OBJECTIVE: To validate a luciferase bioassay, which is based on a recombinant mouse hepatoma cell line, for the detection of exposure to petroleum in mustelid species. ANIMALS: 122 American mink (Mustela vison) and 15 sea otters (Enhydra lutris). PROCEDURES: Mink were exposed to Bunker C fuel oil or Alaska North Slope crude oil externally as a single exposure or internally via low dose concentrations in their ration for 6 months. Serum samples were analyzed for cytochrome P450 1A1 induction by quantification of luciferase activity in the bioassay. Mink liver specimens were also evaluated for cytochrome P450 1A1 induction by quantification of ethoxyresorufin-o-deethylase activity. Serum collected from exposed and unexposed sea otters was also analyzed using the luciferase bioassay. RESULTS: Serum samples from mink externally exposed to petroleum had significantly increased luciferase activities at 1 week after exposure. Serum samples taken at later time points or from mink exposed to either product in the ration did not cause significant luciferase induction. Samples from otters exposed to petroleum had significantly higher luciferase induction as compared with samples from otters not exposed to petroleum at 2 and 8 years after the spill. Cytochrome P450 1A1 activity in liver specimens collected from mink that were internally exposed through diet was significantly increased at the conclusion of our study. CONCLUSION AND CLINICAL RELEVANCE: The luciferase bioassay is a sensitive and specific method for determining recent exposure to petroleum in mink. The lack of luciferase activity in serum samples collected from mink greater than 1 week after experimental exposure was likely attributable to lower overall petroleum exposure in our trial, compared with natural exposures. 相似文献

Otic medications containing triamcinolone or dexamethasone were administered twice daily for 21 days to 2 groups of 4 healthy dogs each. Serum alkaline phosphatase, gamma-glutamyltransferase, alanine transaminase, and aspartate transaminase activities, and serum bile acid and lipoprotein-X concentrations were assayed for 35 days. Increased serum activities for gamma-glutamyltransferase, alkaline phosphatase, and alanine transaminase were detected by day 7 and peaked at day 21. Increases were greater in dogs given the dexamethasone-containing medication. Enzyme activity returned to baseline by day 35. Serum aspartate transaminase activity and bile acid and lipoprotein-X concentrations did not increase. 相似文献

The following parameters were determined in blood serum of apparently healthy Bennett's wallabies (Macropus rufogriseus) using the Hitachi 917 (Roche Diagnostics, Mannheim, Germany) and/or the Vettest 8008 (IDEXX-GmbH, Woerrstadt, Germany): alkaline phosphatase, alanine aminotransferase, ammonia, alpha-amylase, aspartate aminotransferase, Ca, Cl, cholesterol, cholinesterase, creatine kinase, creatinine, gammaglutamyltransferase, glucose, iron, lactate dehydrogenase, magnesium, phosphate, potassium, protein, sodium, total bilirubin, triglyceride, and urea. The results for cholesterol, glucose, total protein, triglyceride and for the enzymes alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, gamma-glutamyltransferase and lactate dehydrogenase differed significantly between both methods (P < 0.05). There is a negative correlation between the age of the Bennett's wallabies and the activity of the alkaline phosphatase. Five protein fractions could be separated on cellulose acetate electrophoresis. The mean concentrations of fructosamine and beta-hydroxybutyrate were 447.3 micromol/L and 0.27 mmol/L, respectively. The estimated vitamin A intake had no influence on the vitamin A concentration in serum. The serum vitamin E concentration was in general low and vitamin E was below the detection limit of 0.82 micromol/L in 29 out of 42 serum samples. The use of these analytes is discussed concerning the knowledge about the physiology, nutrition and diseases of macropods. 相似文献

