The preventive effect of hesperidin as a flavonoid was investigated in mouse bone marrow cells against genotoxicty induced by cyclophosphamide. Mice were orally (gavages) pretreated with solutions of hesperidin at four different doses (50, 100, 200, and 400 mg/kg b.w.) for five consecutive days. Mice were injected intraperitoneally on the fifth day with cyclophosphamide (50 mg/kg b.w.) and killed after 24 h for the evaluation of micronucleated polychromatic erythrocytes (MnPCEs) and the ratio of PCE/(PCE+NCE) (polychromatic erythrocyte/ polychromatic erythrocyte + normochromatic erythrocyte). Three last doses of hesperidin significantly reduced frequency of MnPCEs induced by cyclophosphamide (p<0.0001). Hesperdin at dose 200 mg/kg b.w. reduced MnPCEs 2.37 time and also completely normalized PCE/(PCE+NCE) ratio. Histological examination of bone marrow showed that hesperidin affected on proliferation and hyper cellularity of immature myeloid elements in bone marrow that reduced by cyclophsopahmide. It is obvious that hesperidin, may with antioxidative activity, reduced the oxidative stress and genotoxicity induced by cyclophosphamide in mouse bone marrow cells.
