【Abstract】 Objective To observe the effects of Qidan Decoction (QD) on the vascular cell adhesion molecule-1 (VCAM-1) of the abdominal aorta, serum high density lipoprotein (HDL) and serum low density lipoprotein (LDL) in the rabbit with experimental arteriosclerosis, and to investigate the mechanisms of the effects. Methods The rabbit model of arteriosclerosis was induced by feeding a kind of high-lipid feedstuff. Different intervening factors were used to each experimental group. Immunohistochemical techniques were used to detect the expression of VCAM-1, and enzymological techniques were used to detect the levels of HDL and LDL.Results As compared with those in the model group, the expression of VCAM-1 was markedly decreased (P<0.01), the level of serum LDL was significantly lowered (P<0.01), and the level of serum HDL was markedly increased (P<0.01). Conclusion QD can inhibit the development of arteriosclerosis by decreasing the level of LDL, increasing the level of HDL, and inhibiting the expression of VCAM-1 of abdominal aorta.更多还原
