobi City Schools, selected by stratified sampling, were screened to determine the prevalence of proteinuria, haematuria, nitrituria and hypertension. Nine students (2.2%) had significant proteinuria while 14 (3.5%) had microscopic haematuria. Two students had combined proteinuria and haematuria. There was no statistically significant difference in the prevalence of proteinuria and/or haematuria between the sexes. Other urinary abnormalities detected were leucocyturia in 14(3.5%) and nitrites in four (1%). Leucocyturia was commonner in females (p = 0.001). Cloudy urinary appearance was significantly associated with the presence of leucocyturia (p = 0.0028) and proteinuria (p = 0.0276). Neither personal history of recurrent sore throat and skin infections nor family history of hypertension, diabetes mellitus or kidney disease was significantly associated with proteinuria or haematuria. Blood pressure tended to increase with age. Mean systolic and diastolic blood pressures were significantly higher in boys than girls in the age group 15-18 years (P < 0.001). Of the 397 students whose blood pressures were measured, four (1%) were found to be hypertensive. Weight and body mass index were strong positive correlates of blood pressure. The prevalence of proteinuria, haematuria, other urinary abnormalities and hypertension ranges between 1% and 3.5% among teenage secondary school children. The majority are asymptomatic and have no significant associations. It is recommended that routine urinalysis and blood pressure measurements should be part of the school health service so as to identify asymptomatic students who require close monitoring and/or intervention.

Forty females, age 14 to 35 years (mean 28.6 years) with chronic renal failure (CRF) were included in the study. Their menstrual patterns were noted. The function of their hypothalamo-pituitary-ovarian axis was assessed by the serum levels of follicle stimulating hormone (FSH), Luteinising hormone (LH), prolactin (PrL), estradiol (E2) and progesterone (P) at different phases of the menstrual cycle in patients who continued to have normal menses (Group 1) and at weekly intervals for six weeks in patients with menstrual disturbances (Group II). The mean hormone levels during the initial contact Luteal phase in group I were FSH 12.0 IU/L (N, 1.0-3.0 IU/L), LH 1.8IU/L (N 1.5-101U/L), PrL 652mIU/L (N, 100-600 mIU/L) mE2 160 pmol/L (N 400-1400 pmol/L) and P5 nmol/L (N 14-60 nmol/L) for group I. Corresponding values for group II were 1.2, 10.3, 250, 600 and 3.0 in relevant units. All patients (fourteen) with end stage renal disease (ESRD) had amenorrhoae. On the other hand, most patients with stable CRF (22/26) had normal menses. Following initiation of therapy (conservative or dialytic), there was no significant alteration in the hormonal profile or menstrual pattern. We conclude that other factors apart from the hormonal imbalances, may be responsible for the menstrual disturbances noted in patients with CRF.

In 7 years (1981-1988) at the Kenyatta National Hospital (KNH), Nairobi the diagnosis of systemic lupus erythematosus (SLE) was made in 67 patients. In 23 of these patients lupus nephritis complicated the SLE. Lupus nephritis was diagnosed through renal biopsy, haematuria and proteinuria in urine with positive lupus erythematosus (LE) cell phenomenon. The histology found in these patients included 5 patients with minimal lesion, 7 patients with membranous, 3 with focal, 4 with diffuse, 3 with crescenteric and one with membranoproliferative glomerulonephritis. While patients with minimal, membranous and focal nephritis had general good outlook on low dose maintenance or intermittent high dose steroid therapy the others with diffuse, crescenteric and membranoproliferative nephritis had poor prognosis. Patients with diffuse proliferative, membranoproliferative and crescenteric nephritis tended to have septicaemia, pulmonary oedema, fluid overload and chronic renal failure with poor prognosis. These patients responded poorly to oral and parenteral steroid therapy whether high or low dose.

