| Outline of Final Research Achievements |
In order to investigate the mechanisms of pulmonary emphysema and approach to the therapy, we tried to build a rat model of emphysema caused by cigarette smoke extract (CSE). Six-week-old male SD rats were intraperitoneally injected CSE once a week, and the lung tissues were sampled and examined after 3 weeks of the injection. In comparison with those of control group, there were no significant destruction of the alveoli of rats with injection of CSE, although the enlargement of airspace was observed. Then, we tried to build the rat emphysema model by human umbilical cord vein endothelial cells (HUVEC). A single dose of HUVEC was injected into the peritoneal cavity of 6-week-old male SD rats. The lung tissues were sampled and examined for emphysema formation after 3 weeks and 6 weeks, respectively. However, in comparisons with those of control group, there were no significant enlargement of the airspace and no destruction of the alveoli in the rats with injection of HUVEC.
