Cyclophosphamide (CP), a chemotherapeutic agent, induces hepatotoxicity as one of its side effects. Therefore, the aim of the present study is to investigate the potential hepatoprotective effects of fullerene C60 nanoparticles (C60) against the high toxic dose of CP. Twenty five albino rats were randomly assigned to 5 groups (n=5 per group). Group 1 served as a control. Group 2 received 200mg/kg of CP once intraperitoneally, while group 3 treated with the same CP dose plus C60 (4mgkg, orally) daily for 10days. Group 4 exposed CP and ZnCl2 (4mgkg, orally) daily for 10days. Group 5 exposed to CP and co-treated with C60 and ZnCl2. One day after last treatment, blood and livers were collected for hematological, biochemical and histopathological investigations. C60 normalized significantly RBCs, HB, PCV, WBCs and platelets numbers compared to CP-exposed rats. Moreover, liver enzymes namely ALT, AST and ALP revealed that CP elevated their levels and C60 significantly (p<0.05) reduced them to basal levels. The level of oxidative stress marker namely, MDA was elevated upon CP exposure and normalized by C60 treatment. In addition, antioxidant systems e.g. GSH, CAT and SOD were depleted from liver tissue due to CP toxicity these were recovered by C60 administration. The hepatoprotective effects of C60 on tested parameters were comparable with ZnCl2 and neither additive nor synergistic effect was observed. Histopathogically, severe liver degeneration was recorded after CP treatment, however, only mild changes were observed after C60 administration. Our data suggest that C60 improves both blood and hepatic parameters altered by cyclophosphamide-induced toxicities. The current study is of clinical relevance particularly, application of C60 as a monotherapy or in combination to ameliorate the CP side effects in cancer-treated patients.
