Objective: To investigate the adverse effect of exposure to acetylsalicylic acid (ASA), diazinon (DIA) and their combination on oxidant/antioxidant status in rat erythrocytes and the ameliorating role of selenium (Se). Methods: Rats were oral administered ASA at the maximum administration dose (1 350 mg/personal/d=2.5 mg/kg body weight/d), DIA at a dose of 20 mg/kg body weight/d and Se at a dose of 200 µg/kg body weight/d and their combinations for 28 consecutive d. Results: Administration of DIA, ASA and ASA+DIA lead to a significant increment (P≤0.05) in lipid peroxidation as evidenced by the increase in erythrocytes MDA levels by 61.8%, 20.79% and 105.62%, respectively. Co-administration of Se to treated rats modulated the augmentation of MDA levels. Administration of DIA, ASA and ASA+DIA lead to significant decreases (P≤0.05) in the activities of catalase, superoxide dismutase and glutathione peroxidase enzymes when compared to the control group. The most influence and decreases in the activities of the aforementioned enzymes were observed in the treatments of ASA+DIA by 30.53%, 43.42% and 48.31%, respectively. However, co-administration of Se mitigated the significant decreases of superoxide dismutase, catalase and glutathione peroxidase activities to by 14.47%, 15, 36% and 12.29%. Conclusions: It can be concluded that DIA and ASA induced oxidative stress and lipid peroxidation in rat erythrocytes. The results reveal the pronounced ameliorating effect of Se in DIA and ASA intoxicated rats. It is supposed that antioxidant supplementation may be beneficial for the people using ASA for longer periods and exposure to pesticides.
