Distribution of the alkaline phosphatase and
5'-nucleotidase
activity was studied in blood serum by means of gel filtration through Sephadex G-200 with jaundices of different origin. Both enzymes have two forms differing in the molecular weight,
5'-nucleotidase
presenting mainly a high-molecular form in contrast to alkaline phosphatase. This form activity for both enzymes is higher with obturative jaundices as compared to
liver cirrhosis
and virus hepatitis. The results of incubating sera with desoxicholate and the subsequent gel filtration in its presence, as well as polyacrylamide gel electrophoresis of butanol extracts of the fractions containing high-molecular fragments, evidence for the fact that these fragments are lipoproteid complexes.

In 18 horses there was no effect of age or sex on plasma activities of gamma-glutamyl transferase (gamma-GT),
5'-nucleotidase
(5'-NT) and leucine aminopeptidase (LAP). All the enzymes were equally stable after storage for one month at -20 degrees C and there was no significant difference between their activities in serum and plasma in clinically normal horses. The pattern of release of gamma-GT, 5'-NT and LAP into plasma was studied in 114 horses which had a variety of orthopaedic, gastrointestinal, cardiovascular and hepatic (necrosis, lipidosis, neoplasia and
cirrhosis
) conditions. A definitive diagnosis of hepatic disease was established by histological examination of the liver. gamma-GT and 5'-NT were leaked into plasma in hepatic disease and gamma-GT was the more sensitive indicator of liver damage. There was some evidence that gamma-GT and 5'-NT plasma activities may increase in hepatic necrosis as well as in biliary obstruction. LAP was insensitive and not hepatic specific in the horse.

DU-PAN-2 is a high-molecular-weight glycoprotein defined by a murine monoclonal antibody (MAb) elicited against a human pancreatic adenocarcinoma cell line. This MAb recognizes an oncofetal antigen present on the surface of normal pancreatic and bile-duct epithelium, normal bronchus epithelium, and some adenocarcinomas. Elevated levels of the antigen (greater than 400 U/ml) have been detected in the serum of 79% of patients with adenocarcinoma of the pancreas and in a small percentage of patients with other adenocarcinomas, by means of a competition radioimmunoassay. Here, we have studied DU-PAN-2 antigen levels in sera of patients with a spectrum of hepatobiliary diseases and controls. Serum DU-PAN-2 antigen was elevated in 59% of 112 patients with non-malignant hepatobiliary diseases and in 50% of hepatoma patients. None of 50 healthy controls had elevated serum DU-PAN-2 levels. Patients in every category of hepatobiliary disease studied had elevated median serum DU-PAN-2 levels; the highest median levels were seen in patients with primary biliary cirrhosis (1,296 U/ml) and the lowest in stable
cirrhosis
(300 U/ml). Elevated serum DU-PAN-2 levels in one patient with primary biliary cirrhosis and in one patient with hepatoma returned to normal following liver transplantation. Serum DU-PAN-2 levels did not correlate well with alkaline phosphatase,
5'-nucleotidase
, bilirubin, or alpha-fetoprotein. Using an immunoperoxidase technique on formalin-fixed, deparaffinized liver sections, we showed that DU-PAN-2 MAb reacted heterogeneously with bile-duct epithelium but never stained hepatocytes or hepatoma cells. While serum DU-PAN-2 levels may be useful in detecting and monitoring pancreatic adenocarcinoma, they are not specific for this disease.

