The present studies were designed and carried out to determine if hydrogen peroxide (H2O2) is involved in the regulation of erythropoietin (Epo) gene expression and stimulation of Epo production in the hepatocellular (Hep 3B) cells. Hep 3B cells were incubated with varying concentrations of H2O2 for periods of 6 hours or 24 hours. In other experiments Hep 3B cells were incubated for 24 hours with or without increasing concentrations of catalase and in the presence of H2O2. Culture medium levels of Epo were determined and quantitation of Epo mRNA was also made. The results indicate that H2O2 increases the levels of Epo mRNA and Epo hormone production in Hep 3B cells, and that catalase, the specific scavenger of hydrogen peroxide, inhibits Epo production in these cells. Based on these findings, it is concluded that H2O2 takes part in the signal transduction mechanisms in Epo production. It is recommended that further studies be undertaken to find out the source of the hydrogen peroxide in the hepatocellular carcinoma cells.

Analysis of 355 cases with fractures of the mandible indicated that 74.9% of the cases were due to interpersonal violence and 13.8% were caused by road traffic accidents. The men to women ratio was 8.4:1 and 75.5% of the fracture cases had single fractures while 24.5% had multiple fractures. In cases with a single fracture, the most commonly involved mandibular site was the body (42.2%). The angle of mandible was most frequently fractured (50.5%) in cases with multiple fractures.

The serum antibody response in golden hamsters (Mesocricetus auratus) infected with the intestinal trematode Echinostoma caproni was examined with ELISA, SDS-PAGE and Western blot, and IFAT techniques. All methods showed that the hamsters responded slowly but developed a clear positive humoral response to the infection. In most hamsters, an antibody response to infection could not be detected earlier than 11-13 weeks after infection with 6 or 25 metacercariae, and responses were weak when compared to previous results from mice infected with the same parasite. IFAT with positive hamster sera on live juvenile E. caproni showed only fluorescence at the posterior tip, which is a different pattern from that seen using from infected mice, indicating a different response to antigens on the juvenile parasites by these two hosts. The results are discussed in relation to the limited selfcure and development of resistance which is observed in golden hamsters infected with E. caproni.

This paper reports the detailed results of a study of the impact of the Health Workers for Change (HWFC) workshop series on clients' perceptions of health services, relationships within the health centre and relations between the health facility and the district health system. The study was carried out in three stages: baseline, intervention and evaluation over a period of 20 months. Data, both qualitative and quantitative, were collected at three levels: client, facility and system. Results indicate that relations between health workers and clients improved a great deal after the intervention while those between the facility and the system remained to a large extent unchanged. The paper concludes that, with external support and help, especially from the health system level, health workers can work towards improving health services and their job satisfaction, which can lead to better health worker-client relations.

Asiatic acid (AA) is a pentacyclic triterpene found in Centella asiatica. In the present study, the mechanism of anticancer effect of AA on skin cancer was investigated. AA decreased viability and induced apoptosis in human melanoma SK-MEL-2 cells in a time- and dose-dependent manner. AA also markedly increased intracellular reactive oxygen species (ROS) level and enhanced the expression of Bax but not Bcl-2 protein in the cells. In addition, AA-induced activation of caspase-3 activity in a dose-dependent manner. Pretreatment with Trolox, an antioxidant, significantly blocked the induction of Bax and activation of caspase-3 in AA-treated cells. Furthermore, Ac-DEVD-CHO, a specific caspase-3 inhibitor, and Trolox prevented the AA-induced apoptosis. AA did not elevate p53 nuclear protein levels that are present in a mutant form in SK-MEL-2 cells. These results suggest that AA-induced apoptosis may be mediated through generation of ROS, alteration of Bax/Bcl-2 ratio and activation of caspase-3, but p53-independent. These results further suggest that AA may be a good candidate for the therapeutic intervention of human skin cancer.

Recent publications have demonstrated that the protease caspase-1 is responsible for the processing of pro-interleukin 18 (IL-18) into the active form. Studies on cell lines and murine macrophages have shown that the bacterial invasion factor SipB activates caspase-1, triggering cell death. Thus, we investigated the role of SipB in the activation and release of IL-18 in human alveolar macrophages (AM), which are the first line of defense against inhaled pathogens. Under steady-state conditions, AM are a more important source of IL-18 than are dendritic cells (DC) and monocytes. Cytokine production by AM and DC was compared after both types of cells had been infected with a virulent strain of Salmonella enterica serovar Typhimurium and an isogenic sipB mutant, which were used as an infection model. Infection with virulent Salmonella led to marked cell death with features of apoptosis while both intracellular activation and release of IL-18 were demonstrated. In contrast, the sipB mutant did not induce such cell death or the release of active IL-18. The specific caspase-1 inhibitor Ac-YVAD-CMK blocked the early IL-18 release in AM infected with the virulent strain. However, the type of Salmonella infection did not differentially regulate IL-18 gene expression. We concluded that the bacterial virulence factor SipB plays an essential posttranslational role in the intracellular activation of IL-18 and the release of the cytokine in human AM.

