摘要/Abstract

摘要： 利用实验性高脂血症SD大鼠模型观察薯蔓多糖(PSPV)的降脂作用及对脂肪肝的预防和疗效。实验持续8w,每2w采血一次,用试剂盒测定血清中TC、TG、HDL-C的浓度,通过公式计算LDL-C和AI;索氏抽提测定肝脏中粗脂肪含量,石蜡切片、光镜观察大鼠肝脏细胞。实验表明:PSPV能极显著降低高脂血症大鼠血清中TC、TG、LDL-C含量和AI;同时能极显著降低受试动物肝脏粗脂肪含量,并对脂肪肝有显著的预防和疗效。结果:PSPV对实验性高血脂大鼠具有显著的降血脂及预防和脂肪肝疗效作用。

Abstract: Using the hypercholesterolemia SD rats to observe the antilipidemic and preventing and curing effects of fatty liver by polysaccharides extracted from sweet potato vines. The experiment was lasted for 8w. Taking the blood every 2w, and the TC, TG, HDL-C in the serum were measured by reagent box, LDL-C and AI was got from the formula. The raw fat in liver was measured by Soxhlet extracting and the liver cells were observed by paraffin-sections and optical microscope. Result: PSPV could decrease serum TC, TG, LDL-C, AI and the raw fat in liver would vary remarkably. The fatty liver was prevented and cured effectively too. Conclusion: PSPV had very significant effect of antilipidemic and preventing and curing fatty liver on the hypercholesterolemia rats.

Key words: polysaccharides from sweet potato vines (PSPV), antilipemic function, fatty liver
