[Quantitative characteristics of pathomorphologic changes in bronchi and pulmonary artery branches in miners with preroentgenologic stage of anthrasilicosis].
Morphometric studies covered lung tissue of 10 miners exposed to dusty work conditions over 1 to 30 (13.4 +/- 3.6) years, who were considered apparently healthy according to follow-up examinations and died in technogenic accident. Findings are that dysregeneration, hypertrophic and sclerotic changes in respiratory part of lungs, in bronchi and in pulmonary circuit arteries develop simultaneously--that proves common pathogenetic concept of these changes and systemic character of the pneumoconiosis. The results necessitate improved methods to evaluate health state of workers, refined criteria for nosologic diagnosis of respiratory diseases related to dust.
