Effect of fenugreek seed extract on adriamycin-induced hepatotoxicity and oxidative stress in albino rats

The purpose of this work was to evaluate the effect of aqueous extract of fenugreek seeds against hepatotoxicity induced in albino rats by the anticancer drug adriamycin (ADR). Animals were given single dose of ADR (10 mg/kg body weight) and were killed after 2 and 4 weeks. Liver of ADR-treated animals showed histopathological and biochemical alterations. The histopathological changes include hepatic tissue impairment, cytoplasmic vacuolization of the hepatocytes, congestion of blood vessels, leucocytic infiltrations and fatty infiltration. Moreover, the expression of proliferating cell nuclear antigen was increased in ADR-treated rats. The liver enzymes, aspartate aminotransferase (ALT) and alanine aminotransferase (AST) were increased in the sera of treated rats. Moreover, ADR significantly increased the concentration of malondialdehyde (MDA) and decreased the activities of superoxide dismutase (SOD) and catalase (CAT) in hepatic tissue. Treating animals with ADR and aqueous extract of fenugreek (0.4 g/kg body weight) seeds led to an improvement in histological and biochemical alterations induced by ADR. The biochemical results showed that AST and ALT appeared normal together with reduction in the level of MDA (lipid peroxidation marker) and increase in SOD and CAT activities. It was concluded from this study that the aqueous extract fenugreek seeds has a beneficial impact on ADR-induced hepatotoxicity due to its antioxidant effect in albino rats.
