Serum activities of alanine-aminotransferase (ALAT, EC 2.6.1.2), aspartate-aminotransferase (ASAT, EC 2.6.1.1), lactate dehydrogenase (LDH, EC 1.1.1.27), and alkaline phosphatase (AP, EC 3.1.3.1) were increased significantly after a dose of 0.16 g/kg/b. w. (ip.) carbon tetrachloride (tetrachloromethane) in rats pretreated with 10% (v/v) ethanol for one and 10 weeks in comparison with water/carbon tetrachloride-treated animals. At the end of 30 and 52 weeks of ethanol consumption these levels were very slightly increased or not detectable. Ethanol treatment alone did not cause an increase in serum enzyme activities or histological liver damage, but caused a diminished intake of fluid and food and in some cases also a reduction of weight gain in the animal body. Significant decrease in body weight after carbon tetrachloride was more evident in rats pretreated with ethanol (1 week greater than 10 greater than or equal to 52 weeks) than in water drinking animals, the lethality caused by carbon tetrachloride was also higher after one and 10 weeks than after 30 to 52 weeks of ethanol pretreatment. The results indicate a decrease of carbon tetrachloride toxicity with increased duration of ethanol pretreatment. This phenomenon could be attributed to reduced sensibility to those alcohol effects which are responsible for increase of carbon tetrachloride toxicity.

Biochemical parameters sodium, potassium, lactate, alkaline phosphatase, ASAT, and ALAT were examined at the beginning of the operation, before, and 0, 2, 4, 6 hours after implantation of a small bowel autograft in an autologous model of intestinal transplantation in dogs. By the way of these early biochemical studies we have got information about metabolic situation during organ transplantation, efficiency of preservation and vitality of the graft. Using the given method safe preservation of small bowel can be guaranteed. Postoperatively only little changes of laboratory parameters occur.

300 consecutive cholecystectomies performed from 1984 through 1986 were studied retrospectively to answer the following questions: which are suitable preoperative indicators for selective operative cholangiography, and which is the failure rate to detect biliary concrements by selective cholangiography? Patients with a history of jaundice, suspected concrements from preoperative intravenous cholangiography or ultrasound examination, a common bile duct wider than 8 mm, and elevated serum levels of bilirubin, alkaline phosphatase, ALAT (GPT) or ASAT (GOT) all had significantly higher rates of biliary concrements. Of these indicators, preoperative radiologic studies, serum levels of ALAT (GPT) and serum levels of alkaline phosphatase showed the best sensitivity, specificity as well as positive and negative predictive value. If two criteria, preoperative radiology and serum levels of ALAT (GPT), had been used, intraoperative cholangiography would have been performed in 34% of the cases. 82% of all biliary concrements would have been detected; in 3% of all cholecystectomies, the diagnosis of concrements would have been missed. We conclude that prospective studies should be performed to better define necessity and benefit of routine operative cholangiography still widely performed today.

Sixty-one patients with acute necrotizing pancreatitis were studied for age, sex, ASAT, ALAT, alkaline phosphatase, bilirubin and amylase 48 hours after admission, these factors having recently been found to be significant in predicting this gallstone-associated disease. Age, ASAT, ALAT and alkaline phosphatase were found to be significant. However, 38 per cent of the patients with pancreatitis and gallstones remained unidentified with these criteria only. Thus, more intensive methods of investigation should be used whenever gallstone-associated pancreatitis is suspected. Increased hepatic chemistry could seldom be explained by the necrotizing form of pancreatitis if there was no biliary tract cause.

Alkaline phosphatase (ALP, EC 3.1.3.1), acid phosphatase (ACP, EC 3.1.3.2), aspartate aminotransferase (ASAT, EC 2.6.1.1) and alanine aminotransferase (ALAT, EC 2.6.1.2) were measured in the mucosal homogenates of the duodenum, jejunum and caecum of full-fed (control), starved and refed White Rock Cockerels. Starvation caused a significant (p less than or equal to 0.05) increase in the activity of ACP in all three segments of the intestine. Subsequent re-feeding brought the activity back to the control level. In contrast ALP activity fell in the duodenum during starvation and was partially restored by refeeding. In the jejunum and caecum the ALP activity decreased during starvation and was fully restored by re-feeding only in the caecum. ASAT activity increased (p less than or equal to 0.05) during the entire period of starvation in all three segments. Re-feeding failed to decrease the enzyme activity within 48 hours. Starvation caused a reduction (p less than or equal to 0.05) in the activity of ALAT and re-feeding did not increase the activity in the duodenum and jejunum. The caecum showed no change in the activity during fasting.

