Abstract
Ninety Wistar male rats were used to study the effects of vitamin # and Se supplementation to diets containing aflatoxin B1 on the contents of liver lipids and various blood parameters. Two levels of dietary aflatoxin(0 and 1 ppm), 3 levels of vitamin E(30, 60 and 120 IU/kg), and 3 levels of Se(0.1, 1 and 2 ppm) were used to design a 2 횞 3 횞 3 factorial experiment. Rats, weighing about 200 g, were randomly allotted to 18 cages, 5 rats per cage. The aflatoxin significantly(p<.05) decreased growth rate, feed intake and feed efficiency. Aflatoxin increased the glucose level and decreased the cholesterol level in blood significantly. Levels of blood triglyceride, total protein, and albumin were not affected by aflatoxin, vitamin E or Se. Activities of blood alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were significantly increased by aflatoxin; however, the glutathione peroxidase(GSH-Px) activity in the blood was decreased by aflatoxin even in the presence of Se. The vitamin E supplementation decreased the AST activity significantly, while GSH-Px activity increased significantly as the levels of dietary Se increased. The levels of total cholesterol and free cholesterol in the liver were significantly lower in rats receiving aflatoxin, while the extra vitamin E supplementation increased these hepatic cholesterol levels. It was concluded that the extra dietary vitamin E or Se supplementation might partially alleviate some of the harmful effects of aflatoxin in rats.
