目的探讨红细胞免疫功能与动脉硬化性脑梗塞的关系。方法采用免疫测定法检测２０例脑动脉硬化患者、３８例动脉硬化性脑梗塞患者、３５例健康对照者的红细胞 Ｃ３ｂ受体花环率（ＲＢＣ－Ｃ３ｂＲＲ）和红细胞免疫复合物花环率（ ＲＢＣ－ ＩＣＲ）。结果脑梗塞 ＲＣＢ－Ｃ３ｂ ＲＲ低于正常对照组（ Ｐ＜０．００１），而ＲＢＣ－ＩＣＲ高于正常对照组（Ｐ＜０．００１），红细胞Ｃ３ｂ受体活性降低与脑梗塞灶大小呈负相关性（ｒ＝－０．６５， Ｐ＜０．０１）。结论红细胞免疫功能与动脉硬化性脑梗塞发病有关。
Objective To investigate the relationship between erythrocyte immune function and arteriosclerotic cerebral infarction. Methods RBC-C3bRR and RBC-ICR of 20 patients with cerebral arteriosclerosis, 38 patients with arteriosclerotic cerebral infarction and 35 healthy controls were detected by immunoassay. ). Results The RCB-C3b RR of cerebral infarction was lower than that of the normal control group (P <0.001), while the RBC-ICR of cerebral infarction was higher than that of the normal control group (P <0.001) Correlation (r = -0.65, P <0.01). Conclusion Erythrocyte immune function is related to the pathogenesis of arteriosclerotic cerebral infarction.
