测定了３１例急性脑梗塞患者红细胞Ｃ３ｂ受体花环率（ＲＢＣ—Ｃ３ｂＲＲ）和红细胞免疫复合物花环率（ＲＢＣ—ＩＣＲ）以及可能影响红细胞免疫粘附（ＲＣＩＡ）功能的血清脂质过氧化物（ＬＰＯ）、超氧化物歧化酶（ＳＯＤ）。结果表明，急性脑梗塞患者ＲＢＣ—Ｃ３ｂＲＲ明显降低，而ＲＢＣ—ＩＣＲ明显增高；血清ＳＯＤ含量减少，ＬＰＯ明显增高。ＲＢＣ—Ｃ３ｂＲＲ降低与血清ＬＰＯ增高呈显著负相关，与ＳＯＤ呈正相关。上述结果说明红细胞免疫功能降低与体内自由基代谢改变有关。
The RBC-C3bRR and RBC-ICR of erythrocytes in 31 patients with acute cerebral infarction and serum lipid peroxides (RBC-ICR), which may affect the function of erythrocyte immune adherence (RCIA) LPO), superoxide dismutase (SOD). The results showed that patients with acute cerebral infarction RBC-C3bRR significantly decreased, while RBC-ICR was significantly increased; serum SOD decreased, LPO was significantly higher. The decrease of RBC-C3bRR was negatively correlated with the increase of serum LPO, but positively correlated with SOD. The above results indicate that the decrease of erythrocyte immune function is related to the change of free radical metabolism in the body.
