Abstract:

Yaji is a complex mixture of groundnut cake powder, additives, spices and salt. The production and consumption of Yaji is not regulated despite the potential health hazards of its numerous active principles. This fact has been the basis for several scientific investigations aimed at determining the effect of Yaji on body organs. The present histological study is intended to determ ine the effects of Yaji consumption on the blood supply of the brain. Eighteen weeks old white albino rats of an average weight of 170g were used for this study. They were divided into eight groups (A H) of three subgroups each. Subgroup 1, 2 and 3 represents experimental periods of 2 weeks, 4weeks, and 6 weeks respectively. Group A rats served as control and were fed with normal feed (growers mash) only, while Groups B H served as the test groups and were fed with normal feed plus graded levels of Yaji (B, 10%; C, 20%; D, 30%; E, 40%; F, 50%; G, 60%; and H, 70%). At the end of the respective experimental periods, test group rats were sacrificed in order to harvest the brain tissues for tissue processing. The stained brain tissue micrographs showed vascular changes (fat embolism and thrombosis) and cerebral infarction in the brain of test rats in group B2 (4weeks; 10%), B3 (6weeks; 10%) and F3 (6 weeks; 50%). Our findings suggest that at sustained high dose consumption, Yaji has the capacity to induce cerebrovascular changes with its attendant consequences such as hypoxia ischaemia and subsequently, brain tissue necrosis.
