Tyramine oxidase activity in needle biopsy of normal livers and diseased livers.
Tyramine oxidase and UDP-glucuronyl transferase activities were determined in 52 diseased livers obtained by needle biopsy. 14 liver specimens were also subjected to acetyl CoA carboxylase determination. Tyramine oxidase level was elevated in livers with nonalcoholic fatty change or toxic hepatitis, and reduced in livers with fibrosis or chronic alcoholic injury. UDP-glucuronyl transferase activity was reduced in livers with severe parenchymal damage or hyperbilirubinemia. Acetyl CoA carboxylase activity decreased markedly in an active alcoholic cirrhotic liver, and was elevated in alcoholic fatty livers as well as in a liver with acute venous stasis.
