title: Changes in serum succinyltrialanine p-nitroanilide hydrolysing activity in hepatobiliary diseases.
abstract: Serum succinyltrialanine p-nitroanilide hydrolysing activity was elevated in patients with hepatobiliary diseases. The highest activities were seen in acute cholangitis and intrahepatic cholestasis. The change in succinyltrialanine p-nitroanilide hydrolysing activity was closely associated with those in gamma-glutamyltranspeptidase and alkaline phosphatase activities. In some cases, however, the former was more sensitive than the latter.
