Vegetative Status

In recent years, negative demographic phenomena are growing in Lviv region as well as in Ukraine on the whole. They are manifested in falling birth rates, rising mortality, rising morbidity which are inextricably linked with ecological imbalance and environmental degradation in general. The aim of our research was to identify the features of the degree of stress of the adaptation mechanisms, vegetative status and functional health (of population) of “radiation-clean” Lviv region and compare the results with the results of FEE of “radiation-contaminated” Vinnytsia and Chernihiv regions. We examined 1592 children of different ages and sexes living in Lviv region with the help of functional-vegetative diagnostics (FVD) of vegetative health by the method of V.G. Makats, which allows us to identify indicators of variance of vegetative levels that act as integral bioindicators of internal homeostasis. The bioelectrical activity of 12 symmetrical pairs of functionally active zones of the skin (24 PHASES), 12 on arms and 12 on legs, which reflect the functional activity of the sympathetic and parasympathetic nervous systems was studied. Atmospheric air pollution, drinking water quality, waste accumulation are the main factors that harm the health of the population. Emissions of pollutants into the atmosphere from stationary sources of pollution in Lviv region in 2019 were 16.7% less than in 2018. The overall dynamics of pollutant emissions in 2000-2019 was characterized by a downward trend, from 108.6 thousand tons in 2000 to 88.9 thousand tons in 2019. In 2019, 1.0% more waste was generated in Lviv region than in 2018. In 2019, 858 kg of waste was generated per capita in Lviv region, that is 99 tons per 1 km2. The Lviv region is not included in the radiation control zone of Ukraine and is considered to be «conditionally clean». While studying the variance of vegetative levels and, accordingly, the functional health of children in Lviv region in 2001-2006, we found that in female and male groups vegetative dynamics had a «sympathetic orientation» (critical functional stress of adaptation), so the percentage of surveyed children included in the zone of increase of sympathetic activity fluctuated from 36% in 2006 to 64% in 2004 in the female group under supervision and from 36,5% in 2003 to 55,7% in 2006 in male that is much higher than 15%. of the norms. The critical advantage of «sympathetic dispersion» is not ideal for functional health, but in this situation it indicates the absence of a «radiation component» of the integrated environmental pressure. Functional and ecological examination of Lviv region in 2001-2006 revealed its relation to the zone of «functional protection tension». We noted an opposite situation during long-term observations of the dynamics of functional health of children in Vinnytsia and Chernihiv regions which belong to the 4th zone of state radiation control. In addition, the children living in these regions were characterized by the development of persistent parasympathicotonia (vagotonia). While analyzing the state of functional health of children due to the vegetative coefficient (kV), which characterizes the adaptive potential of the population, it was found that at a rate of kV 0.95-1.05, which corresponds to the vegetative balance, in all gender groups and in all years of observation it is at much higher levels. Its average value ranged from 1.15 in 2002 to 1.30 in 2004 and 1.19 was the overall average for all years of observation. Speaking about children living in Lviv region, there are changes that reflect the imbalance of the autonomic nervous system towards the predominance of sympathetic regulation, accompanied by increased energy needs.Prolonged predominance of sympathetic regulation leads to depletion of energy reserves and, as a consequence, can provoke the emergence and development of diseases of various etiologies.

The concept of functional and ecological expertise (FEE) of radiation control regions fundamentally complements the accepted forms of dosimetric and thyroid dosimetric control. The purpose of our work was to carry out the verification of radiation dependence of functional health and dosimetric certification of settlements in Haisyn district of Vinnytsia region with the help of FEE. 186 children (91 boys, 95 girls) of different age groups living in the villages of Karbivka, Kunka and Stepashky of Haisyn district during 1993-1996 were examined with the help of FVD method by V.G. Makat.s The functional health of сhild population, which is becoming a "bioindicator" of individual health and characterizing the environmental dynamics of the compact living area, is in the focal point of FEE. The ecological criterion of FEE of a particular region of the population is systemically dependent comparison of inhibition of functional activity of the organism (parasympathetic activity (PA), vegetative equilibrium (VE) and sympathetic activity (SA). An integral characteristic of the ecological state is formed on this basis and the levels (zones) of its ecological pressure are determined. The surveyed populated areas of Karbivka village, Kunka village and the village of Stepashky in Haisyn district of Vinnytsia region belong to the IV radiation control zone. Our observations have shown that functional and vegetative health of children is ecologically dependent, and its indicators are the most sensitive bioindicators of radiation (environmental) pollution. Functional vegetative health of children in the surveyed populated areas of Haisyn district coincides with the official dosimetric certification of these areas. Monitoring of vegetative health of children should become the basis of modern functional medical examination of paediatric population and supplement state dosimetric and thyroid dosimetric certification of the populated areas.

