The results showed that:(1) In COPD group the alveolar walls were broken. The average area of alveolars was 2.46 times as big as the control group, and the average diameter was 1.42 times as compared with the control group. As the diameter of bronchioles was less than 100μm and 100～200μm respectively, the average area of smooth muscle in bronchioles increased to 3.06-fold and 2.13-fold respectively. By electron microscopic, the proportion of Clara cells of respiratory bronchioles in COPD group decreased, the Clara cells were denaturalized, the proportion of Clara cells containing low density secretory granules increased. The airway resistance was 1.84 times while the dynamic compliance was only 70.45% comparing with the control group.
