Abstract
Experiments on rats showed that the individual resistance of the body to acute hypoxia is of decisive importance in the early recovery period after mechanical craniocerebral trauma. Antihypoxant ethomersol administration (25 mg/kg, 3 days, intraperitoneally) following trauma decreased behavioral impairments in rats with different levels of resistance to acute hypoxia, restored the structure of individual behavior, and prevented metabolic disturbances in the brain. Monotherapy of consequences of craniocerebral trauma with antidepressant pyrazidol (1 mg/kg) produced an anxiolytic effect in animals highly resistant to hypoxia and activating effect on low resistant animals. Treatment with bemithyl, an antihypoxant of benzimidazole structure, in a dose of 25 mg/kg produced a cerebroprotective effect and normalized individual behavioral characteristics, parameters of energy metabolism, and state of the antioxidant system in the brain of highly and low resistant rats. The effect of bemithyl was most pronounced in highly resistant animals. During combined treatment, pyrazidol and bemithyl had an additive effect in animals of both groups. They normalized behavioral reactions and prevented the development of metabolic disturbances in the brain.
