为了解自身心肌反映性抗体(HRA)在克山病人体内存在的状态和意义,探索克山病机理与免疫的关系,本文采用免疫荧光染色技术对4例克山病患者尸体的心肾组织IgG沉着物做了检测。证明在4例克山病病人心肌纤维上和肾小球内都查到有IgG沉积物,表明很可能参于克山病的继发性免疫病理过程,致使患者病程反复迁延,终生不愈。此认识有待进一步研究证实。 In order to understand the status and significance of myocardial reactive antibody (HRA) in Keshan patients and to explore the relationship between Keshan disease and immune system, immunofluorescence staining was used to detect the expression of cardiac and renal tissue in 4 cases of Keshan disease Sediment made a test. Proved in 4 cases of Keshan disease in patients with myocardial fibrosis and glomerular were found in the IgG deposits, suggesting that it is likely to participate in Keshan disease secondary immune pathology, resulting in patient duration of repeated protracted, unhealed lifetime. This understanding needs further study confirmed.
