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.

Cyclophosphamide (CPA) is an anticancer drug used in the treatment of a variety of neoplastic lesions. On the other hand, treatment with CPA was accompanied by different toxic effects on different body organs. The present work was conducted to study the effect of fenugreek seed extract on histomorphometrical and ultrastructural changes induced by CPA in testes of albino mice. Twenty animals were given CPA (7.0 mg/kg body weight) three times/week orally for 8 weeks and were killed after 4 and 8 weeks. Testis of CPA-treated mice showed many histological alterations including appearance of irregular seminiferous tubules, reduction in the number of all spermatogenic cells, degeneration of Leydig cells and appearance of intertubular hemorrhage. Concerning the ultrastructural changes, abnormalities in spermatogonia (A and B), spermatocytes, round and elongated spermatids were observed. Degenerated Sertoli cells and degenerated interstitial tissue with abnormal Leydig cells were also seen. Moreover, administration of CPA to animals significantly increased malondialdehyde (MDA, lipid peroxidation marker) and decreased superoxide dismutase (SOD) and catalase (CAT). These changes were time-dependent. Treating animals with CPA and fenugreek seed extract (0.4 g/kg body weight) led to an improvement in the histological and ultrastructural pictures of the testis together with reduction in the level of serum MDA and increase in the activities of serum SOD and CAT. In conclusion, the results of the present work indicated that fenugreek had ameliorative effect against testis damage induced by CPA and this may be mediated by its potent antioxidant activities.
