Resumo
Aneugenic effects of the chemicals with antitumor activity were studied in mouse oocytes in vivo by cytogenetic analysis. In control mice, no oocytes with numerical chromosome aberrations were found. Colchicine (0.2-4 mg/kg), paclitaxel (2.5-7.5 mg/kg), and etoposide (10-60 mg/kg) produced a significant dose-dependent aneugenic effects (induction of up to 25% aneuploid oocytes) and increased the yield of oocytes arrested in the meiotic MI stage and with premature separation of sister chromatid. Paclitaxel induced up to 20% polyploid chromosomes. Doxorubicin (2.5 mg/kg), melphalan (10 mg/kg), and cisplatin (5-10 mg/kg) exhibited weak aneugenic activity (induction of up to 5% aneuploid oocytes). Cyclophosphamide (10-80 mg/kg) had minor effect on the studied parameters. Methotrexate (25-200 mg/kg) exhibited no aneugenic activity, but significantly increased the level of polyploid cells. The observed aneugenic effects included hypo- and hyperploidy in various proportions or hypoploidy, but no solely hyperhaploidy.