In a six month period at the Kenyatta National Hospital, 46 patients (30 males) with chronic renal failure (CRF) and 22 healthy subjects have had a clinical and echocardiographic study of their cardiovascular systems. The patients with CRF were further classified as stable or in end stage renal disease (ESRD), the latter group requiring dialysis. Hypertension and circulatory congestion were the commonest clinical cardiovascular findings in patients with CRF. The patients with ESRD had significantly higher blood urea nitrogen and serum creatinine than the ones with stable CRF. Echocardiographically right ventricular size, left atrial size, aortic root diameter, left ventricular internal diameters, left ventricular end diastolic and systolic volumes, stroke volume, cardiac output, left ventricular posterior wall and interventricular septal thickness, ejection time and mitral and aortic peak flow rates were significantly higher in patients with CRF than in controls. In contrast, the circumferential fibre shortening and the ejection fraction were reduced in patients with CRF. Global left ventricular dysfunction was found in 47.8% of the patients. Using doppler flow studies, valvular incompetence was detected in a number of patients, mitral regurgitation being found in 84%.76% of the patients with CRF had varying degrees of pericardial effusion. The echocardiographic abnormalities and the pericardial effusions responded six weeks of haemodialysis in a variable manner.

Nine students (2.2%) had significant proteinuria while 14 (3.5%) had microscopic haematuria. Two students had combined proteinuria and haematuria. There was no statistically significant difference in the prevalence of proteinuria and/or haematuria between the sexes. Other urinary abnormalities detected were leucocyturia in 14(3.5%) and nitrites in four (1%). Leucocyturia was commonner in females (p = 0.001). Cloudy urinary appearance was significantly associated with the presence of leucocyturia (p = 0.0028) and proteinuria (p = 0.0276). Neither personal history of recurrent sore throat and skin infections nor family history of hypertension, diabetes mellitus or kidney disease was significantly associated with proteinuria or haematuria. Blood pressure tended to increase with age. Mean systolic and diastolic blood pressures were significantly higher in boys than girls in the age group 15-18 years (P < 0.001). Of the 397 students whose blood pressures were measured, four (1%) were found to be hypertensive. Weight and body mass index were strong positive correlates of blood pressure. The prevalence of proteinuria, haematuria, other urinary abnormalities and hypertension ranges between 1% and 3.5% among teenage secondary school children. The majority are asymptomatic and have no significant associations. It is recommended that routine urinalysis and blood pressure measurements should be part of the school health service so as to identify asymptomatic students who require close monitoring and/or intervention.

Interest in renal disease and practice in East Africa started as far back as the first quarter of this century. Work in this colonial era concentrated on establishing the existence of renal diseases and identifying the nature and incidence of these diseases. This was achieved by case identification and reporting as well as retrospective studies on post mortem and medical notes. The post independence period has not only identified the existence of even more renal diseases but also concentrated on getting a deeper understanding of the aetiology, nature, pattern, regional variations, complications and outcome of these diseases as seen in our environment. Apart from the better understanding of the prevalent renal diseases, emphasis has also been put on the expansion and delivery of renal services. Investigative and treatment facilities have been improved and a lot has been put into the training of the required local team of experts to man these services. This article reviews what has gone on in the last 70 years from the pure case-report and postmortem reports era to the era of locally available modern facilities including haemodialysis, peritoneal dialysis and kidney transplantation.

End stage renal disease requiring renal replacement therapy is a common complication of several renal diseases that are seen in the tropics. World over, the costs of the various modalities of therapy that constitute renal replacement therapy, including hemodialysis, continuous ambulatory peritoneal dialysis and renal transplantation, is prohibitive. All the above modes of therapy are provided in Kenya, unlike most countries with similar level of socioeconomic development. This article analyses the factors behind the limited success that renal replacement therapy enjoys in Kenya, which is faced with more pressing basic problems of malnutrition and infection.

Department of Medicine, College of Health Sciences, University of Nairobi. Characteristics of 14 patients above 12 years of age with congenital polycystic liver disease attending liver clinic at KNH were analysed. The diagnosis was mainly based on ultrasonographic findings. The disease was found predominantly among the Kikuyu ethnic group with a female/male ratio of 6:1 and the peak age at presentation was in the 5th decade. The liver function tests were essentially normal in all cases with no complication directly relating to liver disease. Hypertension was found in 78.6% of cases and chronic renal failure in 35.7% of cases. There was an associated polycystic disease in at least one other abdominal organ in all cases.

