title: [Effects of welding dust on morphology of the bronchopulmonary system and heart in experimental animals].
abstract: A comparative study was made of the action of 5 intratracheally introduced dusts (of manganese, silicon, potassium, natrium, calcium, fluorine, and iron) on the cardio-respiratory system. A more marked biologic activity of the hard component of welding aerosols with a high content of fluorine, potassium and soluble manganese compounds was established. This was proved by structural damages, such as atelectasis, emphysema, bronchiectasis in the lungs, dystrophic developments in the contractual myocardium, a sharp decrease in the luminescent intensity of the adrenergic terminals in the myocardium. All the welding dust samples did not display a fibrogenous activity in any degree.
