title: Influence of tuberculin on ventilatory parameters in patients with chronic bronchitis.
abstract: The influence of tuberculin administered in aerosol on the ventilatory parameters in patients suffering from chronic bronchitis has been studied. The diameter of the tuberculin skin reaction 1 day after inhalation of tuberculin was found to be related to a decrease in maximal 1-sec forced expiratory volume and maximal midexpiratory flow-rate. Significant decrease in the parameters of dynamic pulmonary ventilation occurred only in a certain proportion (24.6%) of tuberculin-positive patients suffering from chronic bronchitis of the obstructive type.
