Abstract

Introduction: Paraquat is a quaternary nitrogen herbicide which induces kidney toxicity due to producing oxidative stress. We have investigated the potential protective effects of silymarin on paraquat-induced renal toxicity. Methods: Twenty-four male rats were divided into three groups, group 1, control group; group 2, rats that received paraquat only (25 mg/kg b.w./day, po); animals in group 3, was treated with paraquat (25 mg/kg b.w./day, po) and silymarin (50 mg/kg b.w./day, po). Then, the serum and tissue parameters of the oxidative stress and renal histopathological changes were examined. Results: In group 2 which received paraquat only, a remarkable increase (P<0.05) was observed in serum creatinine, urea, malondialdehyde (MDA), protein carbonyl, and tumor necrosis factor alpha (TNF-α). Also, there was a significant decrease in renal superoxide dismutase, catalase (CAT), ferric reducing ability of plasma (FRAP) and vitamin C in the second group. Oral administration of silymarin significantly decreased serum urea, creatinine, protein carbonyl, MDA, and TNF-α as well as renal histopathological changes. Conclusion: The present study suggests that silymarin has anti-inflammatory and nephroprotective effects against nephrotoxicity caused by paraquat.
