Abstract
The regional pulmonary circulatory function on asthmatic lungs and the various factors concerned with them were studied in 92 asthmatic patients and 28 dogs of model of asthma, using pulmonary perfusion scaning in asthmatic attack and non-attack.
1. In asthmatic attack, some regional pulmonary circulatory defects with little variety were seen in all cases and in non-attack, most of those defects were shown the improvement.
2. Those phases were proved on the pulmogram by 133Xe and the findings of scinti-camera.
3. The defects of the regional ventilatory function in attack were seen to be closely connected with the defects of regional pulmonary circulation.
4. Various abnormalities were seen in bronchi and unequal findings were found in pulmonary arterial vessels and capillaries in the model of asthma of dogs caused histamine. They were shown to identify with the findings of pulmonary scintigram.
