【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。更多还原

【Abstract】 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.更多还原
