[Correction of altered serotonin exchange in adolescents with functional disorders of digestive system].

With the purpose of search the ways of improvement treatment of functional pathologies of the system of digestion an author is studied the concentration and the role of serotonin in 180 adolescents. Got results of serotonin receptors 5HT1 agonists were used for patients with paroxysms of abdominal pain mainly at neurocirculatory disfunction and migraine.

[Clinical characteristics of the functional dyspepsia in adolescents].

The author has studied clinical peculiarities of the functional dyspepsia in 92 adolescents. It was established that functional dyspepsia takes first place in the list of the digestive system diseases. There were different vegetative disorders in all patients with functional dyspepsia.

[Role of gastrointestinal hormones in pathogenesis of functional diseases of the digestive system in adolescent].

The author studied concentration of gastrin and holecistokinin in 68 adolescent with functional disease of the digestive system and vegetative dysfunctions. Considerable increase was established in the level of blood plasma gastrin in patients with gastroesophageal reflux and functional dyspepsia associated with increased motor function of the stomach. There is direct interrelation between the level of blood hormones and rate of vegetative dysfunctions and it testifies the role of the neuroendocrine system in the development of diseases of gastrointestinal system in adolescents.

[Role of somatotropin in the development of functional diseases of the digestive system in adolescents].

To determine the role of adenotropic hormones in formation of a functional pathology of the system of digestion in teenagers, somatotropin concentration in 160 patients with gastroesophageal reflux disease, functional dyspepsia and biliary dyskinesia has been studied. The tendency to the increase of the level of the hormone has been observed in patients with these diseases, especially it was obvious among 15-year old patients and teenagers with endocrine pathology. The author reveal different variations of concentration of somatotropin depending on a clinical form of the vegetative dysfunction in connection with functional diseases of the gastrointestinal system, biliary dyskinesia, vegetative nervous system, teenagers.

[Morpho-functional status of the hypophysial-thyroidal system in patients with functional disorders of the digestive tract].

The author has studied the character and frequency of changes of the hypophysial- thyroidal system in patients with gastroesophageal reflux disease, gastric dyspepsia and biliary dyskinesia in young patients aged 15-30 years. The analysis of neuroendocrine disorders, common pathogenetic aspects of the development of functional pathology of the digestive tract were carried out. It made possible to draw a conclusions concerning the right correction of these conditions.
