In recent decades, great achievements in the field of geology, astronomy and
cosmology attracted attention of the scientific community to study of biotropic
effects of heliogeophysical factors, especially to different anomalies of natural
magnetic fields. A new branch in science - magnetic biology has appeared. Several
strategic directions in study of magnetic biological effects have been outlined so
far: importance of natural magnetic anomalies in complex biotropic impact of
various adverse ecological factors on human body; interrelation of
heliogeomagnetic activity with climatic elements of regions; study of features of
magnetic biological effects in the territory of the northern latitudes where biogenic
effects of heliogeomagnetic anomalies are most vivid. The obtained results
necessitate the need of a wider research of heliogeophysical factors’ risk for
population health in the northern urban territories.
Keywords: geliogeomagnetic activity, biotropic effects, northern latitudes

With the help of the neural network technologies, there has been developed a
council forecasting information system allowing to forecast concentration of
polluting substances in an industrial center’s air basin depending on meteorological
conditions in studied territory. The forecast’s results have been compared with the
results of the classical model - the regression analysis.

In the paper, results of a substantial study of nano- and microparticles of
atmospheric suspensions contained in snow in winter 2011-2012 in
Blagoveshchensk have been presented. Distribution of airborne particles of
different origin in 25 areas of sampling differing in anthropogenic loadings has
been determined. Large and average-sized traffic centers supply in the atmosphere
microparticles of rubber, asphalt andvarious metals and their oxides (Fe, Ni, Co,
Cu, Fe, Bi, W). Railway junctions are a source of microparticles of Fe and soot
which get to the atmosphere because of friction of metal surfaces and diesel
locomotive engines operation. Parks and suburban districts are a source of microand macroparticles of natural minerals and rocks and of vegetable detritus. It has
been shown that composition of atmospheric suspensions of Blagoveshchensk
completely corresponded to ecogeographical prerequisites - the bank of two large
rivers, small impact of enterprises and motor transport, a large railway junction.

According to the results of the cross-sectional study of rural indigenous population
of the Republic of Sakha (Yakutia), there has been studied the level of cholesterol
and frequency of atherogenic changes of the lipid profile of the blood plasma. It
has been found that in 35 % of the surveyed indigenous people, the level of
cholesterol was 5.2 mmol/l or more, and in 10.8 % - 6.2 mmol/l or more. Among
the persons with high cholesterol, atherogenic changes of the ratio of total
cholesterol / HDL-C, LDL-C / HDL-C were observed in 19 % of the men and 8 %
of the women (р = 0.014); logarithm (TRG / HDL-C ) - in 11 % of the men and
women (p = 0.906). Thus, the high levels of the total cholesterol (5.2 mmol /l or
more) in 80 % of the men and in 89% of the women was not accompanied by
atherogenic changes in the lipid profile. This allows to consider the status of
hypercholesterolemia in this population group in most of the cases as a
manifestation of adaptive changes in lipid metabolism. The identified changes in
atherogenic lipid profile were associated with presence of metabolic risk factors,
what proves the need for determination of cholesterol in lipoprotein composition
and a ratio of lipid fractions for choice of a right tactics for correction of the lipid
risk factors.

CARDIORESPIRATORY SYSTEM’S INDICES IN YOUNG MEN WITH
DIFFERENT BLOOD CIRCULATION TYPES

It has been established that under stress-factor influence, responses of the
cardiorespiratory system in the young men with the hyperkinetic type of blood
circulation were connected with stimulation of chronotropic spectrum of central
hemodynamics. In the young men with the eukinetic type of blood circulation,
responses were connected with stimulation of inotropic spectrum of central
hemodynamics. All the responses depended on the state of bronchial conductivity
of the respiratory system. In the persons with the hypokinetic type of blood
circulation, the external breath system was intensively included in compensatory
activity. Influence of hemodynamical factors was insignificant in the persons with
this type of blood circulation. A large degree of freedom in choice of different
variants of responses to influences of stress-factors improves compensatory
possibilities of the cardiorespiratory system in the young men with the hypokinetic
type of blood circulation.
Keywords: cardiorespiratory system, young men, type of blood circulation

With the use of the method of inverse voltammetry, we have analyzed some
specific features of trace element status of children aged 1-3 years in TroitskoPechorsk of the Komi Republic taking into account the content of these elements in
the environment (drinking water, snow cover). It has been found that the
permissible content of zinc was observed in biosubstrates of 40 % of the examined
children, copper - in 15 %, lead - in 20 %, and cadmium - in 65 %. The detected
changes in the trace elements exchange in the examined children serve as a basis
for formation of different diseases.

Under modern conditions, the schoolchildren’s sensor systems experience more
strains because of increasing amount of information, training activities
intensification, severization of requirements to accuracy and speed of cognitive
processes what exerts negative influence on the visual analyzer state first of all.
The cross-sectional research was conducted with the purpose of studying visual
perception components and sensory-motor reactions parameters of 7-8-year-old
children with strabismus and amblyopia. The results of the visual perception
components research with the use of the method of M. M. Bezrukikh, L. V.
Morozova and sensory-motor reactions estimation with the help of the computer
complex “Psychomat” of 118 children aged 7-8 years with normal and impaired
vision have been presented. Decreased noise-immunity and visual perception
constancy, visual analysis-synthesis realization lag have been revealed among the
schoolchildren with strabismus and amblyopia. It has been found that sensorymotor reactions time in the children with strabismus and amblyopia was
statistically longer than in children of the same age without impaired vision.
Keywords: northern children, visual perception components, sensory-motor
response, reaction time, strabismus, amblyopia

In the article on the basis of the synergetic bio-psycho-socio-spiritual methodology
of mental ecology and mental medicine, there has been considered the design of
virtual images and narrative meanings through the example of the modern English
serial “Sherlock”. There have been described the phenomenology and mechanisms
of realization of pathoplastic factors of mental ecology of the Anglo-Saxon world
personified in the figure of the central character and accumulating urgent
characteristics of social mind and mental health, social and personality identity.
There has been grounded the necessity of adaptive development of social mind and
introduction of mental health system monitoring allowing to assess effectiveness of
mechanisms of morality interiorization and its translation to the level of individual
morals.

Individual psychomotor reactions in servicemen of special forces in the dynamics
of performance of their service and combat missions have been studied. The data
on personality psychological properties and functional processes in the nervous
system of the servicemen in reference to different service length has been
presented. The study has found that the reliability coefficient in the samples tended
to decrease, but at all the studied stages, it was statistically significantly higher in
the more experienced servicemen. There have been analyzed the most important
parameters of responses to visual stimuli.
Keywords: psychomotor reactions, servicemen, professional activity
