EUROPEAN AND RUSSIAN METHODS FOR EXPOSURE ASSESSMENT APPLIED ON WHOLE BODY VIBRATION VALUES IN SHORT HAUL DUMP TRUCKS
Abstract
Operating Surface Haul Trucks (SHT) exposes mineworkers to whole body vibration (WBV), but risk assessment methods are not uniform in the Barents Region. We intended to measure WBV exposure from SHT, and discuss and compare risk assessment outcome by European and Russian methods. 17 WBV measurements were performed at the operator seat interface on 14 SHTs in an open cast mine in Northwest Russia. Measurement periods ranged from 13 to 58 minutes in real work cycles during 8 hours of driving. It was found that mean WBV exposure (A(8) rms) for the 14 SHT’s was (1.0 ± 0.23) m/s 2, mean crest factor - (12.78 ± 5.26) and mean vibration dose value - (10.35 ± 2.61) m/s 1· 75. The study shows that WBV levels defining the lower limit of hazard class 3.2 (Russia) is close to the limit value 1.15 m/s 2 (European countries).

THE CORRELATION OF HEART RATE VARIABILITY DYNAMICS AND ELECTROCARDIOGRAM DISPERSION MAPPING IN HUMANS BY LONG-TERM MONITORING IN RESTING STATE
Abstract
The monitoring of performance of dispersive electrocardiogram mapping and heart rate variability in 30 healthy volunteers aged from 18 to 59 years in a state of rest was done. It was found that micro-amplitude variations of elec trocardiogram have periodic characteristics, and these fluctuations are largely determined by changes in the balance of the autonomic nervous system. Increased electrical and ion-metabolic instability of right atrium is associated with increased heart rate variability and its vagal component, and the level of micro-amplitude fluctuations variation of velocity characteristics of the initial ventricular depolarization front -with the weakening of parasympathetic activity.

CONDITION OF NONSPECIFIC ADAPTABLE REACTIONS OF THE ORGANISM AND HEALTH LEVELS AT VARIOUS MODES OF EXTREME CRYOGENIC TRAININGS
Abstract
Influence of various modes of repeated extreme general air cryogenic trainings at t = —110±5 °С on the levels of health determined by types of nonspecific adaptable reactions and a condition of reactance, is studied. The parallel group analysis with the fixed dose (only 10 sessions lasting 2,5-3 minutes) and a choice of investigated out of almost healthy persons and patients with initial stages of diseases in remission stage on the basis of requirements to a method of open stratification randomization was carried out. The received results show possibility of positive modulation of types of the adaptive reactions, being nonspecific basis of higher levels of health, practically at all three modes of cryogenic influences. Gender features of influence of extreme cryogenic trainings on the states of health (health, intermediate state, illness) are revealed determined by types of adaptive reactions of an organism and corresponding levels of reactance that it is necessary to consider when choosing a procedure mode.

FEATURES OF THE PSYCHOMOTOR STATUS OF PERSONS IN GROUPS WITH VARIOUS LEVEL OF SOCIAL ADAPTATION
Abstract
In the present article application of a psychomotor identification method is justified - as the most sensitive to the slightest dynamic changes in psychofunctional condition of a person and as independent taxonomic unit of human personality in its integrative expression. On a comparative example of 4 groups of examinees of the various socially-directed importance, connection of their psychomotor status with their social adaptedness in the environment (success or not success) is detected. It is found out that athletes in playing sports have advantage against representatives of other groups, and even before representatives of combat sports in aspect of social adaptation - presence of communicative-reflective aspect influencing formation of such mechanisms as "identification", "empathy", ''prediction'', «mutual aid and interchangeability». And it leads to early education of collective solidarity not only on a game field, but also in any real life situation. The statistical analysis has allowed to allocate "border zones" of a social optimum which serve as a reference point for purposeful psychocorrectional work with "a weak link" in aspect of self-control and selfchecking of the individual and the person.

IMPROVING THE MEDICAL ACTIVITY OF PARENTS OF CHILDREN WITH SERIOUS DISEASES
Abstract
This article presents the results of a qualitative study using focus-group discussion to collect data and content analysis of the information of the answers of informants as an analytical tool to identify the main causes of poor health activity of parents of children with serious diseases and to develop the main directions of its improvement. 18 women aged 30-55 years, parents and close relatives of children with serious diseases, medical and social workers took place in discussion. Focus group discussion revealed a social and professional policies of all representatives, allowed to come to a consensus about a common reason for the low medical activity of parents of children with serious diseases and to suggest ways to improve it.

