Abstract
Cytological and bacteriological study on the bronchial secretion has been performed in the cases of chronic bronchitis, acute bronchitis, pulmonary cancer, tracheal bleeding, bronchiectasis, mediastinal tumor, laryngectomized patient, laryngeal syphilis, chronic pharyngitis accompanied by atrophic rhinitis and struma.
The results obtained are as follows:
1) Eosinophilic leucocytes, lymphocytes, histiocytes and erythrocytes gere largely appeared in the cases of bronchial diseases.
2) Eosinophilic leucocytes, lymphocytes and histiocytes were dominant to be appeared in the ceses of chronic bronchitis, however, in the cases of acute bronchitis, histiocyte was not appeared whereas the others mentioned above were present.
3) In the cases of bronchiectasis, there were highly appeared non-epithelial cells in the secretion and pneumococci in the cultured secretion.
4) In the cases of pulmonary cancer, the case of which the tumor appeared in the main bronchus revealed numeraus atypical cells (class 4) whereas the two cases without the tumor in the main bronchus revealed no atypical cells (class 1).
5) In the cases of laryngeal cancer to which laryngectomy was performed there was a few atypical cells (class 2) in the secretion.
