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。

The potential for the combination of drugs that have activity at both receptor systems or that can induce more or less neurotoxicity is not clear; however, recent nonclinical data suggest that some combinations may be more neurotoxic than the individual components.

联合用药的潜在风险激活受体系统或强减轻神经毒性还未知。然而现有的非临数据显示一些联合用药的毒性大于任何的单独应用。

This paper enumerate nonorganic, organic pollutants and their toxicity produced by fossil fuel.

Toxic effects of 1,2,4-trichlorobenzene (1,2,4-TCB) on Scenedesmus obliquus were studied through investigating the growth, the content of protein and the content of chlorophyll.

以1，2，4-三氯苯(1，2，4-TCB)处理后斜生栅藻的生长状况、蛋白质含量、叶绿素含量、超氧化物歧化酶和过氧化物酶活性、丙二醛含量和培养液总有机碳含量的改变来检测1，2，4-TCB对斜生珊藻的毒性效应及其毒性作用机制。

Objective:To study on the effects of cooking oil fume on immune function and genetics of occupationally exposed staffs.

目的 ：探讨烹调油烟对职业接触人群的免疫毒性和遗传毒性。

He experiment proved that pre-implantation embryos are more sensitive than post-implantation ones, suggested TCDD may exert its effect before implantation, or at this process. 3. The toxicity of TCDD on the early embryo can be of omnifarious. It can strongly inhibit DCR, which represent mother toxicity; It cause un-synchronizated cleavage of pre-implanted zygote and pre-implanted embryo loss; It also decreases implantation sites in the uterus, and continued to effecting the uterus of pregnant mouse, cause the decreased number of fetus before birth. 4. TCDD exposure changed reproductive hormone level of pregnant mouse.

CDD对胚胎的毒性影响可能是多方面的：强烈抑制子宫蜕膜细胞反应，表现出典型的母体毒性；虽然没有影响胚胎转运速度，但造成着床前胚胎的丢失和发育不同步；早期染毒降低了第9天的胚胎着床数，同时使出生前第18天胚胎成活数继续减少。

The toxicity and the osteogenous ability on the surface of PCHA: the toxicity was examined by coculture with PCHA to record growth of cells with MTT method. The osteogenous ability was investigated by observation of the formation and growth of cells on the surface of PCHA bone cement.

PCHA毒性检测和表面细胞活性的观察：将PCHA浸出液与骨髓基质细胞共同培养，通过MTT比色描记细胞生长曲线，快速判定制孔剂添加后PCHA的毒性反应；将PCHA制成标准试件，与骨髓基质细胞共同培养，观察细胞形态和生长活性。

Polyaspartamides including PAEA(1), PAAPA, PADAOA and low molecular weight PAHA are markedly less toxic than poly and poly, however, PABA and higher molecular weight PAHA are slightly less toxic than poly.

与聚赖氨酸和PEI相比，PAEA（1）、PAAPA、PADEOA以及低分子量的PAHA具有明显低的细胞毒性；而PABA与高分子量PAHA的细胞毒性较聚赖氨酸略低。

ATA was found to exhibit more distinctive cytotoxicity toward human cervical squamous carcinoma HeLa cells than oleanolic acid, which suggested that the position of the carboxyl group significantly affects the cytotoxicity of oleanane-type pentacyclic triterpenes with a carboxyl group.
