链球菌溶血素

A specific antigen from group A streptococcal cell membrane and 1% PHA used as a stimulant to test the peripheral blood lymphocyte adherence inhibition percent and procoagulant activity in 30 cases of active rheumatic carditis, 24 cases of inactive rheumatic carditis and 38 cases of normal controls.

用A组乙型溶血链球菌特异性菌膜抗原和1%植物血凝素作为刺激物，分别测定38例健康对照组，30例风湿性心脏病风湿活动组，24例风湿性心脏病静止组的外周血淋巴细胞贴壁抑制百分率（Lymphocyte adherence inhibition percent， LAIP）和促凝血活性（Procoagulant activity， PCA）。

Patients typically have an elevated anti- streptolysin O titer.

患者抗链球菌溶血素 O 滴度显著增高。

But we have seldom found the reports about it in China; So writer summarized some literature more than twenty years; name,classification and family of hemolysin have been written, especially three of representative species:α-toxin, Streptolysin O and HlyA; Nowaday, A relationship between the hemolysin and pathopoiesis of bacterium is obvious.

另外，细菌溶血素的英文命名并不统一，检索时容易造成漏检或误检；通过查阅大量英文文献资料，归纳汇总近20年报道的溶血素研究进程；该文详细列出了细菌溶血素名称、分类以及各溶血素家族列表。并且分别介绍了其中三种典型的穿孔毒素：葡萄球菌α-毒素、链球菌溶血素-O、埃希氏大肠杆菌溶血素HlyA。

Objective To evaluate diagnostic value of anti-deoxyribonuclease B microtitration test in rheumatic fever. Methods Anti-DNase B antibodies of 87 patients with acute rheumatic fever and 202 rheumatic heart disease patients with rheumatic activity were detected with anti-DNase B antibody microtitration test,and compared with antistreptolysin "O" test.

目的 评估A组溶血性链球菌感染的血清学测定方法对诊断风湿热的临床价值方法采用抗DNA酶B微量法和自制试剂测定急性风湿热87例、活动期风湿性心脏病202例病人血清的抗DNA酶B抗体，与抗溶血素O抗体对照研究。

Methods Concanavalin A, wheat germ agglutinin, Sambucus nigrn agglutinin, Ricinus communis agglutinin-I and phytohemagglutinin were labeled with horseradish peroxidase by an improved sodium periodate method, and the synthetic HRP-agglutinins were used for determination of the expression levels of polysaccharide in common α-hemolyic streptococcus and in the α-hemolyic streptococcus after space mutagenesis.

采用改良的过碘酸钠法将辣根过氧化物酶分别标记在刀豆凝集素、麦胚凝集素、接骨木凝集素、蓖麻凝集素I及植物血凝素上，合成HRP-凝集素，检测普通型α-溶血性链球菌及太空型链球菌菌体内多糖分子的表达水平。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
