观察６２例慢性肾衰患者ＲＢＣ－ＳＯＤ活性、ＲＢＣ－ＬＰＯ浓度和红细胞免疫功能，结果表明，肾衰患者ＲＢＣ－ＳＯＤ活性较对照组降低（Ｐ＜０．０１），ＲＢＣ－ＬＰＯ浓度较对照组明显升高（Ｐ＜０．０１）；红细胞Ｃ３ｂ受体花环率（ＲＢＣ－Ｃ３ｂＲＲ）、红细胞免疫粘附促进因子（ＲＦＥＲ）活性较对照组明显降低（Ｐ均＜０．０１），红细胞免疫复合物花环率（ＲＢＣ－ＩＣＲ）、红细胞免疫粘附抑制因子（ＲＦＩＲ）活性较对照组明显升高。ＲＢＣ－ＳＯＤ活性与ＲＢＣ－Ｃ３ｂＲＲ呈正相关，与ＲＢＣ－ＩＣＲ呈负相关，ＲＢＣ－ＬＰＯ浓度与ＲＢＣ－Ｃ３ｂＲＲ呈负相关（Ｐ＜０．０１），与ＲＢＣ－ＩＣＲ浓度呈正相关（Ｐ＜０．０５），提示肾衰患者红细胞内抗氧化能力降低，脂质过氧化反应增强，红细胞免疫粘附功能降低，红细胞免疫粘附调节功能紊乱；红细胞ＳＯＤ活性、红细胞ＬＰＯ浓度能直接影响ＲＢＣ－Ｃ３ｂＲＲ的活性，进而影响红细胞清除免疫复合物的能力，与红细胞免疫功能的强弱有直接关系。
RBC-SOD activity, RBC-LPO concentration and erythrocyte immune function were observed in 62 patients with chronic renal failure. The results showed that RBC-SOD activity in renal failure patients was lower than that in control group (P <0.01) (RBC-C3bRR) and erythrocyte immune adherence promoting factor (RFER) activity of erythrocytes were significantly lower than those of the control group (all P <0.01). The ratio of erythrocyte immune complex RBC-ICR and RFIR were significantly higher than those in control group. The RBC-SOD activity was positively correlated with RBC-C3bRR, negatively correlated with RBC-ICR, RBC-LPO concentration was negatively correlated with RBC-C3bRR (P <0.01), and positively correlated with RBC- 05), suggesting that renal failure in patients with erythrocyte antioxidant capacity decreased, lipid peroxidation increased erythrocyte immune adherence decreased erythrocyte immune adhesion regulation dysfunction; erythrocyte SOD activity, erythrocyte LPO concentration can directly affect the RBC-C3bRR Activity, and thus affect the ability of red blood cells to clear immune complexes, and the strength of the immune function of red blood cells are directly related.
