Abstract: Alveolar pulmonary surfactant is a complex of macromolecular aggregates composed of phospholipids and surfactant proteins (SP) that is essential for maintenance of normal lung function. The importance of surfactant homeostasis is recognized in the patients and the animal models with pulmonary disease, although the mechanisms of surfactant ...

Surfactants and the environment
International Journal of Cosmetic Science, 1984SynopsisAs a result of their use in detergents and personal products and their subsequent disposal, anionic surfactants may achieve a wide distribution in the environment. It is therefore important to assess the hazard that this use might present to the environment.In order to do this it is necessary to estimate the highest concentrations which are ...

Surfactant flooding, a proven method of oil recovery from conventional reservoirs, is limited due to its adsorption on reservoir rocks. Surfactant adsorption leads to modification of wetting state of reservoirs, but it is dependent on the type of ...

Clinics in Perinatology, 1993
Based on these metabolic studies of surfactant lipids in term lambs, in preterm lambs not treated with surfactant, and in preterm lambs that have been surfactant-treated, the following is a synthesis of the overall metabolism of surfactant. Preterm surfactant-deficient lungs seem to have all the synthetic and secretory pathways for surfactant ...

Surgical Clinics of North America, 1974
The observed changes in surfactant, the surface-active material which lines the alveoli of mammalian lungs, suggest a secondary effect rather than causation, which is no less important to pulmonary function. In the complex interdependency of many factors permitting adequate gas exchange, it appears that pulmonary surfactant has a significant yet ...

Journal of Applied Physiology, 1982
Pulmonary surfactant reduces the surface tension of the alveolar air-liquid interface, thereby providing mechanical stability and preventing alveolar atelectasis. More than 50% of surfactant is dipalmitoyl phosphatidylcholine, a material that is capable of reducing the surface tension of the alveolar interface to uniquely low values.

The mammalian lung is stabilized by a specialized material, the pulmonary surfactant, which acts by reversibly reducing the surface tension at the air–liquid interface of the lung during breathing. Pulmonary surfactant contains approximately 90% lipid and 10% proteins. Dipalmitoyl phosphatidylcholine, the major lipid component, appears to be primarily

Interest in microbially produced biosurfactants has increased recently, due mainly to their potential as agents in enhanced oil recovery. A variety of microbes and their products have been assessed for their surface-active properties, and it has been suggested that biosurfactants may prove useful in a broad spectrum of potential applications which ...
