Graphic analysis of contraction-distension isotherms for pulmonary surfactant monolayers
- 24 Downloads
A new method for analyzing the surface-active properties of pulmonary surfactants is proposed, based on calculating a “local stability index” and then plotting this index as a function ofS/S o, whereS o andS are, respectively, the initial and contracted areas of the surfactant monolayer formed at the interface. The course of the curves thus obtained allows for reasonably precise and easy comparisons of alterations in the surface-active properties of pulmonary surfactants in response to different factors acting on the body.
