RESUMO
An elevated level of serum urea and creatinine was observed in doxorubicin (DOX) treated animals indicating DOX-induced nephrotoxicity. Enhanced lipid peroxidation (LPO) in the renal tissue was accompanied by a significant decrease in the levels of reduced glutathione (GSH), glutathione peroxidase (GPx), glutathione reductase (GR) and catalase (CAT) activities. Administration of lycopene (LycT) extracted from tomato to DOX treated mice showed a significant reduction in serum creatinine and urea levels which were associated with significantly low levels of LPO and significantly enhanced level of GSH and related antioxidant enzymes activity (GPx, GR and CAT) when compared to DOX group. Histopathological analysis revealed severe damage in the renal tissue of DOX treated animals. However, animals pretreated with LycT were observed to have reduced damage. Thus, from present results it may be inferred that lycopene may be beneficial in mitigating DOX induced nephrotoxicity in mice.
