[Comparative evaluation of the diagnostic importance of determining 5-nucleotidase and alkaline phosphatase in the blood serum in liver and biliary tract diseases].

Under examination were 186 patients with diseases of the liver and biliary ducts. In patients with mechanical jaundice resulting from cholelythic disease high indices of the activity of 5-nucleotidase and alkaline phosphatase were revealed in 80--85% of cases, in patients with carcinoma of the head of the pancreas--in 100%. The investigation of these tests and blood serum transaminases in dynamics is of great importance for differential diagnosis of diseases of the liver and biliary ducts manifesting themselves by the jaundice syndrome.