Aminoglutethimide (AG) 500 mg was administered orally to four normal volunteers and eight patients undergoing treatment for metastatic breast cancer. In each subject the acetylator phenotype was established from the monoacetyldapsone (MADDS)/dapsone (DDS) ratio. Acetylaminoglutethimide (acetylAG) rapidly appeared in the plasma and its disposition paralleled that of AG. A close relationship (P less than 0.01) was observed between the acetyl AG/AG and MADDS/DDS ratio suggesting that AG may undergo polymorphic acetylation like DDS. AG half-life was 19.5 +/- 7.7 h in seven fast acetylators of DDS and 12.6 +/- 2.3 h in five slow acetylators and its apparent metabolic clearance was significantly (P less than 0.01) related to the acetylAG/AG ratio. Over 48 h the fast acetylators excreted 7.7 +/- 4.4% of the administered AG dose in the urine as unchanged AG as compared to 12.4 +/- 2.8% in slow acetylators. A much smaller fraction of the dose was excreted as acetylAG: 3.6 +/- 1.5% by fast and 1.9 +/- 1.0% by slow acetylators respectively. After 7 days treatment with AG at an accepted clinical dose regimen to the eight patients there were significant reductions in the half-lives of AG (P less than 0.01) and acetylAG (P less than 0.01) and a trend (0.1 greater than P greater than 0.05) towards reduction of the acetylAG/AG ratio which became significant (P less than 0.05) if the one patient on a known enzyme inducer was omitted. The mean apparent volume of distribution was not significantly (P greater than 0.1) altered but the mean apparent systemic clearance of AG was increased (P less than 0.05). These changes are attributed to auto-induction of oxidative enzymes involved in AG metabolism.

Abstract: The present study was carried out to compare the use of liver and plasma analysis as methods of assessing the status of cobalt, zinc and selenium in sheep, and also to assess the anthelmintic efficacy of fortified and non-fortified albendazole preparations. plasma and liver samples were collected in duplicate from fourteen sheep aged nine to twelve months. Plasma samples were collected on days 0, 7, 14, 21 and 28 and liver samples  on days 0, 14 and 28 post treatment, upon sacrifice of the study animals. Various trace elements were isolated from the organic matrix by wet oxidation for mineral analysis using atomic absorption spectrophotometry. data was statistically analysed using repeated measurement test. Significance was noted at p < 0.05. Both the fortified albendazole and non fortified albendazole cleared all the worms in the treated sheep by day 14 post treatment. All the trace elements were shown to be more bioavailable in the liver and plasma of fortified albendazole (Group B) treated sheep compared to the non-fortified albendazole (Group A) treated sheep. The current study has shown that the liver is a better indicator of cobalt, zinc and selenium status in sheep compared to plasma. Key words: Plasma; Liver; Cobalt; Zinc and Selenium

Epidemiological study of osteogenic sarcoma variations in incidence between Ethnic groups and Geographical Regions 1966-1979.International Orthopaedics Sicot.". In: International Orthopaedics Sicot. University of Nairobi.; Submitted. Abstract
Kenya is a country of marked environmental and ethnic diversity. A study of osteogenic sarcoma occurring in Kenya from 1968 to 1978 revealed 251 cases, representing between 89% and 100% of the predicted number. Variations in age, sex and anatomical location were within classical limits. However, the incidence of osteogenic sarcoma amongst the Central Bantu was significantly higher than predicted (P less than 0.0001), whilst the incidence among the Western Bantu was significantly lower (P less than 0.002), despite their similar ethnic origins. Two geographically dissimilar areas likewise exhibited significant differences in incidence. The Eastern province showed a higher incidence (P less than 0.02), whereas the Nyanza Province (P less than 0.001) and the adjacent Western Province (P less than 0.005) showed a lower than predicted incidence. These observations suggest that in Kenya a geomedical variable affects the incidence of osteogenic sarcoma and that genetic variation has no effect on incidence.

