致病

In infected animals , the reduced viral diversity leads to loss of neurotropism and an attenuated pathogenic phenotype .

在受感染的动物，病毒多样性的减少导致的神经性和损失的减毒致病型。

PRV is more advantageous for the research of the production and distribution, neurotropism and pathogenesis of alpha herpesvirus and evaluation of immune response and new vaccine. Therefore, PRV has interested the researchers and become an excellent model system for herpesvirus biology.

因此，PRV对于研究α—疱疹病毒在自然宿主中的增殖与分布、神经嗜性、致病机理、免疫反应及新型疫苗效力评价等方面具有很大的优越性，颇受疱疹病毒研究学者的青睐，并成为α—疱疹病毒研究的良好模型。

It contains noninfectious killed virus, but merely alerts the body to the threat of the virus.

它的主要成份是一些已被完全杀死的流感病毒，所以绝不会致病。

A formalin-inactivated RSV vaccine was used to immunize children and elicited nonprotective, pathogenic antibody.

使用福尔马林灭活病毒疫苗给婴幼儿进行免疫接种，无法产生保护性抗体，而导致了致病性抗体的生成。

RESULTS: The main causes of disease were peripheral nerve palsy result from diabetes (26%) and nonspecificity inflammation (17%).

结果：外展神经麻痹的主要病因有糖尿病性外周神经麻痹（26%）；非特异性炎症（17%），虽然经一系列的检查（如：CT、DSA、MRI、颈内血管超声，糖耐量筛查、鼻咽部活检、腰穿等）仍有17%的患者不能明确致病原因。

ObjectiveTo investigate the effect of nonstructural protein 4B of hepatitis C virus on LO2 cell proliferation and expression of cyclinD1 in vitro.

These results provide scientific evidence for the comprehensive understanding of nosogenesis of cigarette.

这些研究结果有可能为全面认识香烟致病机理提供一定的科学依据。

The authors further propose that it is of great value to study of the nosogenesis by dusts on the nanometer size.

故提出在纳米级别上研究粉尘致病机理是非常有价值的。

This result will help studying the function of 3a and 7a protein and provide a method to study the nosogenesis mechanism of SARS-CoV.

此结果对进一步研究3a和7a的功能以及对SARS-CoV的致病机制的进一步研究有一定意义。

From August2004 to August 2005. Results: There were only 40 patients, 44.1% ofthe 89 patients had definite nosogenesis.

结果：全组有明确致病因素者40人，占44.1%；绝大多数患者无明确病因。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