The aim of the present study was to systematically investigate the effects of chronic exposure to extremely low-frequency electromagnetic field (ELF-EMF) on electrophysiological, histological and biochemical properties of the diaphragm muscle in rats. Twenty-nine newly weaned (24 days old, 23–80 g) female ( n = 15) and male ( n = 14) Wistar Albino rats were used in this study. The animals were randomly divided into two groups: the control group and the electromagnetic field (EMF) group. The control group was also randomly divided into two groups: the control female group and the control male group. The EMF exposure group was also randomly divided into two groups: the ELF-EMF female group and the ELF-EMF male group. The rats in the ELF-EMF groups were exposed for 4 h daily for up to 7 months to 50 Hz frequency, 1.5 mT magnetic flux density. Under these experimental conditions, electrophysiological parameters (muscle bioelectrical activity parameters: intracellular action potential and resting membrane potential and muscle mechanical activity parameter: force–frequency relationship), biochemical parameters (Na+, K+, Cl− and Ca+2 levels in the blood serum of rats; Na+-K+ ATPase enzyme-specific activities in muscle tissue; and free radical metabolism in both muscle tissue and serum) and transmission electron microscopic morphometric parameters of the diaphragm muscle were determined. We found that chronic exposure to ELF-EMF had no significant effect on the histological structure and mechanical activity of the muscle and on the majority of muscle bioelectrical activity parameters, with the exception of some parameters of muscle bioelectrical activity. However, the changes in some bioelectrical activity parameters were relatively small and unlikely to be clinically relevant.

Vegetative System

In the process of ontogenesis, individual organs and systems mature gradually completing their development in different periods of life. This heterochrony of maturation determines the features of organism-functioning in children of different ages. However, the data in scientific literature do not reveal the features of the vegetative status of preschool children. Therefore, the goal of our work was to determine the level of vegetative homeostasis, which indicates the ratio of sympathetic (YANG) and parasympathetic (YIN) functional activity of the autonomic nervous system in preschool children. The methodology of functional-vegetative diagnostics (FVD) elaborated by Professor V. G. Makats (2016) allowed identifying acupunctural channels and discovered a previously unknown human functional-vegetative system. The diagnostic complex “BIOTEST-12M” (Diagnostic complexes VITA-01-M and computerized system VITA-01-Biotest) serves as the technical tool of the FVD. The specific dynamics of increasing systemic-functional stabilization indicates the formation of age-related mechanisms of functional-vegetative homeostasis and the peculiarities of physiological development of preschool children. We found 28.5% of the surveyed preschool children in the zone of vegetative equilibrium, and 50% have parasympathicotonia. The sympathetic orientation of the levels of vegetative equilibrium by the years of life of preschool children in the female group (FG) is identical and indicates the multi-directional activity of individual systemic complexes.

Electric Traction

At present, the control system of electric traction motors is widely used in four-regulators collected on thyristors in a bridge rectifier circuit. The feature switching processes in them are needed to introduce an artificial delay of the thyristors opening angle, which reduces the average value of the power factor up to 0.8. The article assesses the effectiveness of the combination of the rectified voltage from the point of view of increasing the energy performance of the band rectifiers for controlling the traction motor freight locomotives operating on alternating current. With this regulation the greatest effect is achieved in the first control zone, under normal conditions when the power factor is particularly low (0.2 ... 0.6). The expected improvement of the average power factor of the first zone will be about 22%, and taking into account the duration of the performance in all working areas, it should be about 5-10%

Background. One of the defining typical clinical and pathogenetic syndromes of the formation and severity of chronic pancreatitis (CP) are the syndromes of endogenous intoxication (SEI) and autonomic (vegetative) dysfunction (VD). We did not find any studies of hematological indices of inflammation and intoxication, and especially in comparison with the parameters of vegetative status in CP, which motivated us to conduct this research work. The purpose of the study was to establish the relationship between hematological indices of inflammation and intoxication and the parameters of the autonomic status of patients with chronic pancreatitis. Materials and methods. We examined 69 patients diagnosed with CP who were treated as out-patient. The following hematological indices were determined: leukocyte intoxication index (LII), adaptation index (IA) with subsequent determination of the type of nonspecific adaptive response, lymphocyte-granulocyte index (ILG). The correlations of LII with the parameters of psycho-emotional state (neuroticism, reactive (RA) and personal (PA) anxiety according to the Eisenk, Spielberger-Khanin questionnaires), VD according to the Wayne questionnaire, and the duration of the disease were studied. Results. 63% of patients with chronic pancreatitis were diagnosed with endogenous intoxication of mild and moderate severity according to the Kalf-Khalif index, which makes it necessary to use drugs aimed at its correction. Significant correlations were established between LII and personal anxiety (direct weak r = 0.23, p <0.05), neuroticism (direct moderate force r = 0.41, p <0.05), autonomic dysfunction (direct weak r = 0,1, p <0,05), duration of the disease (direct weak r = 0,15, p <0,05), structural condition of the pancreas by ultrasound manifestations in points (direct weak r = 0.29, p <0.05), the level of α-amylase of the pancreas (direct medium strength r = 0.30, p <0.05). The obtained results proved the presence of significant interactions between the parameters of inflammation and endotoxicosis with indicators of autonomic status and the state of the pancreas. This makes it necessary to prescribe anti-inflammatory and vegetotropic drugs to patients with CP to enhance protocol treatment. Conclusions. Among patients with CP, favorable adaptive reactions were observed in only 36% of subjects, adverse - in 25%, intermediate - in 39%, and the average value of the adaptation index was - 0.48 ± 0.18, which corresponds to the upper limit of the orientation reaction. This motivates additional prescription of vegetotropic and adaptogenic drugs to such patients with CP. Only in 10% of patients with chronic pancreatitis the general immune response has no deviations from the adequate immune response, in 48% of subjects there is an inability of the immune system to complete inflammation, in 42% - the predominance of autoimmune intoxication, which requires enhanced anti-inflammatory therapy.
