[Ultrastructural morphology of the air-blood barrier and pulmonary surfactant in pulmonary inflammation in experimental alcoholic intoxication].

Combined investigation of ultrastructure of components of air-haematic barrier and surface-active properties of surfactant in 21 guinea pigs' lungs with simulated pneumonia against a background of alcoholic intoxication was carried out. It was established, that alcoholic intoxication aggravates a deficiency of pulmonary surfactant occurred in pneumonia because of its high phagocytosis with alveolar macrophages. The increase of mobilization of alveolar macrophages in alcoholic intoxication may be connected with the rise of surfactant secretion by hyperfunctional pneumocytes of the 2nd type. Stopping of alcoholic intoxication may lead to normalization of qualitative composition of surfactant phospholipids.
