[Personalization of Nordic walking programs in a sanatorium-type medical center]. / Personifikatsiya programm skandinavskoi khod'by v usloviyakh meditsinskogo tsentra sanatornogo tipa.

Nordic walking is a wellness technology available to people of all ages with varying fitness levels and health conditions. The greatest health strengthening effect when using it is achieved in those cases when the program is personified depending on a specific disease taking into account the current functional state of the body and system-forming parameters of activity including the initial vegetative tone. OBJECTIVE: To assess the effectiveness of Nordic walking in adolescent 15-17 years old depending on type of initial vegetative tone and the time of the lessons. MATERIAL AND METHODS: It was examined 60 adolescents aged 15-17 years of the II health group including 30 persons with vagotonic and 30 persons with sympathicotonic type of initial vegetative tone. In each groups the subgroups were identified who were engaged in Nordic walking from 8:00 to 9:00 (morning subgroups, 15 teenagers) and from 18:00 to 19:00 (evening subgroups, 15 teenagers). The course included 21 sessions of 45 minutes daily. Heart rate variability, the level of self-esteem according to D. Keirsey, well-being, activity and mood according to the SAN method, subjective load tolerance according to the Borg scale and general physical endurance according to the results of a test with a 6-minute run were assessed. RESULTS: A significant positive effect was observed with the differentiated use of Nordic walking taking into account the type of the initial vegetative tone and the daily rhythm of physical activity. In adolescent vagotonics training in the evening according to the analysis of heart rate variability, the functional reserve and activity of regulatory systems increased with a tendency to normalize the sympathetic-parasympathetic balance, the indicators of the psychological sphere improved, physical endurance increased, as well as the motivation for training and their subjective tolerance. In sympathicotonic adolescents, a similar positive effect of Nordic walking took place when exercising in the morning. A different distribution of training time (morning hours for vagotonics and evening hours for sympathicotonics) was accompanied by tension in the work of the autonomic nervous system apparatus caused disharmony in the emotional state, did not lead to an increase in physical endurance and worsened subjective load tolerance. CONCLUSION: When planning a course of Nordic walking in adolescents it is necessary to take into account the type of initial vegetative tone and choose the right time for classes: with vagotonia they should be carried out in the evening, with sympathicotonia - in the morning.

[The clinical significance of evaluation of the inflammatory infiltrate in chronic gastroduodenitis in children].

OBJECTIVE: To establish the diagnostic value of the determination of leukocyte composition of inflammatory infiltrate in chronic gastroduodenite in childhood. PATIENTS AND METHODS: We examined 103 patients aged 8-17 with chronic gastroduodenitis associated with Helicobacter pylori. To detect Hp and Epstein-Barr viral infections we used esophagogastroduodenoscopy, quick urease test, bacterioscopy of gastrobiopsies. We performed the analysis of the cellular composition of the inflammatory infiltrate. RESULTS: It was found that the number of lymphocytes and neutrophils located in the lamina and intraepithelial increases, which is associated with the degree of inflammation. Increased to the maximum was the number of intraepithelial lymphocytes, both in the body, and in the antrum. Intensity of leukocyte infiltration is directly correlated with the increased prevalence of inflammation. Persistence of Epstein-Barr virus (35.9% of patients) is followed by more severe intraepithelial lymphocytic infiltration in the stomach. In 4-6 months after treatment 18 patients with severe gastritis were repeatedly studied for the inflammatory infiltrate. A significant decrease in the number of intraepithelial neutrophils was found. CONCLUSION: Cellular composition of the infiltrate is an objective characteristic of chronic inflammation in the gastric mucosa. Persistence of Epstein-Barr virus is accompanied by an increase in the amount of intraepithelial lymphocytes and neutrophils.

[Pathology of microhemocirculatory vessels in congenital heart defects with left-to-right shunt]. / Patologiia sosudov mikrogemotsirkuliatsii pri vrozhdennykh porokakh serdtsa so sbrosom krovi sleva napravo.

Pathology of microcirculatory vessels of greater omentum and bulbar conjunctiva in children with congenital heart disease presenting with a left-to-right shunt was studied by biomicroscopic and morphologic methods. It has been shown that in this disorder of central hemodynamics the progressive reduction of true capillaries arises both in bulbar conjunctiva, and especially in the omentum. The authors believe that such deficit of tissue blood supply leads to reduction of density in terminal vascular networks and to the simplification of the construction of microcirculatory, in which the number of main microvessels (capillaries) increases, thus combining directly arterioles and venules, resulting in blood flow centralization and decrease of the efficiency of microcirculation.
