Lung surfactants in acute pneumonia

Abstract

Lung surfactant system, according to modern views, is a multicomponent, complex, self-regulating system, in which there are 3 main components: the surfactant itself - a thin lipoproteid film located at the air-liquid interface, hypophase and a cellular component represented by alveolocytes of types I, II, III. Lung surfactant system provides stability of alveoli during breathing, supports normal permeability of aerohematic barrier, participates in regulation of water balance, and has a protective function. Surface-active components of surfactant system are phospholipids, and more precisely their fraction - phosphatidylcholine.
