RESUMO

This study investigated the antioxidant effects of pecan nut (Carya illinoensis) shell aqueous extract (AE) on toxicity induced by cyclophosphamide (CP) in the heart, kidney, liver, bladder, plasma and erythrocytes of rats. Rats were treated with water or pecan shell AE (5%) ad libitum, replacing drinking water for 37 days up to the end of the experiment. On day 30, half of each group received a single administration of vehicle or CP 200 mg/kg-ip. After 7 days, the organs were removed. Rats treated with CP showed an increase in lipid peroxidation (LP) and decrease in reduced glutathione (GSH) levels in all structures. Catalase (CAT) activity was increased in the heart and decreased in liver and kidney. Besides, CP treatment decreased plasmatic vitamin C (VIT C) levels and induced bladder macroscopical and microscopical damages. In contrast, co-treatment with pecan shell AE prevented the LP development and the GSH depletion in all structures, except in the heart and plasma, respectively. CAT activity in the heart and liver as well as the plasmatic VIT C levels remained unchanged. Finally, AE prevented CP-induced bladder injury. These findings revealed the protective role of pecan shell AE in CP-induced multiple organ toxicity.
