Abstract

We encountered two cases of patients who showed vocal cord dysfunction and bronchial asthma. By using an ++astograph , we found that bronchial responsiveness of these ailments differed. In the case of vocal cord dysfunction, bronchial responsiveness to methacholine indicated a false high level by adduction of the vocal cord. Therefore other evaluations including pulmonary function and bronchoscopy were required to distinguish it from bronchial asthma. On the other hand, in the case of bronchial asthma, bronchial responsiveness to methacholine was mild, but life threatening asthmatic attack occurred after inhalation of methacholine. Psychological factors were not neglected in considering both of these cases. Therefore we must consider these results and psychological factors when evaluating bronchial responsiveness.