In contrast with mammalian cells, little is known about the control of Ca2+ entry into primitive protozoans. Here we report that Ca2+ influx in pathogenic Trypanosoma brucei can be regulated by phospholipase A2 (PLA2) and the subsequent release of arachidonic acid (AA). Several PLA2 inhibitors blocked Ca2+ entry; 3-(4-octadecyl)-benzoylacrylic acid (OBAA; IC50 0.4+/-0.1 microM) was the most potent. We identified in live trypanosomes PLA2 activity that was sensitive to OBAA and could be stimulated by Ca2+, suggesting the presence of positive feedback control. The cell-associated PLA2 activity was able to release [14C]AA from labelled phospholipid substrates. Exogenous AA (5-50 microM) also initiated Ca2+ entry in a manner that was inhibited by the Ca2+ antagonist La3+ (100 microM). Ca2+ entry did not depend on AA metabolism or protein kinase activation. The cell response was specific for AA, and fatty acids with greater saturation than tetraeicosanoic acid (AA) or with chain lengths less than C20 exhibited greatly diminished ability to initiate Ca2+ influx. Myristate and palmitate inhibited PLA2 activity and also inhibited Ca2+ influx. Overall, these results demonstrate that Ca2+ entry into T. brucei can result from phospholipid hydrolysis and the release of eicosanoic acids.

 Background: Increasing access to HIV-related health care is very important in access resource limited countries. In Kenya HIV prevalence increased in 2008 to 7.8 from 6.7 in 2003. Women are mostly affected with infection rates 2-3 times more than men. Challenges women face attempting to access HIV care is urgent.Purpose: Study sought to identify health needs of HIV infected women in Kenya grapple with.Method: Forty Urban (Nairobi) and rural (Eastern Province) infected women participated in the study. A cross sectional qualitative narrative study eilicited life stories of health needs. Unstructured in-depth interviews,tape recorded, transcribed and translated to English. Data analysis used N-vivo qualitative analysis soft ware. Multistage narrative analysis was used to explore emergent themes.Findings: Women of mean age 37 years and 3 years since diagnosis described prolonged illnesses sufferred by spouses, themselves and children burdened by inadequate HIV care.Conclusion: Early diagnosis and treatment Interventions are necessary for wellbeing and long life.

In contrast with mammalian cells, little is known about the control of Ca2+ entry into primitive protozoans. Here we report that Ca2+ influx in pathogenic Trypanosoma brucei can be regulated by phospholipase A2 (PLA2) and the subsequent release of arachidonic acid (AA). Several PLA2 inhibitors blocked Ca2+ entry; 3-(4-octadecyl)-benzoylacrylic acid (OBAA; IC50 0.4+/-0.1 microM) was the most potent. We identified in live trypanosomes PLA2 activity that was sensitive to OBAA and could be stimulated by Ca2+, suggesting the presence of positive feedback control. The cell-associated PLA2 activity was able to release [14C]AA from labelled phospholipid substrates. Exogenous AA (5-50 microM) also initiated Ca2+ entry in a manner that was inhibited by the Ca2+ antagonist La3+ (100 microM). Ca2+ entry did not depend on AA metabolism or protein kinase activation. The cell response was specific for AA, and fatty acids with greater saturation than tetraeicosanoic acid (AA) or with chain lengths less than C20 exhibited greatly diminished ability to initiate Ca2+ influx. Myristate and palmitate inhibited PLA2 activity and also inhibited Ca2+ influx. Overall, these results demonstrate that Ca2+ entry into T. brucei can result from phospholipid hydrolysis and the release of eicosanoic acids.

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]

The area was known to have a domestic-dog rabies but the involvement of wildlife was unknown. Four sublocations within a transect of approximately 20 km along the Nairobi-Mombasa highway were selected as the study area. A total of 202 households within the area were randomly selected and visited to collect information on wildlife abundance and habits, and for wild-life-domestic dog interactions. Forty of the 202 households were randomly selected for wildlife trapping. An eight-month long community-and road-kill-based rabies surveillance was implemented in the 4 sublocations. The white-tailed mongoose (Ischeumia albicauda), the genet cat (Genetta genetta), the common mongoose (Herpestes spp), the civet cat (Viverra civetta) and the bush squirrel (Paraxerus spp), were identified as the most prevalent species of wildlife in the area. Seventy-one percent (143/202) of the households reported having heard or witnessed their dogs fighting with unspecified wild animal species. White-tailed mongooses (11) and genet cats (11) were the species of wild carnivores trapped within the precincts of the households. The domestic dog accounted for 91% (20/22) of the rabies positive animal brain specimens collected in the community-based rabies surveillance. Only 6.2% (5/81) of the specimens from road-kills were positive for rabies including a domestic cat, a goat, a common mongoose (Herpestes spp), a genet cat, and an unidentified wildlife species.   This study has revealed that small wild carnivores are frequent in Kibwezi and interact with dogs. Dogs are currently the main species for transmission of rabies but there is some rabies in wildlife. The potential for wildlife to act as a reservoir for rabies as in other areas where dog rabies has been controlled needs further investigation.   Keywords: Rabies; Surveillance; Community-based; road-kills; Kenya

