The activity of GOT, GPT, APh, liver APh, gamma GTP, AAP and serum cholinesterase were determined in 80 patients with chronic liver diseases, diagnosed clinically, laparoscopically and by liver biopsy. Out of the patients with liver cirrhosis (51), those with portal cirrhosis (40) have a considerably higher activity of gamma GTP, intestinal APh than the patients with postecrotic cirrhosis (11). Cholinesterase activity is markedly lower in patients with cirrhosis and ascites than in the patients without ascites. With the histological data about the activity gamma GTP and GOT are considerably higher without activity. Examinations were carried out also upon patients with chronic aggressive hepatitis (4), chronic persisting hepatitis (9), liver cancer (12) and liver steatosis (4). The data revealed that the majority of the enzymes are with a higher sensitivity (especially gamma GTP, GOT, liver APh, cholinesterase) but with more restricted diagnostic and differential-diagnostic potentialities in view of the great dispersion of the enzyme activities with the separate liver diseases.

Serum activities of LDH isoenzymes as well as total LDH, GOT and GPT were determined after hepatic artery ligation in five patients with primary or metastatic liver cancer. Transaminases and total LDH activities were raised after the operation showing their peaks on the first or third postoperative days. LDH2, LDH3 and LDH5 increased substantially during the first three postoperative days. These changes became nearly normalized within two weeks after hepatic artery ligation. As control the same enzymatic activities were measured in eight patients after usual laparotomies but no significant abnormalities were observed postoperatively. Thus, liberation of not only cathodic but also anodic migrating LDH isoenzymes seems to ensue possibly after acute liver damage induced by hepatic artery ligation. This study also suggests that serial determination of LDH isoenzymes as well as its total activity could be a valuable assessment for evaluating the anti-tumor effect of hepatic artery ligation.

Patients with decompensated liver cirrhosis (n 1441) and those with post-transfusion hepatitis (n 343), whose medical expenses were subsidized by the Aichi Prefectural Government, were followed up for three years by record linkage with the Aichi Cancer Registry. During the follow-up period, 122 incident cases of liver cancer were identified. Compared with the general population, patients with decompensated liver cirrhosis were at a 64.9 times greater risk (50.5 times in males and 100.4 times in females) and those with post-transfusion hepatitis were at a 9.4 times greater risk (8.9 times in males and 13.7 times in females) of developing liver cancer. Information on prognostic factors for 1,068 patients with decompensated liver cirrhosis was also collected in a questionnaire survey by the physicians in charge. Patients positive to hepatitis B surface antigen (HBs Ag) and those positive to HBe Ag had a significantly increased risk of subsequent liver cancer. The risk of developing liver cancer was positively associated with base-line levels of GPT and AFP and age and, inversely associated with total alcohol intake and female sex. In multivariate analyses, the associations with HBe Ag, AFP, sex and age remained statistically significant, whereas the associations with GPT, total alcohol intake and HBs Ag were of borderline significance.

In Okinawa prefecture, prevalence of hepatitis B surface antigen (HBsAg) among blood donors is 3.5% and is twice as high as the average for the whole of Japan (1.5%), and is the highest in Japan (p less than 0.005). In contrast, mortality rates of both liver cirrhosis (LC) and primary liver cancer (PLC) in Okinawa are the lowest in Japan. Many epidemiological studies have shown that the positive rate of HBsAg correlates with mortality rate of PLC. To elucidate the cause of this epidemiological discrepancy, cross-sectional seroepidemiological studies and a prospective clinical study were conducted. In the cross-sectional studies, the following results were obtained; (1) Positive rate of HBsAg among patients with LC in Okinawa was 15.2% and lower than the average for the whole of Japan (23.4%). A similar comparison among patients with hepatocellular carcinoma showed 24.4% in Okinawa Vs. 31.4% in the whole of Japan. (2) The age-specific hepatitis B e antigen positive rate among 829 HBsAg positive health examinees tend to decrease with increase in age; 50% in less than 20 years old age group, 15.7% in third decade and 2-3% or less in 30 or more age group. Of the 829, 431 HBsAg positive subjects were referred our liver out-patient clinic. Then, of the 431, 27 (6.3%) were diagnosed or suspected as having chronic hepatitis and one (0.2%) was diagnosed as having cirrhosis. Of the 431, 381 (88.4%) were diagnosed as healthy HBsAg carrier, the great majority (94.0%) of whom had positive reaction of anti-HBe antibody and normal values of both GOT and GPT.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

Degradable starch microspheres (DSM) have a mean diameter of 45 micron and temporarily obstruct blood flow at the arteriolar (micro-circulatory) level. A new approach was attempted to improve the anticancer effect on non-resectable liver cancer with simultaneous administration of DSM and MMC (mitomycin C) or ADR (adriamycin) into hepatic artery. Three patients with primary liver cancer were treated with DSM (600-1200 mg) and ADR (20-60 mg), and five with metastatic liver cancer were treated with DSM and MMC (10-20 mg). The treatment was repeated two to ten times. Partial or minor responses were observed in 1 out of 3 cases of primary liver cancer and 3 out of 5 metastatic cases. Side effects of DSM were temporary and mild epigastric or chest pain, vomiting, fever, slight dyspnea, etc. A temporary change in the liver functional data (GOT, GPT) was noted in 3 patients. Selective intra-hepatic arterial chemo-embolization therapy with DSM would appear to be beneficial for the treatment of liver cancers with appropriate indications. Cases in which DSM and anticancer drugs were effected were presented in detail.

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.

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.

Mitomycin microspheres (MMC MS), which contain about 5% of MMC and have an average diameter of 45 +/- 8 microns, were administered into the rat hepatic artery in a preclinical study on antitumor treatment for human hepatic cancer. Plasma GOT and GPT activities increased markedly 24 hours after MMC MS injection; they decreased to within the normal range within 3 days of the injection. Hepatic necrobiosis was observed in the area adjacent to the hepatic arterioles containing MMC MS, but was not observed in rats injected with placebo microspheres. The hepatic vein blood of MMC MS treated rats contained a markedly high level of MMC, compared to rats treated in the conventional fashion with MMC. Furthermore, MMC MS remained within hepatic arterioles for over 3 weeks.

In order to confirm the close association between chronic hepatitis B virus (HBV) infection and primary hepatocellular carcinoma (PHC) in Japan, 8,646 male hepatitis B surface antigen (HBs Ag)-positive blood donors (GPT less than or equal to 35 Karmen units) were followed up. Twenty liver cancer cases were observed during the follow-up period (average 6.2 years), the expected number calculated on the basis of age-specific incidence rates among the general population being 3.03. Therefore, the observed to expected ratio of liver cancer was 6.60, that is significantly higher than 1.0. During the same follow-up period, a total of 76 deaths were observed, of which 20 were due to liver cancers and 9 to liver cirrhoses, meaning that nearly 40% of deaths among the study subjects due to chronic liver diseases. Drinking and smoking habits in the liver cancer cases were compared with those observed in healthy male HBV carriers. A strong positive association between drinking habits and liver cancer was observed and there was a significant dose-response relationship after adjustment for cigarette smoking habits. A high risk of liver cancer was also observed among heavy smokers, but a significant dose-response relationship could not be found between smoking habits and liver cancer, partly because of the limited number of the study subjects. These findings suggest that HBV is a major etiologic agent of PHC in Japan where the HBs Ag prevalence rate is about 2%, and alcohol drinking and cigarette smoking may promote the process of HB viral hepato-carcinogenesis.
