长期酒精暴露对秀丽隐杆线虫生殖能力的损伤作用研究[摘要] 目的应用秀丽隐杆线虫研究酒精的生殖损伤作用及其

对子代线虫运动能力的影响。方法将l4期秀丽隐杆线虫暴露在含有不同浓度酒精(1%、2%、3%、4%、5%)并涂有大肠埃希菌op50的琼脂培养基(ngm)中,在体视显微镜和荧光显微镜下统计后代数目、子宫内受精卵数目、卵母细胞数目,计算排卵速率并观察子代线虫的运动行为。结果与对照组比较,长期暴露在含酒精浓度分别为2%、3%、4%、5%的ngm培养基中的线虫的后代数目、子宫内受精卵数目、卵母细胞数目均有显著降低(p 2 结果

2.1 长期暴露在不同浓度酒精条件下线虫后代数目的改变

与对照组相比,长期暴露在酒精浓度为1%条件下,线虫的后代数目无显著性变化,2%、3%、4%、5%条件下线虫后代数目明显降低(p [3] ledig m,misslin r,vogel e,et al. pateral alcohol exposure: developmental and behavioral effects on the offspring of rats[j]. neuropharmacology, 1998, 37(1):57-63.
