The main factor of pathogenesis of disease at emotional stress is an accumulation in fabrics of free radicals, those results in lipid peroxidation of membranes of different cages, especially neurons of cerebrum. Thus in central nervous system especially in the structures of limbic-reticular complex, there are changes of sensitiveness of neurons to neuromediator and oligopeptidis. It, in the turn, leads to forming of stagnant emotional excitation in central nervous system, which results in proof violation of mechanisms of self-regulation of arterial pressure, update of shells of mucous tunic gastrointestinal tracts and increase of penetrating of connective tissue membranes in different organs. Emotional stress results in generalized distribution of sympathetic and parasympathetic excitations of, which shows up in one the violation of activity of the cardiac-vascular system, in other - gastrointestinal tracts. In the conducted researches it is shown that a those organ or system, which, after imagination of patient, is most impressionable and most essential for vital functions, suffers under act of the protracted stress. Opinion is expressed also that the choice of organ-target depends on the structures of crusts, which determine an optimum efferent way for the output of emotions, caused stress, on periphery. To research psychological features of children´s personality with duodenal ulcer. 36 children 10-18 years of age are inspected. The program of medical inspection included: interview with specially developed questionnaires, genealogy research, research of psychological type of personality by the test of Ayzenko and inspection of character using A.E. Lychko pathological characteristic questionnaire. With the purpose of determination of endoskopic and functional changes from the side of overhead departments of digestive fiberscope was executed by fiberscope with determination of endoskopics criteria of presence of gelikobakter infection and shield biopsy of mucus shell of stomach and duodenum by generally accepted rules of taking with next preparation of impression smear, staining and bacterioscopy. Simultaneously conducted intragastric acidity analysis with the study of secretory and alkalescence functions of stomach after the difference of values of acidity in a body and antrum. By the help of questionnaire data was established that family´s psycho-traumatic situations had 65 % of children. A genealogical analysis revealed that 75 % of children are burdened with inherited inclination. Emotional deprivation is aftereffect of child alienation from emotionally meaningful people in a responsible personality formation period that predetermines the deficit of intercourse skills. The broken emotional connection in babyhood leads to developing of duodenal ulcer before time, burdened with inherited anamnesis and differs with heavier, frequently relapsing clinical course, complications and severe pain syndrome. When emotional copulas were broken before pubertal period than clinical course of duodenal ulcer was sparer. In a severe period of illnesses prevailed psychasthenia and labile accentuation of character, introvertive mode of behavior, emotional instability. Discovered psychosomatic features of duodenal ulcer clinical course dictate the necessity in development of differentiated treatment programs and prophylaxis of this pathology.
