作者对19例感染性心内膜炎病人(病原包括绿色链球菌、D群肠球菌、金黄色葡萄球菌等)进行循环免疫复合物和单核吞噬细胞系统功能测定的跟踪研究。用葡萄球菌结合试验检测病人体内的循环免疫复合物(CIC);IgG致敏红细胞的Fc依赖性清除试验测定病人体内单核吞噬细胞系统的功能。葡萄球菌结合试验采用病人血清,以5%聚乙二醇沉淀、重溶,加入热杀、福马林固定、具有A蛋白的葡萄球菌孵育,然后把这
The authors followed 19 patients with infective endocarditis (pathogen including Streptococcus agalactiae, Group D enterococci, Staphylococcus aureus, etc.) for circulating immune complexes and mononuclear phagocytes function of the system of tracking studies. Circulating immune complexes (CICs) were measured in patients with staphylococcal binding assays; the Fc-dependent clearance assay of IgG-sensitized erythrocytes measured the function of the mononuclear phagocyte system in the patient. The staphylococcal conjugate assay used patient serum, precipitated with 5% polyethylene glycol, resuspended, incubated with heat, fumarate fixed, staphylococci with protein A and then incubated with
