The protective effects of Prunus armeniaca L (apricot) against methotrexate-induced oxidative damage and apoptosis in rat kidney

This study was conducted to evaluate a possible protective role of apricot in apoptotic cell death induced by methotrexate (MTX) and renal damage by different histological and biochemical parameters. Twenty-eight rats were divided into four groups, control, apricot, methotrexate, and apricot + methotrexate. Methotrexate induced renal failure, as shown by significant serum creatinine and urea elevation. Additionally, the results indicated that methotrexate significantly induced lipid peroxidation and reduced antioxidant activities in rats. In contrast, apricot significantly prevented toxic effects of methotrexate via increased catalase, superoxide dismutase, and glutathione levels but decreased formation of malondialdehyde. Also, it was determined that exposure to methotrexate leads to significant histological damage in kidney tissue such as glomerulosclerosis and apoptosis. On the other hand, these effects can be eliminated with apricot diet. These data indicate that apricot may be useful in preventing undesirable effects of MTX such as nephrotoxicity.
