摘要：
Background: Previously, we reported an increase in expressions of mRNA of Cu/Zn-superoxide dismutase (SOD) in leukocytes of hemodialysis (HD) patients, and speculated that the increase is associated with oxidative stress on the leukocyte membrane due to the HD process. Methods: Expressions of Cu/Zn-SOD mRNA in leukocytes, contents of plasma SOD, and malondialdehyde (MDA) in leukocyte and erythrocyte membranes, respectively, were examined in 25 HD patients and 14 healthy volunteers. These were also determined after using a vitamin E-coated dialyzer (VE dialyzer) for 4 weeks. Results: All values were significantly higher in HD patients. A significant correlation was found between leukocyte Cu/Zn-SOD mRNA expression and membrane MDA. After using the VE dialyzer, all values were significantly lowered, showing a significant correlation between changing rate of leukocyte Cu/Zn-SOD mRNA expression and membrane MDA. Conclusion: In HD patients, oxidative stress is generated on the leukocyte membrane, and the level of Cu/Zn-SOD mRNA in leukocytes can be a useful oxidative stress marker. Copyright (C) 2011 S.