In a one year period (March 1990 to March 1991) the pattern of diseases in geriatric patients (over 60 years of age) admitted to the medical wards at Kenyatta National Hospital (KNH) was studied. In all, there were 1296 patients (M:F = 1.7:1) in this age group forming 11.5% of all admissions during the study period. 1008 (77.8%) of the geriatric patients were between 60 and 79 years of age. Most of the admissions (86.4%) were first admissions. The mean number of diseases per geriatric patient was 1.4. Hypertension and Cardiomyopathy were the commonest single diseases recorded, making up 43.9% of all diseases in this patient population. The commonest neurological diagnosis was stroke, which occurred in a setting of hypertension or cardiomyopathy in all the patients in whom it was diagnosed. The mean duration (+/- 2SD) of stay in the hospital in this patient population was 43 (+/- 19) days. Eighty eight (6.8%) of the patients died, the commonest cause of death being heart failure due to cardiomyopathy or hypertensive heart disease. It is concluded that geriatric patients form a sizeable proportion of our medical admissions and that a large proportion suffer from diseases of the cardiovascular system. It is thus recommended that further studies be carried out on the pattern of diseases in such patients and optimal management strategies for their ailments be outlined.

Abstract
Persistent microcytosis was noted among a number of post renal transplant patients attending the transplant clinic at the Western General Hospital Edinburgh. We retrospectively looked at the pattern of recovery of the anaemia of chronic renal failure following successful renal transplantation with good graft function (Creatinine less than 250 (mol/l). Comparisons were made between those patients with persistent microcytosis and those with normal mean cell volume (MCV). Patients with microcytosis tended to have a slower recovery compared to those with normal MCV especially from week 12 to 21 after transplantation with corresponding Hb changes of 108+ 20 to 126+/-20 g/l vs 128+ 17 to 144+/-19 g/l ([P < 0.05], 95% confidence limits). The microcytic groups also tended to have had poorer graft function with serum creatinines significantly higher than those with normal MCV from week 8 to 21, 182+/- 62 to 173+/- 51 (mol/1 vs 139+/- 40 to 149+/- 38 (mo1/L ([P < 0.05] 95% confidence limits). In both groups haemoglobin concentration was negatively correlated to serum creatinine. (r=-0.54, [P < 0.05]). Body iron status studies had not been done in these patients. Persistent microcytosis though a non sensitive marker of iron deficiency may be a marker of disordered iron metabolism in patients with poorer graft functions.

Renal transplantation is not readily available in the majority of countries in Africa. It is expensive and difficult to sustain on the meagre funds allocated to health. We report our short experience with fifteen living donor recipients followed in our unit for at least 24 months, range 26 - 48 (mean 35 months) post-transplantation. The donors and recipients were mostly young adults with mean ages of 36.7 years and 32.6 years respectively. The majority of the donors and recipients were males. The donors in most cases were siblings. Within this time, one graft has been lost at one year and the patient restarted on haemodialysis. Three patients died, two within the first year, the third at 23 months after transplantation, all with functioning grafts. The one year graft and patient survival rates were 93% and 86.6% respectively. The second year graft survival rates remained at 93% and the patients survival rate 80%. The nature and frequency of complications seen in these patients is comparable to those in other centres. Of all medical complications, bacterial infections contributed 69.4% of all infections. Cardiovascular complications comprised 31.25% of the complications. Hypertension seen in 85.5% of the patients accounted for 65% of the cardiovascular complications. Acute rejections were common and occurred in seven patients. Transplantation is a viable mode of renal replacement therapy (RRT) in our environment. The practice should be supported to make it more readily available to the many young end stage renal failure (ESRF) patients.

