Serum liver enzyme activities in healthy Miniature Schnauzers with and without hypertriglyceridemia

OBJECTIVE: To determine whether hypertriglyceridemia in healthy Miniature Schnauzers is associated with high serum liver enzyme activities. DESIGN: Cross-sectional study. ANIMALS: 65 Miniature Schnauzers with serum triglyceride concentrations within the reference range (group 1), 20 Miniature Schnauzers with slightly high serum triglyceride concentrations (group 2), and 20 Miniature Schnauzers with moderately to severely high serum triglyceride concentrations (group 3). PROCEDURES: Questionnaires regarding each dog's medical history were completed, and serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and G-glutamyltransferase (GGT) activities were measured. RESULTS: Median serum ALP activity was significantly higher in group 3 than in group 1 or 2 dogs, but was not significantly higher in group 2 than in group 1 dogs. Median serum ALT activity was significantly higher in group 3 than in group 1 dogs, but was not significantly different between any of the other groups. Compared with group 1 dogs, group 2 and 3 dogs were significantly more likely to have high serum ALP activity (odds ratio, 26.2 and 192.6, respectively). Group 3 dogs also were significantly more likely to have high serum ALT activity (odds ratio, 8.0), serum AST activity (odds ratio, 3.7), and serum GGT activity (odds ratio, 11.3), compared with group 1 dogs. Group 3 dogs were significantly more likely (odds ratio, 31.0) to have > or = 2 high serum liver enzyme activities than were group 1 dogs. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that moderate to severe hypertriglyceridemia was associated with high serum liver enzyme activities in Miniature Schnauzers.     

Increased Serum Alanine Aminotransferase Activity Associated With Muscle Necrosis in the Dog

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.

Effects of long-term phenobarbital treatment on the liver in dogs

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.

龙葵对四氯化碳致小鼠急性肝损伤的保护作用

研究了龙葵对四氯化碳（CCl4）所致小鼠急性肝损伤的保护作用。将60只小鼠随机分成6组：正常对照组、模型组、龙葵高剂量组、龙葵中剂量组、龙葵低剂量组、阳性对照组（水飞蓟素）。给药7 d后除正常组外其余5组按10 mL/kg剂量给予0.35% CCl4 。分别检测血清中丙氨酸氨基转移酶（ALT）、天冬氨酸氨基转移酶（AST）和肝功能氧化指标：丙二醛（MDA）、超氧化物歧化酶（SOD）和谷胱甘肽过氧化物酶（GSH-Px）。通过统计学处理分析得出龙葵各剂量组与阳性对照组、正常组和模型组之间存在差异性。结果表明,通过龙葵高剂量组的保护作用可以使血清中ALT、AST活性和肝组织中的MDA含量、SOD和GSH-Px活力趋近于正常水平。证明龙葵对CCl4所致小鼠急性肝损伤有明显的保护作用。     

Alanine aminotransferase apoenzyme in dogs

Unusually low serum activity of alanine aminotransferase (ALT) was detected in a Rottweiler dog with gastric dilatation-volvulus. Activity of ALT in the same sample was found to be much higher (estimated increase of 14,225%) when measured by methods adding the cofactor pyridoxal-5'-phosphate (P5P), indicating that nearly all serum ALT was in the apoenzyme form. An investigation was undertaken to determine the frequency of high serum aminotransferase apoenzyme levels in dogs. Eighty canine serum samples submitted to the Clinical Pathology Laboratory at Cornell University were assayed for ALT and aspartate aminotransferase (AST) in the presence or absence of exogenous P5P. In 79 dogs, inclusion of P5P in the LAT assay resulted in a median decrease in AST activity of -6.3% (range -33.3% to 25.0%) in all 80 dogs. One dog had an increase of 336% in ALT activity after inclusion of P5P in the assay, but lacked a similar increase in AST activity. The reason for the high levels of ALT apoenzyme in the 2 dogs was not determined.

Study on Liver-protective Effect of Chinese Herbal Compound Probiotics on Acute Liver Injury Layers

This experiment was conducted to investigate the liver-protective effect of Chinese herbal compound probiotics (CHCP) on acute liver injury layers.One hundred and eight 1 day old hens were divided into 4 groups with 3 replicates in each group and 9 layers per replicate in trial 1.The layers in model groups Ⅰ to Ⅲ were gavaged with 10% (V/V) soybean oil solution of carbon tetrachloride (SCCl₄) according to 1,2 and 4 mL/(kg·BW) at 14,28 and 35 d,respectively.The layers in control group were gavaged with 2 mL/(kg·BW) soybean oil.In trial 2,sixty 1 d layers were divided into 5 groups:Control group (soybean oil),model control group(SCCl₄)and low-dose,middle-dose and high-dose CHCP group (SCCl₄+1‰ CHCP,SCCl₄+2‰ CHCP and SCCl₄+4‰ CHCP respectively).CHCP were used by drinking water since 7 days.SCCl₄ were gavaged according to 2 mL/(kg·BW) at 14 and 28 d.The results showed as follows:The model of layers liver damage could be built by intragastric administration of 2 mL/(kg·BW) 10%(V/V) SCCl₄ at 14,28 d respectively,with the signs of hepatic steatosis,severe vacuolar degeneration,nuclear condensation and necrosis.Compared to the model control group,the serum AST levels in low,medium and high dose CHCP groups were decreased by 4.35% (P > 0.05),7.57% (P > 0.05) and 9.79% (P < 0.05),the serum ALT levels in medium and high dose CHCP groups were decreased by 34.92% (P < 0.01),36.51% (P < 0.01),the serum total bilirubin content in medium and high dose CHCP groups were decreased by 25.49% (P < 0.01),27.45% (P < 0.01).The liver cell congestion was reduced to varying degrees in different dose CHCP groups,and the liver cell had no vacuoles,arranged in neat rows,abundant cytoplasm and uniform in different dose CHCP groups.In conclusion,2‰,4‰ CHCP could reduce hepatocyte necrosis,decrease the serum activities of ALT,AST and total bilirubin levels,and had protective effect on hepatic injury induced by SCCl₄.
