Background: Malathion (MT), an organophosphorus pesticide, induces hepatotoxicity and is associated with hyperglycemia and the development of diabetes mellitus.
Objectives: This study was aimed to evaluate the effects of sub-acute exposure to sub-lethal dose of MT in the liver of diabetic rats.
Methods: Non-diabetic and streptozotocin-induced diabetic rats received MT at a dose of 150 mg/kg/day orally. After 28 days, fasting blood glucose, Glucose Tolerance Test (GTT), serum aminotransferases, and liver histopathology and antioxidant status were examined.
Results: MT impaired GTT, caused alteration in histopathology of histopathology and antioxidant status of liver in non-diabetic rats. Impairment in GTT did not observe in diabetic rats exposed to MT, but histopathology changes and antioxidant status alteration was more severe.
Conclusion: Repeated sub-lethal dose of MT exacerbated hepatotoxicity in diabetes condition through further impairment in the antioxidant defense system.
