The influence of general anaesthesia for operations devoid of substantial tissue traumas on the postoperative pattern of hepatic enzymes was studied in 40 patients undergoing ophthalmologic surgery. 20 had neurolept analgesia, 20 had halothane anaesthesia. The duration of anaesthesia, age of the patients and their previous history corresponded fairly closely to those of a group of patients who had gynaecological operations and were the subject of a previous study. In contrast to the latter group total protein, cholinesterase, GOT, GPT, LDH, GLDH, AP, LAP and gamma-GT remained normal up to 12 days after the operation. The exception were changes in the total bilirubin levels which were similar to those observed in the gynaecological cases. Possible causes are discussed.

Of 146 patients with lymphogranulomatosis biochemical parameters were tested for their diagnostic valency concerning the recognition of a liver infiltration. In patients with histologically proved affection of the liver the AP, GGTP, AAP, LAP and LDH show a significant increase in comparison to the enzyme values of the patients without any hepatic manifestation. In an increased result of 4 enzyme values with a probability of 85% muste be reckoned with a participation of the liver. The enzyme SGOT, SGPT, GDH, LDH-isoenzymes, choline esterase, beta-GC, the De Ritis quotient and the quotient (Formula: see text), on the other hand, do not give any additional differential-diagnostic information.

In the present paper is reported on the behavior of different serochemical parameters in heterologous perfusion of the liver of pigs. The perfusion of the animal livers was carried out with preserved human blood in 11 recirculation experiments (closed machine circulations). In addition to this an empty circulation with human blood without attachment to an animal liver was carried out, whereby otherwise the arrangement of the experiment was the same, in order to take into consideration the effects of the blood traumatisation in the interpretation of the results. The enzymes GOT and LAP proved as sensible indicators of the lesion of the liver cells occurring in the perfusion of the liver of the pigs. The behavior of the mitochondrial GDH as well as of the lysosomal enzymes SP and BETA-GC which scarcely increased during the recirculations in the perfusate blood, however, allows the conclusion that there did not appear a severe lesion of the liver cells (necrobiosis) during several hours of perfusion. A cholestasis did not develop during the perfusions, when one takes as basis the behavior of the enzymes AP, GGTP and AAP indicating cholestasis. Compared with GOT the enzyme GPT showed by far less elevations in the perfusate blood so that with increasing duration of the perfusion the De-Ritis-quotient significantly increased. Increased LDH-activities above all revealed the increasing during perfusion haemolysis and less reliably a lesion of the liver of the pig. The increase of ADA in the perfusate blood proved as nearly exclusively conditioned by haemolysis. Total protein, albumins, immunoglobulins, cholinesterase and thymol turbidity test remained unchanged in the course of the perfusions.

A description is given of an outbreak of equine infectious anaemia (E.I.A.) in Campania [at Naples and Aversa (Caserta)]; it was diagnosed by clinical, pathological and serological examinations (Coggins test). Using the serum of 45 horses with E.I.A. and 11 healthy horses (controls), numerous investigations were carried out on: enzymes, intrinsic coagulation factors, lipids and other substances. The results obtained were very interesting and show that in this disease there are significant increases in many enzymes (LDH, LAP, gamma-GT, CPK, PK and ALD) and copper. Insignificant increases were found in other enzymes (SDH, GLDH, MDH, ICDH, AIP, lysozyme, cholinesterase, GOT and GPT) and also intrinsic coagulation factors, lipid substances (total cholesterol, esterified cholesterol, triglycerides) and glucose. LDH-1-isoenzyme remains unchanged, whilst AcP decreases slightly.

Nonvaccinated pigs were infected with a pathogenic virus of swine fever in order to follow up the changes with some enzymes in their blood serum. It was found that there is a dependable rise in the values of the blood serum GOT (2.6.1. 1.) - From about 38 to approximately 108 mU per cu. cm; GPT (2. 6; 1.2.;-From about 12 up to 66 mU/cu. cm; LAP (3. 4. 1. 1)-from about 13 to 27 mU/cu. cm; and ALD (4. 1; 2. 7.) - from about 6 up to 19 mU/cu. cm. These changes were noticed as early as the 48th hour of infection, prior to the manifestation of the clinical symptoms of swine fever. They remained stable up to the end of the infection process. The activity of LDH (1. 1. 2. 7.) and amylase (3. 2. 1.1 .) was said to rise (not dependable statistically), and that of cholinesterase (3. 1 1. 8) - to drop gradually with the development of the infection process. The two phosphomonoesterases (3. 1. 3. 1 and 3. 1. 3. 2.) showed no essential changes. The changes taking place in the activity of these enzymes did not depend on the extent of the hemorrhagic diathesis characteristic of swine fever. So, this test, which has been unknown so far, is referred to as a characteristic paraclinical symptom of swine fever.

