Abstract

4 cases of bronchial asthma. 6 cases of pulmonary tuberculosis and a case of pulmonary abscess patients were studied with respect to the maximal expiratory flow rates before. during and after an exercise on the bicycie ergometer. a. The basal maximal expiratory flow rates, the expiratory flow rates, on sitting before beginning of the exercise, were considerably lower in the asthma patients compared with those in the pulmonary tuberculosis and lung abscess patients. b. The relative value of the maximal expiratory flow rates in the bronchial asthma patients were higher than those in the pulmonary tuberculosis and pulmonary abscess patients. c. The relative values of the difference were significantly higher in the bronchial asthma patients compared with those in the pulmonary tuberculosis and pulmonary abscess cases. d. The bronchial asthma patients complained dyspnea and restriction of exercise inspite that the maximal expiratory flow rates were actually raised during the exercise.
