| Summary: | The clinical use of an immunosuppressive cyclosporine A (CsA) is limited by its serious nephrotoxic effect. Evidences have suggested the role of oxidative stress in its pathogenesis. Shallot (Allium ascalonicum L.) has recently been shown to possess antioxidative and free radical scavenging abilities. The present study was undertaken to investigate the possible beneficial effect of shallot extract on renal injury caused by CsA. Male Wistar rats were treated orally with vehicle, CsA (25 mg/kg), shallot extract (1 g/kg), and CsA plus shallot extract for 21 days. Renal function, histopathology, tissue malondialdehyde (MDA) and glutathione (GSH) levels were evaluated 24 h after the last treatment. CsA-induced nephrotoxicity was evidenced by increased blood urea nitrogen and serum creatinine, but decreased urea and creatinine clearance. The kidney of CsA treated rats exhibited severe vacuolations and tubular necrosis. CsA also induced oxidative stress, as indicated by increased renal MDA and reduced GSH concentrations. Administration of shallot extract along with CsA counteracted the deleterious effects of CsA on renal dysfunction, oxidative stress markers, and morphological changes. These data indicate the protective potential of shallot extract against CsA nephrotoxicity and suggest a significant contribution of its antioxidant property to this beneficial effect. © 2008 Elsevier Ltd.
