Rat AAA model was made by perfusion PPE elastase through the abdominal aorta, and the specimen was obtained on postoperativeday 3, 7, 14, 28, respectively. Specific elastic fiber staining was used to observe the disruption of elastic fiber in aortic wall. Immunohistochemistry staining of CD68 was applied to observe the microphage infiltration. The in tisu hybridization and western blot of MCP-1 and MMP-2 were used to study the expression of mRNA and protein. Thus we can analyze the facilitated function of MCP-1 gene to the microphage adherence and infiltration on the earlier AAA.
