本文报道了以动物实验模型研究母亲饮酒对胎儿的细胞遗传学影响。实验用10～14周末曾交配过的成熟雌性小鼠,于妊娠前4周中和妊娠期间任其自由摄取0％、10％、20％、40％酒精和固型饲料,并记录摄取量。投酒精四周后的雌鼠平均增重,仅在40％组明显降低,对胎仔的影响,在0％～20％组的着床数、吸收胎数等未见变化,仅40％组的吸收胎数增加、胎 This article reports the experimental animal model to study the effects of maternal drinking on fetal cytogenetics. Mature female mice, who had been mated at the end of 10-14 weeks, were given free access to 0%, 10%, 20%, 40% alcohol and solid feed during the first 4 weeks of gestation and during pregnancy, and their intake was recorded. The average weight gain of female mice after 4 weeks of alcohol injection was significantly lower than that of the 40% group. The effects on the fetuses were similar between 0% and 20% Increase in the number of tires, tires
