有毒性的

This property is why it is a valued base for paints and varnishes, but this varnish is chemically closely related to the age pigment that forms "liver spots" on the skin, and similar lesions in the brain, heart, blood vessels, lenses of the eyes, etc. The image of "hard, white saturated coconut oil" isn't relevant to the oil's biological action, but the image of "sticky varnish-like easily oxidized unsaturated seed oils" is highly relevant to their toxicity.

这个属性是为什么它是一个有价值的基地，涂料，油漆，清漆，但这个是化学密切相关，年龄色素的形式"肝点"，对皮肤，和类似的病变，在脑，心，血管，镜头的眼睛等的形象，"硬，白饱和的椰子油"是不相关的石油的生物行动，但形象"粘研磨剂一样容易氧化的不饱和籽油"是高度相关的毒性。

Conlusions:Above results suggest: the main mechanisms of Tau preventing cytoxicity against Mn were of declining Mn-induced apoptotic effects, protecting DNA damage and declining free Ca2+ concentrtion in cytoplastic of neurons.

实验结果提示牛磺酸干预锰神经细胞毒性的机理，主要包括降低锰对神经细胞凋亡的诱导作用、对锰造成的神经细胞DNA损伤有明显的保护作用，明显降低锰造成的培养神经细胞升高的钙离子浓度。

Polyether based polyurethanes are among the most interested polymers which have been used suitably for the biomedical applications, especially in cardiovascular system. In order to meet the requirements of the artificial heart program in our college, two sorts of polyether based polyurethane elastomers, PU-BD and PU-MC, were synthesized both based on prepolymer formed by the reaction of polytetramethylene ether glycol and diphenyl methane-4, 4′-diisccyanate, with 1, 4-butanediol and 3, 3′-dich...

本文介绍了两种聚醚型聚氨酯弹性体PU—BD和PU—MC的合成路线，两种弹性体的物理机械性能(曲挠、抗张强度、伸长率等)的测试结果，两种弹性材料的生物相容性试验(凝血时间，慢性组织相容性、细胞毒性等)及其结果、各种试验结果表明，这两种聚氨酯弹性材料的耐曲挠性能和生物相容性都已达到现阶段人工心脏研究工作的要求，为两种有希望的医用高分子材料。

The rest of the Sentinels, though, saw Garuda more in terms of its tangible challenges, and foremost among these was its very atmosphere: though Earthlike in composition, it was essentially toxic to all but the planet's indigenous life-forms.

然而，哨兵中的其他人更注重嘎鲁达世界那些实实在在的挑战，首当其冲的便是它的大气层：尽管成分和地球大气相仿，但对于非本星球土著的生命形式来说，基本上都有毒性。

The cytotoxic effect of α-eleostearic acid and triacylglycerols of tung oil against human tumor cells may be attributable to conjugated trienoic structure.

结果提示，除了α-桐酸的共轭三烯结构是桐油甘油三酯的细胞毒性的物质基础之外，含共轭亚麻酸的甘油三酯的分子结构对其抗肿瘤功效也有重要贡献。

These results suggest that pyriproxyfen obviously influences the larval growth to adult worker bees, especially in the pupal growth. The lower dose of pyriproxyfen results in abnormal eclosion, and more effects respond to the increasing doses, the treated larvae gradually appear the failure to eclosion, melanic death in the pupal stage, and death in the larval stage.

上述结果显示，百利普芬对成蜂的毒性较低，却会明显影响蜜蜂幼虫的生长发育，低剂量会造成蜜蜂羽化不完全，随著剂量的增加，处理幼虫的发育有提早的现象，处理幼虫会渐次出现蛹体变黑死亡，羽化失败死亡，甚至幼虫期即死亡的现象。

(1)SCG is a sensitive, simple and economic method in evaluating the cytotoxicity of SM in toxication and the degree of intoxication, and with good prospects in early diagnasis;(2)The cytotoxicity caused by the elevation of NO induced by the NOS activity after intoxication might be one of the mechanisms of SM intoxication;(3)Apoptosis participates in the process of SM intoxication also might be one of the mechanisms of SM intoxication.

(1)SCG法敏感、经济、简便，可用于硫芥中毒细胞毒性、中毒程度的评价，在早期诊断上有良好的应用前景；（2）中毒后因NOS的活性升高导致NO的升高而产生细胞毒作用可能是硫芥的中毒机制之一；（3）细胞凋亡参与了硫芥的中毒过程，亦可能是其中毒机制之一。

Nevertheless, as to the antioxidant activity, HA andβ-PPA could also protect cells against oxidative stress within a relatively short duration time when compared to α-Toc. TS didn't show any effect against oxidative stress in the range of our treated doses. In the remanding experiments, all of HA,β-PPA and TS didn't show any activity in the protection of rat primary hepatocyte cells against H2O2-induced oxidative stress, and in the inhibition of telomerase.

在前骨髓白血球HL-60程式化死亡系统中，HA会诱发HL-60的程式化死亡，β-PPA和AMBL-029C-TS只会直接诱发细胞的坏死，在观测抗氧化效果方面，以对HL-60细胞不呈细胞毒性的浓度观察，得知HA和β-PPA在短时间内有保护细胞不受氧化压力的能力，但在长时间后，对抗氧化压力的效果不如α-Toc明显，AMBL-029C-TS则没有明显抗氧化压力的能力。

Cardiac toxicity was minimal in both groups, the editorial notes, adding that this is a major adverse effect of trastuzumab. However, the trialists point out that there was a bias, as they had selected women who had normal cardiac function after having received various other therapies (including anthracyclines and taxanes) as well as trastuzumab. Also, since the duration of observation was limited, the possibility of late events cannot be excluded."Nevertheless, the low incidence of adverse cardiac events is reassuring," they comment.

主编表示，两组之间发生心脏毒性的比例相似，且这是trastuzumab主要的副作用；然而，研究者指出其中有误差，因为他们挑选已经接受其它不同治疗（包括anthracyclines类药物与taxanes类药物）以及trastuzumab后心脏功能正常的病患；同时，因为试验观察时间长度有限，晚期发生不良反应的可能性并不能排除；他们的评论是，不管如何，心脏不良反应发生率低是可靠的。
