title: Effects of blood storage on red cell antioxidative systems.
abstract: The activities of the antioxidative enzymes superoxide dismutase, catalase and glutathione peroxidase and the concentration of reduced glutathione were determined in CPD-adenine blood stored at 4 degrees C for up to 20 days. Superoxide dismutase activity was found to be significantly reduced with storage beyond 10 days. The clinical significance of this finding is discussed.