Neurological impairment is common in resource-poor countries, but its causes are not clear. Computerized tomography (CT) of the brain has been used to determine the cause of brain insults that may manifest as neurological impairments. The authors conducted a community survey in Kilifi of 10 218 children aged 6 to 9 years to detect neurological impairment. From this survey, 34 children were identified, of whom 16 had motor deficits, 11 complex partial seizures, 4 microcephaly or macrocephaly, and 3 severe developmental delay. These children were assessed with elicitation of history, physical examination, and CT scan of the brain. Sixteen (47%) of the scans showed abnormalities: cerebral atrophy (n = 9), schizencephaly (n = 3), periventricular leukomalacia (n = 2), porencephalic cyst (n = 1), and agenesis of the corpus callosum (n = 1). The minimum prevalence of abnormalities on the CT scan of the brain is 1.56 of 1000, and the prevalence of schizencephaly is 0.29 of 1000. Motor impairments were more likely to show abnormality than the other indications. CT abnormalities are common in children with neurological impairment in Kenya, but the appearances did not identify a major cause.

Kenya is a country of marked environmental and ethnic diversity. A study of osteogenic sarcoma occurring in Kenya from 1968 to 1978 revealed 251 cases, representing between 89% and 100% of the predicted number. Variations in age, sex and anatomical location were within classical limits. However, the incidence of osteogenic sarcoma amongst the Central Bantu was significantly higher than predicted (P less than 0.0001), whilst the incidence among the Western Bantu was significantly lower (P less than 0.002), despite their similar ethnic origins. Two geographically dissimilar areas likewise exhibited significant differences in incidence. The Eastern province showed a higher incidence (P less than 0.02), whereas the Nyanza Province (P less than 0.001) and the adjacent Western Province (P less than 0.005) showed a lower than predicted incidence. These observations suggest that in Kenya a geomedical variable affects the incidence of osteogenic sarcoma and that genetic variation has no effect on incidence.

This study determined the prey base for four main carnivores found in Samburu Community group ranches and grazing area, Lion (Panthera leo), Leopard (Panthera pardus), Wild dog (Lycaon pictus) and Hyaena (Crocuta crocuta, and Hyaena hyaena). A total of 96 scat samples including, 8 from Lion, 16 Leopards', 2 Wild dogs', and 70 Hyaenas' were collected, identified and microscopically analyzed for prey hair characterisation. At least 50 different hairs from every scat sample were mounted on slides and microscopically characterized using details from reference hairs. Hairs from 18 depredated species both domestic and wild ungulates were recovered from the scat samples. Predated species were identified, as either domestic (Cow, Sheep, Goat, Donkey, and Camel) or wild ungulate prey (Grant's gazelle, plain zebra, Grevy's Zebra, Impala, Waterbuck, Dikdik, Eland, lesser Kudu, greater Kudu, Baboon, rock Hyraxes, Elephant and Oryx). The carnivores showed a relatively high kill of wild ungulate prey compared to domestic prey. Camel was the most preferred cow and donkey respectively. Grevy's zebra contributed highest to the lion's diet while the Plain zebra was most preferred by the leopard. Both the hyaena and Wild dog had a preference for the waterbuck. The Hyaena had the highest domestic depredation, while all the other big cats depredated more on wild ungulates.

