致病

The results show that in the processes of shake 2out and finishing , molding , sand preparation , pouring , melting and coremaking , all the dusts are silica2 containing dust . The respirable dust （ 5 μm） occupies as high as 6915 %~ 78 %. Silica2containing dust in foundry air is not packed by Al. It indicates that silica dust in foundry air is fresh and highly pathogenic.

结果表明，清理、造型、配砂、制芯、熔化和落砂等工序游离SiO2 含量均超过10 %，分散度小于5μm的可吸入性粉尘偏高（6915 %~78 %），空气中矽尘没有Al 的包裹，是新鲜的粉尘，致病性强。

The distinct cytopathological characters in the cells infected by different isolates were not observed, and more research on the pathogenic variation should be worked on.

RDV不同分离株侵染寄主植株的细胞病理特征无显著差异，对其致病性的差异需进一步研究。

Quinolones associated AIN cases are more than before. DAIN has no significant features. Monitoring the urinary glucose and renal function may contribute to the early detection of DAIN.

DAIN临床症状缺乏特异性，用药后监测尿糖及肾功能的变化有助于早期发现DAIN，综合分析临床特点有助于判断致病药物。

Objective of this study was further to definitize variety and biology Characteristics of pathogens of soybean root rot.

Phaeohyphomycosis is an entity caused by local infection in superficial tissue, skin, cornea, subcutaneous tissue and even systemic infection with a large group of dematiaceous fungi. It is important to promptly diagnose and exactly manage this disorder, otherwise, fatal disseminated phaeohyphomycosis may occur.

暗色丝孢霉病是由一大组条件致病性暗色真菌引起的浅表组织、皮肤、角膜、皮下组织甚至系统性感染，及时、正确的诊治非常重要，否则可导致致命的播散性暗色丝孢霉病。

sick euthyroid syndromeshould be often found in patients with critical trauma,but it is commonly confused ses with retention of fluid in third space after fluid resuscitation or with lowed colloid osmotic pressure as result of hypoproteinemia in the clinic.serious ses is presented an edema of face and all over,non blood fluid draining out of the needle hole,the wound not healing desiredly with fluid oozing unexpectedly,or pleural effusion on both sides,or pericardial effusion.the pathogenesis of ses is incompletely understood.the inflammatory cytokines are generally accepted as an important pathogenic factor of ses.

甲状腺功能正常性病变综合征（sick euthyroid syndrome，ses）在危重创伤患者中并不少见，严重者表现为颜面及全身肿胀，针眼可见持续的非血性液体流出，伤口渗液较多不易预期愈合，双侧胸腔积液或心包积液等。临床上常与液体复苏后的第三间隙液体潴留、低蛋白血症致胶体渗透压降低等的临床表现相混淆，很容易被忽略。其发病机制还不十分清楚，众多的研究首先考虑的致病因素是炎性因子。

The dimorphic transition of yeast and hyphal forms is one of most determinants in Candida albicans for its pathogenicity. This transition is regulated by several signal transduction pathways.
