Comparative Study[Ambient air pollution and its impact on the incidence of respiratory diseases in children].
The increased number of ecological problems in Russia has stimulated the development of methodological approaches to studying a human chemical load under the conditions of an industrial town. The data on mortality in children under 3 years of age, who lived in a developed industrial town, have been analyzed. Comparison of data on ambient air purity and those on the incidence of respiratory disease has established a correlation between environment pollution and the likelihood of diseases in children under the influence of harmful factors.

Comparative Study[Correction of iron and immune deficiencies in students from a higher humanitarian educational establishment].
Examinations of 29 female students of a study medical group have ascertained that daily addition of vitamins (ascorutin, thiamin, riboflavin, pyridoxine, cyanocobalamin, and folic acid) to a diet resulted in a slight enhancement in trace element metabolism and hence in an increase in the intestinal and renal excretion of iron, copper, and manganese. Two-week dietary supplement of vitamins in combination with trace elements (iron, copper, and manganese) caused a considerable retention of iron and manganese concurrently with a higher excretion of copper from the body. At the same time, the higher rate of hemopoiesis and the elevated plasma levels of iron and formed blood elements, and the rise in non-specific responsiveness and physical fitness were more noticeable as compared to their normal values. A significant positive correlation was found between the direct and indirect indices of iron metabolism on one hand and the parameters of natural immunity defense and physical fitness on the other.

Comparative Study[Hygienic characteristics of children's sports-and-playing grounds in Moscow].
The hygienic state of 280 children's sports-and-playing grounds was studied in 9 Moscow okrugs in accordance with the proportion of vandalism and the level of greening, noise, and environmental pollution caused by motor transport. Technogenic load on children on the children's grounds was shown to be higher in Moscow than that in its Region, the levels of dust, chlorine ions, lead, and potassium were 10, 3, 5, and 2 times higher in Moscow than in the region. By significantly decreasing the pollution, the minimum distance of children's grounds from a road or a car park should be 15 m. ⋯ The level noise more than 40 dB caused by motor transport on the children's grounds was noted in 53% of cases. The level of poor greening was directly correlated with that of noise. The problem associated with the durability of constructions for children's grounds (the broken constructions were an average of about 12.5%) may be solved, by using fiberglass materials.

[Risk factors and incidence of dental diseases in children in a large industrial town].
A relationship has been studied between somatic diseases, functional changes, and dental mortality in children living in urban areas having different levels of ambient air pollution. Visceral diseases have been ascertained to contribute to the development or deteriorate the course of various pathological tooth and jaw processes. Systemic diseases change the conditions of formation and maturation of dentins, which makes them less resistant. The relationship between the changes in the somatic and dental statuses of children is more pronounced when the ecological situation is poor.
