[VEGETATIVE REGULATORY MECHANISMS IN DIFFERENT GEOMAGNETIC CONDITIONS DEPENDING ON A DEGREE OF PHYSICAL CONDITIONING].

The aim of the study was to evaluate the vegetative regulatory action in healthy, untrained and trained individuals in different geomagnetic conditions. The study involved 94 healthy untrained young men aged 18-22 years - I group (control), and 60 trained volunteers aged 18-25 years - II group, who during the period of the study and for at least three years prior have been following active regular physical exercise regimen(weight lifting), but were not professional athletes. In order to evaluate the heart rate variability the following statistical indicators were studied: arithmetic mean, the arithmetic mean of the error variance, dispersion, the arithmetic mean deviation, coefficient of skewness, kurtosis, standard deviation of the mean.

[KINETICS OF PHOTO-INDUCED FREE RADICALS IN THE HUMAN HAIR CHESTNUT COLOR AFTER SHORT PERIODS OF RED, GREEN, BLUE AND WHITE LIGHT EXPOSURE].

The aim of the study was to investigate the kinetics of photo-induced free radicals in the human hair chestnut color with short-term exposure to visible light in different frequency ranges. Studies carried out on human volunteers aged 17-21 years (n=37). Hairs of volunteers of the study were not treated with dyes and other active cosmetic preparations.

[VISIBLE LIGHT AND HUMAN SKIN (REVIEW)].

Biological effect of a visible light depends on extend of its property to penetrate into the tissues: the greater is a wavelength the more is an effect of a radiation. An impact of a visible light on the skin is evident by wave and quantum effects. Quanta of a visible radiation carry more energy than infrared radiation, although an influence of such radiation on the skin is produced by the light spectrum on the boarder of the ultraviolet and the infrared rays and is manifested by thermal and chemical effects.

[Characteristics of heart rate variability in healthy adolescents and male adults].

The primary purpose of the present article is to investigate the comparative characteristics of heart rate variability in healthy adolescents and male adults. The study was carried out on 41 male adolescents aged 15-16 years and 73 male adults aged 18-22 years. For assessment of heart rate variability statistical data of variability and spectral analysis of heart rate were estimated.

[The prognostic significance of heart rate variability during the type 2 dm developed with the ischemic heart disease and arterial hypertension].

In recent decades the special attention is given to the Heart Rate Variability (HRV) to assess the prognosis of the patients with cardiovascular diseases. There were studied 47 male with arterial hypertension and heart failure, by which the HRV was researched. In the group of patients with type 2 diabetes mellitus (DM), ischemic heart disease (IHD), arterial hypertension (AH) and heart failure (HF), the heart rate variability (HRV) has been considerably lowered in comparison with the group of patients at which the presence of DM was absent.

[Psychopathologic peculiarities in patients with diabetes mellitus and non-proliferative retinopathy].

The aim of the present work was to study clinical course of depression in patients (pts) with diabetes mellitus (DM) and non-proliferative retinopathy (NPR). In total, 250 pts with DM were included into the study, and more separated into 2 groups (Gr): Gr.1 (n=115)--pts with DMT1 and DMT2 without NPR; mean ABP - SBP < or = 130 mmHg/DBP < or = 85 mmHg.

[Positive effects of angiotensin [corrected] receptor blockers on the course of microvascular complications of diabetes mellitus].

The aim of the research was to evaluate some clinical and hemodynamic characteristics in patients with diabetes mellitus type 1 and type 2 (DM type 1 and DM type 2), to diagnose diabetic retinopathy (DR) on early stage of its development for the correction of the disease by treating with angiotensin II type 1 receptor blocker (AT I)--Candesartan. Totally 250 patients (pts) with DM type 1 and DM type 2 were studied; they were divided into 3 groups (Gr.): Gr.

[Basic hemodynamic and vegetative regulatory indices in adolescents-healthy and sick with arterial hypertension].

Basic hemodynamic indices in aged 15-16 practically healthy adolescents do not differ essentially, but in patients with juvenile arterial hypertension is noticed their authentic rise in proper age groups. The correlation of body mass is marked with the basic hemodynamic parameters and likewise the indices of double production depend on systolic pressure and heart rate. In adolescents troubled with juvenile arterial hypertension is noticed intensification of sympathetic link of regulatory mechanisms of vegetative nervous system and unsatisfactory hypersympathetic reaction on orthostatic test which shows the total disbalance of the organism.

[Clinical characteristics of juvenile systemic hypertension in the population of Tbilisi].

The goal of the work was to study a prevalence of juvenile systemic hypertension among 15-16 years old adolescents of Tbilisi, its clinical characteristics and several indices of mental capacity. In the result of an analysis of 378 adolescents' blood pressure records only 6 (1.6%) had high normal values and 32 (8,46%) revealed juvenile systemic hypertension.

[Sensory and psychoemotional productivity in the type I diabetes mellitus].

Depressive psychosis with anxiety or without it is the most spread disorder among the patients with diabetes mellitus. According to our investigations the depression was found in 36.6% of cases of patients with the I type diabetes mellitus which affects negatively their mental working ability.

[Differential description of heart rate regulatory mechanisms of young men at sensory-motor and psychoemotional load during high frequency sound exposure].

The goal of the study was the differential description of the heart rate regulatory mechanisms of young men and productivity of task performance during sensory-motor and psychoemotional load on the background of high frequency (4000-8000 Hz) sound exposure. Analysis of statistical and spectral components of the heart rate variability was done for description of heart rate regulatory mechanisms. Sensory-motor and psychoemotional load was studied with Landolt rings.

[Regulatory mechanisms of young men heart rate during psychoemotional load accompanied by irritation with different sounds].

The goal of our research was to evaluate regulatory mechanisms of young men heart rate during psychoemotional load on the background of sound irritations of different characteristics. The study was a community trial and performed by single blind method on volunteer young men (age 18-22, n=73). As a method of description of heart rate regulation mechanisms, analysis of heart rate variability was selected.

[Changes in the interrelationships between the autonomic nervous and cardiovascular systems during different weather and heliogeophysical conditions in patients with myocardial infarct and hypertension].

The author attributes the possibility of a substantial cardiovascular damage (complications, myocardial infarctions, fatal accidents) in the population of hypertensive and myocardial infarction patients to a combination of the adverse factors of unstable weather brought in by a magnetic storm and those of emotional stress.
