LUNG SURFACTANTS, COUNTERIONS, AND HYSTERESIS.
The wide hysteresis and low surface tension of lung extracts, as studied on a modified Langmuir-Wilhelmy surface balance, are dependent on the presence of subphase electrolytes. A possible mechanism for the hysteresis and its importance to the exchange of surfactants between the alveolar cell and the alveolar surface film are discussed.
