Abstract

Objectives:We have reported that oral administration of Saiko-ka-Ryukotsu-Borei-To (SRB), a traditional Chinese formulation, inhibited the intimal thickening in carotid artery after balloon injury in cholesterol-fed rats. To elucidate its mechanism, the effects of SRB on migration and proliferation of vascular smooth muscle cell (VSMC) were examined in vivo and in vitro.Methods: < In vivo-study> Rats were fed on diet containing 1% cholesterol and SRB 3 days before and 4 days after denudation. Simvastatin was used as a positive control. (omitted)
