ABSTRACT

Acute dose of organophosphorus pesticide Triazophos (O,O-diethyl O-1-phenyl-1H-1,2,4-triazol-3-yl phosphorothioate; Tz) administered orally affects oxidative stress parameters and the histo-architecture of liver, kidney and brain tissues. The results indicate a dose dependent induction of oxidative stress as evident by increased malondialdehyde level and decreased antioxidant defense including glutathione and superoxide dismutase activity in rat liver, kidney and brain. AChE activity was found significantly decreased in the Tz treated groups as compared to the vehicle control (DMSO) group. Histopathological examination of liver, kidney and brain in Tz treated rats revealed medullary congestion and hydropic degeneration of hepatocytes in liver and medullary congestion in kidney. However, no significant histopathological changes were observed in brain tissues.
