The results of examining the mechanisms of development of neurogenic visceral abnormalities induced by the body's extreme exposures, search for modes of its pharmacological correction are presented. Experiments have provided evidence for that the neutropic agents recovering the functional activity of the sympathetic nervous system, normalizing energy and plastic exchange have a positive effect in the treatment of the cardiovascular and gastroduodenal diseases which are caused by a neurogenic agent. A basically new approach to treating peptic ulcer, coronary heart diseases, and myocardial infarction is proposed depending on the stage of a disease.

Neurogenic gastric lesions in rats were induced by a combination of immobilization and 3-hour electrostimulation. Neurogenic cardiac injury in rabbits were induced by 3-hour electrical stimulation of the aortic arch. Thereafter the activation of lipid peroxidation in the stomach and heart was recorded. There was an increase in MDA levels and a decrease in antioxidative enzyme activity in the tissues and serum (catalase and superoxide dismutase). The administration of the neurotropic drugs which restore the activity of the sympathetic nervous system (L-DOPA, aethimizol, fenibut and piracetam) was shown to normalize the processes of lipid peroxidation.

Neurogenic gastric lesions in rats were induced by combination of immobilization with 3-h long electrostimulation. After this stress a distinct decrease of noradrenalin and creatine phosphate content and then the activation of lipid peroxidation (LPO) in the stomach tissue was recorded. If the stress treatment was preceded by application of piracetam and fenibute, gastric tissue trophic was protected by way of prevention from a decrease of the content of noradrenalin, creatine phosphate and the activation of LPO.

It was found that 3 hours after electrostimulation of the immobilized rats there was observed in addition to destructive lesions in the gastric mucosa a significant decrease of noradrenaline, dopamine, DOPA, homovanillic acid and creatine phosphate levels in the brain tissue involving the hypothalamus and the midbrain surrounding it. The use before the extreme impact of neurotropic agents blocking transmission of the damaging impulses from the site of stimulation of reflexogenic zones through the central adrenergic synapses which activate genome in the nerve cell or prevent depletion of catecholamine stores and disturbance of energy formation processes in the brain tissue protects against the development of neurogenic damage of the stomach.
