Abstract: In the present study, the nephroprotective potentials of cinnamon and/or parsley oils was assessed on gentamicin (GM)-induced nephrotoxicity in rats. About 49 male rats were assigned randomly into 7 equal groups (7 rats each). Group 1-3: were orally administered normal saline, cinnamon oil (400 mg kg1 b.wt.) and parsley oil (200 mg kg1 b.wt.), respectively, once daily for 30 consecutive days. Group 4: rats in this group were intraperitoneally injected with GM (100 mg kg1 b.wt.) in the last 10 days (20-30th day) of the experiment. Group 5: rats in this group were given cinnamon and GM while rats in group 6 were administered parsley and GM. Group 7: rats in this group were administered cinnamon and parsley plus GM. At the end of the experiment, rats were sacrificed, serum samples and kidney specimens were collected for biochemical and oxidative status evaluation. Rats administered GM alone showed significant increases in serum concentrations of creatinine, urea and glucose while renal tissue levels of superoxide dismutase, catalase and glutathione reductase were significantly declined. Additionally, the malondialdehyde level was significantly elevated in kidney tissues. Also, GM administration caused renal histopathological alterations. The altered levels of various parameters provoked by GM toxicity were restored towards normal levels by cinnamon and/or parsley oils administration. These results suggested the nephroprotective potentials of cinnamon and/or parsley oils in rats, probably triggered by their antioxidant phytoconstituents.
