Serum gamma-glutamyl transpeptidase (gamma-GT) level was estimated in 132 patients with different liver diseases (chronic persistent and chronic active hepatitis, postnecrotic cirrhosis, chronic alcholic hepatitis and alcoholic cirrhosis, cholestasis syndrome, fatty liver, Gilbert disease) and malignancies with and without liver involvement. The gamma-GT levels were compared with the values for serum bilirubin, transaminases (GOT, GPT) and alkaline phosphatase in the same patients. gamma-GT values were normal in chronic persistent hepatitis and increased in chronic active hepatitis. Very high activities were measured in chronic alcoholic cirrhosis in contrast to postnecrotic cirrhosis. gamma-GT proved to be more sensitive than alkaline phosphate as an index of cholestasis and liver involvement in malignancies. It is suggested that gamma-GT activity offers valuable aid in differential diagnostics of liver-diseases. gamma-GT being an inducible enzyme, its activity may be raised by enzyme inducing drugs also in subjects without liver disease.

Within the framework of a prospective study on the course and prognosis of ulcerative colitis and Crohn's disease begun in 1968, serial blind needle biopsies of the liver were carried out for the early establishment of liver involvement. In 201 needle biopsies taken in 114 patients with ulcerative colitis, normal findings were observed in 51, fatty infiltration in 24, and accompanying inflammation in 23, fatty infiltration together with a mesenchymal reaction in 8, fatty liver in 6 and sclerosing cholangitis and granulomatous hepatitis in 1 patient each. Of 69 needle biopsies taken in 45 patients with Crohn's disease we established normal findings in 13, an insignificant accompanying inflammation in 19, fatty infiltration in 5, granulomatous hepatitis in 3, fatty liver in 2, fatty liver together with a mesenchymal reaction in 2 and serum hepatitis in 1. Laboratory tests (alkaline phosphatase, SGOT, SGPT, BSP excretion) are not particularly suitable as screening tests. The diagnostic yield of serial blind needle biopsies of the liver is low and, despite the low-risk nature of the method, often dispensable. Laparoscopy, or at least blind needle biopsy of the liver, should be retained for the further clarification of serious deviations of laboratory values from the normal range, or of suspicious palpation findings.

The effect of carbon-tetrachloride poisoning and the protection caused by AMP were studied. A single dose of CCl4 has resulted in a rapid development of a fatty liver, a considerable increase in serum enzymes, glutamic oxalacetic and pyruvic transaminases as well as serum-alkaline phosphatase. Total serum protein showed a tendency to decrease accompanied by a decrease in A/G ratio. Administration of adenosine-5-monophosphate prevented the increase in serum-alkaline phosphatase and increased the A/G ratio. There was, however, a slight but significant decrease in serum GOT and GPT within the 24-hrs. period of study, but it remained still higher than that of the control. AMP lowered liver fat without complete protection against the development of fatty liver.

Difficulties arise in the interpretation of liver tests in the pregnant subject, since some values increase (alkaline phosphatase) whilst others remain unchanged (transaminases) or fall during pregnancy. The diagnosis and management of some causes of jaundice in pregnancy, such as viral hepatitis, gall stones, benign intrahepatic cholestasis and acute fatty liver of pregnancy are discussed. Little is known about the commonest symptoms of pregnancy (nausea, vomiting and constipation) other than that they might be due to hormonally induced alteration of sphincter tone. However, pre-existing bowel disease has a greater effect on pregnancy. Fertility is reduced in poor nutritional states (e.g. coeliac and Crohn's diseases) and an increased occurrence of spontaneous abortion has been noted. For inflammatory bowel diseases, the time of onset is important in determining the outcome of pregnancy. Relapse in the disease is commonest in the first trimester and in the puerperium. Treatment of these conditions is essentially as in the non-pregnant subject. The controversial subject of sulphasalazine and steroid usage in pregnancy is discussed.

Liver function tests were performed in severe and mild diabetic rats and under the influence of ATP. In mild diabetics the serum cholesterol was significantly increased, while in severe diabetes the serum cholesterol was significantly lower than in mild diabetes. The decreased serum cholesterol in severe diabetes may be an indication for the development of fatty liver. The serum alkaline phosphatase and serum bilirubin were significantly increased in both the severe and mild diabetic states, while the thymol turbidity test was insignificantly changed in both states of diabetes. Serum albumin was significantly decreased in 10 days mild diabetes, while it was insignificantly changed in 48 hrs severe diabetic animals. The effect of ATP was investigated in mild diabetes. ATP resulted in a significant increase in serum albumin and a decrease in total globulins with the resultant increase in A/G ratio. The serum alkaline phosphatase exhibited a significant reduction under the influence of ATP. The elevated cholesterol of mild diabetic rats remained significantly elevated and was not reduced by ATP, though the fat content of the liver showed a significant reduction. This may be due to more rapid mobilisation of fat from the liver under the influence of ATP. ATP showed no significant effect on serum bilirubin and thymol turbidity test. the histopathological examination of the liver revealed that administration of ATP to alloxan diabetic rats had a beneficial effect. It resulted in disappearrance of the fat globules from the liver cells.

