The prevalence of antibodies against hepatitis C virus (HCV) was investigated in 96 patients with hepatocellular carcinoma, 106 patients with liver cirrhosis without evidence of cancer, and 177 controls without liver disease. 75% of patients with hepatocellular carcinoma had HCV antibodies (anti-HCV), a significantly higher proportion than that observed in patients with cirrhosis (55.6%), or controls (7.3%). The prevalence of anti-HCV was significantly higher in patients with alcoholic cirrhosis and hepatocellular carcinoma (76%) than in patients with alcoholic cirrhosis alone (38.7%) whereas in patients with cryptogenic cirrhosis there was no significant difference between those with and without primary liver cell cancer (81.4% and 77.5%, respectively). These results indicate that HCV infection may have a role in the pathogenesis of hepatocellular carcinoma, even in patients with chronic liver disease apparently related to other agents such as alcohol, and that this recently identified hepatitis virus may be found in a large proportion of patients with cryptogenic cirrhosis.

Serum levels of soluble interleukin 2 receptor were determined in patients with acute viral hepatitis and patients with various chronic liver diseases. In addition, the ability of peripheral blood mononuclear cells of patients with alcoholic cirrhosis to generate soluble interleukin 2 receptor following mitogenic stimulation was studied in vitro. Serum soluble interleukin 2 receptor concentrations in all patients with acute viral hepatitis were found to be significantly elevated (1,319 +/- 527 units per ml) during the first week after onset of disease, as compared to healthy control individuals (375 +/- 102 units per ml; p less than 0.0005) and declined toward normal levels during the course of the illness. Similarly, patients suffering from chronic liver disease such as alcoholic liver cirrhosis (1,172 +/- 507 units per ml), primary biliary cirrhosis (619 +/- 190 units per ml) or chronic active HBsAg+ hepatitis (941 +/- 357 units per ml) showed increased serum soluble interleukin 2 receptor concentrations (p less than 0.0005 vs. controls, respectively). In vitro mitogen stimulation of peripheral mononuclear cells derived from patients with alcoholic cirrhosis resulted in a soluble interleukin 2 receptor production not different from that seen in healthy individuals, suggesting that elevated soluble interleukin 2 receptor serum levels seen in this disease are not the result of an increased synthesis by circulating lymphocytes. Due to the ability of soluble interleukin 2 receptor to bind free interleukin 2--thus making it a potential immunoregulatory molecule--its high serum levels could explain some of the immunologic abnormalities observed in acute and chronic liver disease.

To determine whether alterations of the carbohydrate moiety of human alpha 1-acid glycoprotein constitute a marker of hepatic damage we studied purified alpha 1-acid glycoprotein from healthy individuals and two groups of patients with benign liver diseases: alcoholic cirrhosis and acute viral hepatitis. The results indicate: (1) increased concanavalin A-non reactive forms in cirrhosis and hepatitis, (2) a markedly increased proportion of fucosyl residues in all cirrhotic and some hepatitis patients. Although hyperfucosylation is generally considered to be a tumor marker, the observation here in the two benign liver diseases indicates that an increased fucosyl content should be considered as a more general expression of pathological glycoconjugate metabolism.

The authors collected 41 cases of cirrhosis in native Tibetans with pathological verification. It is found that 60.98% of the cases were alcoholic cirrhosis, with an incidence significantly higher than that of 7.6% reported in the inland (P less than 0.01). 74.19% and 20% of the cirrhosis in male and female patients respectively were alcoholic, while 50% of the cirrhosis in the female were due to malnutrition. Among the Tibetan cirrhotics 12.2% was due to hepatitis and 4.88% each to hydatid disease and tuberculosis. The average age of these cirrhotics was 47.05. The frequent occurring age was between 41-50 (about 41.46%). The Tibetan cirrhosis in peasants and herdsmen were 51.28%. At the first admission, 84.49% got jaundice and 90.2% got ascites. These percentages were higher respectively than 43.2% and 50.5% from the Lanzou report (P less than 0.01). Ascites was serious, portal vein expanded, but splenomegaly were merely 17.07% (normal were 82.93%). These spleens expanded just a little, macrosplenopathy was not found.

From these discussions, it is apparent that: Alcoholic liver disease is increasing at a rapid rate in conjunction with an increase of annual gross and per capita consumption of alcohol. Alcoholic hepatitis and alcoholic hyaline are much less common in Japan compared to western countries. Alcoholic hepatic fibrosis and chronic hepatitis are the common types of alcoholic liver disease in Japan. Alcoholic hepatic fibrosis may be a pathological process or entity independent of fatty liver, alcoholic hepatitis, and alcoholic cirrhosis. It is not clear at the present time whether heavy alcohol consumption per se or non-A, non-B hepatitis virus is the cause of chronic hepatitis seen in HBsAg negative alcoholics.

