A new peritoneoscopic classification of liver surface using a three digit code was developed. The first digit represents the lobular change from normal structure to nodules. The second digit represents the size of the nodule and the internodular distance. The third digit represents the pathological findings, such as inflammation, degeneration, necrosis or regeneration. Furthermore, peritoneoscopic findings of necrosis of lobular size around the portal vein and patchy markings of the liver were presented. These findings were the most prominent in the course of hepatitis progression to cirrhosis.

A histopathological study was carried out on 27 patients with chronic inflammatory liver disease and clinical and/or biochemical evidence of cholestasis who had either mitochondrial antibodies against mitochondrial antigen fractions of 1.19 density ("PBC antigen"; 14 cases) or of 1.13 density ("CAH-PBC mixed-type antigen"; 13 cases). For comparison, the liver biopsies of 17 patients with chronic-aggressive hepatitis (CAH) and antinuclear and/or anti-smooth muscle antibodies but without cholestasis and mitochondrial antibodies, were evaluated. The 14 patients with mitochondrial antibodies against the PBC antigen showed the typical histological features of primary biliary cirrhosis (PBC). The 13 patients with mitochondrial antibodies against the CAH-PBC mixed-type antigen had heterogenous liver alterations. In 11 cases highly active CAH and/or active postnecrotic cirrhosis (AC) were found both with augmented ductular proliferation. Some of these cases showed distinct criteria of PBC as early bile duct lesions or absence of regular bile ducts. The liver histology of one case corresponded to classical PBC; another case to chronic persistent hepatitis. The CAH-patients without cholestasis and mitochondrial antibodies only occasionally showed bile duct proliferation. In conclusion, a high correlation was found between mitochondrial antibodies against the CAH-PBC mixed-type antigen and highly active CAH or early AC with augmented ductular proliferation. This represents an overlapping of CAH and PBC. In contrast, the cases with antibodies reacting to the PBC antigen showed the slowly progressive liver changes of typical PBC.

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.

Ingestion of carbone tetrachloride by male C3H Orleans mice determines an involution of the pineal gland and of the hypophysis, as well as extensive lesions of the hepatic parenchyma. There may exist in these animals a higher blood-level of glucocorticoids, as this has been shown to be the case in men suffering from cirrhosis or hepatitis. Involution of the pineal gland in cases of stress, as has been shown by various authors, would result from an entirely different mechanism, that is by increased secretion of corticoadrenal hormones.

Enzyme deviations in injured livers were studied by analyzing isozyme patterns of phosphorylase using a newly developed electrophoretic method, which separates six molecular species of this enzyme, i.e. M,FM,F,L,L', and FL'. In hepatic injuries caused by CCl4 and galactosamine intoxications of rats, F appeared in early stages and L' (and FL') in later stages of the injuries with a concurrent decrease or loss of L, which is a sole isozyme component of adult liver. In injured livers of patients with hepatitis and cirrhosis of the liver, increases in FL' activity were also found. Appearance of F was found only in hepatocellular carcinoma. The results obtained with phosphorylase isozyme analysis support the idea that an undifferentiated gene expression takes place in the injured livers of non-malignant hepatic disorders.

A mixture with essential and nonessential amino acids high in branched chain amino acids and low in aromatic amino acids (Fischer solution), and another synthetic mixture of branched chain amino acids containing 3 amino acids associated with the urea cycle (Hep-OU) were infused to control subjects and patients with severe hepatic disease. Alterations in serum aminograms, blood ammonia levels and electroencephalograms following the infusion were studied and compared with those obtained by a commercially available amino acid mixture. Short-term or continuous infusion of a commercially available amino acid solution to cirrhotic patients caused an increase in methionine, phenylalanine and tyrosine and a decrease in branched chain amino acids. These post-infusion results were similar to the patterns seen in hepatic encephalopathy. In cirrhotic patients, infusion of Fischer solution which contains small quantities of methionine and phenylalanine produced an increase in the concentrations of these 2 amino acids, probably because of impaired utilization by the injured liver. No marked alterations in serum aminograms, however, were observed in cirrhotic patients either immediately after, or 3 h after, the end of the Hep-OU infusion. Reduction of methionine, tyrosine and phenylalanine levels and elevation of the molar ratio of (valine + leucine + isoleucine)/(phenylalanine + tyrosine) were significant. The infusion of Hep-OU to patients with liver cirrhosis or subacute hepatitis resulted in clinical and neurological improvements and the restoration of the molar ratio of branched chain amino acids/aromatic amino acids.

