目的探讨寿胎丸对TA97、TA98、TA100、TA102菌株基因回变菌落的影响,对其遗传安全性进行研究.方法采用直接平皿掺入技术,设寿胎丸不同剂量组,并对TA97、TA98、TA100、TA102系列菌株进行体外染毒,观察其回变菌落增长状况.结果在0.8至200.0 mg/皿的不同测试浓度,+S9与-S9两种测试系统条件下,其作用的4种测试菌株的回变菌落数与阴性对照相比元明显增加.回变菌落背景正常,未显示其有抑菌作用,且无剂量-反应关系.结论寿胎丸药液在本试验所确定的200.0 mg/皿剂量范围内,初步认为对TA系列测试菌株无明显致DNA碱基置换及移码突变性.

Objective To investigate the effect of Shoutai pills on bacterial strains TA97,TA98, TA100 and TA102 of genie mutation bacterial strains TA97, TA98, TA100 and with different doses of Shoutai pills groups, Results The TA bacterial reverse mutation and study hereditary toxicity TA102 were poisoned with of them. Methods The utensil means in vitro and the DNA variety of TA bacterial was observed. induced by Shoutai pills was not increased under mixing S9 or non-mixing S9, compared with that in control group. Conclusions The Shoutai pills in the range...
