To observe the effect of Maishu on blood lipid and vascular endothelial function in golden hamster with hyperlipidemia. Methods:The model of golden hamster with hyperlipidemia was induced by a high fat diet and administrated with MaiShu (low dosage:1 g/kg/d,middle dosage:2 g/kg/d,high dosage:14 g/kg/d). Changes of serum TC,TG,HDL-C and non-HDL-C levels were observed after 2,4,8weeks treatment. Serum VLDL,LDL and HDL were separated by FPLC technique after for 8-week treatment and the level of cholesterol in VLDL,LDL,HDL; testing liver index and TC,TG level in liver were tested. The viscosity of whole blood was measured by the automatic blood viscosity meter. The changes of the endothelium-dependent relaxing reaction of golden hamster mesenteric arteriolar induced by acetylcholine was observed to assess the effect of MS on vascular endothelial function. Results:MS high and middle dose have the function to decrease serum TC level of hamster with hyperlipidemia after 2,4,8 weeks treatment (P<0.01,P<0.01,P<0.05,P<0.01,P<0.01,P<0.01) and the TC level in serum VLDL,LDL,HDL (P<0.05,P<0.01). It also can lower the TC ( P<0.01,P<0.05,TG level in hamster liver,inhibit liver index (P<0.01,P<0.05),improve the whole blood visocity of middle cut (P<0.01,P<0.05) and high cut (P<0.05,P<0.05). Middle dose of MS can also improve the vasodilation function of mesenteric arteriolar in golden hamster model with hyperlipidemia. Conclusion:MS has the function of improving blood lipid,whole blood visocity and vascular endothelial relaxation function in hamster with hyperlipidemia. |
