研究了卤代苯酚对结核菌抑制活性，抗菌活性，呆鲦鱼毒性，水生生物毒性，诱发浮萍萎黄病活性，细胞色素P-450转化活性等六项生物活性分别同卤代苯酚分子连接性指数的相关性。

It is urgent and important for further understanding of these toxicities to develop adequate staging systems and mechanistically driven therapies, in which the quality of life and consistent antineoplastic therapy can be ensured.

了解这些皮肤毒性的机制，制定适当的毒性分期标准，进而给予正确的防治，对确保患者生活质量及抗肿瘤治疗的连续性都十分重要。

Vitality of LDH in nutrient solution detected indirectly reflected toxic effect of Aβ on neurocyte and anti-toxicity of drug on toxic effect of Aβ.

通过测定培养液中的LDH的活力变化，可间接反映Aβ对神经细胞的毒性作用及药物抗Aβ神经毒性的能力。

Objective To study the toxicity of MeHg on photoluminescent bacteria and the inhibitory effects of zinc.

目的：研究甲基汞对明亮发光杆菌的毒性作用及锌对MeHg毒性的拮抗作用。

So low-dose polymyxin B can be used safely in clinic.

多粘菌素B是一种环状阳离子多肽类抗生素，既有抗菌作用，又能拮抗内毒素活性，但其严重的肝肾毒性限制了临床应用，后来有人发现小剂量的多粘菌素B可保留中和内毒素作用，而无抗菌作用，使用安全，值得在临床上推荐使用。
