Aim :To determine if gypenosides (GPs) could inhibit SMCs proliferation and influence sis gene expressionafter experimental artery deendothelialization. Methods:Both GPs and trapidil were administered before and afterballoon deendothelialization in rabbit iliac artery. Mor-phometry,SMCs actin immunohistochemical staining and sisgene in situ hybridization histochemistry (ISHH) were per-formed on the sections obtained from arterial segments. Re-sults: The intimal hyperplasia and luminal stenosis could befound...
