目的 :几种经皮冠状动脉血管成形术后再狭窄动物模型均表明 ,电离辐射对动脉损伤后新内膜的增生有较强的抑制作用 ,这一观点最早被认为和平滑肌细胞有丝分裂活性降低有关。本研究用于评价血管 β内照射对动脉壁平滑肌细胞密度及凋亡的影响。方法 :利用 Baum gartner技术获得高
PURPOSE: Several animal models of restenosis after percutaneous transluminal coronary angioplasty have shown that ionizing radiation has a strong inhibitory effect on neointimal hyperplasia after arterial injury, a concept previously thought to be associated with a decrease in mitotic activity of smooth muscle cells . This study was designed to evaluate the effect of intravascular β-irradiation on arterial wall smooth muscle cell density and apoptosis. Method: Get high using Baum gartner technology
