SOME ASPECTS OF SYNERGISTIC ACTION OF ALUMINUM AND FLUORINE ON HUMAN BODY (LITERATURE REVIEW)
Mintel M.V., Zemlyanova M.A., Zhdanova-Zaplesvichko I.G.
Abstract
This review reflects some aspects related to synergistic effect of aluminum and fluorine on a human body. The fluorine and aluminum - highly-reactive elements are widely used in nature and belong to the 2nd and 3d class of hazard. Both elements are actively used by people in different spheres of economic activity. At present, a lot of researches have been devoted to the influence of aluminum and fluorine on a human body. However, often the studies did not take into account the synergetic effect of these elements, so the detected effects could be mistakenly assigned to one of them. Often, such a joint impact of aluminum and fluoride on the organism has a synergistic character. The antagonism between fluorine and aluminum is essential in the toxicokinetics and the substances' distribution in the organism. Whereby, the mutual influence of the elements is not definite and depends on many factors. One of the mechanisms of synergetic action of aluminum and fluorine can be caused by the formation of fluorine-aluminum compounds that function in the body in a manner similar to phosphate groups. The complexity and ambiguity of the joint effect of aluminum and fluorine on a human body, as well as the interaction of both elements, necessitate further study of this issue.

SCHOOLCHILDREN’S FUNCTIONAL STATE UNDER INTENSIVE INFORMATION LOAD AT THE INITIAL ADAPTATION PERIOD TO EDUCATIONAL ENVIRONMENT
Krivolapchuk I.A., Chernova M.B.
Abstract
Aim. The research aim is to identify peculiarities of first forms schoolchildren's functional state (FS) under intensive information load during different phases of adaptation to educational environment. Methods. Schoolchildren's FS research was carried out at comfort and at test information load during the 2nd-3rd, 6-7th and 15-16th educational weeks at school. The complex of indices suitable for schoolchildren's FS mark was used. Results. The obtained results give the evidence that at the beginning of systematic education at school the additional information loads performed with comfort and with maximal speed cause the significant (p < 0.05-0.001) rise of common CNS activation level among 6-7 aged children, tension of mechanisms of FS regulation, shift of autonomic balance to the side of ANS sympathetic part activity predominance, central regulatory influences strengthening to heart rhythm, systematic hemodynamics stimulation, as well as anxiety level rise. It has been stated that in different phases of children's adaptation to education at school the additional information loads cause, in whole, similar changes of used indices among the children. Their shifts during test tasks performance had the same focus both at 2nd-3rd, 6-7th and at 15-16th weeks of education at school, thereat, the most expressed change of FS values fell on the first weeks of systematic education (p < 0.05-0.001). Conclusions. With the development of adaptation process to educational environment among the children in the conditions of test load the tendency of less significant changes of FS indices has been observed on the background of activity effectiveness rise.

INDICATORS OF DEVELOPMENT IN THE PRESHOOL PERIODAS A WAY TO PREDICT SCHOOL ADAPTATION OF FIRST-YEAR PRIMARY SCHOOL STUDENTS
Kazakova E.V., Sokolova L.V.
Abstract
The article is devoted to the analysis of the long-term consequences of the influence of unfavorable facts and situations in the preschool period on the success of the child's adaptation to school. The aim of the work was to study the relationship between the indicators of the preschool development period and the characteristics of the cognitive, emotional, behavioral components of the first-formers school adaptation. Methods. To identify the developmental features before the school and the characteristics of school adaptation 193 first-formers in Arkhangelsk were examined. Results. It is shown that as the child grows, the interrelation between the developmental features of the child and the components of school adaptation increases: if the indicators of the infant period are associated with the emotional component and the characteristics of the early childhood period (1-3 years) are associated with the emotional and behavioral characteristics, the characteristics of the pre-school development period (3-7 years) have high correlation with the cognitive, emotional and behavioral components of school adaptation. Conclusions. The findings suggest that the developmental features of a child aged 3 to 7 years, more than other previous stages of ontogeny, affect the ability of a first-year student to adapt to systematic learning activity. The construction of regression models revealed the key interrelationships between the investigated indicators of the child's preschool development and the components of school adaptation. The authors emphasize that the analysis of the child's developmental features before school makes it possible to get an idea of presence of dysontogenesis risk factors and to determine the focus in the corrective-developing work taking into account individual characteristics.

