Untersuchungen über die serologische Aktivität der Immunglobuline des Bronchialschleims bei chronisch obstruktiven Atemwegserkrankungen

Antibodies against some microorganisms, naturalhaemagglutinins, and organospecific autoantibodies were examined in bronchial secretions of 40 patients suffering from chronic obstructive bronchitis. The determinations were effected in sputa prepared for serological analysis by ultracentrifugation, ultrasonic treatment, and subsequent freeze drying. The lyophilized substance was redissolved in distilled water in a concentration of 100 mg/ml. The results were compared with the values obtained in the blood sera of the same patients.
