COMPARATIVE ANALYSIS AND SYNTHESIS OF THE CARDIOVASCULAR SYSTEM INDICATORS OF REPRESENTATIVES OF ARCTIC AND ALPINE ADAPTIVE TYPES
Karpin V.A., Filatova O.E., Soltys T.V., Sokolova A.A., Bashkatova Y.V., Gudkov A.B.
Abstract
Parameters of the cardiovascular system of a group of individuals of the Arctic and alpine adaptive types from a position of the theory of chaos and self-organization have been studied. It has been established that volumes of quasiattractors of a condition vector of an organism of representatives of the alpine type right after their moving to the north were higher than the volumes of the Arctic representatives. Identification of the most significant parameters (signs) of a condition vector of a human body has been made.

ALIMENTARY STATUS OF NATIVE POPULATION OF THE NENETS AUTONOMOUS AREA
Belova N.I., Lavrinov P.A., Vorobyova N.A., Zueva T.N., Ayvazova E.A.
Abstract
Nutritive factor is one of the most important elements of human health in the Far North. Today historical lipid-protein nutrition character of the North aborigines is changed to the “European” type. This negatively influences the local population’s health. The aim of the study was to estimate the alimentary status and features of life (alcohol intake, smoking) of the Nenets autonomous area native population and its possible connection with cardiovascular disease risk. We have obtained data on the Nenets’ diet which is still based on proteins. We have estimated lack of fruits and green. Fast-food impacts life of the local population. Among the cardiovascular diseases, such risk factors as smoking (25 %) and alcohol intake (51 %) were presented. This category of population needs development of measures for prevention of cardiovascular and intestine pathology by nutrition correction and educational work on harm of alcohol and smoking.

Zaytseva N.V., Zemlyanova M.A., Tarantin A.V.
Abstract
The review considers the influence of the most common aromatic hydrocarbons (benzene, toluene, styrene, xylene) polluting the environment and being a risk factor for various health disorders, including metabolic changes in the protein profile of the human body.

CHANGES OF CATECHOLAMINS AND RHEOLOGICAL CHARACTERISTICS OF HUMAN BLOOD UNDER INFLUENCE OF HELIOGEOPHYSICAL FACTORS
Varakin Y.Y., Ionova V.G., Sazanova E.A., Sergeenko N.P.
Abstract
Correlation properties of variations of the number of hospitalized people with cerebrovascular disorders and characteristics of solar, ionosphere and geomagnetic activity have been analyzed in the article. The hypothesis was checked, that one of the internal reasons of observed biotropical effects was the level of increased catecholamins and changes of agregative properties of blood erythrocytes. The found effects are statistically significant and specify in presence of direct influences of physical processes during indignations on blood cells. Physical processes influencing cerebrovascular shifts in humans have been discussed. It has been supposed that in a storm initial stage the stochastic resonance can be one of the physical mechanisms of external influence. External electromagnetic fluctuations can synchronize or desynchronize rhythms of electromagnetic fluctuations of blood cells. Also the possibility of direct influence of geomagnetic variations during storms on the brain and the rheological properties of blood connected with influence of an electromagnetic field on dynamics of the process of aggregation - disaggregation of erythrocytes in a blood stream as in experiments in vitro and in vivo has been discussed.

GRANULOMETRIC ANALYSIS OF ATMOSPHERIC SUSPENSIONS OF BLAGOVESHCHENSK CITY
Golokhvast K.S., Chaplenko T.N., Nikiforov P.A., Chayka V.V., Pamirsky I.E., Khristoforova N.K., Gulkov A.N.
Abstract
The paper has presented the results of a study of nano- and microparticles of suspended air contained in snow in winter 2011-2012, Blagoveshchensk. The application of the laser particle analyzer for the study of qualitative and quantitative composition of atmospheric precipitation has been shown. The distribution of the particles different by sizes and genesis in the city areas with differences in anthropogenic impact has been revealed.

