As the number of fatalities from cardiovascular diseases declines in western industrial nations, an opposite trend is observed in the East African region. Inter-regional variations in the prevalence of vascular disorders have been attributed to socioeconomic, psychosocial and heritable physiological parameters. Although faulty mineralocorticoid metabolism and the dysfunctional kidney are prominent features of circulatory problems, many current studies are focused on membrane receptors, transmembrane ion transport mechanisms, ion channels and the possible genetic polymorphisms that determine the characteristics of those molecular structures in the vascular system of normal or hypertensive persons. In this review, a composite of the data available on each of the above parameters and its significance in the pathogenesis of hypertension in the industrial West and transforming economies of East Africa is presented. |

Click to View Abstract
Schrebera alata is a deciduous fuel tree from which the Samburu people in Northern Kenya obtain bark for medicinal purposes. A pharmacologically active principle that produces analgesic effects can be extracted from the bark with hot water. When administered to rats daily for a period of 6 weeks, the extract of bark (referred to as II kau kawa by the Samburu) caused reduced activities of succinic dehydrogenase, an enzyme that is involved in oxidative processes, and cholinesterase in heart and liver tissues. Histological sections from the liver revealed extensive cellular degeneration and small areas with necrotic lesions. Only that fraction of the bark extracts which contained components less soluble in alcohol produced such lesions within a 2 weeks period. The same fraction is associated with pharmacological activity. Since hepatic injuries occur frequently and the incidence of primary hepatic carcinoma is high in tropical areas, the role of natural toxins as aetiologic factors for cirrhotic conditions must be adequately clarified. It is apparent that bark from S.alata possesses some toxicity and its effects on the liver indicate it can contribute significantly to prevalent hepatocellular damages.

Click to View Abstract
Hematologic values for peripheral blood and marrow, serum proteins, B12 and folic acid levels are given for recently caught and captive baboons (P. anubis and P.sinocephalus) in Nairobi. The hemaglobin levels were higher in captive than in wild animals. There was no change in the serum proteins unless the animals were on a riboflavindeficient diet. Marrow activity as estimated by counting red cell precursors as a percentage of the total nucleated red cell population agreed with that of red cell uptake of Fe59 ferric chloride. Hemosiderin was present in the marrow in all the animals. Protein turnover studies using I131-labeled albumin with ion exchange resins indicated that the protein catabolic rate and turnover was high. This may have been due to the selective destruction of the human albumin in the baboon.
