Serum guanase activity was measured using a sensitive colorimetric method in patients with liver diseases. Guanase activity was correlated with GPT, GOT in acute viral hepatitis and chronic hepatitis, however, in liver cirrhosis and hepatocellular carcinoma it was correlated with total bilirubin as well as aminotransferases. In addition, the GPT-to-guanase ratio differed chronic hepatitis from liver cirrhosis. These findings suggest that determination of guanase and aminotransferases in useful in differentiation of liver diseases as well as assessing liver damage.

Antipyrine (AP) clearance was determined in 23 cases with liver cirrhosis (LC), 12 with chronic active hepatitis (CAH), 12 with hepatocellular carcinoma (mcHCC), 20 with non-hepatic diseases and 70 healthy controls. ICG Clearance was performed simultaneously in 9 cases of them. The results showed that AP clearance was significantly decreased in patients with LC and moderately decreased in CAH and HCC, its diagnostic sensitivity in LC was significantly higher than that of GPT. The significant positive correlation between the AP and ICG clearance was noted and AP clearance also well correlated with serum albumin level and prothrombin time. It is suggested that AP clearance may be used as a quantitative test to determine the reserve capacity of liver and as a substitutive test for ICG clearance.

Uncontrollable change of diabetes mellitus (DM) has occurred in one of our patients who had received hepatic arterial embolization (HAE) for hepatocellular carcinoma (HCC). This prompted us to examine the influence of HAE to the diabetic patients with HCC. Thirty-four patients accompanying DM who had received HAE were examined fasted blood glucose (FBG) and the liver function before and after the procedure. HAE was performed using Gelatin Sponge and Lipiodol containing anticancer agents, either alone or combined. Of 34 patients 6 showed increase of FBG level of more than two times after HAE. The FBG level had a tendency to elevate as the grade of DM advanced. The tendency was also recognized on pre-HAE oral glucose tolerance test. However, FBG elevation had no relation to the changes of liver function (GPT, Choline Esterase), the difference of embolic materials and pre-HAE status of DM control. From the results, one must be aware that HAE or Lipiodol infusion to diabetic patients with HCC sometimes may cause uncontrollable change of DM, especially in case of advanced DM patients. Consequently, careful follow-up of HCC as DM is advisable for improvement of the patients' prognosis.

HCFU was orally administered to 14 patients with hepatocellular-carcinoma, (including 11 patients with liver cirrhosis) and evaluated of HCFU and 5 fluorouracil (5-FU) levels. Blood and tissue 6-8 hr. after oral administration. The concentration of 5-FU in tissue was almost in the effective levels. In addition, the 5-FU level in the tissue of hepatocellular carcinoma tended to be higher than in non cancerous portion of the liver. 5-FU tissue concentration was not correlated with various laboratory data for the liver function (K-ICG, T. bil, GOT, GPT, etc.) From these results, it is suggested that HCFU is a useful anticancer agent for hepatocellular carcinoma especially for the cases accompanied liver cirrhosis.

The purpose of this study was to evaluate the clinical diagnostic value of serum total bile acid (STBA) in hepatobiliary diseases. Fasting STBA was measured using the enzymatic colorimetric method in 44 normal control cases and 153 cases of hepatobiliary disease, and then abnormal rates were compared to other conventional liver function tests. These 153 cases of hepatobiliary diseases included acute viral hepatitis (10 cases), chronic persistent hepatitis (32 cases), chronic active hepatitis (16 cases), liver cirrhosis (15 cases), alcoholic hepatitis (11 cases), alcoholic fatty liver (23 cases), alcoholic cirrhosis (17 cases), chronic liver diseases with slight fatty changes (10 cases) and hepatocellular carcinoma (6 cases). Except for 8 cases of acute viral hepatitis, the above cases were verified by liver biopsy. There were also 13 cases of biliary tract diseases. Fasting STBA and other conventional liver function tests were used in the above hepatobiliary diseases during the acute, exacerbated or decompensated stage, and the stable or compensated stage, and their abnormal rates compared. The results of this study revealed that the concentration of STBA is raised in various hepatobiliary diseases, which is related to the degree of hepatic cell injury and the various stages of liver. The concentration of STBA was higher in the acute, exacerbated or decompensated stage than in the convalescent, stable or compensated stage of liver diseases. When the abnormal rates of STBA were compared to other conventional liver function tests, the abnormal rates of STBA were not inferior to r-GT, GOT and GPT, and were more accurate than the other liver function tests.(ABSTRACT TRUNCATED AT 250 WORDS)

