Objective:To compare effects of 3 therapeutic

method of calming the liver and suppressing yang

method of resolving dampness and removing turbid

and combination of both methods on vascular remodeling（VR）in spontaneous hypertension rats（SHR）.Methods:SHR were randomly divided into resolving dampness group

calming the liver group

calming the liver and resolving dampness group

Enalapril group and model group

with the Wistar-Kyoto（WKY）rats used as normal control group.They were treated for 8 weeks.Changes of blood pressure

aortic collagen content

and its vascular smooth muscle（VSM）

collagen fibers（CF）

area of elastic fibers（EF）were investigated in all groups.Results:The blood pressure

aortic collagen content

VSM and CF area in the model group were significantly higher than those in other groups（P<0.05 or P<0.01）;and the number of the nucleus of vascular smooth muscle cells（VSMC）in the model group was significantly less than that in WKY group

calming the liver and resolving dampness group

and Enalapril group.There was significant difference between model group and WKY group in changes of EF.Conclusion:All the 3 therapeutic methods have functions of decreasing blood pressure

inhibiting deposition of aortic collagen and overgrowth of VSMC.
