Under general anaesthesia the common bile duct was ligated in two sheep and two calves. Occlusion of the duct was permanent and was followed by portal fibrosis, proliferation of bile ducts and intrahepatic bile stasis. Mild hepatic cell damage was accompanied by the release of glutamate dehydrogenase, sorbitol dehydrogenase and arginase into serum. The release of gamma-glutamyl transpeptidase was slower but more continuous. One sheep and one calf developed peritonitis associated with the leakage of bile from a biopsy wound in the live. One of these animals and the other two on which biopsy was not performed became photosensitised on exposure to sunlight. The concentration of phylloerythrin was high in serum and urine. All animals became jaundiced and the increased concentration of bilirubin in serum and urine was mainly direct reacting, ie, conjugated with glucuronic acid.

The effects of different kinds of anesthesia on the function of live (evaluated on the basis of activity of enzymes -- aspartate aminotransferase, fructose-I-monophosphate aldelase and glutamate dehydrogenase) were studied in 63 infantile patients with Hodgkin's disease who underwent diagnostic laparotomy with splenectomy. It was found that during the first 6 days after surgery, the rate of activity of these enzymes shows a rise and reaches the upper limits in 77.8% of cases. Halothane anesthesia induced excessive enzymatic activity in 100%, while neuroleptanalgesia -- in 53.8% of cases. Repeated application of halothane produced a higher hepatotoxic effect as manifested by enhanced activity of glutamate dehydrogenase on days 1--2 after operation.

A placebo-controlled, randomized blind study was conducted in cats (n = 60) after fracture repair to compare the analgesic effects as well as the side-effects of carprofen, buprenorphine and levomethadone during a 5-day treatment. Cats with severe shock symptoms or increases in blood urea nitrogen (BUN) and creatinine were excluded from the study. The cats were randomly assigned to four groups (n= 15). In group 1, carprofen was administered upon extubation at an initial dose of 4 mg/kg body weight, followed by one-third of that dose three times daily on days 2 to 5. In group 2, buprenorphine was administered in a single dose of 0.01 mg/kg body weight upon extubation and subsequently every 8 h. Levomethadone (group 3) was applied according to the same scheme at a dosage of 0.3 mg/kg body weight each time. The placebo (group 4) was given at the same time intervals as the opioids. Examinations were carried out prior to anaesthesia, between 30 min and 8 h after extubation, and on the following 4 days, 1 h after administration of the analgesics or the placebo as well as 1 h before the next administration. Pain and sedation evaluation was carried out with a visual analogue system (VAS) and with the aid of a numerical estimation scale (NRS). Pain was also scored by measuring mechanical nociceptive threshold of traumatized tissue. Plasma glucose and cortisol concentration, heart rate, respiration rate, blood pressure and body temperature were measured. Furthermore, a complete blood count and clinical chemistry including BUN, creatinine, alanine aminotransferase (ALT), glutamate dehydrogenase (GLDH), arterial blood pressure (AP), total protein and electrolytes of the cats were checked on the day of admission as well as on the last day of this study (day 5). Defaecation and urination as well as wound healing were monitored. On the basis of the mechanical nociceptive threshold of the traumatized tissue, concentrations of plasma glucose and cortisol and pain assessment using NRS and VAS, carprofen was found to have better anti-nociceptive efficacy when compared with the two opioid analgesics, while the analgesic effect of levomethadone was similar to that of buprenorphine. However, the carprofen group also showed comparably high median NRS and VAS pain scores in addition to occasional broad deviations from the group mean on the first post-operative treatment day. Sedative effects were detected for buprenorphine and levomethadone; in addition, symptoms of central excitation were noted with levomethadone. There was no indication of any clinically relevant respiratory depressive or cardiovascular effects, nor of any undesired renal, gastrointestinal or hepatic effects of the analgesics applied. However, the somewhat insensitive examination methods did not permit sufficient evaluation of side-effects, particularly on the gastrointestinal tract and the kidneys. It was found that carprofen and buprenorphine were well-tolerated analgesics for a 5-day administration in the cat, whereas levomethadone caused central excitation in some cases in the dosage scheme used here. However, it was apparent that none of the tested analgesics induced sufficient analgesia in the post-operative phase. For this reason, suitable methods must be found to improve analgesia, particularly in the immediate post-operative phase.

In this study, we aimed to investigate the effects of vitamin U (Vit U) on valproic acid (VPA)-induced liver damage. Female Sprague Dawley rats were randomly divided into four groups. Group I was intact control animals. Group II was control rats given Vit U (50 mg/kg/day) for fifteen days. Group III was given only VPA (500 mg/kg/day) for fifteen days. Group IV was given VPA+Vit U (in same dose and time). Vit U was given to rats by gavage and VPA was given intraperitoneally. On the 16th day of experiment, all the animals were fasted overnight and then sacrificed under ether anesthesia. Liver tissue was taken from animals, homogenized in 0.9% saline to make up to 10% homogenate. Liver aspartate and alanine transaminases, alkaline phosphatase, lactate dehydrogenase, myeloperoxidase, sorbitol dehydrogenase, glutamate dehydrogenase and xanthine oxidase activities and lipid peroxidation levels were increased and paraoxonase activity and glutathione levels were decreased in VPA group. Treatment with Vit U reversed these effects. These results demonstrated that administration of Vit U is a potentially beneficial agent to reduce the liver damage in VPA induced hepatotoxicity, probably by decreasing oxidative stress.
