In exsudate cells separated from serous body cavities of 29 tumour patients and 30 patients with inflammatory and congestive effusion in cardiac failure or liver cirrhosis respectively the activities of acid and alkaline phosphatase were determined. In addition to sudanophilia the cell content of glycogen and that of ribonucleinic acid were evaluated. By means of cytochemical findings it could be found that an increase of unspecific esterase, acid phosphatase and ribonucleic acid in atypical cells points to a malignous ethiology of the exudate.

Using cytochemical methods the authors studied the activity of certain lysosomal enzymes and cytochrome oxidase in peripheral blood leucoytes in 22 patients with Wilson's disease. The control group comprised 50 healthy blood donors. It was found that the activity of acid phosphatase in the lymphocytes of patients was higher than in controls, the mean indices being respectively 90.50 +/- 8.95 and 60.38 +/- 3.95. The activity of beta-glucuronidase was found to be lower in the lymphocytes of patients, the mean value was 25.10 +/- 8.59 in patients and 64.91 +/- 5.78 in controls. The activity of cytochrome oxidase was lower in the granulocytes of patients with Wilson's disease than in controls, the mean values being 54.5 +/- 12.14 and 156 +/- 15.41 respectively. The activity of acid phosphatase in granulocytes as well as that of non-specific esterase in lymphocytes was similar in both groups. Decreased antigen degradation in Wilson's disease may be due not only to liver cirrhosis but also to disturbances in the metabolism of white blood cells, including, among others, decreased activity of cytochrome oxidase. The rise of the activity of acid phosphatase and reduced activity of beta-glucuronidase indicate chronic antigenic stimulation of lymphoid system.

The plasma lecithin: cholesterol acyltransferase was determined in patients with various liver diseases and the relationship between this enzyme activity and the other liver function tests were studied including long term observations. Lecithin: cholesterol acyltransferase activity in fulminant hepatitis and liver cirrhosis showed a significant decrease in comparison with normal volunteers. Although the enzyme activity of hepatoma showed significant decrease, they were ascribed to the influence of concomitant liver cirrhosis. The enzyme activity showed insignificant changes in the acute and chronic hepatitis and alcoholic liver disease. Lecithin: cholesterol acyltransferase activity was correlated with the concentration of cholesterolester rather than with the ratio of esters to cholesterol. In addition, it was well correlated with pseudocholine esterase and serum albumin. The lecithin: cholesterol acyltransferase activity in the cases during follow-up period varied in good parallel with cholesterol-esters concentration and pseudocholine esterase in the cases with acute hepatitis; with serum albumin in the cases with liver cirrhosis. Furthermore, it varied inversely with SGPT in the cases with acute hepatitis. In a case with hepatoma, lecithin: cholesterol acyltransferase activity decreased more sharply than the cholesterolesters concentration and serum albumin immediately before death.

Extracellular water (EWC; 82-bromide), total body water (TBW; 3-THO), intracellular water (ICW = TBW-ECW), plasma volume (PV; 51-Cr), and total body potassium (TBK; 40-K) were studied in patients with cirrhosis of the liver (n = 12) and in controls (n = 12). ECW (39%), TBW (28%), ICW (19%), and PV (24%) increased, TBK (28%) however, decreased in cirrhosis. The results indicate that it is less the lean body mass, but rather the intracellular potassium concentration that is lowered (cirrhosis: 84 +/- 21 mmol/l ICW; controls: 115 +/- 23 mmol/l ICW). Decreased potassium per cell (mmol) and increased intracellular water are discussed as possible reasons for this. The correlation between TBK (%) and serum potassium (mmol/l) was found to be r = 0.56 (p less than 0.002). Correlations between the biochemical parameters gamma-globulins, cholin esterase, serum sodium and serum albumin (g/l PV) and characteristic fluid disturbances in cirrhosis are highly significant whereas albumin (g/kg bodyweight) was the same in both groups. We can support the 'overflow theory' of ascites formation.

The onset, culmination and involution of ovarian incretory function are reflected very sensitively in the hormonal colpocytological pattern. Disturbances of ovarian hormone production are associated with changes in lipid metabolism. The alpha-lipoprotein concentration falls and the beta-lipoprotein concentration rises. Postheparin esterase (PHE) and lipoprotein lipase (LPL) activity significantly influence the ovarian steroids. Oestrogens cause elevation of colpocytological oestrogenic indexes and lower PHE values. After the administration of testosterone in old age, the vaginal picture reacts by intermediary proliferation. PHE activity reacts by an increase. Like steroids, the enzymes PHE and LPL have a relationship to the liver cell. In cirrhosis the hormonal situation of the organism changes. The cytological picture in women after the menopause displays signs of proliferation, women in the childbearing period are hyperoestrogenic and PHE activity is low.

Plasma prekallikrein (kallikreinogen) and kallikrein inhibitor, assayed with the kaolin activable esterase method, have been evaluated in 20 patients with hepatic cirrhosis, in 12 cases with jaundice from acute viral hepatitis, and in 9 normal. A significant reduction of the plasma prekallikrein in cirrhosis has been found. A lowering of plasma prekallikrein has also been observed in viral hepatitis; in this condition, however, the modifications were less important than those obtained in cirrhosis. In three cases of hepatitis, the behaviour of the plasma prekallikrein and kallikrein inhibitor have been controlled during the period of the disease and compared with the behaviour of some conventional parameters, such as serum transaminases and bilirubin. An important increase of the prekallikrein level has been observed during the improvement of hepatitis. These data confirm the implication of the prekallikrein-kallikrein system in severe liver diseases, and indirectly points out the role of the liver in maintaining the physiological balance of the kallikrein system.

