1. Essential for the proliferation of disease bronchiolitis and alveolitis.

2. Results (1) Alveolitis in the model and the Chy-I groups were significantly lower than in the control group, but there was no significant different between the model and the Chy-I groups.

3. The alveolitis that produces fibroblast proliferation and collagen deposition is progreive over time.

4. Objective To analyze the features of Extrimic Alergic Alveolitis on HRCT , and to improve HRCT diagnostic accuracy .

5. Conclusion The imaging findings of alveolitis caused by BLM is of some different characteristic in comparison with that caused by pneumococcus.

6. Extrinsic allergic alveolitis is a lung disorder resulting from repeated inhalation of organic dust, usually in a specific occupational setting.

7. The alveolitis that produces fibroblast proliferation and collagen deposition is progressive over time.

8. Dry Alveolitis is a common complication which occurs after the tooth extraction. It occurs because the wound is not covered by the blood clot so that the wound is infected.

9. Objective: To study the imaging diagnostic criterion for cryptogenic fibrosing alveolitis (CFA).

10. A semiquantitative assay of histological examination, MPO and hydroxyproline in lung tissues were used to determine the severity of alveolitis and fibrosis.

11. These clinical laboratory characteristics were considered to be in conformity with extrinsic allergic alveolitis.

12. Objective To identify high resolution CT features of extrinsic allergic alveolitis and to improve HRCT diagnosis accuracy.

13. The above changes accompanied with lung pathological manifestations, which included acute alveolitis during the earlier period and lung fibrosis during later period.

14. Then some alveolar bone necroses occur. This paper studies the cause and the prevention of Dry Alveolitis in order to find a way to reduce or even eliminate the disease.
