Cisplatin (EBEWE Pharma, Unterach, Austria) is an anti-cancer drug used in chemotherapy. One of the limiting major side effects of cisplatin is nephrotoxicity. Tribulus terrestris (TT) has been used as an synthetic or herbal protective agents for kidney disorders. The present study amid to investigate the Tribulus terrestris Hydroalcoholic extract effect on cisplatin-induced apoptosis in mice kidney. Male adult mice (n= 30) were divided into control group and 4 experimental groups (n= 6). Control group received saline, the first experimental group received cisplatin (5.5 mg/kg) and other three experimental groups received cisplatin (5.5 mg/kg) and different doses of hydroalcoholic extact of TT (100, 300 and 500 mg/kg i.p) respectively. The kidneys were removed after 4 days of injections, and TUNEL assay on mice's kidneys were performed. Weights of body and kidneys and apoptotic index were assessed. Data analysis was performed using one-way ANOVA followed by Tukey's post hoc test. The results showed that cisplatin lead to a reduction in the weight of body and kidney (P <0.01), and increased apoptotic index significantly compared to the control group (P <0.001), while in treated groups with TT, the weights of body and kidney were significantly higher compared with cisplatin group, but apoptotic index did not show significant differences. These parameters reached normal range after administration of fruit extracts of TT for 4 days. The study demonstrates that extract of TT could have protective effect on cisplatin- induced apoptosis of kidney. This may be related to the presence of antioxidant components acting via a multitude of central and peripheral mechanisms.
