Bedi BS, Debas HT, Wasunna AE, Buxton BF, Gillespie IE. "Secretin and cholecystokin-pancreozymin in combination in the inhibition of gastric acid secretion.". 2012. Abstract

Both secretin, and the single substance which possesses both cholecystokinin and pancreozymin activity, have been shown to inhibit gastric acid secretory responses. Since potentiation may occur between pairs of stimulants of gastric secretion, the effects of combining secretin and cholecystokinin/pancreozymin have been studied in Heidenhain pouches stimulated by continuous intravenous pentagastrin. Evidence suggesting potentiation between these two inhibitor agents is presented

Buxton B, Wasunna AE, Saunders J, Gillespie IE. "Site of the abnormal stimulus of gastric secretion after small bowel exclusion.". 2007. Abstract

In dogs with either vagally innervated or denervated pouches, the acid responses to a standard meal, a meal which bypassed the greater part of the small bowel, and a meal introduced directly into the small intestine were measured before and after exclusion of 75% of the small bowel.After intestinal exclusion an increase in acid secretion was found in the latter part of the acid response to the standard meal and the intestinal meal. No increase in acid secretion resulted from the meals which bypassed the small bowel. These findings suggest that an increase in stimulation from the remaining small intestine is responsible for the elevation in acid secretion following small bowel exclusion.

O PROFWASUNNAAGGREY. "Steel CM, Ennis M, Levin AG, Wasunna A. The mitogenic response of cryopreserved human lymphocytes in a microculture system. Cytobios. 1977;18(70):89-99.". In: Cytobios. 1977;18(70):89-99. John Benjamins Publishing Company; 1977. Abstract

Fresh blood lymphocytes from nine health donors have been compared with samples from the same donors, recovered after period of 2 to 21 months storage in liquid nitrogen, for the capacity to respond to a range of mitogens in vitro. A microculture assay was used, requireing aliquots of only 25,000 cells. The mean levels of 14C-thymidine uptake for fresh and frozen samples were closely comparable when the cells had been stimulated by PHA, Pokeweed or mitomycin-C-treated allogeneic lymphoblastoid cells. Lymphocytes from six East African donors, frozen by a very simple technique, were recovered after 3 or more years storage in liquid nitrogen. Five of the samples were in good condition as judged by cell viability and the capacity to form spontaneous 'E' rosettes with sheep erythrocytes. These five samples also responded extremely well to PHA, PWM and mitomycin-C-treated allogeneic lymphoblastoid cells using the microculture assay. This study extends the range of applications of cell banks in which small aliquots of blood lymphocytes are stored in liquid nitrogen for periods of several years.

Wasunna E. "Surgical manpower in Africa.". 1987. Abstract

There is a marked shortage of surgical manpower all over Africa. General surgeons undertake a very wide range of surgical work because of the lack of specialists. Orthopaedic and general surgeons both care for accident injuries. Current training and recruitment programs are inadequate in correcting existing gross manpower deficiencies. The situation is further aggravated by a gross maldistribution of available manpower in favor of large urban centers. In many parts of rural Africa, minor surgical procedures are carried out by suitably trained, non-physician health workers, but facilities and resources for surgery outside urban centers are generally inadequate. The World Health Organization program on essential surgical and anesthetic procedures, which is currently under way in collaboration with the International Federation of Surgical Colleges, the World Federation of Societies of Anesthesiologists, and other professional bodies, should have a significant impact on these urgent needs for basic surgery in rural district hospitals