Alpha-fetoprotein (AFP) is an alpha1-glycoprotein (M.W. about 65000) appearing in the fetal serum of most mammals including man during the early stages of pregnancy; 4 weeks after birth it disappears altogether or exists at very low concentrations as in the normal adult. AFP is formed in the yolk sac, the fetal liver and the gastro-intestinal tract. One of its physiological functions in fetal life is supposed to be the protection of the fetus from maternal oestrogens (oestrophilic property). The clinical significance of AFP is based on the regular and increasing production in primary liver cell carcinoma, less frequently in teratogenetic tumors where it serves as a control of therapy and course of the disease. Less frequent, minor and temporary increases in the AFP serum level occur in several primary tumors with secondary liver involvement, and in inflammatory gastro-intestinal diseases, e.g. of the liver (hepatitis, cirrhosis). AFP has an increasing importance in gynecology (gestational age, fetal distress syndrom, malformations, hydatidiform mole/chorion carcinoma). The physico-chemical properties of AFP are widely known. Both fetal and tumor AFP appear to be immunologically and biochemically identical, as are that of tissue and biological fluids. The differences observed (variants, microheterogeneity) depend mainly on the different content of sialic acid. An antigenetic relationship exists, between the AFP of most species. The immunodiffusion (Ouchterlony) is the most frequently used but relatively insensitive test (1-5 mug/ml) in finding AFP, whereas the radioimmunoassay is the most sensitive one (up to 0,25 ng/ml) and permits the determination of normal serum levels in adults (below 20 ng/ml). The serum concentration in healthy pregnant women lies up to 500 ng/ml, in patients with hepatitis, liver cirrhosis and other liver diseases mostly under 3 mug/ml, whereas in those with primary liver cell carcinoma levels up to and above 600 mg-percent have been found.

Most of the knowledge of post-hepatitic cirrhosis comes from studies performed in the last five years on the hepatitis B antigen-related variety. The position of other types of hepatitis (particularly type A) as an aetiological factor in cirrhosis remains conjectural. In general, the post-hepatitic cirrhosis develops insidiously after a mild or unrecognised acute episode of hepatitis. General progress is slow. Early deaths are due to liver failure. Later, primary hepatocellular carcinoma assumes increasing importance. Needle biopsy of the liver is usually necessary to confirm the diagnosis of cirrhosis and to estimate the degree of activity. Sampling errors when such a small specimen of liver is obtained must be taken into account, when formulating a diagnosis and prognosis. Prednisolone therapy is usually given if the patient is symptomatic, biochemical tests are abnormal and the liver biopsy confirms active chronic hepatitis with or without cirrhosis. The evidence of benefit is not so strong as for other forms of active hepatitis and cirrhosis such as the lupoid type. The management of the cirrhosis is otherwise along orthodox lines.

Alpha1-antitrypsin deficiency (AATD), in addition to its association with chronic pulmonary disease, is reported with liver disease. Twenty per cent of Pi-type ZZ AATD infants present with a cholestatic type of neonatal hepatitis and develop a slowly progressive cirrhosis, and most die before adult life. Ten per cent of Pi-type ZZ adults develop cirrhosis. They have an increased frequency of primary liver carcinoma. In Z homozygotes and heterozygotes specific globules, due to accumulation of a type of alpha1-antitrypsin, are seen in liver cells. They are thought not to be hepatotoxic but to render the liver cell more susceptible to damage by an additional factor.

The authors report 4 cases of encapsulating peri-hepatitis, including an angiographic study. Selective arteriography of the coeliac trunk showed extremely sinuous intra-hepatic arteries in 3 of these cases, and obstruction of the portal vein, in one case. Catheterisation of the hepatic veins showed a pressure gradient between the obstructed hepatic vein and the free supra-hepatic pressure, showing a post-sinusoidal block. In 2 of the 4 cases, ascites was chylous. Lymphography carried out via lymphatics in the foot was negative in 3 cases where it was carried out. One case showed, on two successive laparoscopies, that micro-nodular cirrhosis was present before the development of encapsulating peri-hepatitis.
