不致病的

The result suggested that the variation was not associate with pathogenicity, but have some thing to do with cell culture or tissue appetency. The research is of high significance.

表明VP〓高变区大多数氨基酸的变异可能与病毒的致病性关系不密切，而与对细胞培养或组织的亲和性的关系更为密切。

The effecting mechanism of speleotherapy is still unknown for us in many aspects, but the larruping cave environment at least could reduce those environment factors and pathogens which make people sick or hypersusceptibility, and could filtrate contaminant and atmosphere fluctuation ,there no the same function in other circumstance.

洞穴医疗的作用机理在许多方面还不完全清楚，但特殊的洞穴环境至少在减少致病或过敏的环境因素、病源体及过滤污染物及气候波动等方面发挥了其它场所无法代替的作用，而洞穴医疗至少在下列几方面经临床记录而被证实有生物学上有利变化

Nowadays, research on the interrupt genes of such slow-growth mutants is seldom, either does not the research on the relationship between pathogenicity and hypha development.

目前，菌落生长缓慢突变体的研究和该类突变体相关基因的报道较少，菌丝生长与致病性的关系的研究也不系统。

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。

Many investigators have done a number of researches on IS and have found alot of possible nosogenetic factors, but the real etiology has not been clear yet.

近年来国内外学者对脊柱侧弯进行了大量的研究，发现了许多可能的致病因素，但其真正的病因仍不清楚。

Complementation assays in planta showed that either the deletion in the lipoprotein domain or in the transmembrane domain did not restore HR induction in tobacco and pathogenicity in rice to the hrcJ mutant.

功能互补结果显示，缺失脂蛋白结构域和跨膜结构域的hrcJ基因均不能恢复hrcJ突变体在烟草上的HR激发能力和在水稻上的致病性。

We detected the distribution of lipases in 35 Aeromonas isolates by PCR andphenotypic test using tributyrin as substrate. The positive rates were 100% and 83%,respectively. The lipase activity or associated genes could be detected in the two avirulentstrains, A. hydrophila W1 and A. hydrophila 4332. It suggested that lipase might not be animportant factor in pathogenic mechanism of A.

对本实验室保存的35株气单胞菌分离株进行了脂酶的表型检测和PCR检测，结果分别为83％和100％，特别是嗜水气单胞菌无毒株W1和Ah4332也能检测到脂酶活性或基因，表明脂酶在该菌的致病机制中不是决定性因子。

Males with KS1 who are fertile will pass the disease-causing mutation to all of their daughters and none of their sons.

可生育的男性KS1患者将把该致病突变传递给他的所有的女儿，不传递给他的任何一个儿子。

All these results indicate that the DNA variation process during the occurring process of adenocarcinoma may be: the stable DNA phosphate backbone in normal gastric mucosa change into unstable DNA phosphate backbone in intestinal metaplasia issue under affecting of pathogenic factors, and finally, DNA phosphate backbone is broken and re-forms a double stabilized phosphate backbones, which causes the occurring of adenocarcinoma.

这些结果提示胃癌的发生过程中DNA结构变化过程可能是：胃粘膜正常组织具有稳定的DNA磷酸骨架，在致病因素作用下发展为具有不稳定磷酸骨架DNA的肠化组织，最后组织DNA磷酸骨架断裂并重新形成稳定的DNA磷酸骨架，致胃癌发生。

There is also no animal model to understand how enterovirus spreads to the central nervous system.

由於尚无一个合适的动物模式，以致目前肠病毒71型的感染造成中枢神经的致病机转仍不清楚。

Do you know, i need you to come back

你知道吗，我需要你回来
