Evaluation of the effects of the hydroalcoholic extract of Terminalia chebula fruits on diazinon-induced liver toxicity and oxidative stress in rats

Objective: Diazinon causes oxidative stress and dysfunction of the liver. This study was undertaken to evaluate the effects of the hydroalcoholic extract of Terminalia chebula, on some biochemical and histopathological parameters of liver tissue in diazinon-administered rats. Materials and Methods: Wistar rats were orally administered with 25 mg/kg body weight diazinon. Vehicle (distilled water) and silymarin (50 mg/kg body weight) were used as the negative and positive control groups, respectively. Diazinon-administered groups were treated with T.chebula (Terminalia chebula) fruit extract (200, 400, and 800 mg/kg). After 15 days of treatment, the blood specimens and liver samples were examined. Results: In diazinon-treated group, the levels of serum urea, high density lipoprotein (HDL), and liver superoxide dismutase (SOD), catalase (CAT), and vitamin C significantly decreased (p