OBJECTIVE: To determine the effect of age on reference intervals of serum biochemical values in kittens. DESIGN: Prospective clinical trial. ANIMALS: 55 kittens from 12 specific-pathogen-free queens. PROCEDURE: Kittens were allocated at birth into colostrum-fed (n = 27) and colostrum-deprived (28) groups. Blood was collected at birth and on days 1, 2, 4, 7, 14, 28, and 56. Serum samples were analyzed for activities of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, creatine kinase, lactate dehydrogenase, gamma-glutamyltransferase, amylase, and lipase and for concentrations of albumin, total protein, bilirubin, urea nitrogen, creatinine, cholesterol, glucose, calcium, phosphorus, and triglycerides by use of an automated analyzer. Total serum solids concentrations were determined by use of refractometry. Serum IgG concentrations were quantified by use of radial immunodiffusion. RESULTS: For several analytes, reference intervals changed rapidly, most notably during the first few days of life. Reference intervals for alkaline phosphatase, creatine kinase, lactate dehydrogenase, and triglycerides were higher from birth to 8 weeks than adult reference intervals. Aspartate aminotransferase, bilirubin, urea nitrogen, and creatinine were higher than in adults at birth but were similar to or lower than adult reference intervals by 8 weeks. Compared with adult reference intervals, reference intervals for calcium and phosphorus concentrations were higher and for albumin and total protein concentrations were lower throughout the study period. CONCLUSIONS AND CLINICAL RELEVANCE: Important differences exist between reference intervals for serum biochemical values of neonatal and adult cats. Age-appropriate reference intervals should be used for accurate assessment of serum biochemical test results in cats. 相似文献

Blood vessel walls are shown to contain creatine phosphokinase, lactate dehydrogenase, gamma glutamyl transpeptidase and aspartate transaminase activity. The activity of these enzymes in the serum may be enhanced by leakage from damaged blood vessels.The activity of the enzymes alanine transaminase and alkaline phosphatase as well as the content of triglycerides, cholesterol and lipoproteins are very low in the vascular tissue and are unlikely to be of diagnostic value in vascular tissue injury. 相似文献

Administration of trimethoprim-sulfadiazine in a dog was associated with vomiting, inappetence, and icterus, and high values of alanine transaminase, aspartate transaminase, alkaline phosphatase, gamma-glutamyltransferase, and total bilirubin concentration. The clinical signs and biochemical abnormalities resolved after discontinuation of the treatment. Histologic examination of sections from a liver biopsy specimen revealed moderate, predominantly portal hepatitis with cholestasis. 相似文献

OBJECTIVE: To identify surrogate markers of passive transfer of immunity in kittens. DESIGN: Prospective clinical trial. ANIMALS: 55 kittens from 12 specific-pathogen-free queens. PROCEDURE: Kittens were allocated at birth into colostrum-fed (n = 27) and colostrum-deprived (28) groups. Blood was collected at birth and on days 1, 2, 4, 7, 14, 28, and 56. Serum samples were analyzed for activities of alkaline phosphatase (ALP), alanine aminotransferase, aspartate aminotransferase, creatine kinase, lactate dehydrogenase, gamma-glutamyltransferase, amylase, and lipase and for concentrations of albumin, total protein, bilirubin, urea nitrogen, creatinine, cholesterol, glucose, calcium, phosphorus, and triglycerides by use of an automated analyzer. Total serum solids concentrations were estimated by use of refractometry. Serum IgG concentrations were quantified by use of radial immunodiffusion. RESULTS: All kittens were agammaglobulinemic at birth. Colostrum-fed kittens had significantly higher IgG concentrations than did colostrum-deprived kittens from 1 though 28 days of age. Transient significant differences in serum biochemical variables between the colostrum-deprived and colostrum-fed groups were substantially resolved by day 4. Passive transfer of immunity could be reliably determined at 1 day of age and to a lesser extent at 2 days of age only by measurement of serum activity of ALP. CONCLUSIONS AND CLINICAL RELEVANCE: Adequacy of passive transfer in kittens initially correlated with serum activity of ALP, but quantification of serum IgG concentration was necessary after 2 days of age. 相似文献

Tissue and plasma enzyme activities in juvenile green iguanas 总被引:1,自引:0,他引:1
OBJECTIVE: To determine activities of intracellular enzymes in 8 major organs in juvenile green iguanas and to compare tissue and plasma activities. ANIMALS: 6 green iguanas < 1 year old. PROCEDURE: Lysates of liver, kidney, epaxial muscle, heart, lung, spleen, small intestine, and pancreas were analyzed for alkaline phosphatase (ALP), lactate dehydrogenase (LDH), aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyltransferase (GGT), creatine kinase (CK), glutamate dehydrogenase (GMD), and amylase (AMS) activities. RESULTS: In general, low tissue enzyme activity coincided with low plasma activity. The CK activity was high in epaxial muscle and the heart and low in all other tissues tested. The AMS activity was found exclusively in the pancreas. Moderate LDH and AST activities were found in all tissues. Low ALT and ALP activities were found in a variety of tissues. Plasma and tissue activities of GGT and GMD were low or undetectable. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that plasma CK activity may be muscle specific in iguanas, but high values may not always indicate overt muscle disease. The AMS activity may be specific for the pancreas, but the wide range of plasma activity would likely limit its diagnostic usefulness. Activities of AST and LDH may reflect tissue damage or inflammation, but probably do not reflect damage to specific tissues or organs. 相似文献

