Patients with pulmonary tuberculosis accompanied by chronic brochitis usually have been treated as pulmonary tuberculosis, because it was vary difficult to diffenrentiate them.
We carried out bronchographies on 150 patients, who had sputa negative for A. F. B. for the last 6 months.
The relationship between bronchographic features and clinical findings was investigated on 54 cases associated with chronic bronchitis out of 105 cases.
The results obtained are as follows.
1) Bronchography must be performed, in order to diagnose chronic bronchitis.
2) On the bronchogram, the characteristic irregularities of bronchial margin were observed in 52 out of 54 cases.
3) The cases with archformed pattern of bronchial margin on the bronchogram were considered to be longer duration of infection, wider affection and cavernous nature than the waveformed pattern.
