Abstract: 目的:用微核试验初步评价芦荟提取物的遗传毒性.方法:健康昆明种小鼠分别灌胃芦荟提取物样品1.1,2.2,4.4 g·kg-1,qd,连续4 d,同时设阴性(注射用水,腹腔注射)和阳性对照组(环磷酰胺,腹腔注射),每组10只,雌雄各半.每只小鼠的骨髓涂片计数1 000个嗜多染红细胞(PCE),记录含微核的嗜多染红细胞(MNPCE)数,计算微核率.结果:芦荟提取物低、中、高3个剂量组的微核率依次为(13.60±3.50)‰,(20.60±3.94)‰和(17.30±4.16)‰,环磷酰胺阳性对照组的微核率为(18.40±1.07)‰.与阴性对照组的微核率[(4.40±0.84)‰]比较,芦荟提取物低、中、高3个剂量组和环磷酰胺组均显著升高(P<0.01),中剂量组的微核率最高,还显著高于阳性对照组(P<0.05).结论:芦荟提取物能明显诱导小鼠骨髓细胞微核率增加.
