Özet

Cyclophosphamide (CP) is a common anticancer drug, but its use in cancer treatment is limited due to its severe toxicities induced mainly by oxidative stress in normal cells. Reactive oxygen species (ROS) lead to multiple organ injuries, including the kidneys. Selenium (Se) is a nutritionally essential trace element with antioxidant properties. In the present study, the possible protective effect of Se on CP-induced acute nephrotoxicity was investigated. Forty-two Sprague-Dawley rats were equally divided into six groups of seven rats in each. The control group received saline, and other groups were injected with CP (150 mg/kg), Se (0.5 or 1 mg/kg), or CP + Se intraperitoneally. Total antioxidant capacity (TAC), total oxidant state (TOS), oxidative stress index (OSI), creatinine, and cystatin C (Cys C) levels were measured in the sera. In addition, kidney tissues were examined histologically. In the CP alone treated rats, creatinine, Cys C, TOS, and OSI levels increased, while TAC level decreased. CP-induced histological damages were decreased by co-treatment of Se and biochemical results supported the microscopic observations. In conclusion, our study points to the therapeutic potential of Se and indicates a significant role of ROS in CP-induced kidney toxicity.
