[Effect of pro- and antioxidant food factors on macrophage oxidative metabolism].

The effects of vitamin E deficiency and excess polyunsaturated acids in the diet on luminol-dependent chemiluminescence were studied in Aug-Lac rats. It was chown that experimental prooxidant regiments led to the increase of oxidative metabolism in macrophages stimulated by opsonized zymozan. Vitamin E deficient regimens decreased superoxide dismutase activity of macrophages. In vitro DL-alpha-tocopherol and the synthetic antioxidants BHT and BHA inhibited chemiluminescence of macrophages. Arachidonic acid activated macrophages and induced the formation of oxygen radicals.