Patients with jaundice and hyperbilirubinemia over 34 mumol/l have been examined by different methods in order to assess the diagnostic value of the methods. 340 patients were examined clinically and by laparoscopy, 168 patients and 92 healthy persons were examined by 10 laboratory indices, 639 patients--by ultrasonography, 95 patients--by scintigraphy, 116 patients--by computer tomography, 83 patients--by endoscopic retrograde cholangio-pancreatography (ERCPG), 17 patients--by percutaneous transhepatic cholangiography (PTC), 70 patients--by directed liver biopsy. In the patients with cholestasis the
5'-nucleotidase
, alkaline phosphatase, glutamyl transpeptidase (lipoprotein X is positive in 92% of the patients) and cholesterol are increased most. The extrahepatic obstructions are diagnosed by ultrasonography in 94.8% of the patients (the biliary ducts are dilated), in 88.7% of the patients the localization of the obstruction and in 74.7% of the patients the cause of the obstruction are found. In parenchymal jaundice the sonography reveals the disease which has caused jaundice in 62.1% of the patients. The scintigraphy gives correct diagnosis in 50% of the patients with hepatitis and jaundice, in 78% of the patients with
cirrhosis
and jaundice and in 87.5% of the patients with liver cancer. The computer tomography reveals the obstructive jaundice in 94.7% of the patients and the focal processes in the liver in 96.7% of the patients. The ERCPG gives a clear picture of the biliary ducts in 72.28% and of the pancreatic duct in 83.13% of the patients with jaundice, simultaneously the biliary and the pancreatic ducts--in 45.78% of the patients and correct diagnosis in 83.1% of the patients examined.(ABSTRACT TRUNCATED AT 250 WORDS)

The results from the complex study on 26 patients with primary biliary cirrhosis (PBC), 20 females and 6 males, an average age of 46 years, are reported. The most frequent symptoms of PBC are itching, jaundice, hepatosplenomegaly; from the laboratory tests--most characteristic is the increase of serum
5'-nucleotidase
, AP, LAP, gamma GTP, GOT, cholesterol, cholic acid and antimitochondrial antibodies and IgM (AP,
5'-nucleotidase
and antimitochondrial antibodies, being most significant in making the early diagnosis). The laboratory results in PBC are compared with those of the chronic active hepatitis,
cirrhosis of the liver
, liver cancer, extrahepatic cholestasis, with outlining the characteristic differences, depending on the diagnosis. The diagnostic advantages of the various methods are discussed (mainly laparoscopy and liver biopsy) and the histologic and electron microscopic changes of percutaneous transhepatic cholangiography, via echography--81 per cent, laparoscopy--73 per cent, scintigraphy--61.53 per cent and liver biopsy--50 per cent. The results from the treatment with cholestrimine, corticosteroids and azathioprine and surgical treatment, observing a temporary improvement and progressing of PBC, are reported. With the follow-up care of 20 patients, it was established, that 9 had died 5 years, on the average, after making the diagnosis, 11 survived after the 5 years and they are still followed up. The longest survival was reported in two females--11 and 15 years after the onset of PBC.

Some purine metabolizing enzymes of lymphocytes and granulocytes were determined in 13 patients with
cirrhosis of the liver
and in a control group consisting of 18 healthy blood donors. Furthermore cytidine deaminase (EC 3, 5, 4, 5) (CRD) activity was determined in the granulocytes of these patients and in 16 controls. An increase of adenosine deaminase (EC 3, 5, 4, 4) (ADA) activity was found in granulocytes (P less than 0.01) as well as in lymphocytes (P less than 0.01) of the cirrhotic patients as compared to controls. Purine nucleoside phosphorylase (EC 2, 4, 2, 1) (PNP) activity in granulocytes and lymphocytes was identical in the two groups. In lymphocytes of cirrhotic patients decreased hypoxanthine guanine phosphoribosyltransferase (EC 2, 4, 2, 8) (HGPRT) (P less than 0.01), adenine phosphoribosyltransferase (EC 2, 4, 2, 7) (APRT) (P less than 0.02) and adenosine kinase activities (EC 2, 7, 1, 20) (AK) (P less than 0.05) were demonstrated.
5'-nucleotidase
(5'-N (EC 3, 1, 3, 5) activity in lymphocytes of cirrhotic patients was slightly increased, the increase being correlated to the level of serum gamma globulin. Granulocytes from cirrhotic patients showed a decrease of CRD (P less than 0.05). The finding that ADA activity is increased in mature lymphocytes and granulocytes from cirrhotic patients argues against the possibility that increase of lymphocytes ADA activity is a consequence of malignant transformation or immaturity.
