This study was designed to investigate the protective role of taurine against cisplatin-induced kidney injury. Methods: Male Wistar rats were divided into 4 groups (n=8) (1) saline-treated group (2) cisplatin-treated group (10 mg/kg, i.p.), (3) group that received taurine (200 mg/kg, i.p) 1 hr before cisplatin (10 mg/kg, i.p) administration and (4) taurine treated group (200 mg/kg, i.p). The treatment period was 7 days. Animals were then weighed and blood samples were collected from the heart. After sacrifice, kidneys were removed and kept at -70 °C until further analyses. Results: Cisplatin significantly elevated the creatinine and blood urea nitrogen (BUN) serum levels (P<0.05). Pretreatment with taurine resulted in a remarkable reduction of these markers. The catalase activity in cisplatin-treated rats was significantly decreased (P<0.05) and taurine administration could remarkably recover this decreased activity. Malondialdehyde (MDA) content of the kidneys was increased in cisplatin-exposed animals and taurine significantly reduced the amount of MDA. Conclusion: Our data suggest that pretreatment with taurine might be considered as a protective approach in cisplatin-induced nephrotoxicity. cisplatin, taurine, kidney injury, rat 478 485 http://ppj.phypha.ir/browse.php?a_code=A-10-438-4&slc_lang=en&sid=1 maryam noruzi mery_noruzi@ymail.com 320031947532846009905 320031947532846009905 Yes samad zareh 320031947532846009906 320031947532846009906 No
