外毒素

Objective To evaluate the toxic effects of staphylococcus aureus exotoxins and neutrophils on retinal pigment epithelium cells.

目的 观察金黄色葡萄球菌外毒素及中性粒细胞对视网膜色素上皮细胞的毒性作用。

Both staphylococcus aureus exotoxins and neutrophils can damage the RPEC by inducing necrosis, and their function had synergetic effect.

金黄色葡萄球菌外毒素对RPE细胞具有毒性作用，其机制主要以细胞坏死的方式进行。

Using immuno-histochemical, tissue cultural and immuno-electron microscopic methods, based on nerve-endocrine-immune net, the dynamic changes of 4 brain-gut peptides and 6 inflammation factors of excised saccalus rotunds of rabbit stimulated by germs, LPS, exotoxin were observed.

本研究以神经-内分泌-免疫网络学说为依据，运用免疫组织化学的方法，结合组织培养技术、免疫电镜技术等，对离体兔圆小囊受到大肠杆菌等4种细菌、内毒素、外毒素等抗原刺激后，其组织内的4种脑肠肽和6种炎症相关因子表达量的动态变化进行了系统观察研究。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
