肺表面活性物质(pulmcnary surfactant 或Lung surface active material,以下简称PS)是由肺泡Ⅱ型上皮细胞合成和分泌的一种脂蛋白复合物。肺表面活性物质系统(pulmonary surfactantsystem,下称PSS)是指与PS有关的一切生物、生化、生理学过程。它是一个动态概念。 1929年Von Neergaard第一次提出了有关PS的概念,但未引起人们的足够重视。直到50年代Pattle和clements等报道了他们关于PS的研究成果后,PS才引起了人们的极大关注,有关领域的研究工作蓬勃展开。近年来的研究结果表明:PS
Pulmonary surfactant (Pulmcnary surfactant or Lung surface active material, hereinafter referred to as PS) is a lipoprotein complex synthesized and secreted by alveolar type II epithelial cells. The pulmonary surfactant system (PSS) refers to all the biological, biochemical and physiological processes related to PS. It is a dynamic concept. The first time in 1929 Von Neergaard put forward the concept of PS, but did not attract enough attention. It was not until the 1950s that Pattle and Clements reported their research results on PS that they caught the attention of people and the research work in related fields was flourishing. In recent years, the results show that: PS
