To date, quite a little research only recognized CRP as a common plasma protein to investigate whether CRP could induce inflammation in endothelium, but ignored special structure and crucial physiological function of CRP.

目前，相当多研究仅仅把CRP作为一种普通血浆蛋白来讨论其能否诱导内皮系统炎症发生，忽视了CRP的特殊结构和其重要的生理功能，而如果探讨CRP在动脉粥样硬化中形成起保护性作用还是破坏性的作用，就有必要充分考虑CRP的结构和生理功能。

Objective To expiore the pathogenic mechanism of hemorrhagic fever with renal syndrome.Methods 2-3 days old inbred Balb/C suckling mice were inoculated intracerebrally with tissue suspension of soft parate petechia of HFRS patients and the HFRS virus RNA was tested in brain, lung and kidney tissues of sucking mice by nested PCR.

目的 探讨肾综合征出血热的发病机理方法 2～3天的近交系Balb/C乳鼠，脑内接早期HFRS重症患者软腭粘膜出血点组织悬液，用套式聚合酶链式反应检测乳鼠脑、肺及肾组织中的HFRS病毒RNA。

The former, intracranially complements patients some factors, most frequently with TH gene to compensate scanty of intrastriatal DA and improve the symptoms of the patients, while have little resistance to the progressive degeneration of dopaminergic neurons; The latter provide variety of neurotrophic factors, most specific being the glial cell-line derived neurotrophic factor , to protect the residual DA neurons in the nigrostriatal system from further pathogenic injuries, while have little benefit to those DA neurons with irreversible damage, and them cannot offset the already-existing symptoms.

前者是给宿主脑内补充某些因子，主要是DA合成过程中的限速酶TH基因，以补充纹状体内DA含量的不足，减轻患者的症状，但对DA能神经元的进行性退变没有治疗效果；后者则是提供各种神经营养因子其中最具特异性的为GDNF，以保护黑质一纹状体系统内剩余的DA能经元免受病因的继续损害但对已发生不可逆性损害的DA能神经元并无拯救作用，无法消除已出现的症状。

The results showed that typical FMD clinical signs produced in cattle inoculated intradermally with pathogenic FMDV after 48 h. The 3ABC antibody produced in these cattle were detected to be suspicious on the 3rd day, 3ABC antibody in the 1/4 cattle were positive on the 5th day, and the 4/4 were positive on the 8th day post virus inoculation; In 10 co-housed cattle (breeded with artificially infected pigs and sheep separately), no 3ABC antibody were detected on the 7th day and percent of positive 3ABC antibody was only 30%(3/10) on the 15th dpi (4/10 had clinical symptom).

实验表明，4头牛在舌面接种感染FMDV 48h后全数发病，第3天即出现可疑的3ABC抗体，第5天检测到阳性的3ABC抗体，至第8天3ABC抗体全部为阳性；10头同居牛（分别与接种感染猪和羊同居）在同居第7天时未检出3ABC抗体，在同居第15天时，3ABC抗体阳性率仅为30%；肌肉接种病毒羊3ABC抗体产生时间与接种病毒牛一致。

Koch publishes his Methods for the Study of Pathogenic Organisms in which he describes his success with solidified culture media.

科赫在病原生物研究一文中发表了他的方法，他在其中将自己的发明称为固体培养基。

The discovery of penicillin so that the people of pathogenic micro-organisms from infection caused by various diseases are no longer at a loss, and thus the development of a large number of β-lactam antibiotics, for the protection of human health have made great contributions to the.

青霉素的发现使人们对由病原微生物感染而引发的各类疾病不再束手无策，并由此发展了大量的β-内酰胺类抗生素，对保护人类健康作出了巨大贡献。

The liqase was positively controlled by HAI and AI-2 to some extent. The lecithinase was negatively controlled by HAI-1, and the hemolysin was negatively controlled by both HAI-1 and AI-2. Special primers of luxS gene were designed from the luxS gene sequence of V. harveyi obtained from the GenBank, and the gene was amplified from a pathogenic strain V. harveyi VIB645 by PCR. The luxS gene was cloned to a cloning vector pUC, and was sequenced. It was found that the open reading frame is 519 bp. The similarity of the luxS gene from V. harveyi VIB645 to the published sequence of V. harveyi strain in GenBank was only 90%.

从GenBank中获取哈维氏弧菌中编码AI-2合成酶的luxS基因序列设计一对特异性引物从哈维氏弧菌VIB645中PCR扩增luxS基因，将luxS基因克隆于pUC载体并测序，发现其与GenBank中已发表的哈维氏弧菌的luxS基因序列相似性为90%，证明LuxS/AI-2系统在哈维氏弧菌不同的菌株中的具有一定的特异性，推测LuxS/AI-2系统可能与哈维氏弧菌的致病性或发光现象有关。
