抑制作用的

The results show that Cd2+ for Pistia stratiotes and Myriophyllum spicatum L root-like effects of microbial flora with the microorganism or physiological groups, training time and Cd2+ concentration varies; Micro-organisms under Cd2+ stress would have two distinct effects: First, the growth of micro-organisms are not suited to reduce the number or extinction; Second, the growth of micro-organisms adapt to an increase in the number or the accumulation.

结果表明，Cd2+对大薸和穗状狐尾藻根系微生物的影响随微生物区系或生理类群、培养时间和 Cd2+浓度的不同而不同；受重金属镉胁迫后微生物会产生两个明显的效应：一是不适应生长的微生物数量会减少或灭绝；二是适应生长的微生物数量会增加或积累，在低浓度下，重金属对微生物数量一般有刺激作用，而在高浓度下一般为抑制作用，也有表现出刺激作用。

objective to investigate the inhibition mechanism of nanoapatite on the human hepatocelluar carcinoma.methods stable and single-dispersed nanoapatite were synthesized with sol-gel method.nanoapatite were surveyed by zataplus and tem.their effect on the bel-7402human hepatoma cell lines was investigated by the mtt methods,and the mechanism was studied from changes in ultrastructure.results the result showed that inhibition of nanoapatite on the bel-7402human hepatocellular carcinoma cell lines was presended obviously in vitro.conclusion nanoapatite entered into cancer cytoplasm,and cancer cells result in oncosis.

目的 探讨纳米磷灰石的抑癌机制。方法利用sol-gel法制备出稳定单分散的纳米磷灰石体系，应用粒径电位仪和透射电镜对纳米磷灰石进行表征；采用mtt比色法研究纳米磷灰石对细胞系bel-7402人肝癌细胞的作用；从超微结构的改变研究其作用机制。结果实验结果表明，纳米磷灰石在体外对bel-7402人肝癌细胞具有明显的抑制作用。结论通过进入到癌细胞内，导致癌细胞胀亡。

In addition, it must also evade immune clearance. Elimination of H. pylori by phagocytes is inefficient because H. pylori exhibits several virulence factors to evade opsonization, retard phagocytosis, and disrupt membrane trafficking and phagosome maturation after internalization of the microorganism.