In a six month period at the Kenyatta National Hospital, 46 patients (30 males) with chronic renal failure (CRF) and 22 healthy subjects have had a clinical and echocardiographic study of their cardiovascular systems. The patients with CRF were further classified as stable or in end stage renal disease (ESRD), the latter group requiring dialysis. Hypertension and circulatory congestion were the commonest clinical cardiovascular findings in patients with CRF. The patients with ESRD had significantly higher blood urea nitrogen and serum creatinine than the ones with stable CRF. Echocardiographically right ventricular size, left atrial size, aortic root diameter, left ventricular internal diameters, left ventricular end diastolic and systolic volumes, stroke volume, cardiac output, left ventricular posterior wall and interventricular septal thickness, ejection time and mitral and aortic peak flow rates were significantly higher in patients with CRF than in controls. In contrast, the circumferential fibre shortening and the ejection fraction were reduced in patients with CRF. Global left ventricular dysfunction was found in 47.8% of the patients. Using doppler flow studies, valvular incompetence was detected in a number of patients, mitral regurgitation being found in 84%.76% of the patients with CRF had varying degrees of pericardial effusion. The echocardiographic abnormalities and the pericardial effusions responded six weeks of haemodialysis in a variable manner.

AIMS: Dihydropyrimidine dehydrogenase (DPD) reduces endogenous pyrimidines and therapeutic analogues such as the anticancer agent 5-fluorouracil (5FU). Among Caucasian populations DPD activity is highly variable and subject to polymorphic regulation. To evaluate interethnic influence, DPD activity was assessed in South-west Asian, Kenyan and Ghanaian populations. METHODS: DPD activity was determined in peripheral mononuclear cells using[14C]-5-fluorouracil and h.p.l.c. analysis. RESULTS: A high degree of variation in DPD activity was observed within each population (range CV = 34-48%). Median DPD activity also varied between these populations. South-west Asian and Kenyan subjects exhibited almost identical median values (192 and 193.5 pmol min(-1) mg(-1), respectively), which were similar to Caucasians (median 215 pmol min(-1) mg(-1). A significantly lower median DPD activity (119 pmol min(-1) mg(-1)) was observed in the Ghanaian population. CONCLUSIONS: The similarity in DPD activity between Caucasian, Kenyan and South-west Asian populations suggests that the incidence of 5FU-related toxicity may be comparable in these groups. The pharmacokinetic implications of lower activity amongst Ghanaians needs to be evaluated.

Catechol O-methyltransferase (COMT) inactivates neurotransmitters, hormones and drugs such as levodopa. COMT activity is inherited in an autosomal recessive manner and individuals with low activity have thermolabile COMT protein. A low activity allele has been demonstrated at codon 108/158 of the soluble and membrane bound COMT protein, respectively, whereby a G to A transition results in a valine to methionine substitution, rendering the protein more thermolabile. As ethnic differences in erythrocyte COMT activity have been previously demonstrated, the frequency of low activity alleles were investigated in 265 British Caucasian, 99 British South-west Asian and 102 Kenyan individuals. Genotyping of COMT codon 108/158 was performed using a minisequencing method. Erythrocyte COMT activity was measured in 60 British Caucasian individuals by radiochemical assay. The frequency of low activity alleles was 0.54 in Caucasians, 0.49 in South-west Asians, and 0.32 in Kenyans. There was a much lower frequency of individuals with homozygous low activity allele in the Kenyan population (9%) than in Caucasians (31%) or South-west Asians (27%). Erythrocyte COMT activity was lower and less thermostable in individuals with homozygous low activity alleles. The data provide molecular evidence that low COMT is less common in African individuals than the Caucasian population. PMID: 9682265 [PubMed - indexed for MEDLINE]

