[Dynamics of the antiprotease system and ventilation indicators during treatment of chronic bronchitis]

The relationship between the antitryptic activity of the blood serum, bronchoalveolar secretion and ventilatory indices of the external respiration function in 85 patients with chronic bronchitis in the process of treatment is described. The above findings allow to recommend antibiotics for wide use only in exacerbations of purulent bronchitis while in other clinical variants reduction of drug loads result in increased therapeutic efficiency.