The study includes 108 patients with acute alcohol hepatitis, 45 patients with cholestasis and 124 healthy controls. In 14 patients (13%) cholestatic acute alcohol hepatitis was found. The patients with cholestatic acute alcohol hepatitis consumed considerably more alcohol than the other patients with acute alcohol hepatitis. The intensive jaundice led half of the patients with cholestatic acute alcohol hepatitis to the infectious diseases clinic and 32% of them to the surgical clinic. The course of the disease was heavy, with disturbed general condition, high temperature, pain in the right subcostal region but without itching. The patients showed higher levels of timol test, cholesterol, LDL-cholesterol, coefficient LDL/HDL-cholesterol, beta-lipoproteins, total lipids, gamma-GTP, ASAT and lower levels of leucocytes, bilirubin, SMC, alkaline phosphatase and LAP than the other patients with cholestasis. The patients with cholestatic acute alcohol hepatitis showed a higher level of total lipids and gamma-GTP than the other patients examined. The confirmation of the diagnosis implies the application of contemporary instrumental and invasive methods. The ultrasound examination is of special importance.

1. Alkaline phosphatase [EC 3.1.3.1], acid phosphatase [EC 3.1.3.2], aspartate aminotransferase [ASAT, EC 2.6.1.1] and alanine aminotransferase [ALAT, EC 2.6.1.2] were measured in mucosal homogenates of different segments of the alimentary tract of White Rock cockerels. 2. The activities of acid and alkaline phosphatases were higher in the duodenum, jejenum and caecum than the anterior segments of the alimentary tract. 3. The activity of aspartate aminotransferase was higher in the oesophagus and crop than in the caudal segments of the alimentary tract. Alanine aminotransferase activity did not show any specific pattern. 4. The increased phosphatase activities in the caudal alimentary tract indicates their involvement in the nutrient transport across the mucosa. Aminotransferases were probably involved in the synthesis of amino acids and proteins in the anterior alimentary tract.

The effects of a new synthetic steroid Org OD 14 on the haemostatic mechanism were investigated in 60 post-menopausal women, randomly allocated to 12 weeks of treatment with either 2.5 mg/day of Org OD 14 or a placebo in a double-blind, group-comparative study. Assessments were made 2 weeks before and just prior to the start of treatment, at weeks 6 and 12 during treatment, and 2 weeks after its cessation. No significant differences between the two groups were found with regard to prothrombin time, kaolin cephalin clotting time (KCCT), clotting factors VII, VIII and X, white blood count (WBC) or transaminases (ASAT, ALAT). The following statistically significant differences were seen in the Org OD 14 group: higher plasminogen, antithrombin III, haemoglobin, haematocrit and platelet count, and increased fibrinolytic activity on fibrin plates, as well as lower fibrinogen and alkaline phosphatase values. These findings indicate that Org OD 14 displays no adverse effects on coagulation, while changes in fibrinolysis seem to be beneficial for post-menopausal women.

The following recommendations are to be given for the basis diagnosis of hepatitis: --In the blood donation and blood transfusion institutions the control of the donors is performed by means of the combination ALAT and HBs-antigen (transmigration electrophoresis); depending on methods limits were established showing a high diagnostic specificity. Thus, no doubt, the diagnostic sensitivity is decreased, but the number of the examined persons with falsely positive findings probably diminishes. --For the diagnostics in the clinic the parameters ALAT, ASAT, bilirubin and the thymol turbidity test are at the disposal as criteria of the liver cell damage as well as AP (alkaline phosphatase), AAP and GGT as criteria of the cholostasis and the thymol turbidity test, serum protein including immunoglobulins as criteria of the mesenchymal reaction. The reference areas must be established method-specifically corresponding to the interrogation of the physician. --The isoenzymes of the ALD, the ASAT and the LDH represent an essential enrichment of the diagnostic and prognostic estimation of hepatitis. But at present it is not yet possible to determine these parameters in routine work. However, there gradual introduction into practice should be the aim.

Sixty-four patients over the age of 40 years, undergoing elective surgery of at least one hour's duration, were randomized to treatment with either a thromboembolic deterrent ( TED ) stocking (Kendall Co.) or subcutaneous low-dose heparin 5 000 IU every 12 hours. Serum levels of alanine aminotransferase (S-ALAT), aspartate aminotransferase (S-ASAT), gamma-glutamyl transpeptidase (S-gamma-GT) and alkaline phosphatase (S-ALP) were measured. S-ALAT increased significantly on the 5th and 10th postoperative day, from 27 +/- 2 (x +/- SE) to 40 +/- 4 (p less than 0.01) and 55 +/- 7 U/l (p less than 0.001), respectively, in the heparin group and was significantly higher in the heparin than in the TED group both on the 5th (p less than 0.01) and 10th (p less than 0.05) postoperative day. S-ASAT and S-gamma-GT increased significantly during heparin treatment, but did not differ significantly from the values of the TED group. No change in S-ALP was registered in either group. It is concluded that prophylactic treatment with low-dose heparin induces a significant increase in S-aminotransferase levels, especially in S-ALAT. The phenomenon has profound differential diagnostic implications in conditions such as pulmonary embolism and acute myocardial infarction.