Malaria is a major public health problem that is presently complicated by the development of resistance by Plasmodium falciparum to the mainstay drugs. Thus, new drugs with unique structures and mechanism of action are required to treat drug-resistant strains of malaria. Historically, compounds containing a novel structure from natural origin represent a major source for the discovery and development of new drugs for several diseases. This paper presents ethnophytotherapeutic remedies, ethnodiagnostic skills, and related traditional knowledge utilized by the Digo community of the Kenyan Coast to diagnose malaria as a lead to traditional bioprospecting. The current study was carried out in three Digo villages of Diani sub-location between May 2009 and December 2009. Data was collected using semi-structured interviews, and open and close-ended questionnaires. A total of 60 respondents (34 men and 26 women) provided the targeted information. The results show that the indigenous knowledge of Digo community on malaria encompasses not only the symptoms of malaria but also the factors that are responsible for causing malaria, attributes favoring the breeding of mosquitoes and practices employed to guard against mosquito bites or to protect households against malaria. This knowledge is closely in harmony with scientific approaches to the treatment and control of the disease. The Digo community uses 60 medicinal plants distributed in 52 genera and 27 families to treat malaria. The most frequently mentioned symptoms were fever, joint pains, and vomiting while the most frequently mentioned practices employed to guard against mosquito bites and/or to protect households against malaria was burning of herbal plants such as Ocimum suave and ingestion of herbal decoctions and concoctions. The Digo community has abundant ethnodiagnostic skills for malaria which forms the basis of their traditional bioprospecting techniques. Keywords: malaria, antimalarials, ethnopharmacology, ethnodiagnostic skills, Digo community, bioprospecting

Kenya is a country of marked environmental and ethnic diversity. A study of osteogenic sarcoma occurring in Kenya from 1968 to 1978 revealed 251 cases, representing between 89% and 100% of the predicted number. Variations in age, sex and anatomical location were within classical limits. However, the incidence of osteogenic sarcoma amongst the Central Bantu was significantly higher than predicted (P less than 0.0001), whilst the incidence among the Western Bantu was significantly lower (P less than 0.002), despite their similar ethnic origins. Two geographically dissimilar areas likewise exhibited significant differences in incidence. The Eastern province showed a higher incidence (P less than 0.02), whereas the Nyanza Province (P less than 0.001) and the adjacent Western Province (P less than 0.005) showed a lower than predicted incidence. These observations suggest that in Kenya a geomedical variable affects the incidence of osteogenic sarcoma and that genetic variation has no effect on incidence.

The present studies were designed and carried out to determine if hydrogen peroxide (H2O2) is involved in the regulation of erythropoietin (Epo) gene expression and stimulation of Epo production in the hepatocellular (Hep 3B) cells. Hep 3B cells were incubated with varying concentrations of H2O2 for periods of 6 hours or 24 hours. In other experiments Hep 3B cells were incubated for 24 hours with or without increasing concentrations of catalase and in the presence of H2O2. Culture medium levels of Epo were determined and quantitation of Epo mRNA was also made. The results indicate that H2O2 increases the levels of Epo mRNA and Epo hormone production in Hep 3B cells, and that catalase, the specific scavenger of hydrogen peroxide, inhibits Epo production in these cells. Based on these findings, it is concluded that H2O2 takes part in the signal transduction mechanisms in Epo production. It is recommended that further studies be undertaken to find out the source of the hydrogen peroxide in the hepatocellular carcinoma cells.

Towers are typical structures that can be found in many urban and rural landscapes the world over. From their basic design, they are usually exposed to severe environmental loads. It is therefore prudent to carry out periodic maintenance that includes checking that they are correctly aligned. This paper describes a method that was used for the re-alignment of a guyed tower in Limuru, Kenya. Angular and distance observations, made from two observation points detected a vertical misalignment that was larger than the acceptable tolerance of l/400. An iterative re-alignment procedure was then applied, resulting in an acceptable final misalignment of 1 / 520.

This paper reports the detailed results of a study of the impact of the Health Workers for Change (HWFC) workshop series on clients' perceptions of health services, relationships within the health centre and relations between the health facility and the district health system. The study was carried out in three stages: baseline, intervention and evaluation over a period of 20 months. Data, both qualitative and quantitative, were collected at three levels: client, facility and system. Results indicate that relations between health workers and clients improved a great deal after the intervention while those between the facility and the system remained to a large extent unchanged. The paper concludes that, with external support and help, especially from the health system level, health workers can work towards improving health services and their job satisfaction, which can lead to better health worker-client relations.

Cities around the world are currently facing considerable pressure to cope with infrastructure provision amidst rapid urban development and economic growth. Kenya is also facing an increasing growth of informal settlements in her urban centres. As rapid urbanization takes its toll, so has the development and growth of slums. More than 34% of Kenya‟s total population lives in urban areas and of this, more than 71% is confined in informal settlements (UN-Habitat, 2009). This paper presents the result of study to assess the effects of the change in land use in two sub-catchments, in an urban area close to the Nairobi Central Business District (NCBD). The paper compares the change in land use of two regions in Nairobi, Kenya that are slowly changing due to the fast growing population and economy, on urban runoff.