Clinical usefulness of mean transit time (MTT) through the liver was evaluated by deconvolution analysis using 99mTc-EHIDA hepatobiliary scintigraphy in 82 patients with various hepatobiliary diseases and 18 normal controls. Initial transfer factor was also obtained according to the method of Rutland. Results obtained were as follows. 1) Effect of the age on MTT was not observed in normal controls. 2) MTT in left lobe of normal controls was significantly prolonged compared with that of right lobe (P less than 0.01). This kind of difference was not observed in patients with liver cirrhosis. 3) MTT in patients with obstructive jaundice, chronic liver diseases, liver cirrhosis at decompensative state and primary biliary cirrhosis was significantly prolonged compared with that in normal controls (P less than 0.01). 4) MTT in patients with liver cirrhosis at compensative state showed normal values, although blood clearance rate in those patients was significantly decreased (P less than 0.05). 5) Positive correlation was observed between MTT and values of T-Bil, ALP, LAP, and gamma-GTP. Negative correlation was observed between MTT and value of cholinesterase. 6) Initial transfer factor correlated with blood clearance rate. (r = 0.76, P less than 0.01). 7) Initial transfer factor in left lobe of normal controls was significantly decreased compared with that of right lobe (P less than 0.01). This kind of difference was not observed in patients with liver cirrhosis. 8) Initial transfer factor in patients with liver cirrhosis in both compensative and decompensative states and PBC was significantly decreased compared with that in normal controls. Estimation of MTT and initial transfer factor could be a useful parameters to assess transfer function of the liver.

Sex, age and 21 routine liver function assays were analyzed by stepwise selection and the best-of-all-possible-combinations method to identify a small group of assays valuable in establishing which liver cirrhosis (LC) patients have a high risk of hepatocellular carcinoma (HCC), when alpha-fetoprotein (AFP) is not elevated. Data was obtained from 115 HCC and 122 LC patients on admission. Tumor size correlated with AFP (0.73), alkaline phosphatase (ALP, 0.47), leucine aminopeptidase (LAP, 0.42), lactic dehydrogenase (LDH, 0.42), and the glutamic oxaloacetic transaminase (GOT)/glutamic pyruvic transaminase (GPT) ratio (GOT/GPT, 0.41). The mean of the correct diagnosis rates (CDR) of HCC and LC utilizing AFP as the sole parameter (89%) was markedly higher than those of the other parameters. The best-of-all-possible-combinations method presented a more powerful combination than stepwise selection. The best combination of 7 parameters (LAP, GOT/GPT, choline esterase, one-hour erythrocyte sedimentation rate, age, albumin/globulin ratio, and total bilirubin) presented a mean CDR of 80%, HCC CDR of 77%, and false positive rate of 18%. LC patients statistically diagnosed as having HCC by these 7 parameters are proposed as high risk patients. Fourteen (78%) of 18 HCC patients who were AFP-negative were statistically diagnosed. This analysis can be applied to LC patients to distinguish those that should be followed closely by imaging diagnostic techniques.

A change in erythrocyte osmotic fragility was observed on various liver diseases by means of the coil planet centrifuge (CPC) system, and the relationship between changes in it and in serum lipids was studied. According to the CPC classification of hemolytic patterns of L, M, T and R, the frequency of appearance of T and R increased in liver cirrhosis and primary hepatoma. Hemolytic start and end points both changed considerably in primary hepatoma, acute hepatitis and liver cirrhosis. Change of hemolytic end point which shifted to the hypotonic side is more prominent than that of hemolytic start point. The hemolytic end point showed an inverse correlation to serum alkaline phosphatase and LAP, and correlation to pseudocholinesterase and albumin. Among the relations of red cell fragility and lipids of the lipoprotein fractions, free cholesterol and the ratio of free cholesterol to phospholipid in high density lipoprotein were both in remarkable inverse correlation to the hemolytic end point. Free cholesterol in high density lipoprotein was concluded one of the most important determinants of erythrocyte osmotic fragility.

Clinical symptoms and abnormality of laboratory examinations in 62 patients with proven pancreatic carcinoma were studied. The following indications for detailed examination of the pancreas have been evolved: (1) vague abdominal symptoms, (2) jaundice, (3) abnormalities of laporatory examinations including serum LAP, ALP, amylase and cholinesterase level, and abnormal GTT. In the jaundiced patient the initial examination is US followed by PTCD to relieve the jaundice, and then angiography to assess resectability of the tumor. In the non-jaundiced patient US is used as a screening procedure. Should this be abnormal a lesion may be confirmed by CT. If not ERCP is indicated when there is some distinct reason to suspect pancreatic disease. If ERCP reveals abnormality then angiography is performed to determine whether the lesion is benign or malignant, and if malignant it is resectable or not. In the period of 1968 and 1981, 112 proven pancreatic carcinomas were studied. Overall resectability was 26%. Thirty tumors were less than 3 cm and the smallest lesion measured 1.2 cm.
