We investigated the apo-enzyme content of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in clinically normal and ill canine, feline, equine and bovine patients. Aminotransferase activity was measured with and without the addition of exogenous pyridoxal-5'-phosphate (P5P). The amount of apo-enzyme was expressed as the percentage change in aminotransferase activity with the inclusion of P5P. The results of aminotransferase assays without P5P (holo-enzyme activity) were highly correlated to the results obtained with P5P (total enzyme activity) in all four species (Spearman rank correlations > 0.980). The median apo-aminotransferase percentage in clinically normal patients was: 11% ALT and 0% AST in 115 dogs, 7% ALT and -5% AST in 50 cats, 6% AST in 46 horses and 9% AST in 50 cattle. The amount of apo-enzyme did not increase as holo-enzyme activity increased in any of the species. The apo-aminotransferase content was not significantly different in canine, feline and equine patients with diseases affecting the liver, kidney or musculature compared to clinically normal animals. The apo-enzyme content did not differ significantly between specific liver diseases in canine and feline patients. 相似文献

Serum activity of alanine aminotransferase (ALT) was consistently increased in dogs with canine X-linked muscular dystrophy (CXMD), a primary myopathy characterized by profound and on-going skeletal muscle necrosis. In order to determine whether the ALT was of liver origin, serum activity of creatine kinase (CK), aspartate aminotransferase (AST), ALT, and sorbitol dehydrogenase (SDH) obtained from dystrophic dogs was compared with enzyme activity present in clinically normal dogs. In dystrophic dogs at all ages tested, serum activity of CK, AST, and ALT was increased, and significant increases were present in dogs four weeks or older. In contrast, SDH activity in dystrophic dogs was not statistically different from values in clinically normal dogs. Ultrastructural examination of liver tissue revealed no evidence of hepatic degeneration in dystrophic dogs. It was concluded that increased serum activity of ALT in the dog may be associated with severe skeletal muscle degeneration, without concurrent hepatocellular necrosis. 相似文献

Long-term administration of phenobarbital has been reported to cause hepatic injury in dogs. Phenobarbital induces hepatic enzymes, and it may be difficult to distinguish the effect of enzyme induction on serum liver enzyme activities from actual hepatic damage. The hepatotoxicity of phenobarbital and the impact of enzyme induction on serum liver enzyme activity were investigated prospectively in 12 normal dogs. Phenobarbital was administered for 29 weeks at 5 mg per kilogram of body weight (range, 4.8— 6.6 mg/kg) PO q12h, resulting in therapeutic serum phenobarbital concentrations (20–40 μg/mL). Serum alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST), γ-glutamyltransferase (GGT), fasted bile acids (fBA), total bilirubin, and albumin were determined before and during treatment. Lateral abdominal radiographs, abdominal ultrasounds, and histopathologic examinations of liver tissue obtained by ultrasound-guided biopsy were performed before and during treatment. Radiographs revealed a moderate increase in liver size in most dogs. Ultrasonographic examination revealed no change in liver echogenicity or architecture. No evidence of morphologic liver damage was observed histopathologically. ALP and ALT increased significantly ( P < .05), GGT increased transiently, and albumin decreased transiently during the study. There were no significant changes in AST, bilirubin, and fBA. These results suggest that increases in serum ALP, ALT, and GGT may reflect enzyme induction rather than hepatic injury during phenobarbital treatment in dogs. Serum AST, fBA, and bilirubin, and ultrasonographic evaluation of the liver are not affected by the enzyme-inducing effect of phenobarbital and can therefore be helpful to assess liver disease in dogs treated with the drug. 相似文献

In a five-week feeding trial, 90 broiler chicks were used to study the response of serum and liver alanine aminotransferase (ALT) aspartate aminotransferase (AST), sorbitol dehydrogenase (SDH) and alkaline phosphatase following the replacement of varying levels (0, 20, 40, 60, 80 and 100 per cent) of fishmeal protein by soyabean meal protein. The results showed that both serum ALT and AST activities increased significantly (P less than 0.01) with the increasing levels of substitution of soyabean meal for fishmeal. Regression analysis showed a significant (P less than 0.01) positive correlation between ALT and AST activities and the level of soyabean meal substitution with correlation coefficient, r, of 0.93 and 0.98, respectively. The liver ALT and AST tended to increase with the increasing proportion of soyabean meal although such increases were not significant (P greater than 0.01). Serum and liver SDH and alkaline phosphatase activities were not significantly influenced by diet. 相似文献

To explore the acting mechanism of Pueraria extract on fatty liver hepatocytes in dairy cows. The hepatocytes in dairy cows were isolated by two-step collagenase perfusion method and observed. The hepatocytes cultured in vitro were treated with different concentrations of Pueraria extract. The activities and contents of ALT, AST, TG, SOD and MDA in the hepatocytes were detected by biochemical methods. Results showed that in the administration of Pueraria extract with the concentrations of 50,100 and 500 μg/mL could extremely significantly reduce the liver cells of ALT, AST, TG, TC, MDA activity and content, increase SOD activity (P < 0.01). The Pueraria extract had significantly therapeutic effect on dairy cows fatty liver of biochemical indexes. The mechanism might be related to regulate lipid metabolism and anti lipid peroxidation. 相似文献

The aim of the present investigation was to study the effect of a varying maternal vitamin B6 supplementation during lactation period on vitamin B6 levels in blood, liver and total body, and on the activity of two transaminase enzymes in the offspring. Therefore, eighty female Sprague-Dawley rats were fed a semi-synthetic diet (0.2 mg vitamin B6 per kg) which was supplemented during gravidity with 5 mg vitamin B6 per kg diet. During the following lactation period the rats were assigned to one of 10 vitamin B6 treatment groups (supplementation of 0, 3, 6, 9, 12, 15, 18, 36, 360, 3600 mg vitamin B6 per kg diet). At day 14 of lactation the pubs of all dams were decapitated and blood, liver, and carcass were used for analysis of vitamin B6 concentration, activities of two transaminases, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in plasma, erythrocytes, and liver, and of haematological parameters. While the liver and total body wet weights as well as the haematological parameters (red blood cells, haemoglobin concentration, hematocrit, middle corpuscular cell volume, middle corpuscular haemoglobin, middle corpuscular haemoglobin concentration) did not differ within the experimental groups, the present data clearly show that in blood, liver and total body of the offspring exists a slight dose-response relationship between the maternal dietary vitamin B6 supplementation and the vitamin B6 concentration. Concerning the activities of the transaminases a dietary supplementation above 3 mg vitamin B6 per kg diet had no influence on the AST and ALT activities in offspring plasma. In the erythrocytes no statistical significant influence of the vitamin B6 supplementation during lactation on the activities of AST and ALT was found. The activities of ALT and AST in liver were not consistently altered by the vitamin B6 supplementation of the dams during lactation. In conclusion these results indicate that a minimal maternal dietary vitamin B6 supply of 3.1 mg per kg diet is necessary with regard to health and development of their offspring. But not all of the analysed parameters as the liver and total body weights, the activities of AST and ALT in the erythrocytes, and the haematological parameters were influenced by a deficient maternal dietary vitamin B6 supply. 相似文献
