[Effect of low intensive helium-neon laser on superoxide-producing and methemoglobin-restoring activity of cytochrome b558III of red cell membranes in experiment].
It is established that low-energy He-Ne laser without changes from the side of NADPH-dependent superoxide-producing activity of b558III cytochrome isolated from erythrocytic membranes (EM) promotes b558III activity decrease in EM. The level of metHb-restoring activity increases during irradiation by He-Ne laser. The form of optical spectrum of b558III cytochrome absorption in the visible spectrum area does not undergo essential changes after laser irradiation while optical spectral index (A412/A530) is reduced a little. It is supposed that in the basis of photochemical mechanisms of He-Ne laser protector action in oxidative stress lays its ability to increase EM stability due to a decrease of superoxide-producing and an increase of metHb-restoring activity of b558III cytochrome
