The methodology of a large prospective study on the influence of repeated anaesthetics on liver function is reported and the problems involved are discussed. The most suitable patients were those presenting for endoscopic examination of the bladder and urethra, for urethral dilatation and for cervical implantation of radium. Blood samples were taken immediately before induction of anaesthesia and on days 3-4 and 13-15 after operation, when a clinical assessment of the patient was also carried out. The concentrations of six enzymes (lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, serum cholinesterase and gamma glutamyl transpeptidase) werechosen specifically as indices of liver function. The eosinophil count was measured to reflect any hypersensitivity reaction. The non-Gaussian distribution of these necessitated using appropriate non-parametric tests together with parametric tests on logarithmic transformed data. In addition a quantal method was used to measure the frequency of patients showing an "abnormal" increase in enzyme concentrations.

The biological effects of a new synthetic progestagen, Org 2969 (13-ethyl-11-methylene-18,19-dinor-17 alpha-pregn-4-en-20-yn-17-ol) were studied in healthy normally menstruating women. Two of them were given 0.125 mg, five 0.060 mg and two 0.030 mg of Org 2969 daily on days 1-20 during one menstrual cycle. Serum levels of follicle stimulating hormone, luteinizing hormone, progesterone and oestradiol were analyzed on days 8-23 in order to evaluate the function of the hypophyseal-ovarian axis. The serum concentrations of aspartate amino transferase, alanine amino transferase, alkaline phosphatase, gamma glutamyl transpeptidase and bilirubin were determined to evaluate possible side effects on live function on days 8, 15 and 23. Serum cortisol was measured on days 8 and 23. The basal body temperature was recorded daily during the whole cycle, and endometrium biopsies were taken on days 21 or 22 of the cycle. All samples were taken similaryl during the treatment cycle and the preceding control cycle. According to the hormone determinations, all the treatment cycles were anovulatory except in one woman receiving the lowest dose. The treatment led to decreased spinnbarkeit, arborization and sperum penetration in the cervical mucus. Liver function tests and serum cortisol remained unchanged during the treatment.

Ninety-nine Black females receiving radium therapy for carcinoma of the cervix uteri under either halothane (50 patients) or enflurane (49 patients) anaesthesia were studied. Thirty-six received a second and 13 a third exposure to halothane or enflurane. There were no significant changes from the control values in the serum concentrations of aspartate aminotransferase (s.g.o.t.), gamma glutamyl transpeptidase (gammaGT), lactic dehydrogenase (SLD), alkaline phosphatase (SAP) and proteins. Total serum bilirubin (TSB) decreased significantly during the first exposure to enflurane (P less than 0.01). This trend was reversed with subsequent anaesthetics in both the halothane and enflurane groups.

Lead markedly augments the lethality of endotoxin lipopolysaccharide (LPS) in rats. In this model of LPS toxicity, the liver is severely injured. Much of the tissue injury produced by LPS is thought to be mediated by the cytokine tumor necrosis factor (TNF). Tumor necrosis factor recently has been speculated to be a mediator of several models of liver injury such as that produced by galactosamine. To investigate the possible role of TNF in the lead-enhanced LPS toxicity model, we administered doses of lead acetate (15 mg/kg), LPS (100 micrograms/kg), or TNF (6.25 x 10(6) U/kg) that produced minimal changes in liver enzymes. However, when lead was administered simultaneously with either LPS or TNF, serum aspartate transaminase, alanine transaminase, alkaline phosphatase, glutamyl transpeptidase, and plasma triglyceride levels were markedly increased. Lead + LPS treatment increased both peak serum TNF concentrations and TNF "area under the curve" as compared with LPS alone. We conclude that lead not only enhances LPS lethality but also LPS liver injury. Furthermore, lead enhances TNF liver injury and increases LPS-stimulated serum TNF levels. These data suggest that the lead-enhanced LPS model offers a system for studying TNF-induced liver injury.

The liver enzymes, aspartate transaminase (AST), alanine transaminase (ALT), gamma glutamyl transpeptidase (GGT) and alkaline phosphatase (ALP), were measured in the blood of 25 fetuses with severe Rh alloimmunization at the time of their first, second and third intravascular transfusions and in 17 comparison fetuses. In the comparison group, GGT increased with advancing gestation (r = 0.7; P = 0.002), whereas ALP, AST and ALT did not correlate with gestational age. Rh hydropic fetuses (n = 8) had higher blood ALT levels than the comparison fetuses (P = 0.008) had significantly increased transaminases when compared with non hydropic fetuses (n = 17). In hydropic fetuses, AST correlated with the nucleated red cell count before transfusion (r = 0.94; P = less than 0.0001). Fetal transaminases were no longer increased in hydropic fetuses by the second (AST) or third (ALT) transfusion. In both hydropic and non hydropic fetuses, GGT increased by the second transfusion (median percentage change +85%, range -83% to +596%; P = 0.003). The rise in fetal GGT was transitory and correlated with the increase in fetal haematocrit at the first transfusion (r = 0.58; P = 0.006). This study reports liver dysfunction secondary to extramedullary erythropoiesis in Rh alloimmunization and implicates portal hypertension for the rise in fetal GGT with transfusion.