EFFECTIVENESS OF EDUCATIONAL PROGRAM “THE SCHOOL OF WEIGHT CORRECTION” IN WOMEN, ARKHANGELSK
Abstract
The aim of the study was to assess the effect of the educational program “The School of Weight Correction”. Methods. The panel study has been done and included women who participated in the program “The School of Weight Correction” from the 1 st of January till the 31 st of July, 2010 with subsequent observation during six months. We analyzed anthropometric and laboratory data before and after six months. Results. After 6 months there were estimated the reduction of body mass (-11.32 kg , 95 % CI: -9.24; -13.4), body mass index (-2.74 kg/m 2; 95 % CI: -0.69; -6.18), waist (-9.76 cm; 95 % CI: -7.13; -12.39) and hip (-12.66 cm; 95 % CI: -6.28; -19.04) circumferences, mass (-5.86 kg; 95 % CI: -0.11; -11.84) and volume (-4.69 %; 95 % CI: -3.3; -6.08) of fat tissue, systolic (-12.97 mm Hg; 95 % CI: -4.18; -21.76) and diastolic (-9.55 mm Hg; 95 % CI: -5.68; -13.41) blood pressure, and total cholesterol (-1.1 mmol/l; 95 % CI: -0.63; -1.57). Greater basal waist circumference, longer disease duration and greater basal level of total cholesterol were significantly associated with the better waist circumference reduction. Initial body mass (OR = 1.16; 95 % CI: 1.02; 1.33), smoking habits (OR for ex-smokers = 0.17; 95 % CI: 0.04; 0.8); OR for current smokers = 0.05; 95 % CI: 0.00; 0.7) significantly influenced refusals of follow-ups. Conclusions. ”The School of Weight Correction” was effective in reduction of body mass, waist and hip circumference, blood pressure and level of total cholesterol after 6 months.

GENETIC POLYMORPHYSM IN THE GENE OF METHYLTETRAHYDROFOLATREDUCTAZA AND ITS IMPACT ON PLASMA HOMOCYSTEINE LEVEL AND ON LONG-TERM EFFECTS OF ACUTE MYOCARDIAL INFARCTION
Abstract
Hipergomocystenemia (HHC) is a significant risk factor for cardiovascular deseases. According to research in HHC incidence of acute myocardial infarction (AMI) increases by 3-4 times. There are hereditary and acquired causes of HHC. One of the reasons is the presence of inherited genetic polymorphisms in the MTHFR gene. According to research conducted by us, the level of homocysteine (HC) plasma at the time of admission was higher than the reference values in 75 % of cases (95 % CI: 60-86). On the 14th day of flow above the AMI level of HC reference values was observed in 73 % (95 % CI: 57-84) cases. The level of HC in patients with homozygous MTHFR gene polymorphism was significantly higher than in patients with heterozygous polymorphism, or without it on the first day of flow of AMI (p = 0.028), and on the 14th day course of acute myocardial infarction (p = 0.001.) In assessment of the long-term outcome after coronary flow AMI endpoints (development of re-infarction, unstable angina, stroke, repeat revascularization, death from CHD), there has been established a clear correlation between the presence of genetic polymorphisms in the MTHFR gene and the development of re-infarction (p = 0.04), the need to repeat revascularization (p = 0.003), the development of unstable angina (p = 0.001). In patients with homozygous polymorphism in the gene encoding MTHFR, re-infarction occurred more frequently (p = 0.021). These data suggest HHC, as one of the most important risk factors for AMI, as well as a higher level of HHC and more severe course of acute myocardial infarction in patients with the presence of polymorphisms in the MTHFR gene.

STUDYING OF AEROGENIC LOAD EFFECT ON BUCCAL EPITHELIAL CELLS IN PATIENTS WITH DIABETES
Abstract
The aim was to study diabetes 2 prevalence and atmospheric pollution effects among patients under different anthropogenic loads, and to study buccal epithelium electrokinetic activity. Methods. Diabetes 2 morbidity was analyzed according to Form N 12. Aerogenic load effect has been studied with use of the correlation analysis method. Epithelium electrokinetic activity (%) has been examined in 22 patients with diabetes 2 and 23 healthy persons. Results. Coefficient correlation between diabetes 2 morbidity and technogenic atmospheric pollution by copper oxide was 0.4 in relatively clean and 0.8 in industrial districts. Epithelium electrokinetic activity (%) in patients with diabetes 2 was lower than in healthy persons (17.5 ± 2.0 and 36.7 ± 2.5, respectively). Conclusion. Interrelation between diabetes 2 morbidity among patients from contrast areas and copper oxide pollution has been stated. Change of electrokinetic activity of buccal epithelial cells at diabetes 2 indirectly reflects an organism functional state.
