MECHANISMS OF RESPIRATORY FUNCTION CHANGES AS RESULT OF AUTUMN AND WINTER AIR TEMPERATURE FALL
Shishkin G.S., Ustyuzhaninova N.V.
Abstract
In the study, there have been examined the mechanisms of external respiration changes in 20 healthy young men living in Western Siberia during an autumn and winter air temperature fall. Spirography and measuring of the lung volumes were performed in a warm room and after a 30 minutes stay in the open air in natural conditions, when the air temperature was from 0 ° to -30 °C at different times. It has been discovered that under the inspiratory air temperature fall, the tidal volumes also decreased. That raised dilution of the inspiratory air in warm alveolar gas and stabilized temperature in the lungs respiratory regions. At the same time, a decrease in the tidal volume led to a decrease in minute ventilation and alveolar oxygen partial pressure in the alveoli. The latter was compensated by an increase in the lung respiratory regions airiness, which increased ventilation efficiency and the lung diffusion capacity. Therefore, the homeostatic respiratory function and thermoregulation were coordinated.

INFLUENCE OF FOOD CHEMICAL POLLUTION ON HEALTH OF POPULATION OF YAMAL-NENETS AUTONOMOUS AREA
Turchaninov D.V., Brusentsova A.V., Kharkov V.V., Kharkova E.A.
Abstract
Population health is determined by the compound action of a diversity of medico-social factors. With the application of a risk assessment methodology in this work, influence of food on health of the Yamal-Nenets Autonomous Area’s (YNAA) population was evaluated in 2006-2008 taking into account negative effects of chemical substances contained in the food. The risk level concerning non-carcinogenic effects caused by the exposure to such substances was unacceptably high. The aggregate hazard indices (for critical target organs) calculated on the basis of the median and the 90th percentile were larger than 1. The YNAA population has a high risk of exposure to such pathological non-carcinogenic effects in consumption of vegetables and fruits, berries, juices, bread and bakery foods, sugar and confectionery, meat and meat products. “Target organs (systems)” were blood, the gastrointestinal tract, the immune, hormone- and cardiovascular systems. Basic substances which influenced negatively human health were arsenic, T2-toxin and nitrates. The risk level of cancer development was also characterized as unacceptable for the population. Most of the carcinogens entered the organism with such products as vegetables, fruits, berries and juices, fish and sea foods. The greatest contribution to the aggregate carcinogenic risk was made by arsenic, which was mainly contained in the group “fish and sea foods”.

LEVEL OF REGIONAL SOCIAL AND ECONOMIC DEVELOPMENT AND LABOR SAFETY INDICATORS IN MURMANSK REGION
Karnachev I.P., Nikanov A.N., Koklyanov E.B.
Abstract
Calculation of incompletely produced gross regional product in case of a fatal occupational accident in the Northwestern Federal District (NFD) has been done. The territorial indicators were high in the Vologda region and the Komi Republic. Eight NFD regions of ten including the Murmansk region are in the group of high and better-than-average levels of social and economic conditions’s opportuneness for occupational safety.

FEATURES OF INTRODUCTION OF MEDICAL CARE STANDARDS IN TREATMENT OF ADOLESCENTS WITH GASTRIC ULCER IN DAY CARE UNIT
Belousova I.G., Menshikova L.I., Vyazmin A.M., Makarova V.I.
Abstract
Analysis of the standards implementation for teenagers with Gastric ulcer (ICD-10 Version: 2010) treated in a day care unit has revealed that frequency of diagnostic tests provided was out of standards in 88,8 % of cases. Both excess and lack or absence of diagnostic procedures were reported. Abdominal Ultrasound, Fecal Occult Blood Test, Platelet Count, Bilirubin Blood Test, Liver Transaminases, Pancreatic Enzymes were among tests that exceeded the standards of care. pH measurement, Gastric Intubation, X-ray, Immunology laboratory tests, Blood Group Test ABO and Rhesus (D) test were lacked or absent. The standard approved makes no provision for medication dosage calculation based on body weight in kg. This has to be considered when teenagers and children are treated. This standard can be applied for teenagers with Gastric ulcer treated in a day care unit. It is essential to make separate patient models for children and adults to improve quality of medical care and to exclude unregulated drug administration.

ESTIMATION OF FUNCTIONAL CONDITION OF HEART RATE VEGETATIVE REGULATION IN PRIMARY SCHOOLCHILDREN
Sinitskaja E.Y., Volokitina T.V.
Abstract
Spectral parameters of the heart rate variability in 218 children (111 boys and 107 girls) have been estimated with use of various test loads. There have been detected functional features of regulatory structures’ (controlling the heart rate) reactions to intellectual and physical loads depending on age and levels of intellectual and physical working capacity. The data on heterochronous nature of maturation of structures responsible for the heart rate regulation during mental and physical activity in primary school children have been received.

EFFECT OF MOTHER’S PATHOLOGIC GESTATION COURSE ON PHYSICAL DEVELOPMENT OF CHILDREN AT BIRTH, AT AGE 1 YEAR AND 7-8 YEARS
Tulyakova O.V.
Abstract
The study retrospectively investigated the percolation characteristics of the perinatal period and during the first year of study at school - especially physical development of 919 first-formers from 17 schools in the city of Kirov. It has been established that the perinatal period pathology exerted different influence on the components of physical development of the children. Late preeclampsia in the history had no effect on anthropometric indices at birth and at the age 1 year, but reduced them at the age 7-8 years. Anemia and placental insufficiency in anamnesis influenced the anthropometric parameters at birth, but was not manifested at the age 1 year and 7-8 years. The value of the circumference of the chest and the Rohrer index, the value of vital capacity, speed of growth processes and harmonious physical development were most vulnerable to the pathologies of the perinatal period and continued up to the age 7-8 years. Among the studied pathologies, late gestosis (reduced anthropometric parameters and affects on the cardiovascular system) and fetoplacental insufficiency (reduced rate of growth processes and harmonious physical development) exerted the most negative influence at the age 7-8 years.

ANALYSIS OF WORLD TENDENCIES IN DEVELOPMENT OF SEXUAL CULTURE OF ХХ - ХХ! CENTURIES
Svetlichnaja T.G., Mosjagin I.G., Gubernitskaja S.V.
Abstract
The paper presents an analysis of major trends in sexual culture development in the contemporary society. Based on studies of domestic and foreign experts, there has been given a characteristic of sexual behavior of people around the world. The latter is characterized by global changes in sexual relations between people: earlier age of sexual debut, the changing nature of family relations, the liberalization of sexual morality and the erosion of gender stereotypes, etc. Negative trends in the observed sexual culture development are observed in Russia. They are primarily manifested in the wide spread of sexually risky behavior among teenagers and young people. This leads to an increase in the number of unwanted pregnancies, abortions, STI / HIV, and consequently to a deterioration in sexual and reproductive health, what specifies a need to develop effective programs of sexual education of the population.

SOME PECULIARITES OF PREVALENCE OF ONCOLOGIC MORBIDITY OF RUSSIAN FAR EAST POPULATION
Bolotin E.I., Lubova V.A.
Abstract
A geographical analysis of oncologic morbidity in the Russian Far East has detected only small territorial differences of levels of manifestation both of general oncologic morbidity and its separate localizations. It is supposed that genetic predisposition of the Russian Far East population to oncologic morbidity is the reason of the current onco-epidemiological situation.
