VARIANTS OF EEG-REACTIONS DURING HRV BIOFEEDBACK COURSE IN ADOLESCENTS WITH DIFFERENT INITIAL AUTONOMIC NERVOUS TONE
Demin D.B., Poskotinova L.V., Krivonogova E.V.
Abstract
There was surveyed a character of brain bioelectric activity change during carrying out of biofeedback sessions by heart rate variability parameters (HRV biofeedback) in adolescents aged 15-17 years with different initial autonomic nervous tone. It has been established, that adolescents with the optimal autonomic nervous tone have high reactance of both autonomic nervous system parts. At the end of HRV biofeedback course there is more significant vagal activity increase accompanied in some cases by depression of peakfrequency electroencephalogram characteristics. There was observed in adolescents with prevalence of sympathetic influences on heart rate activity against decreasing of arterial blood pressure less expressed reaction of heart rate indicators and brain functional activity optimization after the course of HRV biofeedback sessions.

Shonbin A.N., Bystrov D.O., Zavolojin A.S., Duberman B.L., Elizarov M.V., Yarkovoy M.A.
Abstract
To provide more accurate stratification models, one should systematically review the figures. In 2010, there was a re-organized multicenter study team of researchers from Papworh Hospital (Cambridge, UK). The project EuroScore II involved 154 centers from 43 countries. One of three Russian centers participating in the project was the Department of Cardiac Surgery of the City Hospital N 1 named after E. E. Volosevitch, Arkhangelsk. Purpose. Participation in a multicenter study EuroScore II for development of modern models of risk stratification of cardiac operations. Methods. There were examined 113 patients over 18 y.o. operated in May-June 2010. Complicated (nonlethal) postoperative period in patients who underwent myocardial revascularization, was observed in 19.5 % of cases, heart valves replacement / repair - in 21.1 %, the combined procedure - in 45.5 %, ascending aorta and aortic arch replacement / repair - in 0 % of cases respectively. Predicted hospital mortality among the patients who underwent myocardial revascularization was 3.7 %, heart valves replacement / repair - 5.3 %, the combined procedure - 18.2 %, ascending aorta and aortic arch repair - 100 % respectively. Conclusions. Use of scale EuroScore I may become less relevant, because there is an expansion of indications for cardiac surgery, due to improved surgical techniques, anesthesia and technical equipment provision. Scale EuroScore II may allow better assessment of cardiac surgery risk.

PROBIOTIC CORRECTION OF DISORDERS OF LIVER FUNCTIONS AND LARGE INTESTINE MICROECOLOGY IN CHRONIC VIRAL HEPATITIS
Solovieva N.V., Bazhukova T.A., Agafonov V.M.
Abstract
the aim of the work was to study interrelations between blood activity and microbiocenosis of the large intestine in chronic viral hepatitis with the use of probiotic correction. Methods. To assess the condition of the liver and large intestine microbiocenosis, a case-control study of patients with CHB, CHC was conducted. Biochemical and microbiological parameters in patients with chronic hepatitis B and CHC have been compared with healthy individuals (the control group). For a comparative analysis of these samples’ differences, the Mann-Whitney test and Fisher test were used. Results. The liver disease of viral origin was manifested in 2-3times increase in activity of serum enzymes, microbiocenosis disorders of the large intestine (lower numbers of bifidobacteria - 10 6 CFU/g and lactobacilli - 10 3 CFU/g, 30 % increase of frequency of occurrence of S. aureus and reduction to 45 % of enterococci), and voltage mismatch intersystem links (links to the weakening of (τ = 0.26)). Conclusions. Use of probiotic preparations in treatment helps to restore the liver functions by means of increased functions of the large intestine microflora that is manifested in decreased activity of enzymes, increased content of representatives of obligate microflora up to physiological values and reduced frequency of occurrence of opportunistic pathogens, recovery of the interaction of the liver and the large intestine microbiocenosis (strengthening ties to (t = 0.56)).

Eponishnikov Y.V., Kochnev A.V.
Abstract
Identifying methods of increase of efficiency and quality of training of police employees presupposes a thorough study of individual psychophysiological characteristics of students. The study was conducted for the purpose of the cadets’ central nervous system study in different periods of the 2-year training process. Visual analyzer capacity was detected. Students were selected by simple random sampling. Statistical significance was determined on the basis of the Student's (t) criterion for dependent samplings. During the monitoring period, strength of nervous processes increased by 2.7 % (р = 0.077), sustainability and attention concentration were improved by 17.0 % (р < 0.001), absolute values of visual analyzer capacity increased by 17.0 % (р < 0.001). It has been established that the two-year period of study has led to the increase of sustainability, level and distribution of attention, speed of processing of visual information and the general level of mental health.

REVISITED LOCALIZATION OF CAJAL CELLS IN SMOOTH MUSCLES OF DIFFERENT ORGANS
Zashikhin A.L., Agafonov Y.V., Lubeznova A.Y.
Abstract
Smooth muscle tissue represents a complicated and dynamical ensemble of smooth muscle cells characterized by different structural-methabolical parameters. In the composition of smooth muscle tissue a group of cell elements (cells of Cajal, ICC) is incorporated. Their structural organization and localization in smooth muscle tissue allow to consider them an important component of the system responsible for functional activity regulation. The goal of the study was to get a reliable technology for ICC isolation. The method of the alkaline cell dissociation was used. Isolated smooth cells of different organs were studied. Our findings have shown that the cells we have got by the method of cell dissosiation had clear stable morphological parameters of the interstitial cells of Cajal.
