Closed-system algal toxicity test was applied to evaluate the toxicity of secondary and tertiary propargylic alcohols to Pseudokirchneriella subcapitata. The effects of propargylic alcohols were evaluated by three kinds of response endpoints, i.e., dissolved oxygen production, cell density, algal growth rate.

bstract：本研究以藻类（Pseudokirchneriella subcapitata）利用BOD瓶进行一密闭式系统之毒性试验，使用溶氧变化量，藻细胞的数量变化，以及以藻类细胞密度变化量计算所得的生长率三个终点，评估二级以及三级炔丙基醇类之毒性，藉由Probit模式求出半致死浓度（50% Effect concentration，EC50）。

The results were suggested that both lanthanide series of elements, such as 〓 and morphine which remarkedly enhanced glutamate neurotoxicity might share the same molecular mechanisms.

在PC12细胞中镧系元素〓能增强Glu的毒性作用，这种作用也能被纳络酮逆转，说明铜系元素〓与吗啡在增强Glu神经毒性方面可能有相同的分子机制。

Dr. Sheau-Farn Yeh's lab found that taiwanin A, isolated from Taiwania Cryptomeriodes, is cytotoxic for several cancer cell lines, especially for human hepatoma Hep G2/A2 and Hep 3B/T2 cells. Besides cytotoxicity, the compound can arrest the cells at G2/M phase. Not only taiwanin A and its derivatives, but also compounds which isolated from the plane Clausena excavata and the roots of Rubia cordifolia have been found to have biological activities.

阳明大学生物化学研究所叶小帆老师实验室在筛选天然抗癌药物时，发现自台湾杉心材所分离出的一种化合物taiwanin A对於许多的肿瘤细胞株均有很强的细胞毒性，其中对人类肝癌细胞株Hep G2/A2与Hep 3B/T2，taiwanin A除了有显著的细胞毒性之外，同时也会造成细胞周期停滞在G2/M相。

The toxicity and effects of different concentrations for two organotin compounds towards Scenedesmus obliquus were studied in this paper with CH3SnCl3 and(CH3)2SnCl2,respectively,as representatives.

有机锡对海洋环境有着很大的破坏作用，为此以一甲基氯化锡(CH3SnC l3)和二甲基氯化锡(CH32SnC l2为代表，研究了不同浓度有机锡对斜生栅藻的毒性影响，并且对两种有机锡的毒性进行了对比试验。

In vitro cytotoxicity experiments the IC50 value for HeLa,K562 and MCF-7 tumor cells is 0.6 mol/L, 0.8 mol/L and 4 mol/L separatedly, while for the normal human fibroblasts cells, even up to 8 mol/L, no cytotoxic effects were observed.

在体外细胞毒性实验中，对人三种肿瘤细胞HeLa、K562、MCF-7具有抑制作用，其IC50分别为0.6 mol/L、0.8 mol/L和4 mol/L，而对于正常人成纤维细胞在酶浓度达到8 mol/L时仍未见明显细胞毒性。

The five kinds of male germ cell cytogenetic assays used to detect genotoxicity of ani-mal drugs to each spermatogenetic stage of male germ cells,such as spermatogonia, primary spermatocytes, secondary spermatocytes,spermatids and spermatozoa,had beensystematically studied.

本文系统地研究了适合我国国情的检测兽药对哺乳动物精原细胞、初级精母细胞、次级精母细胞、精细胞和精子等各个发生阶段雄性生殖细胞遗传毒性的5种测定方法，并首次为国产阿维菌素安全性毒理学评价提供了系统的雄性生殖细胞遗传毒性资料。

Some studies showed that SPs display toxicity to wildlife and human nervous systems.It may cause acute and chronic neurotoxicity to mammal,and the stereoisomeric structure of SPs affects mammals neurotixicity.

随着SPs的广泛使用，其所引起的环境问题也越来越受到人们的关注，特别是SPs作为一类具有神经毒性的杀虫剂，它们对哺乳动物神经系统毒性作用的研究是环境毒理学的一个重要研究方向。
