There has been studied influence of examination stress on basic parameters of the heart rate variability (HRV) of female students of a northern medical school. 35 students took part in our study. We analyzed statistic and spectral parameters of HRV. Data was analyzed by using the computer software SPSS-17.0 taking into account normalcy of characteristic distribution. A complex analysis of the heart rate basic indexes has detected different contributions in regulation of cardiac activity of the sympathetic and parasympathetic parts of the autonomic nervous system in the students of the medical school. The tone of the sympathetic nervous system was high in conditions of comparative emotional rest in the female students. During the exams the number of the students with predominance of the parasympathetic tone of the ANS which provided a favorable option of anabolic metabolism was reduced. The psycho-emotional stress caused by the examinations led to significant variations of the heart function vegetative support and increased the sympathetic influence.

The basic regularities of spatial migration of natural radionuclides 232Th and 262Ra in the soils of the Arkhangelsk city have been established. The main factors affecting spatial distribution of the natural radionuclides included a type of housing, a geological and geomorphological structure of the territory and a water regime of the soils.

The article has focused on the peculiarities of staple food intake among teenagers and young people in the Arkhangelsk region. It has been found that a choice of products by the young people depends on their self-concept of the anthropometric data. Also, gender factors play a role in the methods of nutrition management. Understanding of the term “sensible nutrition” by the young people as a factor of healthy life depends mainly on their awareness and motivation.

A retrospective analysis of 411 medical records of patients with diagnosed community-acquired pneumonia and treated in an in-patient department in 2010-201 1 has been carried out. Morbidity and mortality data in the Arkangelsk region have been also analyzed. It has been found that the incidence rate and hospital mortality in our region were at the national level and the mortality rate exceeded that. The patients with community-acquired pneumonia were predominantly persons older than 45 years. The proportion of severe community-acquired pneumonia in the hospital was 27 %. Chronic alcoholism accompanied 57 % of the severe pneumonia cases.

The data of the national and foreign authors referring to the pelvic ring trauma as an isolated, multiple and concomitant injury has been analyzed. A comparative analysis of classification, diagnosis, treatment and outcomes among patients with various pelvic injuries has been made.
