Lead is a serious poison causing serious injury or death. Current study was designed to investigate the potential protective effect of selenium (Se) and alpha-tocopherol (alpha-toc) against the hepatic and renal toxicity of lead acetate in Oreochromis niloticus. Two hundred and twenty five O. niloticus were divided into five groups; control, lead acetate treated (73.40 mg/liter), Se treated (4 mg sodium selenite/ kg diet), alpha-toc treated (200 mg/kg diet) plus Se + alpha-toc co-treated groups for 10 weeks. Levels of aspartate aminotransferase (AST), alanine transaminase (ALT), total protein, urea, creatinine, calcium (Ca), inorganic phosphate (P), magnesium (Mg), superoxide dismutase (SOD), reduced glutathione (GSH) and the lipid peroxidation index (MDA) were determined The results revealed an increase in the levels of liver enzymes, urea, creatinine and MDA; meanwhile, the total protein, Ca, P, Mg, SOD and GSH were decreased. Therefore, it could be concluded that selenium (Se) and alpha-tocopherol (alpha-toc) may be useful tool to minimize the toxic effects of lead toxicity by its potent antioxidant activity.
