[Phospholipids of pulmonary surfactants and lung elasticity].

Abstract

We discuss the various preparations of substitute pulmonary surfactant that have been proposed for the treatment of Respiratory Distress Syndrome in premature infants. We than submit some experimental results demonstrating that a preparation of phospholipids in an organic solvent can simulate the behavior of the naturally occurring pulmonary surfactant as a monolayer at an air-water interface.
