The influence of dietary protein content and dietary vitamin B12 supplement on the hepatotoxicity and carcinogenicity of aflatoxin in rat liver was studied. In animals fed a low-protein diet, aflatoxin induced extensive toxic and carcinogenic effects. Cirrhosis was significantly prevented to a certain level by vitamin B12 administration, but the incidence of cholangiofibrosis and hyperplastic nodules was unchanged. No toxic effect was observed in animals receiving high-protein diet with no vitamin B12 supplement in this study (33 weeks). Only one rat bearing a hepatoma was observed in this group. However, hepatoma and hyperplastic nodules were found in the group receiving high-protein diet plus vitamin B12. Cholangiofibrosis and cirrhosis were not observed in the high-protein group regardless of vitamin B12 administration.

Serum albumin and total globulin were determined in 22 healthy people, 29 patients with acute viral hepatitis, 27 patients with cirrhosis and 27 patients with primary hepatocellular carcinoma to see if they might be of discriminating value. The mean serum albumin values were found to be highest in the healthy subjects followed by acute viral hepatitis, primary hepatocellular carcinoma and cirrhosis, in that order. The mean serum total globulin values on the other hand, were found to be lowest in the healthy subjects followed by acute viral hepatitis, primary hepatocellular carcinoma and cirrhosis, in that order. Both the mean albumin and mean total globulin of each group of subjects were significantly different from the respective means of the other three groups. A probable explanation for the higher serum albumin and lower globulin levels found in primary hepatocellular carcinoma, as compared to cirrhosis, is that hepatocellular carcinoma occurs in reasonably well-compensated cases of cirrhosis.

The pathology of the liver in 19 cases of malabsorption is reported. Five of these were proven to have adult coeliac disease, in the others that diagnosis was presumed by exclusion of other causes of malabsorption and by the coincidence of other conditions known to be associated with coeliac disease. Of these cases, three had liver changes of chronic hepatitis and two of these were in the proven coeliac group, including a case with cirrhosis and a hepatoma. In addition, less severe liver changes such as portal tract fibrosis and portal tract infiltration by inflammatory cells were present greatly in excess to that of the controls. The reasons for the occurrence of liver damage in coeliac disease are outlined and discussed in relation to the liver disorders associated with jejunoileal bypass used in the treatment of obesity. Possible mechanisms of liver injury in coeliac disease are described.

A study of the serological markers of Hepatitis B virus (HBV) including e antigen (HBe Ag) and antibody against HBe Ag (anti-HBe) was performed in Senegalese patients suffering from cirrhosis and primary hepatocellular carcinoma, and in a control group (blood donors). It was not possible to diagnose additional HBV infections in primary hepatocellular carcinoma patients using HBe Ag or anti-HBe Ab alone as serological markers. The lower prevalence of HBe Ag among primary hepatocellular carcinoma patients as compared with cirrhotic patients suggests that active replication of HBV becomes increasingly defective during the course of the malignant process.

An autopsy case of a 65-year-old male who died of hepatocellular carcinoma superimposed on liver cirrhosis complicated with systemic sarcoidosis is presented. No organ metastasis of hepatocellular carcinoma was found except for a minute tumor embolus in the left upper lobe of the lung. Involved organs by sarcoidosis were the lymph nodes, lungs, heart, liver and spleen, but its presence was not noticed before death. Its cardiac involvement coincide with his clinical symptom of exertional dyspnea and the ECG finding of A-V block.

Numerous cases of chronic hepatitis have been shown to be closely associated with persistent infection with hepatitis B virus (HBV). A group of 100 patients suffering from chronic active hepatitis (CAH) was investigated for HBV serologic markers. Of these, 35 patients were HbsAg-positive; in 26 HBsAg-negative subjects, anti-HBc were detected using counterimmune electrophoresis and complement-fixation tests. These data suggest that chronic liver disease in patients who were only anti-HBc-positive might be related to persistent infection with hepatitis B virus. Epidemiological clinical and histopathological data were different when we compared CAH patients who were HBsAg-negative, but anti-HBc-positive, with HBsAg-positive CAH patients. A sequence is proposed leading from HBsAg-positive to HBsAg-negative CAH, cirrhosis, and hepatoma in temperate areas, according to a model similar to the one described in intertropical Africa.

An attempt was made to elucidate the pathogenesis of hepatoma. The material comprises 20 cases which were followed up more than 3 years after diagnosed liver cirrhosis and verified by autopsy. Hepatoma was found in 10 out of these 20 cases (50%). The follow-up period of these 10 cases with hepatoma was from 3 to 9.5 years (the mean value; 5.5 years). All 10 cases were not heavy drinkers, and showed liver cirrhosis of the mixed type by autopsy. HBsAG was positive in 6 out of 8 cases by RIA method (75%), and alpha-f was also detected in 5 of 7 cases by RIA method (70%). On the contrary, only 2 out of 10 cases without hepatoma were HBsAG positive (20%). The present results indicate that HBsAG positive liver cirrhosis of the mixed type is closely related to hepatoma in our country.

Three hundred and eighty-five patients mostly with chronic liver diseases and 729 apparently healthy adults were studied for hepatitis B surface antigen (HBsAg) with reversed passive hemagglutination and antibody (anti-HBs) with passive hemagglutination. In healthy adults around 15% was HBsAg positive and in 45% was anti-HBs positive, estimating hepatitis B virus (HBV) infection in nearly two thirds of the population. The infection already occurred before adulthood. The prevalences of HBsAg were invariably over 80% in chronic hepatitis, cirrhosis and hepatocellular carcinoma (hepatoma) indicating an intimate relationship to HBV. On the contrary, the positive rates of anti-HBs in these diseases were far lower than those in healthy people and patients with other diseases, this is similar to the situation in chronic HBsAg carriers. The prevalence of HBsAg in hepatoma patients was unusually high, being 82.7% in contrast to 11.9% in patients with other malignancies. Not only hepatoma patients with cirrhosis but also those without cirrhosis were found to have high prevalence of HBsAg. The fact indicates an even more intimate relationship between hepatoma and HBV.

Obstructive jaundice, pruritus, and malabsorption developed in twin brothers in infancy. Early liver biopsy specimens showed intracellular and canalicular cholestasis with normal bile ducts. By the age of 3 years, both had cirrhosis and portal hypertension. Each died during the teen years from hepatocellular carcinoma. These brothers represent the tenth reported family with familial cholestatic cirrhosis, and they are the first patients with this syndrome in whom hepatoma developed.

An analysis of 294 patients who died with cirrhosis showed that 24% had developed hepatocellular carcinoma. Haemochromatosis and HBsAg positive chronic active hepatitis were high risk groups (36% and 42% respectively) and the frequency was lowest in primary biliary cirrhosis and HBsAg negative chronic active hepatitis (3% and 11% respectively). Those with hepatocellular carcinoma showed a striking male preponderance (11:1) and further analysis has shown that the proportion developing this tumour in each group was closely related to the proportion of males in that group (r=0.97). Age was the only other significant factor, malignant change occurring more commonly in those over the age of 50 years than those below (30% and 7% respectively, P less than 0.005). The indluence of HBsAg was largely accounted for by the known predisposition of males to carry HBsAg. The group of patients who had developed this tumour without cirrhosis were younger (mean age 39 years) and had a lower male to female ratio of 1.1:1 and the place of contraceptive-related tumour within this group is dicussed.
