[Hygienic evaluation of work activities in employees engaged into open-cast mining and chromium-ore concentration].

Despite contemporary equipment usage on mining enterprises, work conditions are influenced by some hazards.

[Endothelial dysfunction development in miners].

The authors studied vascular endothelium state in coal miners. Findings are lower endothelium-dependent and endothelium-independent vasodilatation, dysbalance of humoral markers--that prove endothelial dysfunction development and remodelling of vascular wall.

[Automated database in analysis of pneumoconiosis prevalence in coal miners].

Using simulator of forecasting dust occupational diseases with automated information system, the authors analysed risk of pneumoconioses development in coal miners.

[Cellular immunity state assessed in bronchial and alveolar lavage for experimental animals exposed to the rubber dust]. / Sostoianie kletochnogo zvena sashchity v bronkhoal'veoliarnom lavazhe u éksperimental'nykh zhivotnykh pri vozdeistvii rezinotekhnicheskoi pyli.

Experiments on 21 rats helped to study influence of mechanical rubber dust on cellular immunity state in bronchial and alveolar lavage, efficiency of Ruvimine for prophylaxis. Findings are that mechanical rubber dust is strongly cytotoxic. Ruvimine administration during the whole experiment demonstrates therapeutic and prophylactic effect and normalizes local pulmonary phagocytosis.
