title: Effects of alpha-tocopherol administration on red blood cell membrane lipid peroxidation in hemodialysis patients.
abstract: The result of vitamin E treatment in 19 uremic patients in chronic hemodialysis is evaluated. In particular, the levels of erythrocyte malonyldialdehyde (MDA) and vitamin E were determined, and the fatty acid composition of red blood cell (RBC) membrane before and after treatment with parenterally administered vitamin E. A decrease of RBC MDA levels, an increase of RBC vitamin E concentrations, and a decreased saturated fatty acid to unsaturated fatty acid ratio were found after treatment with vitamin E. There was a statistically significant increase of the packed RBC volume.
