预试验分空白对照组和0.05mg/ml、0.5mg/ml、5mg/ml三种浓度中药组,分别作用于各10只在稻草水煮液培养基中的原生动物草履虫,12h、24h、36h、48h后观察草履虫生长情况;平行试验各三组.据预试验结果,正式实验设置1mg/ml、2mg/ml、3mg/ml为低浓度组,4mg/ml、5mg/ml、6mg/ml为中浓度组,7mg/ml、8mg/ml、9mg/ml为高浓度组,并设置空白对照组,共十组;分别作用于各10只草履虫,1h、3h、6h后分别观察草履虫的应激性、运动状态,计数死亡和增殖数;平行实验各三组.
在预试验的48h内,草履虫每隔12h个数增长一倍左右;而超过12h,每组平行试验的结果,随着时间延长差异度加大.当药物TGXT浓度为5mg/ml时,草履虫开始出现死亡;与空白对照组相比,增殖下降.急性毒性实验6 h内,药物TGXT低浓度组未见草履虫死亡.而中、高浓度组,随着药物浓度、时间增加,毒性也增加.药物5mg/ml或6mg/ml作用1h、3mg/ml作用3h或6h时,草履虫运动较对空白照组减缓.而7mg/m作用1h、4mg/ml 作用3h或6h时,草履虫出现死亡.

答案和解析
The pre-experiment was divided into blank control group and 0.05mg/ml,0.5mg/ml,5mg/ml three concentrations of traditional Chinese medicine group,respectively,the role of 10 in straw boiled liquid medium protozoan Paramecium,12h,24h,observed after 36h,48h paramecium growth; parallel experiments the three groups.According to the pre-test results,a formal experiment set 1mg/ml,2mg/ml,3mg/ml low concentration group,4mg/ml,5mg/ml,6mg/ml concentration group,7mg/ml,8mg/ml 9mg / ml for the high concentration group,and set the blank control group,a total of 10 groups; were each 10 paramecium,1h,3h,6h were observed in Paramecium stress state of motion,counting death and proliferation of the number; parallel experiment all three groups.
Within 48h of pre-test,Paramecium every 12h number doubled; and more than 12h,the results of each group of parallel test increased with the time difference degree.When drugs TGXT concentration of 5mg/ml,paramecium death; compared with the control group,decreased proliferation.Acute toxicity test within 6 h,low concentrations of the drugs TGXT no the paramecium death.In high concentrations,with increased drug concentration,time,toxicity also increases.Drug 5mg/ml or 6mg/ml-role 1h,3mg/ml for 3h or 6h,paramecium movement compared with blank control group slow down.7mg / m,the role of 1h,4mg/ml 3h or 6h,paramecium death.选我吧,求你了,我很需要这30分,