Heparinized blood samples from 15 adult small island flying foxes (Pteropus hypomelanus) were stored at 22 degrees C for 0-, 6-, and 24-hr intervals prior to centrifugation and separation of plasma from erythrocytes. Mean plasma biochemical values of 16 analytes were determined from all samples. Mean values of blood urea nitrogen, creatinine, total protein, albumin, globulin, alkaline phosphatase, alanine transaminase, aspartate transaminase, cholesterol, calcium, sodium, and bilirubin did not change significantly over 24 hr at 22 degrees C. Glucose was decreased at 6 and 24 hr. Potassium and phosphorus increased and chloride decreased, respectively, between 6 and 24 hr. 相似文献

OBJECTIVE: To determine the associations between serum IgG concentration and serum activities of gamma-glutamyltransferase (GGT), alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and pseudocholinesterase for the potential use of these serum enzymes as predictors of passive transfer status in neonatal lambs. DESIGN: Prospective observational study. ANIMALS: 47 Sardinian lambs from birth to 2 days old. PROCEDURE: Serum enzyme activities were measured by use of commercially available kits and a clinical biochemical analyzer. Serum IgG concentration was determined by single radial immunodiffusion. Associations between serum IgG concentration and the activity of each serum enzyme were established by use of regression analysis. RESULTS: A significant correlation was detected between serum IgG concentration and serum GGT activity in 1- and 2-day-old lambs. Minimal correlations were detected between serum IgG concentration and serum alkaline phosphatase activity in 1-day-old lambs and serum pseudocholinesterase activity in 1- and 2-day-old lambs. No significant associations were detected between serum IgG concentration and serum activities of aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase. A multiple linear regression model was accurate for the estimation of the natural logarithm of serum IgG concentration as a function of the natural logarithm of serum GGT activity and of the age of lambs at the time of sampling (adjusted R2 = 0.89). This model was then used to calculate the serum GGT activity equivalent to various serum IgG concentrations for 1- and 2-day-old lambs. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that passive transfer status in neonatal lambs can be successfully predicted by measurement of serum GGT activity but not by measurement of the other enzymes tested. 相似文献

Horses with third-degree perineal lacerations require surgical treatment. To reduce the risk of postoperative dehiscence of the surgical site caused by tension, bacterial contamination, and mechanical abrasion, a preoperative and postoperative fasting up to 14 days was performed. A complete blood cell count, concentrations of electrolytes, urea, creatinine, glucose, lactate, cholesterol, triglycerides, total protein, and the activities of aspartate aminotransferase, glutamate dehydrogenase, γ-glutamyl transferase, creatine kinase, and alkaline phosphatase were determined. Fasting resulted in a marked decrease in intestinal motility and an increase in the concentrations of triglycerides and cholesterol. The activity of the glutamate dehydrogenase increased three-fold during the presurgical period. The other biochemical values showed few fluctuations. Based on these data, we concluded that presurgical and postsurgical fasting causes no severe imbalances in the metabolism in mares. 相似文献

