The present study included the recognition of alpha-methrin (Serin) and actara (Cruzer) insecticides medium lethal dose LD50, which was found to be 150 mg alpha-methrin/Kg body weight and 1875 mg actara / Kg body weight. By consideration of (LD50) values three doses of each insecticide were orally administered to male albino rats for 15 and 30 days period, to study their effects on the levels of some enzymatic, non enzymatic antioxidans and lipid peroxides in serum and tissues of albino rats.
The rats were divided into 7 groups; the control group which administered with distilled water, the first to third group were administered with 2.5, 5, 10 mg /Kg body weight alpha-methrin respectively, the fourth to sixth group were administered with 100, 150, 200 mg /Kg body weight actara respectively on comparison to control group with that treated with either alpha-methrin or actara. The results showed a significant decrease in non enzymatic antioxidant (uric acid concentration and glutathione) level and an increase in the activities of superoxide dismutase (enzymatic antioxidant) and a significant increase in malondialdehyed level in serum blood of rats treated with either alpha-methrin or actara. The results also showed a significant decrease in level of glutathione accompanied with significant increase in malondialdehyed level in tissues of (brain, heart, liver and kidney). The rats which administered with different concentrations of alpha-methrin insecticide, showed more effects than that groups administeared by actara. These results indicated that the alpha-methrin has more poisonous effects than actara insecticide .
