| Abstract: | The influence of N-acetylcysteine (ACC) on the cytogenetic effects of etoposide in F1 CBA × C57BL/6 mice was studied. Etoposide introduced intraperitoneally in doses of 10, 20, 40, and 60 mg/kg has a dose-dependent clastogenic activity and has an aneugenic effect with the induction of mainly hypohaploid oocytes. ACC significantly decreases the aneugenic and clastogenic activity of etoposide (20 mg/kg) in oocytes of 6-, 9-, and 12-week-old mice during triple introduction at a dose 200 mg/kg per os. The most pronounced anticlastogenic ACC activity (an 80% decrease) was registered in 9-week-old females; a 100% decrease in aneugenesis was detected in 6-week-old female mice. |
