title: Angiotensin-converting enzyme in diseases of the liver.
abstract: Serum angiotensin-converting enzyme activity was measured in various diseases of the liver. Activity increased in progressive order in patients with chronic persistent hepatitis, chronic aggressive hepatitis, and liver cirrhosis. Activity was increased also in patients with acute hepatitis. On the other hand, patients with fatty liver had normal angiotensin-converting enzyme activity and patients with extrahepatic obstructive jaundice showed subnormal activity. Although the mechanism for these enzymatic changes in diseases of the liver remains to be elucidated, serum angiotensin-converting enzyme determination may be useful in the diagnosis of diseases of the liver under certain conditions.
