Abstract
Pathologic physiological studies concerning to peripheral bronchus and pulmonary cavities have not been as yet fully clarified. Mucous menbrane temperature in peripheral bronchus was measured and the following results were obtained. Catheter type thermistor thermometer was inserted into the peripheral bronchus as deep as it reached to the pleura susing bronchoscope and mucons menbrane temperature of the area was systemically measured. And the distribution of healthy human intra-pulmonary (intra-tracheo bronchial) temperature and the temperature changing area caused by respiratory movement were clarified. The measurement of the temperature of the bronchiol mucous menbrane of the affected region of various pulmonary diseases (such as pulmonary tbc., pneumonia, pulmonary abscess and lung cancer etc.) by the above mentioned technique has been the first attempt in the field. In addition to the above examination, mucous menbrane temperature of Peripheral bronchiol in the affected region which was experimentally caused were also measured. Based on these data, a part of the adjustment of physiology and respiration was explaind. Futhermore, pathologic physiological studies of pulmonary cavities such as temperature, pressure, gasious content of the cavity, histo-chemical pattern and fein structure (electron microscopic figure) of the cavity wall were reviwed from various points. And the following results were obtained: -
Air passage of the pulmonary cavity through communicating bronchus was not always free, but it was made clear that the cavity wall has permeability. The above mentioned experiments have clarified the meanings of the growth of the new blood vessels, composition of the contents, gas in the cavities and excretive mechanism of the contents and so the views of the pulmonary cavities which have been generally believed should be corrected partially.
