Multicenter Study[Influence of intraschool factors on pupils' mental performance and health status].
The study of the intraschool environment in the examined educational establishments has indicated that the sanitary and hygienic conditions of pupils' school stay are characterized by a diversity of disadvantages. The leading factors that have the greatest influence on schoolchildren's morbidity are those associated with the organization of a teaching-and-educational process (36.9%) and with the intraschool environment (28.1%). All the foregoing suggests that a hygienic monitoring system should be set up in each school for the systemic monitoring of pupils' health and for its forming factors.

[Immunological responsiveness in trained and untrained schoolchildren and students during a school year].
Examination of trained (43 skiers) and untrained senior schoolchildren (31 young males); low-order students-skiers (110 girls) and untrained students (17 girls); high-order students-skiers (n=39) and students not going in for sports (n=60) established that in school children and female students of both groups, the cellular and humoral immunogical changes were mainly seasonal: in spring versus autumn, a considerable reduction in the concentration of immunoglobulins (Ig) G, M, and A and circulating immune complexes (CIC) was attended by a significant B-immunity system increase. In the high-order skiers, the time course of changes in immunological responsiveness depended on both a season and a muscle activity regime. In autumn with the start of intensive training loads, the vast majority of immune defense parameters (9/12) were significantly higher in the trained skiers than in the untrained. In spring versus autumn, despite a significant reduction in many cellular and humoral immunological parameters with a considerable increase in the count of T and B lymphocytes in both groups of students, many parameters, in particular the levels of T and B lymphocytes, IgG, and CIC usually remained higher in the sporting students than those in the untrained students of the same age.

[Somatotype-dependent cardiorespiratory system adaption in children and adolsescents in the north-east of Russia].
The authors have revealed the tension of cardiovascular performance in 11-14-year-old children and adolescents with the macrosomatotype (MaS) and a lower bronchial patency in 13-14-year-old adolescents in the winter-spring period. This points to the decreased reserves of the cardiorespiratory system in the teenagers with MaS during their adaptation the environment of the north-east of Russia.

[The cytological status of the nasal mucosa and the buccal epithelium in coal miners].
Sixty-four persons were examined. The examination was undertaken to study the cytomophological parameters of the cells of the nasal mucosa and the buccal epithelium in coal miners. ⋯ Nasal mucosal atrophic changes were observed in 50% of the examined miners. Examination of the buccal epithelium in apparently healthy miners (code 0) and in workers with Stage I anthracosilicosis revealed the increased proportion of microfloral (Streptococcus) contamination by 79% and 3.7 times, respectively.

[Impact of drinking water calcium and magnesium levels on morbidity in the Omsk Region].
Drinking water calcium and magnesium levels were examined for impact on morbidity in a model rural area of a West Siberian region. It was ascertained that there were negative correlations between the water levels of the above elements and the incidence of respiratory, gastrointestinal, and locomotor diseases and positive correlations between the concentrations of calcium and magnesium and the incidence of nervous, urogenital, and eye diseases. It is concluded that by adjusting the findings, the medical care availability factor should be taken into account in the investigations using the health indices calculated on the data from official medical accounts. This investigation has shown the estimation of the drinking water levels of calcium and magnesium as a significant hygienic problem for a model region.
