| الوصف: | OBJECTIVE. Study the effect of a single and multiple administration of hyperbaric oxygenation (HBO) in the therapeutic regime on the processes of lipid peroxidation (LPO) and enzyme of antioxidative defense in phylogenetically various structures of the brain in the period of the immediate and remote aftereffect of expositions. MATERIALS AND METHODS. Experiments were carried out on 87 nonlinear white male rats weighing 180-230 grams. Hyperbaric oxygenation was conducted by medical oxygen in the experimental pressure chamber in the “mild” mode (2 ata, 50 min isopression), 1 session per day in the morning. The study was carried out after 1, 5, 10 sessions, in 5 and 10 days after 1 session and in 5 days after 5 sessions of HBO. The content of malondialdehyde (MDA) was determined in the brain stem, cerebellum and large brain hemispheres. The state of an enzyme element of antioxidant defense was evaluated by superoxide dismutase (SOD) and catalase. RESULTS. It was found that exposure to oxygen under high pressure caused increased intensity of LPO processes in the brain that progresses from 1 to 5 sessions. While MDA changes in the brain stem were detected later than in the hemispheres and cerebellum. LPO intensification in the brain proceeded against the background of increased activity of SOD. After 10 sessions of HBO LPO intensity decreased that was confirmed by reduced MDA content and SOD activity in examined brain tissue. Catalase activity reduced in the stem after 5 sessions and increased in the cerebellum and hemispheres after 10 sessions of HBO. Aftereffect of 1 HBO session was characterized by persistent increase in MDA concentration in the brain regions, detected in 5 and 10 days after exposure and was accompanied by increased SOD activity against the background of reduced catalase activity. In 5 days after 5 sessions the increase in MDA content and SOD activation was observed only in the tissue of the cerebral hemispheres. DISCUSSION. The use of HBO in the mode 2 ata, 50 min stimulates reactions of free ... |
