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.

The results showed that the influence of the percentage of the needle-shaped fiber on the impact strength of NF-WPC was significant, while much more significant on the bending and tensile properties. The percentage of MAPE influenced significantly to the tensile strength and toughness of NF-WPC. In the conditions of this paper the dimension of wood fiber and the percentage of lubricant paraffin had a minor influence on the mechanical properties of NF-WPC.

To some degree, this study revealed the relationship between ossein and bone miner and the important preventive and therapeutic effects of ossein on OP. It provides theoretical and experimental basis for the research and development of effective prescriptions to cure OP. Limited by the actual experimental situation, we only did some study on the synthesis and content of type Ⅰ collagen. Further study on the changes of decomposition and structure of type Ⅰ collagen are needed to be done.
