Serum angiotensin converting enzyme (SACE) in patients with atopic bronchial asthma

: The aim of the study was to assess serum ACE (S-ACE) activity in atopic bronchial asthma. S-ACE activity values were determined in 50 subjects (11 blood donors, 39 asthmatics) using the radioenzymatic method with Ventrex Laboratories kits. The authors did not find any differences between asthmatics in clinical remission, not receiving therapy, patients receiving prednisone (mean daily dose 10.0 +/- 2.5 mg) and healthy blood donors. In subjects with exacerbations of bronchospasm (not receiving steroids) S-ACE activity was significantly higher.
