[Level, structure and dynamics of combined forms of occupational diseases among coal miners of Donetsk region].

The authors presented data on levels, structure and dynamics of combined occupational diseases in coal miners of Donetsk region in Ukraine, analyzed possible mechanisms of such diseases.

[Health status of mining technical school students under present ecological conditions of Donets Basin].

The examinations indicated that the students of mining colleges from Donbass showed unfavourable changes in their health status, including those in their immunobiological resistance and functional status. There was a direct relationship between the levels of environmental pollution and the body's changes, i.e.

[The screening assessment indices of body immunological reactivity in young people living in the Donetsk region].

Pupils from the mining-trade secondary schools aged, 17-18 from different towns of Donbass were examined for the state of immunologic reactivity, as evidenced by the peripheral blood content of leucocytes, level of Igs A, M, G, as well as cytotoxicity of blood plasma. The results obtained suggest weakening of immunological reactivity in the examined populations, with the degree of the immunological reactivity impairement being higher in Donetsk as compared with more clean ecological zone Selidovo, which fact suggests a negative influence the complex of harmful environmental factors has on human organism. The above age group warrants further study; there is also the need to devise approaches toward immunocorrecting therapy for such contingents.

[The immune status indices of schoolchildren in the Donetsk region].

With the purpose of studying the impact of ecological health hazard conditions on the juvenile organism, a total of 192 pupils of upper grades from schools in Donetsk, Makeyevka, Mariupol (conventionally a "dirty" zone) and 126 schoolchildren from Artemovsk and Krasnyĭ Liman (conventionally a "clean" zone) were evaluated for the immunological status. Children from the polluted zone demonstrated decreased levels of lysozyme in saliva as well as of glycogen and acid phosphatase in leucocytes, there were also deviations from the norm in the peripheral blood picture. Young residents of Mariupol appeared to have the worst findings.

[The characteristics of the body's functional status and the state of the health of pupils in mining trade schools in an industrial zone].

The article presents results of study into the level of physical development, condition of the cardiovascular-, respiratory-, central nervous systems, immunobiologic resistance of the organism, prevalence of morphofunctional deviations from the norm, and morbidity rates among the students of the mining-trade secondary school (aged 15-18). It has been found out that adverse ecological situation in urban centres of the Donetsk Province together with specific character of training for occupation in coal industry have a marked negative effect on the functional status as well as health status of the adolescents. On the basis of the studies made a complex of measures has been designed to maintain and promote the health of students of the mining-trade secondary schools.

[The prediction of adolescent success in mastering the job of machinery operator in underground installations at an urban vocational-technical secondary school].

Professiographic analysis of the labour in coal mining resulted in the model for forecast of successful vocational education for the machinists of underground installations, and allowed the differential admission to mining special vocational schools to carry out.

[Characteristics of adaptation of adolescents to different conditions of occupational training in coal mines].

The pattern of forming of the adaptational process to occupational-industrial factors of working in a coal mine depending on the conditions of carrying out practical work was determined. It was found out that the adaptation of young boys to the working activity in deep horizons was accompanied by a more marked tension of the functional status and regulation mechanisms compared to working in less deep horizons.

[Current problems of teaching hygiene to students of vocational coal mining schools].

Proceeding from the study of organization of the teaching and production process among students of secondary vocational mining schools it was established that students' physical adaptation, developed to the end of theoretical studies, was rather unstable. Exposure to a number of occupational factors of mines caused stress of regulatory mechanisms at the initial stage of probation that was succeeded by adaptative reconstruction when working in rather shallow mines and by its absence when working in deep mines. Thus, the necessity of hygienic corrections in the teaching process of students of vocational mining schools was underlined.