Analysis of canine and feline blood samples using the Kuadro in-house wet-reagent chemistry analyser
Papasouliotis K Dodkin S Murphy K Woloszczuk G Fleming M 《The Journal of small animal practice》2006,47(4):190-195
OBJECTIVES: Kuadro is a new wet-reagent biochemistry analyser that is available for in-house use. The aim of this study was to compare the results produced by this analyser with those obtained by a wet-reagent analyser (KoneLab 30i) that served as the reference instrument. METHODS: Blood samples from 80 clinical cases (40 dogs and 40 cats) were analysed for urea, creatinine, total proteins, albumin, glucose, cholesterol, alanine aminotransferase, alkaline phosphatase, total bilirubin, amylase, total calcium, and phosphate using both the reference and Kuadro instruments. RESULTS: Kuadro performed very well on canine and feline samples, showing clinically acceptable correlations (r value) (canine/feline) for urea (0.99/0.97), creatinine (0.99/0.98), total proteins (0.95/0.97), albumin (0.98/0.90), glucose (0.99/0.99), cholesterol (0.99/0.99), alanine aminotransferase (1.00/0.99), alkaline phosphatase (0.96/0.99), total bilirubin (1.00/1.00), amylase (0.98/0.96), and phosphate (0.91/0.92). The correlation for total calcium measurements was clinically unacceptable (0.78/0.83). CLINICAL SIGNIFICANCE: Urea, creatinine, albumin, glucose, cholesterol, alanine aminotransferase, and phosphate Kuadro values can be used interchangeably with those generated by the reference analyser. Alkaline phosphatase, amylase, and total proteins Kuadro values cannot be used interchangeably, as Kuadro overestimated alkaline phosphatase and amylase and underestimated total protein measurements. Kuadro significantly underestimated total calcium concentrations due to the shorter incubation time used by the Kuadro analyser compared with the incubation time used in the reference analyser assay system. 相似文献

The primary purpose of this study was to establish plasma biochemistry parameters for healthy recently wild-caught purple mouth moray eels (Gymnothorax vicinus) to provide a baseline of data for improved medical care in an aquarium or zoologic setting and for wild health assessments. Thirty-one clinically healthy purple mouth moray eels of unknown age and sex were caught from the wild, and were anesthetized 50 days following capture for blood collection from the ventral coccygeal vein. The median plasma biochemistry values were as follows: hematocrit = 21%, creatinine kinase = 2,100 U/L, lactate dehydrogenase = 97 U/L, aspartate aminotransferase = 88 U/L, alanine aminotransferase = 51 U/L, alkaline phosphatase 3,939 U/L, gamma-glutamyl transpeptidase = 1 U/L, amylase = 40 U/L, blood urea nitrogen = < 11 mg/dl, glucose = 21 mg/dl, calcium = 12.5 mg/dl, triglyceride = 206 mg/dl, creatinine = 0.1 mg/dl, cholesterol = 334 mg/dl, total bilirubin = < 0.1 mg/dl, phosphorus = 6.5 mg/dl, total protein = 4.2 g/dl, albumin = 1.5 g/dl, globulin = 2.7 g/dl, albumin/ globulin ratio = 0.6, sodium = 185 mmol/L, potassium = 3.7 mmol/L, and chloride = 175 mmol/L. Alkaline phosphatase isoenzyme results indicate that the majority of the plasma alkaline phosphatase is the liver isoenzyme. The data acquired in this study also provide baseline values for cholesterol and triglycerides in recently wild-caught moray eels to aid in monitoring elevations to these values in an aquarium setting over time so adjustments to the dietary regime may be utilized to prevent or improve conditions such as lipid keratopathy. 相似文献

This report describes the first case of idiopathic hypertrophic osteopathy (HO) in a cat. No causes for the bone pathology were found following evaluation of the physical and laboratory examinations (complete blood count, albumin, creatinine, urea, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase and gamma-glutamyltransferase and urinalysis), and after histopathological evaluation of organs at necropsy. Based on the radiographic, clinical and anatomopathological findings, idiopathic HO was diagnosed. 相似文献

OBJECTIVES: To investigate effects of phenobarbitone on serum activities of alanine aminotransferase, alkaline phosphatase and gamma-glutamyl transferase and concentrations of bilirubin, albumin, cholesterol and total protein in dogs. ANIMALS: Ten crossbreed experimental dogs and 10 client-owned dogs of mixed breeds treated chronically with phenobarbitone to control seizures. PROCEDURES: Experimental dogs were allocated to treatment (6 mg/kg oral phenobarbitone, n = 6) and control (no treatment, n = 4) groups in which serum biochemical tests were performed at intervals during a 3-month period. Biochemical tests were performed once on the 10 epileptic dogs. RESULTS: Phenobarbitone caused increased serum alkaline phosphatase activity but did not affect gamma-glutamyl transferase activity or bilirubin, cholesterol, albumin and total protein concentrations. Phenobarbitone had minimal effect on alanine aminotransferase activity. CONCLUSIONS: Individual dogs treated with phenobarbitone may have small increases in serum alanine aminotransferase activity and variable increases in alkaline phosphatase activity but are unlikely to have alterations in gamma-glutamyl transferase activity or bilirubin, cholesterol, albumin or total protein concentrations. 相似文献