JOHN DRYABS. "Insurance Problems of P.T.A. Trade.". In: An Article in the Underwriter Journal. SITE; Submitted. Abstract

This paper describes the methodology and presents preliminary results of an economic appraisal of a community based health care project in Kenya. Community health workers, trained for 12 weeks and deployed in two locations in Kenya's Western Province, act as first contact providers of basic health care and promoters of selected health, sanitation and nutrition practices. A Cost Benefit Analysis has been undertaken using the Willingness to Pay approach to compare the costs of the project and its benefits. The benefits are in the form of more easily accessible basic health care and are measured as consumer surplus accruing to the community. Gain in consumer surplus is consequent on the fall of average user costs and rise in utilisation of the project established points of first contact with primary health care. The argument for the economic viability of the project is validated by the large Net Present Value and Benefit Cost Ratio obtained for the whole of the project area and for the two locations separately. Although the evaluation technique used faces the problem of valuation of community time, aggregation of health care services at all points of first contact and the partial nature of cost benefit analysis evaluations, the results are strongly in favour of decentralisation of primary health care on similar lines in the rest of the country.

When it comes to coverage service, however, user satisfaction can be considered the logical metric of performance. This study presents a hybrid Quality of Experience (QoE) index that can be used as a basis of network coverage planning efficiency assessment. A spatial analysis framework is employed to evaluate the user perceived QoS offered by one of the leading cellular service providers in Kenya as perceived by consumers under everyday conditions of use. Regions where subscribers may be experiencing low service quality service were identified. The study shows that urban based consumers tend to have higher quality expectations than the rural users.

In contrast with mammalian cells, little is known about the control of Ca2+ entry into primitive protozoans. Here we report that Ca2+ influx in pathogenic Trypanosoma brucei can be regulated by phospholipase A2 (PLA2) and the subsequent release of arachidonic acid (AA). Several PLA2 inhibitors blocked Ca2+ entry; 3-(4-octadecyl)-benzoylacrylic acid (OBAA; IC50 0.4+/-0.1 microM) was the most potent. We identified in live trypanosomes PLA2 activity that was sensitive to OBAA and could be stimulated by Ca2+, suggesting the presence of positive feedback control. The cell-associated PLA2 activity was able to release [14C]AA from labelled phospholipid substrates. Exogenous AA (5-50 microM) also initiated Ca2+ entry in a manner that was inhibited by the Ca2+ antagonist La3+ (100 microM). Ca2+ entry did not depend on AA metabolism or protein kinase activation. The cell response was specific for AA, and fatty acids with greater saturation than tetraeicosanoic acid (AA) or with chain lengths less than C20 exhibited greatly diminished ability to initiate Ca2+ influx. Myristate and palmitate inhibited PLA2 activity and also inhibited Ca2+ influx. Overall, these results demonstrate that Ca2+ entry into T. brucei can result from phospholipid hydrolysis and the release of eicosanoic acids.

Asiatic acid (AA) is a pentacyclic triterpene found in Centella asiatica. In the present study, the mechanism of anticancer effect of AA on skin cancer was investigated. AA decreased viability and induced apoptosis in human melanoma SK-MEL-2 cells in a time- and dose-dependent manner. AA also markedly increased intracellular reactive oxygen species (ROS) level and enhanced the expression of Bax but not Bcl-2 protein in the cells. In addition, AA-induced activation of caspase-3 activity in a dose-dependent manner. Pretreatment with Trolox, an antioxidant, significantly blocked the induction of Bax and activation of caspase-3 in AA-treated cells. Furthermore, Ac-DEVD-CHO, a specific caspase-3 inhibitor, and Trolox prevented the AA-induced apoptosis. AA did not elevate p53 nuclear protein levels that are present in a mutant form in SK-MEL-2 cells. These results suggest that AA-induced apoptosis may be mediated through generation of ROS, alteration of Bax/Bcl-2 ratio and activation of caspase-3, but p53-independent. These results further suggest that AA may be a good candidate for the therapeutic intervention of human skin cancer.

Endomyocardial biopsies were performed in 11 African women in Nairobi who presented with the clinical features of peripartum cardiomyopathy. The samples were studied by light and electron microscopy. In five patients there was evidence of a "healing myocarditis", that is the presence of a mild inflammatory cell infiltration within the myocardium with foci of necrosis and variable amounts of hypertrophy and fibrosis. Of the nine patients who were followed up, three out of four with myocarditis had persistent heart failure and four out of five without myocarditis improved. Peripheral blood T lymphocyte cell subsets were measured in nine patients by means of monoclonal antibodies. A high helper:suppressor T cell ratio was found in three patients. Almost half of this group of patients with peripartum cardiomyopathy had myocarditis in their biopsy specimens. The myocarditis may have been due to an inappropriate immunological reaction in some patients.

