CHARACTERISTIC OF RESPIRATORY SYSTEM COMPENSATORY-ADAPTIVE REACTIONS IN MILITARY MEN OF SPECIAL TASK UNITS IN DYNAMICS OF SERVICE AND FIGHTING TASKS PERFORMANCE
Gudkov A.B., Beskaravainy E.B., Popova O.N., Sarychev A.S.
Abstract
There have been studied separate compensatory-adaptive reactions of the respiratory system in 39 military men of special task units in dynamics of service and fighting task performance. It has been established that organism’s abilities of adaption to organization of necessary functional structures with its stable preservation in optimum state resulted in development of compensatory adaptability of the military men’s respiratory system regardless of the length of their service. The received results allowed to suggest dependence of compensatory- adaptive reactions of the military men’s respiratory system on the nature of the service and fighting tasks performance with possibility of full recovery at the end of 1 month after the return of the military men to the permanent base without carrying out of additional rehabilitation measures.

FORMATION OF OROPHARYNX MICROBIOCENOSIS IN PREMATURE INFANTS WITH LOW AND EXTREMELY LOW BODY MASS AT BIRTH IN CONDITIONS OF A CHILDREN’S HOSPITAL
Malygina O.G., Bazhukova T.A., Simonova G.V.
Abstract
There has been conducted a bacteriological study of upper air passages secretion in 58 premature children with body weight less than 1 500g on admission and discharge from the Department of Pathologies of Newborns and Premature Children of the Vyzhletsov Arkhangelsk Children's Hospital from October 2009 till June 2011. On admission to the Department, all the children showed poor microfloa of the oropharynx, it was represented by the coccal flora. During the period of hospitalization in the hospital, the oropharynx microecology was formed by obligate representatives, but there was also registered colonization by pathogenic and opportunistic pathogens. The upper air passages microflora formation was affected by the following factors: artificial pulmonary ventilation, type of infant feeding, correction with probiotics and intrauterine contamination. In the premature infants with low and extremely low body mass at birth in conditions of a long-term stay in the hospital, microbiocenosis of the oropharynx mucosa was not formed adequately.

PECULIARITIES OF EEG AND DC-POTENTIAL OF THE BRAIN IN NORTHERN SCHOOLCHILDREN
Dzhos Y.S., Nekhoroshkova A.N., Gribanov A.V.
Abstract
The article has presented the results of a study of the brain bioelectrical activity and cerebral energy exchange in 60 northern children aged 9-10 years (30 boys and 30 girls). Functional state of the central nervous system was assessed with use of electroencephalography and the method of the DC-potential recording. The results indicated that age development of the northern schoolchildren occurred in connection with adaptation to a complex of severe factors of the North and was characterized by lower frequency of alpha-rhythms and a higher level of theta - and delta-activities, especially in the frontal areas. It was accompanied by higher energy consumption of the brain in general and reduction of energy consumption in the frontal areas of the northern children compared to their peers in the central regions of Russia. These facts indicated relative immaturity of the brain and manifestations of functional stress associated with impact of adverse climatic and environmental conditions of the North on the children.

COVERAGE OF PREFERENTIAL POPULATION GROUPS FOR ANTIHYPERTENSIVE MEDICINES IN ALMATY, KAZAKHSTAN
Abuov D.Z., Grjibovski A.M., Kalmantaeva Z.A., Stepkina E.S., Rustemova A.S.
Abstract
The aim of this descriptive study was to assess the coverage of preferential population groups for antihypertensive medicines in Almaty, the former capital of Kazakhstan. We present the data on the coverage of preferential population groups for the period from 2008 through 2012. The absolute number of residents who were covered for antihypertensive medicines increased from 31814 to 73518. Financial resources allocated by the state to cover the privileged population of Almaty for antihypertensive medicines increased from 28 188 714 KZT (233 423, 86 USD) in 2008 to 223 050 004 KZT (1 492 720,67 USD) in 2012 which corresponds to per capita increase from 7,34 USD in 2008 to 20,3 USD in 2012. The next step which we plan to make in a few years from now is to assess whether these measures has led to decrease in mortality from hypertension and from diseases of circulatory system in general.

EPIDEMIOLOGY OF ADOLESCENT PREGNANCY
Laryusheva T.M., Baranov A.N., Lebedeva T.B.
Abstract
The review has summarized the present knowledge reflecting urgency, incidence and causes of pregnancies among adolescents, their reproductive preferences and attitudes to contraceptive methods. A social portrait of adolescent pregnant girls has been shown. Statistical data have been given on choices of minors in pregnancy; adolescents’ attitude to abortions, social and psychological aspects contributing to abortions, as well as features of clinical course of pregnancy, delivery and perinatal outcomes in this age category.

SYNERGETIC BIOPSYCHOSOCIOSPIRITUAL CONCEPTION OF RHEUMATOID ARTHRITIS
Sidorov P.I., Sovershaeva E.P.
Abstract
Rheumatoid arthritis is one of the most common chronic systemic autoimmune diseases, that primarily affects the peripheral joints with predominant cartilage damage, bone erosion and ankylosis. Despite significant advances in understanding the pathogenesis of the disease and modern biologic disease-modifying therapy, many questions remain open. Chronic and severe course of rheumatoid arthritis, early disability and social dysaptation, demoralization, as well as the high incidence of psychological problems and disorders require development of a multidisciplinary approach to the etiopathogenesis, diagnostics, management, rehabilitation and preventive care.

INFLUENCE OF THE GEOMAGNETIC FIELD ON RECURRENCE QUANTIFICATION EEG INDEXES
Kanunikov I.E., Kiselev B.V.
Abstract
The effect of changes of the geomagnetic field on human electroencephalograms (EEG) has been studied. Based on the fact that the relationship between the characteristics of the geomagnetic field and the EEG was not linear, the method of recurrence quantification analysis (RQA) was used. EEGs were recorded in 16 sites of the left and right hemispheres in three background states. Subjects (10 people) participated in the multi-day studies. 9 recurrence indexes (RR, DET, L, DIV, ENTR, RATIO, LAM, TT, CLEAN) were calculated for each of the 16 EEG sites. The correlation coefficients were calculated for each index with the global and local coefficients of geomagnetic activity. Since each recurrence index showed significant individual dynamics in the course of the series, the data for all 9 indexes were averaged. All EEG recurrent indexes showed a reliable correlation with the geomagnetic activity, and the number of correlations in the left hemisphere was significantly bigger than in the right one. A significant excess in the number of correlations in the left temporal area (T3) compared to the right one (T4) has been found. It has been concluded that the geomagnetic field had the most pronounced effect on the temporal lobes.

Kharkova O.A., Grjibovski A.M.
Abstract
In this paper we describe the use of non-parametric tests for comparisons of two paired samples. The authors present examples of manual calculation of Wilcoxon’s signed rank test and sign test as well as the use of STATA for calculation of the abovementioned statistical tests. We present assumptions for use of non-parametric tests for paired samples and recommendations on how to present the results in scientific publications.
