[Structure in air-blood barrier in experimental pneumonia and chronic alcohol intoxication].

Ultrastructural changes were studied in components of the blood-air barrier in pneumonia in the presence of chronic alcoholic intoxication under exposure to a substitution surfactant therapy. The data obtained suggest to us that use of a replacement surfactant therapy promotes reduction of edematous events and dystrophic-and-destructive changes in cells of the parenchyma of the lungs increasing the functional activity of alveolar macrophages and type II alveolocytes.