PREVALENCE OF ALLERGIC DISEASES IN CHILDREN IN NORTHERN AND CENTRAL REGIONS OF EUROPEAN PART OF RUSSIA
Popova I.V., Makarova V.I., Lyapunova E.V., Kopalin A.K., Chernozemov V.G.
Abstract
There has been done a comparative assessment of prevalence of the main symptoms of bronchial asthma (BA), allergic rhinitis (AR) and atopic dermatitis (AD) according to the standardized program «International Study of Asthma and Allergy in Children» (ISAAC) in children living in the northern and central regions of the European part of Russia. As pilot territories, there have been chosen the cities of Arkhangelsk and Kirov. There have been questioned 6 126 children aged 10-11 and 13-14 y.o., who were separated into two groups: the first group (n = 3 690, 1 813 boys and 1 877 girls) included the children living in Arkhangelsk. The second group (n = 2 436, 1 180 boys and 1 256 girls) included the schoolchildren from Kirov. The results of the study have detected high morbidity rates among the children’s population in Arkhangelsk and Kirov. The main symptoms of BA and AR among the children from the second group occurred more often than among the children from the first group. The symptoms of AD were observed more often in the representatives of the first group.

COMPARATIVE DYNAMICS OF BODY LENGTH AND MASS OF PRIMARY SCHOOLGIRLS IN CITY OF CHEREPOVETS
Vorobyov V.F.
Abstract
The assessment of dynamics of length and masses of a body of girls of 7-11 years trained at schools located in two districts of Cherepovets, different levels of pollution of atmospheric air was the purpose of our research. Under the patronage of the Committee for Physical Culture and Sport of the City Hall of Cherepovets within the city target program "Healthy city", assessment of the level of physical development of school pupils of the 1st - the 5th forms of Cherepovets has been carried out. Measurement of body length and mass was carried out with use of the standard anthropometrical methods by medical employees of schools. It has been established that on the termination of the primary school, the girls who were training at 6 schools of the Industrial area, have statistically authentically smaller body length and mass. Smaller sizes of a gain of dynamics of somatometric indicators have been found in them, in comparison with contemporaries who were trained at schools of the Zarechensky area.

CONTEMPORARY PERCEPTION OF ANTIOXIDANT SYSTEM OF HUMAN ORGANISM
Chanchaeva E.A., Aizman R.I., Gerasev A.D.
Abstract
Due to recently extended views on the antioxidant system of the human organism, it becomes possible to analyze scientific data on its structure, antioxidants’ role in different processes, dependence of antioxidant activity on different factors and its methods of estimation in different tissues, a farmocorrection possibility due to pathological and age changes. As a result it has been determined that the antioxidant system includes enzyme’s and inenzyme’s antioxidants acting on the intracellular and extracellular levels and participating in many physiological processes; antioxidant activity depends on alimentary and unalimentary factors, antioxidant activity is estimated with the help of alternative methods. Problems of antioxidant activity age changes and its farmocorrection possibility are still debatable.

AROMATIC AMINO ACIDS METABOLISM IN HUMANS EXPOSED TO EXPERIMENTAL SEVERE ACUTE SHORT-TERM NORMOBARIC HYPOXIA
Chernykh A.A.
Abstract
In aviation, acute hypoxia is one of the most dangerous factors affecting humans, and developing new ways of increasing human hypoxic resistance in severe acute hypoxia remains important. In this work we have studied particular features of proteinogenous aromatic amino acids metabolism in volunteers breathing hypoxic gas mixture containing 9 % of O 2. We have shown that the healthy volunteers exposed to experimental hypoxia in postprandial state significantly decreased plasma levels of free tyrosine and phenylalanine in the early recovery period. We hypothesized that these amino acids being precursors for mediators and hormones (dopamine, epinephrine, norepinephrine) can play a significant role in increasing hypoxic resistance in humans.
