对３０例慢性肾衰（ＣＲＦ）患者作血清及红细胞中超氧歧化酶（ＳＯＤ）、血清丙二醛（ＭＤＡ）及多种微量元素的测定，结果显示：ＣＲＦ患者血清ＭＤＡ水平显著升高，血透和非透析组血清锌的下降与红细胞ＳＯＤ活性下降正相关，腹透组血清铝的升高与红细胞ＳＯＤ活性下降负相关，血透患者透析后ＳＯＤ活性较透析前明显升高。
In 30 cases of chronic renal failure (CRF) patients with serum and erythrocyte superoxide dismutase (SOD), serum malondialdehyde (MDA) and a variety of trace elements determination results showed: CRF serum MDA levels were significantly elevated, blood The decrease of serum zinc in both dialysis and non-dialysis groups was positively correlated with the decrease of SOD activity in erythrocytes. The increase of serum aluminum in PD group was negatively correlated with the decrease of SOD activity in erythrocytes. The activity of SOD in hemodialysis patients was significantly higher than that before dialysis.
