摘　　要：目的:研究裙带菜膳食纤维对大鼠红细胞膜及血小板细胞膜流动性,为裙带菜膳食纤维利用提供实验依据。方法:将60只正常大鼠分为正常对照组,水不溶性裙带菜膳食纤维低剂量组(5%)、高剂量组(10%),连续30d颈总动脉插管取抗凝血,测定其荧光偏振度ρ、求得微粘度η、细胞膜流动LFU。结果:裙带菜膳食纤维组的血小板细胞膜的流动性明显高于对照组(P<0.05),而荧光偏振度及血小板细胞的微粘度明显低于对照组(P<0.05,P<0.01)。结论:裙带菜膳食纤维可增强大鼠红细胞膜及血小板细胞膜的流动性。Objective： To study the regulative effects of Undaria pinnatifida Sur. dietary fiber on the fluidity of erythrocyte and platelets membrane in rats. Methods： 60 normal rats were divided into normal group, Undaria pinnatifida Sur. dietary fiber low group （5%） and high group （10%）. Samples of blood were collected to determine the indices （ρ,η and LFU） of membrane fluidity for continuous 30 days after insoluble Undaria pinnatifida Sur. dietary fiber had been given to the rats. Results： Undaria pinnatifida Sur. dietary fiber could increase the index of LFU and decrease the indices of ρ and η. Conclusion： Undaria pinnatifida Sur. dietary fiber can enhance the fluidity of erythrocyte and platelets membrane.
