| Abstract | ||
| Background: Cisplatin (CDDP) is a cytotoxic therapeutic agent that causes many physiological adverse effects such as nephrotoxicity. Although N-acetylcystein (NAC) a thiol containing antioxidant, has been documented to be effective in attenuating CDDP induced renal injury, the precise mechanisms involved in its renoprotection have not been completely clarified. Methods: Four groups of albino rats were used. The first group injected by saline as control, the second by NAC (i.p.), the third by a single bolus of cisplatin (i.v.), and the last by NAC/CDDP, after 5 days from CDDP injection, investigations were conducted on the levels of serum urea and creatinine, oxidant/antioxidant status by estimation of malondialdehyde, catalase and reduced glutathione, and renal and systemic tumor necrosis factor-alpha (TNF-α). Also, renal tissues were examined histopathologically. Results: Administration of cisplatin to rats induced a significant increase in serum urea and creatinine levels in addition to severe alterations in renal tissue architecture. Cisplatin also increased malondialdehyde and decreased glutathione, and catalase in renal tissues. Also, CDDP increased both renal and systemic TNF-α. Administration of NAC markedly reduced the cisplatin-induced higher serum creatinine and urea levels and counteracted the effects of cisplatin on oxidative stress markers, protected the tissues from the cisplatin-induced lipid peroxidation, and increased TNF-α and improved renal tissue architecture. Conclusion: NAC protection is mediated by preventing the decline of antioxidant status, inhibit malondialdehyde and TNF-α and prevent necrosis and apoptosis from kidneys. These results have implications in use of NAC in human application for protecting against drug-induced nephrotoxicity. | ||