THYROID HORMONES AND ANTIBODY LEVEL IN HEALTHY RESIDENTS OF THE ARKHANGELSK REGION
Gorenko I.N., Kipriyanova K.E., Tipisova E.V.
Abstract
The aim of the study was to compare ratios of total and free fractions of iodothyronines (T3/T4, fT3/fT4) and integral thyroid index ((fT3 + fT4)/TSH) in euthyroid subjects that had negative of antibodies values and euthyroid subjects that had positive antibodies (antibodies to thyroid peroxidase - AntiTPO and / or antibodies to thyroglobulin - AntiTG). Methods. A total of 95 apparently healthy people were enrolled in this study and classified into two groups. Group A (n = 72) had normal values of thyroid hormones and negative values of antibodies, i. e. AntiTPO < 50 IU/ml and/or AntiTG < 100 IU/ml. Group B (n = 23) had normal values of thyroid hormones and positive antibodies, i.e. AntiTPO > 50 IU/ml and/or AntiTG > 100 IU/ml. Serum thyroid hormones and antibodies concentration was measured by enzyme immunoassay. Results. Euthyroid subjects with positive thyroid antibodies have less values of (T3 + T4)/TSH (Me = 12,9 vs. 15.7, p = 0.01), T3/T4 (Me = 0.015 vs. 0.017, p = 0.02) and fT3/fT4 (Me = 0,24 vs. 0.27, p = 0.03) ratios than subjects with negative antibodies, as well as value of free triiodothyronine (Me = 3.9 vs. 4.7 pmol/l, p = 0.02). In the group of individuals with positive antibodies AntTPO significantly correlated with thyroid-stimulating hormone (r = 0.45; p = 0.02) and T3/T4 ratio (r = -0.43; p = 0.03). Conclusion. This finding may point to a decreased ability of tissues thyroxine deiodination in individuals with elevated thyroid antibodies levels.

THE INFLUENCE OF LOCAL COLD
Eskov V.V., Beloshchenko D.V., Bazhenova A.E., Zhivaeva N.V.
Abstract
The problem of studying the effects of climatic-ecological factors of territories to the formation of specific conditions of the human environment and human health in general is very relevant. The study of influence of such factors on the functional state of the body, it is expedient to study within the framework of the new theory of chaos-self-organization (there are a number of fundamental differences from the tacit stochastic approach). In this regard, we set the aim: consider and forecast in individual and groups the characteristics of the state of the neuromuscular system of a person living in the territory of the Khanty-Mansiysk Autonomous Okrug - Yugra from the standpoint of chaotic dynamics of electromyograms parameters. New methods of data visualization were used (obtaining phase portraits EMG in coordinates x(t) - muscle biopotentials, and x2 = dx/dt - the rate of their change) recorded using an electromyograph, a time scan of the signal was constructed, which was converted by sampling the signal into some numerical series and for them the parameters of quasi-tractors were calculated. Results. In the work, multiple measurements of the parameters of the bioelectrical activity of the muscle were analyzed from the position of the Eskova-Zinchenko effect, i. e. with repeated (identical) experiments before and after a local cold exposure in a group of girls. Analysis of the obtained time series showed that the signal is always unique for each recording interval for each subject. Cooling of the limb leads to an increase in the size of quasi-tractors, which is difficult to document in the framework of statistics (there is a continuous statistical change in electromyograms). Conclusions. The practical possibility of applying the method of multidimensional phase spaces (calculation of quasi-tractors parameters) for identifying real changes in the parameters of the human neuromuscular system in conditions of cold stress is proved. Calculation of the parameters of quasi-tractors is necessary as a quantitative measure of the reaction of the organism to external influences.

NEUROEPIGENETICS OF BIPOLAR DIATHESIS: FROM THE SYNDROME OF MENTAL IMMUNE PROFICIENCY TO THE SYNDROME OF MENTAL IMMUNE DEFICIENCY
Sidorov P.I.
Abstract
The aim of the article is the conceptual and methodological substantiation of epigenetic dysfunctions of mental immunity in the development of bipolar diathesis, represented by pre-nosological states and syndromes of mental immune proficiency (SMIP) and deficiency (SMID). In the onset of bipolar disorder (BD), these syndromes evolve into the manic phase (MPh) and/or depressive phase (DPh) of the disease. The allocated syndromes transgenerationally accumulate epigenetic labels of future possible BD and other mental diseases. Their pre-nosological functional diagnostics allows for screening and early prevention of mental disorders. These syndromes are the initial dysfunctional link in the development of the mental epidemiological cascade: mental epidemics - destructive mental epidemics - the pandemic of mental immune deficiency. Pandemic of mental immune deficiency is manifested by an increase in the prevalence of all mental and psychosomatic disorders, requiring a shift in the focus of preventive-corrective efforts to early pre-nosological fractals of the disease development. The clinical model of BD shows the pathoplastics and pathokinetics of mental immunity dysfunctions in the development of the disease. Mental immunity as an identity matrix predetermines the lateral mental constitution of the personality and the resources of its mental resilience. It is suggested to consider the clinic of mixed forms of BD as a manifestation of the ambidextral mental constitution. In the development of the BD, three pre-nosological fractals are distinguished: 1) predisposition - a bipolar family; 2) latent - bipolar diathesis (SMIP/SMID); 3) initial - the onset of the BD; and three nosological: 4) the full-scale clinical picture of BD (MPh and/or DPh); 5) chronization - the types and forms of the course; 6) outcome - somatopsychic and socio-moral complications.
