Evaluation of Prophylactic and Therapeutic Roles of N-Acetylcysteine on Biochemical and Oxidative Changes Induced by Acute Poisoning of Diazinon in Various Rat Tissues

Background: Exposure to diazinon (DZN) as an organophosphorus insecticide is associated with reducing the antioxidant capacity of cells. N-acetyl cysteine (NAC) is widely used in clinics to treat several diseases related to oxidative stress. Objective: The current study was aimed to evaluate the prophylactic and therapeutic roles of NAC on biochemical and oxidative changes induced by acute poisoning of DZN in various tissues of male Wistar rats. Methods: Thirty rats were divided into five groups: control group received corn oil as DZN solvent; DZN group received 100 mg/kg of DZN; NAC group received 160 mg/kg of NAC; NAC-DZN and DZN-NAC groups received 160 mg/kg of NAC before and after 100 mg/kg of DZN injection, respectively. Plasma and various tissues were prepared and evaluated for the measurement of the biochemical parameters and oxidative stress biomarkers. Results: Both prophylactic and therapeutic treatments by NAC ameliorated the increased lipid peroxidation and decreased glutathione level and superoxide dismutase, catalase and glutathione S-transferase activities in tissues (P
