title: [Functional role of pulmonary surface-active substances].
abstract: Freshly prepared from the rat lung solution of the surfactant active substances (SA1) accelerated oxygen absorption at the borderline of the phases. The oxidized SA1 solutions produced an inhibitory effect. As suggested, functional role of SA1 in the realization of external respiration is not limited to reduction of surface tension and alveoli stabilization, but also includes participation in oxygen absorption and its transport regulation through the aerohematic barrier.
