| 摘 要： | 目的检测兔侧支血管生长过程中各时期巨噬细胞的浸润情况;方法单侧结扎兔后肢股动脉,随后将股动脉结扎的远侧端连到相邻的静脉上造成动静脉短路,另侧为对照组,分别存活2d,1周,2周,4周后处死,用特异性的巨噬细胞抗体(RAM11)免疫荧光组织化学结合共聚焦技术检测侧支血管壁内巨噬细胞的数目及其分布;结果在正常血管,其外膜有少量巨噬细胞的存在,股动脉结扎后2d,侧支血管外膜巨噬细胞的数目增加,并黏附至内皮细胞,结扎1周后,侧支血管外膜巨噬细胞的数目显著增加,中膜有巨噬细胞的浸润,结扎2周后,侧支血管外膜巨噬细胞的数目减少,但仍高于正常血管,结扎4周后,侧支血管巨噬细胞的数目明显减少,跟正常血管情况类似,统计学分析结果表明,在结扎后2d、一周、二周和四周不同的时间,巨噬细胞在侧支血管的分布差异具有显著性;结论侧支血管发育过程中巨噬细胞的浸润和侧支血管的形成密切相关,提示巨噬细胞参与了侧支血管的生长发育。 |

| Abstract: | Objective To detect the change of macrophage invasion during collateral vessel growth.Methods Unilateral ligation in the rabbit hindlimb was followed by connecting the distal part of the ligated femoral artery to a nearby vein, causing artery-vein shunt. The other hindlimb served as control.The animals were killed after survival of 2d, 1week, 2weeks, and 4weeks respectively. The number and distribution of macrophages were detected by confocal immunofluorescence using the specific antibody against RAM11.Resu... |