In: Pharmacogenetics. 1999 Dec;9(6):773-6. Douglas McLean Publishing; 1999. Abstract
Thiopurine methyltransferase (TPMT) degrades 6-mercaptopurine, azathioprine and 6-thioguanine which are commonly used in the treatment of autoimmune diseases, leukaemia and organ transplantation. TPMT activity is polymorphic as a result of gene mutations. Heterozygous individuals have an increased risk of haematological toxicity after thiopurine medication, while homozygous mutant individuals suffer life threatening complications. Previous population studies have identified ethnic variations in both phenotype and genotype, but limited information is available within African populations. This study determined the frequency of common TPMT variant alleles in 101 Kenyan individuals and 199 Caucasians. The frequency of mutant alleles was similar between the Caucasian (10.1%) and Kenyan (10.9%) populations. However, all mutant alleles in the Kenyan population were TPMT*3C compared with 4.8% in Caucasians. In contrast TPMT*3A was the most common mutant allele in the Caucasian individuals. This study confirms ethnic differences in the predominant mutant TPMT allele and the findings will be useful for the development of polymerase chain reaction-based strategies to prevent toxicity with thiopurine medications.

J Immunol. 2007 Mar 15;17.". In: J Immunol. 2007 Mar 15;178(6):3750-6. John Benjamins Publishing Company; 2007. Abstract
HIV diversity may limit the breadth of vaccine coverage due to epitope sequence differences between strains. Although amino acid substitutions within CD8(+) T cell HIV epitopes can result in complete or partial abrogation of responses, this has primarily been demonstrated in effector CD8(+) T cells. In an HIV-infected Kenyan cohort, we demonstrate that the cross-reactivity of HIV epitope variants differs dramatically between overnight IFN-gamma and longer-term proliferation assays. For most epitopes, particular variants (not the index peptide) were preferred in proliferation in the absence of corresponding overnight IFN-gamma responses and in the absence of the variant in the HIV quasispecies. Most proliferating CD8(+) T cells were polyfunctional via cytokine analyses. A trend to positive correlation was observed between proliferation (but not IFN-gamma) and CD4 counts. We present findings relevant to the assessment of HIV vaccine candidates and toward a better understanding of how viral diversity is tolerated by central and effector memory CD8(+) T cells.

Department of Pharmacology and Toxicology, University of Nairobi, Kenya. The relative bioavailabilities of three carbamazepine tablet formulations available in the Kenyan market (Temporal(R), Taver(R) and Carbamazepine Lincoln) compared with the innovator formulation (Tegretol(R)) were evaluated in seven healthy African volunteers (5 males, two females; aged 22-36 years), according to a randomised fourway crossover study design, following oral administration of single 200 mg doses with a three week washout period. In vitro dissolution profiles of the tablets were also evaluated. Relative bioavailabilities ((F)rel) of Temporal(R), Taver(R) and Carbamazepine Linocoln were 101.2%, 82.2% and 71.6% respectively, compared with Tegretol(R). Percent drug content dissolved in vitro after I hour were 91.3%, 75.9% and 39.3% for Temporal(R), Taver(R) and Carbamazepine Lincoln, respectively. It was concluded that Temporal(R) was bioequivalent to Tegretol(R) while Taver(R) and Carbamazepin Lincoln were bioinequivalent to Tegretol(R). Administration of Taver(R) or Carbamazepine Lincoln might lead to poor control of epileptic seizures.

Cross-sectional analyses have demonstrated an association between use of hormonal contraceptives and shedding of herpes simplex virus (HSV). This prospective study evaluated the effect of initiating use of hormonal contraception on cervical HSV detection. Two hundred women who were seropositive for HSV-2 and human immunodeficiency virus (HIV) type 1 were examined for cervical mucosal HSV by use of quantitative DNA polymerase chain reaction before and after beginning the use of hormonal contraceptives. Cervical HSV was detected in 32 women (16.0%) before initiating and in 25 women (12.5%) after initiating use of hormonal contraception (P=.4). There were no significant differences in HSV shedding among the subgroups of women starting combination oral contraceptives containing both estrogen and progesterone or progesterone-only contraceptives. Among the 54 women who shed HSV at least once, the median change in cervical HSV after initiation of hormonal contraception was -313 copies/swab. In this prospective study, use of hormonal contraceptives did not increase detection of cervical HSV.
