JOURNAL FREE ACCESSRoentogenographic findings of 25 cases of pulmonary tumors originated from bronchial glands were discused.
: Carcinoid tumor in 5, Adenoid cystic carcinoma in 2, Mucoepidermoid carcinoma in 2, and Adenocarcinoma pathologicaly diagnosed to be bronchial gland carcinoma in 16 cases. Seven cases of the Tumors, excluding adenocarcinoma, were observed proxymal to the subsegmental bronchi. The extrabronchial invasion were observed less frequent in bronchial gland tumors than in bronchogenic carcinomas.
Radiographically atelectasis and obstructive pneumonitis were promiment features and non invasive findings could be well demonstrated by pulmonary angiograms. Therefore pulmonary angiography can become an useful diagnostic method to distinguish from bronchogenic carcinoma.
Bronchial gland adenocarcinoma tend to originated from more proxymal bronchi than the site of bronchogenic adenocarcinoma, and tend to grow into the lumen of the bronchus.
In case of coin lesion in the periphery of the lung, the shadow shows considerably high density comparing with that of bronchogenic adenocarcinoma and shows less frequent the constriction of the lung structures around the lesion.View full abstractDownload PDF (33599K) -

JOURNAL FREE ACCESSSixteen cases (8 autopsied and 8 resected specimens) of irradiated primary lung cancer have been studied roentgenologically and, morpho-histologically with special reference to the tumour and surrounding tissues using the paper mounted large lung section and microscopy. The purpose of this study is to analyze the roent-genological features of the tumour and thier surrounding tissues and the morpho-histological findings after the cobalt 60 radiation therapy.
The following results have been obtained.
1) Roentgenological findings of the tumour and surrounding tissues show diffuse homogeneous densities consist of resolving localized compressive atelectasis, radiation pneumonia-fibrosis, fibrosis of alveolar septa and secondary infection, metastasis, atelectasis, congestion and hemorrhage in the lung.
2) Linear and bronchial tree like shadows radiated from the tumour to the peripheral lung fields consist of proliferation and fibrotic retracted interstitium of the tumour and fibrotic change of blood vessels, lymphangitis carcinomatosa and indentated thickened pleura.
Finally the changes of cancer cells as a result of irradiation were discussed.View full abstractDownload PDF (18184K) -
(1) The results in case of BleomycinKeisuke Sagawa1975 Volume 15 Issue 1 Pages 41-51

JOURNAL FREE ACCESSInjecting Bleomycin (BLM) into either vein or pleural fluid of dogs in which retention of pleural fluid was artificially made, sequential changes of concentrations in the blood and pleural fluid were measured. On intravenous injection, the concentration in the blood decayed exponentially due to rapid excretion into the urine. Its half time was less than 20 minutes and BLM disappeared from the blood 6 hours after the injection. Even with these rapid changes in both compartments, a definite concentration of BLM was detected in the pleural fluid. On intrapleural instillation, the decay of BLM concentration in the pleural fluid was very slow and its half time was about 9.5 hours after the instillation. With these high concentration in the pleural space, concentration in the blood was kept longstandingly high and the excretion into the urine was very slow. These results suggests that BLM instilled into the pleural fluid filtrated out into the blood in relatively high concentration for long period and may induce an iatrogenic side effect to the lung.View full abstractDownload PDF (1054K) -

JOURNAL FREE ACCESSLung cancer was induced in seven out of ten adult Mongrel dogs by weekly application of 100mg. 20-methylcholanthrene to the right lower lobe bronchus. 20-MC was administered during the period two years and eleven months to three years and ten months, total dosages administered ranging from 12.4 to 19.4g. The tumors were nodular with well defined borders in six cases and infiltrative with ill-defined borders in one. Metastases were seen in the lymphodes of. tracheal bifurcation and paratracheal regions in all cases. Histologic examination revealed squamous cell carcinoma in two, adenocarcinoma in three and adenoacanthoma in two.View full abstractDownload PDF (5077K) -
