作者用固相酶免疫竞争法,对36例慢性特发性血小板减少性紫癜病(ITP)进行血小板表面IgG(PAIgG)和血清中血小板结合性IgG(PBIgG)的测定。结果发现:ITP患者的PAIgG增加,且PAIgG与血小板数之间呈负相关,血小板数在15×10~4/cmm以下的病例,29例中27例(93%)为阳性,而血小板数10×10~4/cmm以下者则全部阳性。PBIgG,血小板数在15×10~4/cmm以下的病例,20例中有10例
In this study, 36 patients with idiopathic thrombocytopenic purpura (ITP) underwent platelet surface IgG (PAIgG) and serum platelet-associated IgG (PBIgG) by solid phase enzyme immunoassay. The results showed that PAIgG was increased in patients with ITP, and there was a negative correlation between PAIgG and platelet count. In the cases with platelets below 15 × 10 ~ 4 / cmm, 27 cases (93%) were positive in 29 cases and platelet count was 10 × 10 ~ 4 / cmm the following were all positive. PBIgG, platelet count in 15 × 10 ~ 4 / cmm following cases, 20 cases, 10 cases