Ten male Holstein-Friesian calves naturally infected by Mycobacterium paratuberculosis were experimentally re-infected orally at an average of 17 days. Monthly measurements were conduced of the following activities, in the period between post infection days 160 and 400: total protein (TPR), albumin (ALB), cholesterol (CHOL), triglycerides (TRIG), Zn and Cu concentrations as well as sorbitol dehydrogenase, lactate dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (alpha-HBDH), gamma-glutamyltransferase, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK), alkaline phosphatase and fructose-1,6-diphosphate aldolase (ALD). TPR, ALB, TRIG, and CHOL were reduced by day 400, in conjunction with disorders of digestion and absorption. Increased activities of CK, ALD, LDH, alpha-HBDH, AST and ALT primarily indicated damage to skeletal muscle and/or liver. Serum CK and ALD activities as well as TRIG and TPR concentrations may serve as aids to specific diagnosis of paratuberculosis, particularly in the advanced stage of the disease. 相似文献

A clinical biochemistry analyser designed specifically for veterinary use was used to analyse plasma samples from 24 vervet monkeys (Cercopithecus aethiops). Two millilitres of heparinised blood was collected from each of the 24 monkeys on four occasions at intervals of one week. Plasma was separated and analysed for the concentrations of triglycerides, cholesterol, total proteins, albumin, globulins, creatinine and blood urea nitrogen (BUN) and the activities of alkaline phosphatase (AP), lactate dehydrogenase (LDH), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and creatine kinase (CK). The tests were easy to perform, used small volumes of plasma, and yielded consistent results for most of the analytes. The activities of CK and AP, but not AST, appeared to be influenced by haemolysis, and there were significant individual variations in the activity of LDH. 相似文献

1. Enzyme activities were studied in blood plasma from Rhenish, Italian, Landes and Masseubian geese. 2. Strains used for liver production (Landes, Masseubian) showed higher activities of aspartate transaminase (AST) [EC 2.6.1.1], alanine transaminase (ALT) [EC 2.6.1.2] and fructose aldolase (FRA) [EC 4.1.2.13] while breeds with high egg production (Rhenish, Italian) had higher activities of both alkaline phosphatase (ALP) [EC 3.1.3.1] and acid phosphatase (ACP) [EC 3.1.3.2] 相似文献

OBJECTIVE: To describe cardiac lesions and identify risk factors associated with myocarditis and dilated cardiomyopathy (DCM) in beach-cast southern sea otters. ANIMALS: Free-ranging southern sea otters. PROCEDURE: Sea otters were necropsied at the Marine Wildlife Veterinary Care and Research Center from 1998 through 2001. Microscopic and gross necropsy findings were used to classify sea otters as myocarditis or DCM case otters or control otters. Univariate, multivariate, and spatial analytical techniques were used to evaluate associations among myocarditis; DCM; common sea otter pathogens; and potential infectious, toxic, and nutritional causes. RESULTS: Clusters of sea otters with myocarditis and DCM were identified in the southern aspect of the sea otter range from May to November 2000. Risk factors for myocarditis included age, good body condition, and exposure to domoic acid and Sarcocystis neurona. Myocarditis associated with domoic acid occurred predominantly in the southern part of the range, whereas myocarditis associated with S. neurona occurred in the northern part of the range. Age and suspected previous exposure to domoic acid were identified as major risk factors for DCM. A sample of otters with DCM had significantly lower concentrations of myocardial L-carnitine than control and myocarditis case otters. CONCLUSIONS AND CLINICAL RELEVANCE: Cardiac disease is an important cause of death in southern sea otters. Domoic acid toxicosis and infection with S. neurona are likely to be 2 important causes of myocarditis in sea otters. Domoic acid-induced myocarditis appears to progress to DCM, and depletion of myocardial L-carnitine may play a key role in this pathogenesis. 相似文献
