[Possibilities of influencing experimental pneumoconiosis and experimental etching of respiratory organs by means of aerosol-inhalations (author's transl)].

The author presented the results of 7 experiments in which he followed with his co-workers the effect of preventively applied aerosol inhalations with rats and rabbits, dusted with quartz or coal dust. Aerosol inhalations of alkaline mineral water "Vincentka" and of salt mixtures, especially of calcium salts affected in some experiments favourably the development of lung dust changes, in other cases on the contrary they did not. The best effect was proved by polyvinylpyridin-N-oxide (PNO). The author described further his experience with aerosoltherapy in persons affected by inhalation of etching substances. Here the inhalation of 10% CaCl2 or Ca gluconicum and of 1% natrium bicarbonicum proved to be the best.