Aminoglutethimide (AG) 500 mg was administered orally to four normal volunteers and eight patients undergoing treatment for metastatic breast cancer. In each subject the acetylator phenotype was established from the monoacetyldapsone (MADDS)/dapsone (DDS) ratio. Acetylaminoglutethimide (acetylAG) rapidly appeared in the plasma and its disposition paralleled that of AG. A close relationship (P less than 0.01) was observed between the acetyl AG/AG and MADDS/DDS ratio suggesting that AG may undergo polymorphic acetylation like DDS. AG half-life was 19.5 +/- 7.7 h in seven fast acetylators of DDS and 12.6 +/- 2.3 h in five slow acetylators and its apparent metabolic clearance was significantly (P less than 0.01) related to the acetylAG/AG ratio. Over 48 h the fast acetylators excreted 7.7 +/- 4.4% of the administered AG dose in the urine as unchanged AG as compared to 12.4 +/- 2.8% in slow acetylators. A much smaller fraction of the dose was excreted as acetylAG: 3.6 +/- 1.5% by fast and 1.9 +/- 1.0% by slow acetylators respectively. After 7 days treatment with AG at an accepted clinical dose regimen to the eight patients there were significant reductions in the half-lives of AG (P less than 0.01) and acetylAG (P less than 0.01) and a trend (0.1 greater than P greater than 0.05) towards reduction of the acetylAG/AG ratio which became significant (P less than 0.05) if the one patient on a known enzyme inducer was omitted. The mean apparent volume of distribution was not significantly (P greater than 0.1) altered but the mean apparent systemic clearance of AG was increased (P less than 0.05). These changes are attributed to auto-induction of oxidative enzymes involved in AG metabolism.

Abstract Objectives: To evaluate after 2 years, the survival rate of glass ionomer cement (GIC) sealants placed in primary molars of 6-8 year-olds and as part of proximal ART restoration. Study design: A longitudinal clinical study. Setting: Matungulu/Kangundo rural divisions, Machakos district. Participants: A total of 804 six to eight year-olds from rural Kenya received sealants as part of proximal restorations placed in primary molars using the atraumatic restorative treatment (ART) approach. Trained operators, using the ART approach, placed the proximal restorations and the sealants using Fuji IX, Ketac Molar Easymix and Ketac Molar Aplicap, together with rubber dam and cotton roll tooth-isolation methods. Evaluation to determine the survival of the sealants was done soon after placement (within 2 hours of placing them) and after 2 years. The data were analyzed using SPSS 14.0 computer programme, and the survival results related to the materials and the isolation-methods used. Results: The 2-year cumulative survival of the sealants was 10.9%, and the survival of the sealants was not significantly affected by the GIC material brand and the tooth-isolation method used. However, slightly more sealants survived when Fuji IX and rubber dam tooth-isolation method were used. Conclusion: The two-year survival rate of the sealants was poor and was not significantly influenced by the GIC material or the tooth-isolation method used.

OBJECTIVE: To determine the dental caries experience and knowledge on the causes and preventive measures for dental diseases. DESIGN: A community based cross-sectional descriptive study. SETTING: Elwak sub-district hospital, North Eastern Province, Kenya. SUBJECTS: One hundred and forty one adults who presented themselves during a dental check up at a sub-district hospital and gave written consent. MAIN OUTCOME MEASURES: Dental caries status and knowledge on its causes and preventive measures. The importance of outreach programmes in obtaining information as well as helping to alleviate the pain and suffering caused by dental diseases among communities living in remote areas is also revealed. RESULTS: Of the one hundred and forty one individuals, who were included in the study, 63.1% were women and 36.9% were men. Their ages ranged between 18 and over 65 years. 41.1% were in the 18-24-year age bracket. Regarding the oral health knowledge, 43% did not know any causes of dental diseases while 36%, 17% and 12% knew that diet, "dirt" on teeth and bacteria were possible causes, respectively. Fifty percent did not know any preventive measures for dental diseases while the rest indicated abstention from the consumption of sugary foods; and only 0.8% mentioned use of fluoridated toothpaste as a preventive measure for dental caries. 56.7% of the subjects were caries free. The mean DMFT for all ages was 3.4. Of those with caries 72.1% were women. CONCLUSION: There is a low level of oral health awareness and a moderately high level of dental caries experience in this community with women apparently carrying the biggest burden of dental caries.

