Aim: The aqueous extract of leaves of Murraya koenigii was studied for its renoprotective potential against unilateral renal ischemia reperfusion (RIR) injury in male Wistar rats. Materials and Methods: Healthy adult male Wistar rats were divided into five groups (n = 8) and were treated with 200 mg/kg., p.o. of aqueous extract of M. koenigii (AEMK) for 30 days to assess both preventive and curative effects of AEMK. Except Group I, RIR was induced to all the groups by clamping the left renal artery using artery clamp for 1 h followed by reperfusion by removing the clamp. Groups II and III underwent RIR at 30 th day whereas RIR was induced in Groups IV and V at 1 st day of treatment schedule. Biochemical parameters (serum creatinine, blood urea nitrogen, serum total protein and serum Na + ), urinary parameters (urine output, urinary creatinine, urinary urea, urinary total protein, urinary Na + ), in vivo anti-oxidants, renal myeloperoxidase (MPO) activity and histopathology of kidneys were monitored. Statistical significance was set at P < 0.05. Results: Rats were treated with AEMK significantly (P < 0.05) restored the serum and urinary parameters with significant (P < 0.05) improvement in endogenous anti-oxidants such as superoxide dismutase, catalase and reduced glutathione and decreased levels of malondialdehyde and renal MPO when compared with the control groups. Histopathological examination also supported the biochemical and urinary tests. Conclusions: Aqueous extract of M. koenigii possesses both preventive and curative effects against RIR injury.
