Trial production of modified Wilhelmy film balance for investigation of surface properties of pulmonary surfactant and its experimental application

研究肺 表面活性物质表面特性的膜 天平的研制与应用

In the present study we measured the lipid peroxide content in plasma and lung homogenate by Yagi 's method and analyzed the composition of surfactant phospholipid and surface activity of pulmonary surfactant by thin layer chrom-otography and by Wilhelmy 's film balance .

本研究用TBA荧光法测定大鼠烫伤后肺组织和血浆脂质过氧化物的含量，用薄层层析法及膜 天平技术测定肺 表面活性物质的磷脂组成与功能的变化。
