Using EPR spin labelling 5 NS, 16 NS (for fatty acids) and MSL (for proteins), the changes in lipid fluidity and protein conformation in the ghost erythrocyte membrane of rat treated by endothelin have been studied.

• 以大鼠红细胞膜为研究对象，以脂肪酸自旋标记物5NS，16NS插入膜脂，蛋白自旋标记物MSL标记膜蛋白，观察内皮素（ET）损伤后膜脂流动性、膜蛋白构象的变化及金属硫蛋白（MT）抗ET保护生物膜作用。
