title: [Significance of bronchospasm in the development of bronchial obstruction in exogenous allergic alveolitis].
abstract: In 22 patients with exogenous allergic alveolitis, VC, FVC, FEV1/VC%, PEF, MEF25, MEF50, MEF75 were determined before and after inhalation of berotec in 1 dose and antrovent in 1 dose. Bronchospasm was detected in 50% of patients. Bronchial spasm was the sole cause of bronchial obstruction in 18.2% of patients and a cause of this disorder in 31.8%. The contribution of bronchospasm to the development of bronchial obstruction was decisive in most patients. In 42% of patients, the proportion of the former in bronchial obstruction amounted to 61-100%.
