This factor causes induces oxidative stress in different tissues. The aim of this study was to study the protective role of vitamins E and C as antioxidant in reduction of DZN-induced oxidative stress in rat kidney. Materials & methods: In present experimental study, male Wistar rats were randomly divided into six groups including: control group received (corn oil as a DZN solvent), DZN group (100 mg/kg), vitamin E group (150 mg/kg), vitamin C group (200 mg/kg), vitamin E+DZN group and vitamin C+DZN group, intraperitoneally. 24 hours after injection, rats were anesthetized by ether and kidneys were removed quickly. After tissues hemogenation, superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST) and lactate dehydrogenase (LDH) anzymes activities and glutathione (GSH) and malondialdehyde (MDA) concentrations were determined by biochemical methods. Findings: DZN increased SOD, CAT and GST activities in kidneys. Also, reduced GSH concentration and increased concentrations of MDA were observed. Administration of vitamins E and C prevent changes in these parameters in the kidneys. Discussion & Conclusion: DZN by increasing lipid peroxidation membrane and reduced GSH concentration cause oxidative stress in kidneys. Administration of vitamins E and C as an antioxidant decrease DZN toxicity via purging the free radicals but not completely. CP - IRAN IN - LG - eng PB - sjimu PG - 44 PT - Research YR - 2015
