Circulating Angiotensin Converting Enzyme (ACE) level, chest X-rays and respiratory function tests were determined in 76 male patients with silicosis. Mean serum ACE in the patients was significantly higher than in 30 healthy controls (129.8 +/- 4 U/ml and 92.4 +/- 22.7 respectively), although individual values were in the normal range in about half of the patients. Enzyme levels were independent of silica dust exposure, X-ray changes, functional lung impairment, age, smoking habits, and presence of chronic obstructive pulmonary disease. However, patients with more severe radiological changes tended to have lower ACE values. Our data confirm that serum ACE level is frequently raised in silicosis, but does not give further information in the evaluation of the disease.

UI MeSH Term Description Entries
D007703 Peptidyl-Dipeptidase A A peptidyl-dipeptidase that catalyzes the release of a C-terminal dipeptide, oligopeptide-|-Xaa-Yaa, when Xaa is not Pro, and Yaa is neither Asp nor Glu. Thus, conversion of ANGIOTENSIN I to ANGIOTENSIN II, with increase in vasoconstrictor activity, but no action on angiotensin II. It is also able to inactivate BRADYKININ, a potent vasodilator; and has a glycosidase activity which releases GPI-anchored proteins from the membrane by cleaving the mannose linkage in the GPI moiety.
