[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.

[The mechanisms of the neuroprotective action of carbonate mineral baths in ischemic brain lesions].

Effects of Arzni effervescent mineral baths (EMB) on brain tissue metabolism were studied on white rats (normal controls and those with transitory cerebral ischemia). It was found that EMB prevent ischemia-related disorders of phospholipid and adeninnucleotide pools, promote an increase in vasoactive prostaglandins in brain tissue, shifts in catecholamines concentrations in the hemispheres and hypothalamus, inhibit the activity of monoaminoxidase and absorption of 3H-noradrenaline by brains sections. Mechanisms of neuroprotective action of Arzni EMB in cerebral ischemia are considered.
