摘要 显微镜下观察PS制剂是由液泡球状和液泡棒状聚集物组成.浓度较低的PS制剂溶液中聚集物数量较少;浓度较大的液体内聚集物数量多,放置在载玻片上的PS溶液经过一段时间干涸后,聚集物内外的水分被蒸发,形成板层状聚集物,经分析本文认为此聚集物可能是卵磷脂的聚集物,或表面活性物质胶团的聚集物,并给出其可能的结构示意图. Observated under the microscope, the pulmonary surfactant (PS) prepara tion consists of the bulb and the stick vacuole aggregation. There is less aggre gation in thin concentration PS preparation while there is mass aggregation in t he thickness concentration PS preparation. After the water in the aggregation pl aced on the carry sheet glass had been evaporated, the aggregation became a shap e of layer, which is possibly lecithin or surfactant glue-mass aggregation. Its picture about molecule structure is given.
