METHODS: the biological safety was evaluated through the experiments including hemolysis test, short-term systemic toxicity test, oral mucous membrane irritation test and cytotoxicity test (MTT test).
方法：分别通过溶血试验、口腔黏膜刺激试验、细胞毒性试验(MTT法)和急性全身毒性试验，初步评价纯钛表面聚吡咯涂层的生物安全性。
Methods A short-term and a subchronic test on rats were respectively carried out to study the toxicity of low-dose T-2 toxin by observing the histopathological changes of transparent cartilage.
方法利用大鼠进行短期毒性实验和亚慢性毒性实验，通过透明软骨的组织病理改变来观察低剂量T-2毒素对软骨的损伤作用。
No obvious diversity (P>0.05) was found by comparing the negative control group with the short-term toxicity test group in terms of weight, food-intake, food utilizing ratio of the mice;
短期毒性试验的动物体重、进食量、食物利用率与阴性对照组比较，差异均无显著性（P>0.05）；
