At the end of the experiment, all of the rats were killed after the last time when the rats were treated with medicine. And the serum was collected to observe blood picture, function of liver kidney, and other important organs were observed, too. The other half number of the rats was killed in two weeks when the rats were stopped taking medicine.

实验结束时分两批处死动物，第一批于最后一次给药后24小时处死，每组处死动物的1／2，作为给药期的观测，取血测血象及肝肾功能，取重要脏器作组织病理学检查；第二批将余下的动物于停药后继续饲养2周后处死，作为恢复期观察，与给药期作相同指标的检测，以了解毒性反应的可逆程度和可能出现的延迟毒性反应。

Results The observation from HE stain showed the most toxic effect of HCT-8 cells at 800μg/ml for 8h. The toxicity of HCT-8 cels in each experiment group(25~800μg/ml)was higher than that of matched control except 12.5%μg/ml.