1. Analysis of biochemical parameters was carried out on material pooled from 10 baboons, adult male and female, of the Papio c. cinocephalus strain. 2. The values determined were for the common metabolites and enzymes utilized for specific studies in general metabolism (urea, glucose, cholesterol, phospholipids, bilirubin, uric acid, creatinine, alkaline phosphatase, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactic dehydrogenase, leucine amino peptidase, gamma glutamyl transpeptidase, total creatine kinase and amylase). Total protein and its fractions (ratio albumin/globulin, albumin, alpha 1-globulin and alpha 2-globulin) were also determined. 3. Results of these studies were compared with values for normal human adults. 4. The differences obtained between the respective ranges can be explained by the different physiology of the two species and, possibly, may also be caused by the use of human substrates in the enzyme assays. 5. Through the determination of normal values for the baboon, this study provides values for this species as an experimental animal in biomedical research.

Seven women, mean age 47.7 years, with primary biliary cirrhosis (6 patients in the II-III stage and I patient in IV stage of the disease) were treated in the course of 16 months with ursodeoxycholic acid (Ursofalk) 500 mg daily. At the end of the 3-d month of treatment the itching had passed in 3 of the patients and in the remaining 4 patients it had substantially decreased. In all patients the subjective complaints, dyspeptic syndrome, appetite and sleep improved. The serum concentrations of bilirubin, copper and cholesterol started to decrease and the serum activity of the enzymes alkaline phosphatase, ALAT and ASAT also decreased. In one patient the treatment was discontinued in the 6-th month because of allergic reaction. After 16 month treatment in the 6 patients who completed the treatment the itching passed and the working capacity improved. The serum concentrations of bilirubin, cholesterol, copper and IgG significantly fell (p less than 0.01), the serum activity of alkaline phosphatase, gamma glutamyl transpeptidase, ALAT and ASAT fell near the upper normal range. The hepatomegaly, splenomegaly, McLagan's flocculation test, serum concentration of IgM and the titer of the specific antimitochondrial antibodies (M2) did not change in spite of the treatment. The results show the ursodeoxycholic acid as a perspective therapeutic means for primary biliary cirrhosis which lowers or overcomes the syndrome of intrahepatic cholestasis and limits the activity of the cirrhotic process in the liver. Ursodeoxycholic acid is well tolerated.

Biochemical components usually evaluated in seminal plasma are lower than those in blood serum. In this study the concentration of different constituents in seminal plasma has been analyzed: creatinine, urea, glucose, uric acid, sodium, potassium, triglycerides, cholesterol, bilirubin, alkaline phosphatase, glutamic oxalacetic transaminase (SGOT), glutamic pyruvate transaminase (SGPT), cholinesterase, creatin phospho chinase (CPK), gamma glutamyl transpeptidase, lactic dehydrogenase (LDH), proteins, in comparison with the concentrations of the same constituents in blood. With the exception of uric acid, all the biochemical components in the seminal plasma were either significantly higher or lower than in blood serum, an index of the complexity of the mechanism regulating the presence and distribution of the single components in seminal plasma compared with blood serum. Isoelectro-focussing for proteins showed, in seminal plasma, a higher quantity of fragments and a different distribution of this in comparison with blood serum.

The clinical diagnostic utility of CA-50 (time-resolved fluoroimmunoassay) and Span-1 was compared with that of CA19-9 by measuring their levels in sera from patients with pancreatic cancer and other diseases. In pancreatic cancer CA-50, Span-1, and CA19-9 showed similar positive rates (84%, 82%, and 81%, respectively). With regard to the ability to distinguish pancreatic cancer from chronic pancreatitis, however, the specificity of CA-50 and Span-1 was higher than that of CA19-9 (85%, 85%, and 79%, respectively). Despite the similar positive rates of CA-50 and Span-1 in pancreatic cancer, the correlation between these two markers was low. Thus, used in combination, they compensated for each other in the diagnosis of pancreatic cancer. In chronic liver diseases, serum levels of both CA-50 and Span-1 were correlated with that of biliary tract enzymes, alkaline phosphatase, and r-glutamyl transpeptidase. And these two markers were more affected by the biliary system than CA19-9, resulting in the significantly higher positive rates. In these diseases immunohistochemical study showed that all three markers were localized in the epithelial cells of the bile duct, with CA-50 and Span-1 showing a similar tissue distribution.

In a group of 466 cholecystectomies with peroperative cholangiography the authors revealed sensitivity of the examination for cholangiolithiasis (255 before operation) in 95.3%, for diagnosis of all benign diseases of the bile ducts (288 operations) in 95.8%. They established six indication criterias for peroperative cholangiography during cholecystectomy: 1. jaundice or elevated serum bilirubin before operation, 2. pancreatitis or elevated amylase values in blood or urine before operation, 3. elevated alkaline phosphatase (ALP) or gamma-glutamyl transpeptidase (GMT) serum values before operation, 4. small (under 3 mm) or multiple (more than 10) gallstones, 5. a choledochus wider than 10 mm, 6 a cystic duct wider than 3 mm. As indication suffices positivity of one of the criteria. By introducing these indications it was possible to reduce peroperative cholangiography during cholecystectomies by cca 40% with a 0.1% risk of diagnostic errors in the diagnosis of benign diseases of the bile ducts.
