Effects of Fas ligand gene on vascular remodeling in rat carotid artery after balloon injury / 介入放射学杂志

ABSTRACT

Objective To investigate the effect of Fas ligand gene on vascular remodeling in rat carotid artery after balloon injury. Methods The rat carotid artery model after balloon injury was performed .Twelve SD rats were randomizely assigned to ① control group Ad ?gal ② FasL group . Fourteen days after balloon injury in situ perfusion fixation was performed with 10% formalin and the carotid artery specimens were obtained . Morphometric analysis were performed. Results FasL significantly reduced intimal area(IA) , increased lumen area (LA) and external elastic lamina area (EEL) Conclusions FasL has the role of promoting favorable vascular remodeling of injuied vessel.
