Many studies have been conducted on the changes of the vessels in the cases of pulmonary tuberculosis. Aoki and his colaborators had observed the dilatation of the bronchial arteries and the swelling of the walls, and estimated the increase of circulation blood. They considered the results to be an important factor of the healing processes.
The conclusions we arrived at, after the examination of the changes of the arteries belonging to the foci, are as follows:
1) The growth of the tuberculous foci is always attended with the proliferation of elastic fibres in the bronchial arteries belonging to them.
2) With the lapse of time, the said bronchial arteries, with the proliferation in the lamina elastica externs and interna, fibrous tubefaction in the intima, and fibrosis around tunica adventitia, developed the symptom of the continuous high blood pressure.
3) The said facts may be interpreted as irrigating currents of the highly exidized blood, due to the increase of the aortal blood in the parts of the foci, have an important factor prompting the proliferation of the interstitial connective tissues.
4) The degree of the proliferation of elastic fibers in the bronchial arteries is equal to that of the atelectasis of the pulmonary organisms around the foci, and that of deposition in them. It has no relation to the size of the individual focus.
