[Exogenous fibrosing alveolitis due to the condensation aerosol (smoke) of zinc oxide].

Clinical-and-biological, biochemical, immunological, histomorphological; X-ray and functional examinations of workers of an electric-melting shop manufacturing brass alloys, who had contacts with condensation aerosol with a high zinc oxide concentrations, were used to detect in them pneumoconiosis with the exogenous fibrosing alveolitis (ZEFA). Some workers had acute conditions, i.e.

[B-lymphocyte-related immunoglobulin biosynthesis in workers engaged in the yeasts hydrolysis production].

64 individuals having occupational chronic bronchitis and 41 healthy individuals--both working at yeast hydrolysis production--demonstrated increase in B immunity with higher spontaneous and antigen-stimulated Ig synthesis. The changes were dose-dependent.

[Morbidity among the workers of the hydrolysis yeast production].

Influence of protein-containing dust on the workers results in respiratory diseases. Individuals working in the shops with high level of protein-containing dust in the air of workplace more frequently demonstrate chronic bronchitis and exogenous allergic alveolitis, workers of the shops with low level of the dust in the air of workplace more commonly suffer from bronchial asthma. The authors necessitate adaptation of engineering, technical and medical prophylactic means to lower the morbidity level.

[Work conditions and occupational diseases among the workers of brass and bronze production industry].

Zinc oxide is a main occupational hazard in electrosmelting workshops of brass and bronze alloys. Chronic occupational pulmonary diseases in the workshops are zinc exogenous fibrosing alveolitis among smelters and operators of bridge cranes, silicosis among fettlers of electric ovens.

[Neutrophil chemiluminescence in allergy diagnosis].

A model system is developed for evaluating the sensitization of an organism in vitro from changes in the neutrophil oxygen metabolism. Spontaneous chemiluminescence and that activated by opsonized antigen are recorded. The specificity of the reaction is determined by the degree of neutrophil activation during reaction with opsonized antigen in different concentrations.