Using data from 17 patients with liver cirrhosis and 3 patients with fatty liver, we have compared the utility of 3 hepatic imaging agents in the evaluation of hepatic functional reserve. Evaluated here were 99mTc-galactosyl human serum albumin (GSA) which is a new ligand for hepatic binding protein, 99mTc-N-pyridoxyl-5-methyl tryptophan (PMT) of a hepatobiliary agent, and 99mTc-Sn colloid. In each patient, we performed these 3 imaging studies within a week and also examined hepatic function tests (indocyanine green test, hepaplastin test, choline-esterase, etc). In each imaging study, serial images and dynamic data were obtained after the injection of 99mTc-GSA (185 MBq/3 mg), 99mTc-PMT (185 MBq), or 99mTc-Sn colloid (185 MBq). Using the obtained dynamic data, we analyzed the liver kinetics of the 3 agents based on 1 compartment model with 3 parameters (hepatic clearance, hepatic excretion rate, non-specific volume of distribution). From fitting the liver and heart data to this model, three unknown parameters were determined. Patlak plot was also applied in order to estimate liver uptake rate. Both curve fitting and Patlak plot could determine appropriate parameters in every study. In 99mTc-GSA, a nonlinear 3 compartment model was also applied in order to estimate hepatic blood flow, liver receptor density, and affinity of receptor-GSA binding separately. Using the obtained parameters, we analyzed the correlations between the parameters and the results of hepatic function tests. In all of the parameters, those obtained from 99mTc-GSA imaging showed the most significant statistical correlation with the results of hepatic function tests. From the present results, 99mTc-GSA imaging was concluded to be the best for evaluation of hepatic functional reserve.

Previous studies have demonstrated that plasma tissue plasminogen activator (t-PA) level was elevated in patients with liver disease. In this study, t-PA antigen levels were investigated in patients with acute hepatitis (AH; N = 12), chronic hepatitis (CH; N = 8), compensated liver cirrhosis (CLC; N = 40), decompensated liver cirrhosis (DLC; N = 23) and hepatocellular carcinoma (HCC; N = 35). The increased t-PA levels (higher than 14 ng/ml) were found in 33% (4/12) of AH on the early hospital days, 25% (2/8) of CH, 45% (18/40) of CLC and 91% (21/23) of DLC, and 60% (21/35) of Hcc cases. In patient with LC, the correlations between t-PA levels and serum total bilirubin (T.Bill) and hepatic synthetic functions were investigated. The results were that the t-PA levels correlated positively with T. Bil and negatively with liver synthetic functions such as albumin, protein C and choline-esterase, indicating that t-PA increased almost in proportion to the deterioration of hepatic function. Serial determination of t-PA in patients with HCC treated by transcatheter arterial embolization (TAE) revealed that TAE failed to normalize the t-PA levels. In one case of HCC complicated with disseminated intravascular coagulation (DIC), t-PA showed a marked increase at acute phase of DIC and subsequent decrease after the successful treatment for DIC by gabexate mesilate (FOY) infusion. These results suggest that increased t-PA in liver disease is due mainly to deterioration of hepatic function, and that secondary fibrinolytic state, such as DIC, is also a contributing factor.

Although the liver is one of the four organs most often involved in generalized mastocytosis (GM), little is known about macroscopic and microscopic liver findings in this rare disease. This study included 182 patients with GM (confirmed in most by bone marrow histologic study), comprising 52 cases of our own and 130 reported in the literature. Hepatomegaly was found in 131 (72%) of the 182 patients, cirrhosis in seven (4%), and periportal fibrosis in 25 (14%). Mast cell (MC) infiltration of the liver was confirmed histologically in 77 (42%). Liver specimens were available for further histologic investigation in 11 of our own cases of GM. Nine of these contained MC aggregates. Mast cells were found predominantly in the portal tracts but numerous MC also were loosely scattered throughout the sinusoids. Diagnostic confusion of GM with reactive lesions of the liver is unlikely to occur since MC, according to our own observations and the available literature, are found only in very low numbers in normal liver tissue, where they occur mainly in the portal tracts. Reliable identification of MC does, however, require special stains, like Giemsa, toluidine blue, or naphthol AS-D chloroacetate esterase.

The profile of urinary salicylate metabolites was determined after the oral administration of acetylsalicylic acid (ASA) to CCl4-cirrhotic rats, CCl4-cirrhotic rats treated with colchicine for 1 month, and control groups. The following enzymatic activities were determined: liver and plasma ASA-esterase, liver UDP-glucuronyltransferase, and liver aniline hydroxylase. The time-course of plasma concentration of salicylates in similar groups was followed after the intraperitoneal administration of salicylic acid (SA) or gentisic acid (GA). The cirrhotic animals showed a lack of urinary glucuronates and an increase in urinary gentisic and salicylic acids. The activities of plasma and liver ASA-esterases were increased significantly in cirrhosis, whereas aniline hydroxylase was reduced and UDP-glucuronyltransferase remained unchanged. The plasma half-lives of salicylates were reduced in the cirrhotic animals regardless of the administered parent compound. Colchicine treatment reversed almost completely the alterations. The heterogeneity of liver metabolic dysfunctions present in chronic liver disease was demonstrated. It is emphasized that the pharmacokinetic alterations produced by liver damage are the result of a complex set of factors involving changes in the hepatic circulation, protein binding, and the existence of other routes of elimination.