Morphometric study of liver biopsies from six entities (normal tissue, post-hepatitis cirrhosis, post-alcoholic cirrhosis, cancer-related cirrhosis, hepatocellular adenoma and hepatocellular adenocarcinoma) confirmed that this technique can be a valuable adjunct to histopathologic study in the examination of such specimens. As expected, measurements in cirrhotic nodules showed two populations of cells. The so-called "large dysplastic cells" had nuclear and cellular areas close to those of normal hepatocytes and should thus be considered to be hyperplastic elements, not precancerous elements. The smaller dysplastic cells had morphometric values close to those of the corresponding hepatocellular carcinomas, indicating that these cells are the truly precancerous ones. Therefore, while the study confirmed that hepatic cirrhosis is a precancerous lesion, it also showed that the term hepatocellular dysplasia must be restricted to the smaller type of cells found in such nodules.

In a group of 50 patients with liver cirrhosis compared with a group of 50 clinically healthy subjects serum magnesium levels were determined. The patients were divided according the aetiology of liver cirrhosis and to the presence or not of ascite and cholestasis. The serum magnesium levels were related to the main laboratory tests used in liver cirrhosis. The patients present a significant decrease of serum magnesium levels in comparison to controls. The patients with alcoholic cirrhosis of the liver and with ascite have significant lower magnesium levels in comparison with the patients with post-hepatitis cirrhosis and with patients without ascite. There is a significant correlation between serum magnesium levels and serum levels of aldosterone, albumin, gamma-glutamyl transpeptidase and total pool of bile acids. Direct and indirect effects of alcohol, a secondary hyperaldosteronism, the use of diuretics, and hypoalbuminaemia could account for magnesium serum level decrease in liver cirrhosis.

Nonhuman primates are excellent animal models for human diseases because of their close relationship to humans. Indeed, comparisons of the chromosomes and DNA homologies between primates and humans testify to the commonality of the genetic material between these phylogenetically related species. Not surprisingly, this close relationship at the genotypic level extends to the phenotypic level. Thus, the patho-physiological responses of humans and nonhuman primates to internal and external insults are remarkably similar. Two types of human diseases for which nonhuman primates are paramount animal models are discussed. One type includes diseases with defined, single agent etiologies and to which all members of the species are genetically susceptible. Examples of these are leprosy, AIDS, hepatitis and Parkinson's disease. A second type represents diseases that have a substantial genetic component, but are multifactorial and are greatly influenced by the environment. Examples of these are diabetes, lymphoma, atherosclerosis, alcoholic cirrhosis and anxiety disorders. Nonhuman primates are also ideally suited to the role of animal models in the new area of human gene therapy. In the future, biomedical research will focus increasingly on genetic manipulations such as the transfer of genes from one individual to another to correct genetic diseases, particularly those diseases caused by single recessive gene defects. Before gene transfers are attempted in humans, they should be done in nonhuman primates. In a real sense, nonhuman primates, as animal models, represent the "step to man."

We report 20 cases of alcoholic cirrhosis with superimposed episodes of acute viral hepatitis. Four had acute type B hepatitis and 16, presumed non A non B hepatitis. Before hepatitis, 17 patients had stopped drinking and only four had a complicated cirrhosis. Eighteen patients had received a blood transfusion within the 6 months before the occurrence of hepatitis (mean: 52 days). All patients developed jaundice, 7 encephalopathy, and 5 ascites. The ASAT/ALAT ratio was greater than 1 in 18 patients. Two patients died of hepatic failure. Follow-up was known in 17 of the 18 surviving patients: in all patients jaundice disappeared and transaminases returned to values less than 3 times the upper limits of normal. In our experience, the prognosis is good when viral hepatitis occurs in patients with non complicated alcoholic cirrhosis.

Consumption of the hepatotoxin arsenic is very common in certain geographical areas of India and occurs as a result of the intake of arsenic contaminated water, vegetables, adultered opium, ayurvedic and indigenous medicines, and "home made brew". Arsenic levels were estimated in livers obtained after autopsy from patients of idiopathic cirrhosis, alcoholic cirrhosis, Indian childhood cirrhosis, non-cirrhotic portal fibrosis, fulminant hepatitis and Wilson's disease. Significantly increased levels of arsenic were found in all diseased livers investigated when compared with values obtained from control groups. The study suggests that elevated levels of arsenic may be associated with liver disease.
