abstract：:Peroxidation of intact human erythrocytes by t-butylhydroperoxide (tBHP)) was studied. By incubation of the erythrocytes with 1 mM tBHP, reduced glutathione (GSH) was exhausted within 1 min, and tocopherols (Toc) and phospholipids (PL) decreased to nearly their lowest levels (in this study) within 5 min. The rate of d...
