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.

Methods Rabbits were randomized to three groups. Complex model group were fed with feed containing 0.5% cholesterol for 3 weeks. At the fourth, eighth and twelfth weeks, rabbits were given injection of lipopolysaccharide (1 μg) at auricular artery, cervical part and fold inguen, respectively. Normal group were fed with normal diet, while High cholesterol group were fed with feed confaining 0.5% cholesterol only. After 16 weeks, vascular tissues were analyzed using morphometric and histological methods, and the sera were checked for cholesterol, LDL-C, C-reaction protein and tumor necrosis factor-α. Results The cholesterol and LDL-C of High cholesterol group were increased, compared to those of normal group.
