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.

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.

Lysosome are subcellular particles in which several acid hydrolases of various specificities are localized. The role of lysosome in cellular physiology and pathology has drawn considerable recent attention by several groups of investigators. The purpose of this study was to investigate the activities of lysosomal enzymes--acid phosphatase, beta-glucuronidase, N-acetyl-beta-glucosaminidase--in hepatic disorders. 1) The serum levels of beta-glucuronidase and N-acetyl-beta-glucosaminidase were significantly elevated in patients with diseases of the hepatobiliary system. 2) N-acetyl-beta-glucosaminidase activity in urine specimens from patients with diseases of the hepatobiliary system was found to be significantly higher than in urine specimens from normal adults. 3) Male albino rats of 150 approximately 200 g body weight were used. CCl4 was injected intraperitoneally (dose 0.1 ml of CCl4 per 100 g body weight twice a week for eight weeks). The free activities of lysosomal enzyme were increased and high free/total activity ratios were found in the liver lysosomal fraction of CCl4 intoxicated rats. The results of these experiment indicated that the membranes of lysosome were more permeable to their enzymes, and the release of these enzymes were found in the experimental fatty liver by CCl4. 4) Corticosteroids and chloroquine stabilized rat liver lysosome in vitro from the labilizing influence of incubation at 37 degrees C. 5) The administration of chloroquine to CCl4 intoxicated rats did not cause any well-expressed stabilization of lysosomes. 6) When alpha-Tocopherol was administrated to CCl4 intoxicated rats, the decrease of bound activity and increase of free activity in lysosomal fraction, and increase of acid hydrolases, GOT and GPT in serum were inhibited.

A study of the hepatic effects of Gravistat on 240 women is presented. 200 of the women had previously used either Ovosiston or Non-Ovlon continually for an average of 5.6 years, while the remaining 40 had used no hormonal contraceptives for the preceeding 3 months. After 3 weeks of Gravistat use, GOT, GPT, LP-X, and cholesterol levels were taken. 1/4 of the women in both groups showed pathological serum transaminase levels, and the cholesterol levels in both groups were within normal levels. 10 of the women who had previously used hormonal contraceptives, and none from the other group, showed a positive LP-X. A hepatological examination, including a liver biopsy, was performed on 30 of the women with pathological transaminase levels and/or positive LP-X. Pathological conditions (toxic hepatosis, infectious hepatitis, fatty liver) were found in 11 of those cases, while the rest showed metabolic activation. Intrahepatic cholestasis does not seem to be the major factor in the liver damage.

In order to examine a role of lysosomes in the pathogenesis of fatty livers, analysis was made on possible etiologic factors, clinical signs and symptoms as well as laboratory data of routine liver function tests in 32 subjects with fatty livers. Of 18 cases, enzyme activities of serum acid phosphatase (Acp), beta-glucuronidase (betaG) and n-acetyl-beta-glucosaminidase (nbetaG) were measured and compared with those obtained in 20 normal subjects. Subjective symptoms were observed in 75% of the cases examined, liver swelling in 56%, positive GOT, GPT and BSP retention were in 59, 75 and 68%, respectively. The activity of serum lysosomal enzymes such as Acp, betaG and nbetaG were significantly increased and their incidence was 28, 89 and 78%, respectively. In animal experiments, activities of these enzymes in both serum and liver homogenate were examined in rats with choline-deficient, ethionine-treated, and alcoholic fatty livers. Results obtained were as follows: 1) Lysosomal enzyme activity in sera and livers of choline-deficient rats showed a significant decrease in lysosome-rich fraction and a significant increase in supernatant fraction and sera. 2) The enzyme activity in ethionine-treated rats decreased significantly in lysosome-rich fraction and tended to increase in supernatant fraction. The activity of betaG in sera increased markedly. 3) In rats given ethanol for 4 weeks, the enzyme activity of sera and liver homogenates significantly increased in lysosome-rich fraction. These results indicate that the analysis of serum lysosomal enzyme activity, in the light of clinical features and laboratory data of routine liver function tests, is useful for the diagnosis of the fatty liver. A discussion is given of a possible mode of variation of lysosomal enzymes in rats with fatty livers.

A series of clinical-chemical tests was conducted in 68 schizophrenic out-patients under long-term neuroleptic medication, with particular consideration of the hepatic metabolism, i.e.: Erythrocyte sedimentation rate, alpha 1-glycoprotein, ceruloplasmin, fibrinogen, GPT, GOT, gamma-GT, total protein and serum-protein-electrophoresis. Furthermore, the glucose tolerance tests was carried out. In 44% of the patients an increased erythrocyte sedimentation rate and positive correlations with increased fibrinogen values were found. Increased gamma-GT-values were proven in 33% of the patients; they correlated positively with the increased GPT-and/or GOT-values as well as with pathological glucose tolerance values. Overweight of more than 10 kilos was found in 46% of the patients. A significant correlation between overweight and pathological glucose tolerance values existed. The results were interpreted as consequence of a light fatty liver.

Effects of choline fortification and various dietary protein levels on liver lipid content in pyridoxine-deficient rats were studied. Choline fortification did not prevent the accumulation of liver lipids in pyridoxine-deficient rats. Considerable accumulation of liver lipids was observed in the 70% casein pyridoxine-deprived group. Reducing the protein level in the diet decreased the extent of lipid accumulation. A highly negative correlation was found between liver lipid content and liver GPT activity, indicating that the fatty infiltration of the liver may be intimately related to the pyridoxine deficiency state. The time course of fatty liver induction upon feeding of a 70% casein pyridoxine-deficient diet was also studied. The liver lipid content increased gradually and reached the highest value by the third week with a concomitant decrease in food intake. Effect of change of dietary compositions on fatty liver caused by 70% casein pyridoxine-free diet was examined. Feeding of a 70% casein pyridoxine-supplemented diet or a 20% casein pyridoxine-free diet caused decreases in the liver lipids.

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.

To develop the prophylactics and the curatives for atherosclerosis, thyroxine derivative, CG-635, was assayed for its physiological activities in experimental atherosclerosis in rabbits fed with cholesterol. It was found that CG-635 possessed serum TC/TP value lowering activity (total cholesterol/total phospholipid) in normal and cholesterol fed rabbits for 3 weeks, and prevented the elevation of the value of cholesterol fed rabbits by daily injection for 7 weeks. CG-635 also depressed the hyperlipemia induced by cholesterol feeding, and its inhibitory effect was shown to be more marked on the increase of cholesterol than triglyceride, phospholipid and free fatty acid in serum. CG-635 did not, however, influence GOT, GPT and G-6-Pase activities in serum with increased cholesterol intake. From the histological findings it was proved that this compound prevented to a high degree the occurrence of atherosclerosis and fatty liver of cholesterol fed rabbits. Furthermore, it was recognized that thyroid hormone and the thyroid simulating hormone-like activities of CG-635 were much weaker than thyroxine, except for the action in the lipid metabolism.

On the basis of examinations of altogether 197 patients the results of the changes of GOT and GPT were compared with the old and new colour tests of the AWD Dresden in normal histology, virus hepatitis, fatty liver, liver cirrhosis and posthepatic occlusion. Though the new colour test reveals a higher sensitivity, the differential diagnosis between selected liver diseases, especially virus hepatitis and posthepatic occlusion syndrome have become more difficult. The cause for this is the less significant separability between the individual regions of reference.
