[Bronchopulmonary diseases in workers engaged in deep-mined extraction of copper-nickel ore].

Examinations were made in 220 male workers exposed to dust-gas (low-silicon dioxide, nitric oxides, and carbon oxide) mixture, physical exercises, and cooling microclimate on deep-mined output of copper-nickel ore. Twenty-eight per cent of the workers were found to have evolving chronic bronchitis that did not substantially affect the patients' working capacity; 3.2% had chronic obstructive pulmonary disease and 1.4% had asthma that had developed before the onset of professional activity. 32.3% of the examinees were ascertained to have individual clinicofunctional disorders that permit their identification as a bronchopulmonary disease risk group to carry out early preventive and rehabilitative measures.

[Diagnostics and therapeutic approach in clinical remission of chronic bronchitis].

Clinical examination and laboratory tests performed on 708 patients with chronic obstructive and non-obstructive bronchitis (COB and CNB), demonstrated heterogeneous character of the group of these patients in clinical remission. This suggests that it is appropriate to distinguish between the stages of complete and partial remission, implying different tasks concerning treatment and rehabilitation. Remission of CNB is characterized by minimal deviation of clinical and laboratory parameters; functional balance between the lipid peroxidation-antioxidative activity (LP-AA) system and immunity is preserved. At the stage of rehabilitation of these patients the major attention is paid to the general sanitary measures (physiotherapy exercises, climate therapy). The stage of partial remission in COB and CNB is characterized by residual activity of the inflammatory process, a disbalance between the LP-AA system and immunity, most prominent in partial remission of COB. Rehabilitation of these patients, in addition to physiotherapy exercises and tempering of the organism, should include special activity, directed towards the normalization of LP and immunity parameters.