The men to women ratio was 8.4:1 and 75.5% of the fracture cases had single fractures while 24.5% had multiple fractures. In cases with a single fracture, the most commonly involved mandibular site was the body (42.2%). The angle of mandible was most frequently fractured (50.5%) in cases with multiple fractures.

PIP: Menstrual blood loss (MBL) was evaluated in 74 nulliporous Kenyan women aged between 20 and 27 years. The hemoglobin levels were all in normal range with the mean of 13.65 +or- 0.8, 13.84 +or- 1.2 and 13.04 +or- 1.2 g/100 ml respectively in 3 populations. The MBL was comparable in the 3 populations with the mean of 35.1 +or- 12.6, 30.6 +or- 8.7 and 32.2 +or- 9.4 ml respectively. There was no difference of statistical significance between the 2 periods studied per each individual. This study objectively assesses the menstrual blood loss in 3 population groups–2 urban and 1 rural. The data can be used to evaluate menstrual blood loss before and after initiation of various contraceptives used in Kenya. Subjects were volunteers who were not on any contraception except barrier or natural rhythm methods, not under psychological stress and who exhibited normal physical female characteristics on examination. Those who wished to drop out, became pregnant or desired contraception, were excluded. The study confirms the individual constancy of the menstrual blood loss in this population. This has important practical implications since a single determination of the menstrual blood loss may be a fairly good expression for the average blood loss in a woman. The immediate effect of various treatments such as IUD insertion or oral contraceptives on the MBL may easily be evaluated quantitatively by measurements in consecutive periods using only 1 period as a control. The quick method can be easily used in evaluating pathological conditions e.g. iron-deficiency due to heavy bleeding, IUD-associated hemorrhage, menorrhagia and uterine fibroid.

Quality of health education during STD case management in Nairobi was assessed in 142 healthcare facilities, through interviews of 165 providers, observation of 441 STD patients managed by these providers, and 165 visits of simulated patients. For observations, scores were high for education on contact treatment (74-80%) and compliance (83%), but unsatisfactory for counselling (52%) and condom promotion (20-41%). The World Health Organization (WHO) indicator for STD case management Prevention Indicator 7 (PI7) (condom promotion plus contact treatment) was poor (38%). Public clinics strengthened for STD care generally performed best, whereas pharmacies and mission clinics performed worst. Compared with observations, scores were higher during interviews and lower during simulated patient visits, indicating that knowledge was not fully translated into practice. Interventions to improve the presently unsatisfactory service quality would be wide distribution of health education materials, ongoing training and supervision of providers, implementation of STD management checklists, and the introduction of pre-packaged kits for STD management.

Consequently, various studies regarding the impact of biotic factors on the macrophytes have been advanced but related studies on environmental parameters have lagged behind. In an attempt to address this gap, sampling on floating species and submergents was carried out in eight sampling sites in 2003 to investigate how they were influenced by a set of environmental factors. Soil texture (sandy sediments; P < 0.05, regression coefficient = - 0.749) and wind were the most important environmental parameters influencing the distribution and abundance of floating macrophytes. Combination of soil texture and lake-bed slope explained the most (86.3%) variation encountered in the submergents. Continuous translocation of the floating dominant water hyacinth to the western parts by wind has led to displacement of the submergents from those areas. In view of these findings, the maintenance and preservation of the steep Crescent Lake basin whose substratum is dominated by sand thus hosting most submergents remain important, if the whole functional purpose of the macrophytes is to be sustained.

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]

The treatments were arranged in  randomized complete block design (RCBD) with four replications. In each season, the number of aphids in five randomly  selected plants per treatment was recordced in situ. Virus symptoms (i.ncidence) were scored and expressed as a percentage  to the total plant population per plot. Forty-five days after emergence, 10 plants each from guard rows and inner rows were  randomly selected and serologically assayed for Potato Virus Y (PVY) and Potato Leaf Roll Virus (PLRV) using DAS ELISA test. Results showd that three aphid species Aphis gossypii (Glover), Macrosiphum euphorbiae (Thomas) and Myzus persicae (Sulzer) colonized on the variety with A. gossypii being the most dominant while M. persicae was least.  Higher aphid population coincided with the short rains experienced in one of the seasons. Synthetic insecticides (Bifethrin  and dimethoate) were the most effective among the treatments in reducing aphid infestation while the neem extract and mineral oil (DC- Tron) had no significant (P<0.05) difference. However, mineral-oil treated plots recorded the lowest PVY  incidence while bifenthrin-Ireated plots had the lowest PLRV incidence. It is suggested that a combination of synthetic  insecticides and mineral oil could playa major role in reduction of the aphids and their associated vectors.