Changes of alkaline phosphatase activity in the process of healing liver injuries of rats on which partial hepatectomy was performed were the subject of our researches. Reaction on alkaline phosphatase was performed on cryostat sections according to the method of Gomori-Takamatsu. It has been found that granulated precipitate of cobalt sulphide was localized in the cytoplasm of granulocytes, macrophages and fibroblasts. A diffusive reaction comprized clusters of newly created collagen fibres. In early stages in the centres of necrosis, the activity of alkaline phosphatase increased, in later periods a lack of the activity was observed. Steatosis of liver tissue does not correlate with the intensity of the reaction. Lack of alkaline phosphatase activity is characteristic for old cicatrices. The authors discuss the effects of the histogenetical process during healing of liver injury on the results of the histoenzymatic reactions. The authors suggest that alkaline phosphatase is involved in the mechanism of re-building collagen fibres. It is stressed in the conclusion that the localization and intensity of alkaline phosphatase in the area of healing liver lesions are variable depending on the period of healing wound of the liver and the influence of other complications.

The most serious adverse effect of standard intestinal bypass for obesity is the high incidence of hepatic dysfunction and death from hepatic failure. We therefore examined the long-term effects of a modified form of jejunoileal bypass (in which a greater continuous length of ileum is retained), on liver function in 120 patients. Substantial weight loss (119-0+/-SD 23-3 kg to 82-3+/-18-8 kg) occurred during the first nine months after surgery, accompanied by a significant rise in serum concentrations of bilirubin, alanine transferase, and alkaline phosphatase, and a significant reduction in albumin concentrations. Biochemical changes were unrelated to weight loss or halothane anaesthesia. After weight stabilisation liver function reverted to normal, and four years after bypass sulphobromophthalein retention and hepatic histology did not differ from those in obese controls. There were two postoperative deaths. Three other patients died during the period of rapid weight loss with severe hepatic steatosis. While transient mild impairment of liver function is common after modified jejunoileal bypass, clinically significant hepatic dysfunction is a rare and unexplained early complication.

In an attempt to clinico-pathologically examine asymptomatic HBs AG carriers, follow-up studies were made on 57 HBAg-positive blood donors with the S-GPT within normal range and the following conclusions were arrived at: 1) The results of liver function tests made in the present studies revealed the following rates of abnormalities: the S-GPT was abnormal in 14.5% of the subjects, the S-GOT was abnormal in 9%, the serum total bilirubins were abnormal in 12.2%, the serum alkaline phosphatase level was abnormal in 24.5%, the TTT was abnormal in 4.4%, the ZTT was abnormal in 2.2%, the gamma-globulin was abnormal in 21.2%, and the ICG retention was abnormal in 25.6%. It was thus necessary to make a follow-up study of the results of liver function test. 2) Anti-HBs was negative in all subjects, the rate of lymphocytic blastogenesis in the peripheral blood (tested by the addition of PHA) was low in 7 (36.8%) of 19 patients, and the MIF test by the addition of the purified HBs Ag revealed that 17 subjects, excluding one subject with a histologic picture of acute hepatitis, were not susceptible to HBs Ag. It was, therefore, surmised that immunological insufficiency would be involved in the development of asymptomatic carriers. 3) Histologic examinations, made on 20 subjects, revealed A.V.H. in one subject, N.S.R.H. in seven, N.S.R. in ten and fatty liver in two, and further revealed mild, diffuse inflammations in 8 subjects in the first two group (40% in total). Further, pleomorphism was noted in the hepatocytes of 8 (40%) of these 20 subjects, and a study is under way of the significance of the pleomorphism.

Increased concentrations of neopterin have been found in conditions causing a stimulation of cellular immunity, including various malignancies. In liver diseases, serum or urinary neopterin levels have been studied in acute viral hepatitis, chronic hepatitis, fatty liver and liver cirrhosis. In the present study neopterin serum levels have been measured in 16 patients with hepatocellular carcinoma (HCC), in 32 patients with liver cirrhosis, and in 28 healthy subjects as controls. Mean values of serum neopterin were significantly increased (p < 0.01) in patients with HCC (15.89 +/- 6.34 nmol/l) when compared with those of normal subjects (4.74 +/- 2.13 nmol/l), but no difference was observed between patients with HCC (associated or not with liver cirrhosis) and patients with liver cirrhosis. Neopterin concentrations are not affected by liver cirrhosis aetiology, nor by its clinical severity, and are not correlated to the values of serum alpha-fetoprotein, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl-transferase, and gamma-globulin. The results show that there is a consistent overlap of values in patients with HCC and liver cirrhosis; macrophage activation seems to be a feature of chronic liver diseases, irrespective of HCC development.

Serum level of osteocalcin (OC) is believed to be a specific biochemical parameter of bone formation. Decreased serum OC has been reported in alcohol-intoxicated subjects, in patients with primary biliary cirrhosis and in patients with chronic alcoholic liver disease. The question was, whether lower OC level could be detected in patients with nonalcoholic and non-cholestatic chronic liver disease. The serum OC was measured by RIA developed in our laboratory. Results were compared to age and sex matched controls. Decreased OC level was found in 35 out of 47 (74%) patients with non-alcoholic and non-cholestatic liver disease as chronic persistent hepatitis, chronic active hepatitis, fatty liver and cirrhosis, in 21 out of 26 (80%) patients with alcoholic liver disease and in 8 out of 15 (53%) primary biliary cirrhosis. None of the patients had elevated value. There was no correlation between the decreased OC level and the duration or severity of the liver disease and the laboratory parameters as bilirubin, AST, ALT, alkaline phosphatase, albumin, prothrombin, and serum 25-OH-D3 vitamin level. Decreased OC was found also in the patients without cirrhosis. The possible causes are discussed. Relying upon these findings it is supposed that chronic liver disease by itself can influence the osteoblast activity also by some unknown mechanism.
