Attenuation of cisplathin-induced toxic oxidative stress by propofol

Antioxidant effects of propofol (2, 6-diisopropylphenol) were evaluated against cisplatin-i‎nduced oxidative stress in rat. In this experimental study, 20 male rats were equally divided into 4 groups (5 rats each), and were treated by propofol (10 mg/kg/day, IP), or cisplatin (7 mg /kg/day, IP), or both. G‎roup one was control, while group 2 was given cisplatin (7 mg /kg/day, IP). Animals of the third group received only propofol (10 mg/kg/day, IP). Group 4 was given propofol with cisplatin once per day for 7 days. After treatment, blood urea nitrogen, creatinine levels, and oxidative stress m‎arkers such as total thiol groups (TTG), lipid peroxidation (LPO), and total antioxidant ‎capacity (TAC) were measured. Oxidative stress induced by cisplatin, was evident by a significant increase in LPO and decrease in TTG and TAC. Propofol recovered ‎cisplatin -induced changes in TAC, TTG and LPO in blood. It is concluded that oxidative ‎damage is the mechanism of cisplatin toxicity, which can be recovered by propofol.‎