We assayed serum levels of certain enzymes and tumor markers in patients after transcatheter arterial embolization (TAE) to evaluate the effectiveness of this treatment. Twenty patients had hepatocellular carcinoma and two patients had metastases to the liver from colon cancer. Assays were first done immediately after TAE and were continued for the next 12 days. Glutamic oxaloacetic transaminase (GOT; EC 2.6.1.1, L-aspartate:2-oxoglutarate aminotransferase), glutamic pyruvic transaminase (GPT; EC 2.6.1.2, L-alanine:2-oxoglutarate aminotransferase), and lactate dehydrogenase (EC 1.1.1.27; (S)-lactate:NAD+ oxidoreductase) peaked 24 to 48 h after TAE and returned to the base lines in 7 to 10 days. Mitochondrial GOT (mGOT) and glutamate dehydrogenase (GLDH; EC 1.4.1.2, L-glutamate:NAD+ oxidoreductase) also peaked at the same time after TAE. alpha-Fetoprotein peaked 2 h after TAE and decreased to half of the baseline on day 7. Carcinoembryonic antigen peaked at 24 h and fell at 48 h only in the patients with colon cancer. The total amount of cytosolic GOT, GPT, mGOT, and GLDH released was correlated to the volume of the necrotic mass estimated by computed tomography scans. The correlation coefficients for mGOT and GLDH were r = 0.919 and r = 0.939 (both p less than 0.001), respectively. Assays of mGOT and GLDH may be useful to estimate the volume of the necrotic mass of a hepatoma or metastatic carcinoma in the liver.

We assayed type III procollagen peptide in the sera of 213 patients with various liver diseases and 23 normal controls by radioimmunoassay. The non-cancerous limit of the serum level of type III procollagen peptide was defined as the mean +/- 2 SD of the patients with chronic hepatitis, liver cirrhosis and alcoholic liver disease; it was 50 ng/ml. The percentage of type III procollagen peptide in sera exceeding this limit was 22.2% in patients with hepatocellular carcinoma and 17.4% in metastatic liver cancer. Only patients with liver cirrhosis accompanied by alcoholic hepatitis exceeded this limit. In patients with hepatocellular carcinoma with peptide concentrations above 50 ng/ml, the serum level of GOT, GPT, LDH, T. Bil., LAP, gamma-GTP and T. Chol. was significantly higher than in patients with hepatocellular carcinoma whose serum peptide level was below 20 ng/ml.

A 57-year-old man with hepatocellular carcinoma with left thigh-bone metastasis is reported. He was admitted to the hospital with left leg pain. A diagnosis of bone metastasis of unknown origin was based on X-ray films. Physical examination revealed hepatomegaly. Liver function tests showed a slight increase of alkaline phosphatase, GOT and GPT. In serological tests, the levels of alpha-fetoprotein and carcinoembryonic antigen were high. HBs antigen was negative. From the above data, hepatocellular carcinoma was diagnosed.

Assay conditions of human liver glutathione S-transferase and its activity in human serum from liver disease patients were investigated. One mmol/l reduced glutathione, and 1 mmol/l-1-chloro-2,4-dinitrobenzene, pH 6.5, were used for the measurement, because of the very low non-enzymatic conjugation. Glutathione S-transferase activity was inhibited by bilirubin, but this inhibition was counteracted by the presence of a low concentration of albumin. The normal human serum glutathione S-transferase activity was 5.2 +/- 2.4 I.U./l (mean +/- S.D.), and was not influenced by any differences of age, sex or leukocyte count. A significant increase in serum enzyme activity was noted in cases of acute hepatitis with GPT exceeding 200 I.U./l, primary hepatoma and metastatic liver cancer. Some of the cases with fulminant hepatitis showed extremely high values. The degree of correlation between serum glutathione S-transferase and GOT or GPT was high in acute hepatitis, with GOT or GPT exceeding 200 I.U./l, in fulminant hepatitis, primary hepatoma and gall stones, while in chronic hepatitis and liver cirrhosis it was low. In cases of acute hepatitis and fulminant hepatitis, the disappearance of serum glutathione S-transferase from the blood was much faster than that of GOT and GPT. Serum glutathione S-transferase measurements will provide new and unique information for the diagnosis of acute liver diseases.

1. The expression of twelve liver-specific enzymes was analysed in twenty-one independent rat hepatoma X human somatic cell hybrids, and in some cases up to forty-one subclones were also tested. 2. Seventeen hybrids continued to express most of the rat liver-specific enzymes and in some cases human isozymes of glutamate-pyruvate transaminase, alpha-glycerophosphate dehydrogenase, guanine deaminase, alcohol dehydrogenase and pyruvate kinase were clearly identified. 3. Analysis of the segregation of the human liver-specific enzymes in these hybrids led to the assignment of human GPT to chromosome 8 (previously reported, Kielty, Povey & Hopkinson, 1982) and suggests the assignment of human GPD1 to chromosome 12. 4. The expression of the various liver-specific enzymes in these hybrids appeared to be controlled by independent regulatory mechanisms. 5. Four unusual reverse segregant hybrids were also analysed, and in these no liver-specific enzyme activity was demonstrable.
