Effect of vitamin E deficiency on oxidative metabolism and antioxidant enzyme activity of macrophages

In AUG rats, deprived of vitamin E for 90 days, we noted a 3-fold increase of kinetic parameters of luminol-dependent chemiluminescence of macrophages, stimulated with opsonized zymosan, superoxide dismutase activity decrease and increment of plasma membrane lipid bilayer microviscosity, which was estimated by fluorescent probe pyrene eximerization method. Vitamin E deficiency did not affect glutathione peroxidase and glutathione reductase activities of macrophages.
