Effects of acute pancreatitis on circulating lipids in dogs were evaluated by comparing the serum cholesterol and triglyceride concentrations and plasma lipoprotein electrophoretic patterns of 4 dogs with experimentally induced pancreatitis (EIP), 2 (healthy) sham-operated control (SOC) dogs, and 4 dogs with naturally acquired pancreatitis (NAP) with the concentrations and patterns of 23 healthy, nonoperated control (HNC) dogs. Blood samples were collected once from HNC dogs, 1 to 3 times during the course of the disease in dogs with NAP, and prior to and at 6, 12, 24, 48, 72, and 96 hours after induction of pancreatitis in dogs with EIP or after the sham operation in the SOC dogs. The dogs with EIP did not have turbid serum and did not develop hypercholesterolemia or hypertriglyceridemia. Three of the dogs with NAP had turbid serum and hypertriglyceridemia, and 3 had hypercholesterolemia. The electrophoretic tracings of HNC dogs had predominant alpha-1 peaks and small beta peaks; 2 of the HNC dogs also had small alpha-2 peaks. The tracings of dogs with EIP were similar to those of HNC dogs until 48 to 72 hours after induction of pancreatitis, when dogs with EIP developed increased beta lipoproteins, decreased alpha-1 lipoproteins, and movement of lipoproteins into the alpha-2 zone. The tracings of SOC dogs were similar to those of HNC dogs at all times. Compared with HNC dogs, dogs with NAP all had increased beta lipoproteins, and 2 had decreased alpha-2 lipoproteins. Two dogs with NAP had additional lipoprotein alterations, unlike any seen in dogs with EIP. 相似文献

OBJECTIVE: To characterise the lipid profiles in dogs with parvoviral enteritis. METHODS: Blood was collected before treatment from 30 dogs that fulfilled the criteria for severe sepsis including hypo- or hyperthermia, hypotension, leucopenia, thrombocytopenia and evidences of organ dysfunction. Canine parvovirus was detected by haemagglutination and indirect fluorescence antibody tests in the faeces. Twenty control dogs were also enrolled on the basis of normal physical examination results, complete blood count and serum biochemistry profiles. RESULTS: Tachycardia, tachypnoea, hypotension, leucopenia, thrombocytopenia and increased serum markers of tissue injury (alanine aminotransferase, creatinine kinase myocardial isoenzyme [CK-MB], blood urea nitrogen and creatinine) were observed in dogs with parvoviral enteritis. Serum total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol levels were lower, but serum triglyceride level was higher in dogs with parvoviral enteritis than those in control dogs (P<0.001). Circulating tumour necrosis factor alpha correlated negatively with total cholesterol (r=-0.979; P<0.001) but positively with triglyceride (r=0.953; P<0.001) in dogs with parvoviral enteritis. Serum total cholesterol and high-density lipoprotein cholesterol levels were lower in non-survival (n=9) dogs than in survival dogs (n=21, P<0.001). CLINICAL SIGNIFICANCE: Serum total cholesterol and high-density lipoprotein cholesterol levels decreased, but serum triglyceride level increased in dogs with parvoviral enteritis. Low serum total cholesterol and high-density lipoprotein cholesterol levels may be used as an index of the severity of parvoviral enteritis. 相似文献

Serum lipids and lipoprotein concentrations have been associated with dominance aggression in humans. The aim of this study was to investigate the link between serum lipids, including cholesterol, triglyceride, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC) to HDL-C ratio and dominance aggression in dogs. Levels of serum TC, triglyceride and HDL-C were significantly lower in dogs with dominance aggression compared with non-aggressive dogs (P < 0.001). These results suggest that a relationship exists between serum lipid profile and dominance aggression in dogs, and hypocholesterolaemia exists in dogs with dominance aggression. 相似文献

O bjective : To characterise lipid profile in dogs with tail chasing.
M ethods : Fifteen dogs with tail chasing were included in this study. A behavioural diagnosis was made for each dog on the basis of the dog's behavioural history, clinical signs and results of other medical assessments. None of the dogs had concurrent medical disease that would account for compulsive tail chasing. Blood samples were taken from each dog after a fasting period of 12 to 16 hours to measure total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and very low-density lipoprotein cholesterol levels. Fifteen control dogs were also enrolled on the basis of normal physical examination results, complete blood count and serum biochemistry profiles.
R esults : Dogs with tail chasing had significantly higher total cholesterol (P < 0·01), high-density lipoprotein cholesterol (P<0·05) and low-density lipoprotein cholesterol (P<0·001) compared with control dogs. Very low-density lipoprotein cholesterol and triglyceride levels did not differ significantly between the groups.
C linical S ignificance : Tail chasing may be associated with serum cholesterol elevations in dogs. High serum cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol levels may be used as biochemical parameters of compulsive tail chasing in clinical settings. 相似文献

OBJECTIVE: To determine effects of obesity and diet in dogs on plasma lipid and lipoprotein concentrations by assaying plasma leptin and ghrelin concentrations and determining total plasma cholesterol and triglyceride concentrations as well as the concentrations of cholesterol and triglycerides in various lipoprotein classes (ie, very-low-density, low-density, and high-density lipoproteins). ANIMALS: 24 Beagles; 12 lean (mean [+/- SEM] body weight, 12.7 +/- 0.7 kg) and 12 chronically obese (21.9 +/- 0.8 kg) dogs of both sexes, between 1 and 9 years old. PROCEDURES: Total plasma cholesterol and triglyceride concentrations; lipoprotein cholesterol and triglyceride concentrations; and plasma ghrelin, leptin, free fatty acids, insulin, and glucose concentrations were measured and compared between lean and obese dogs, both of which were fed a complete and balanced maintenance diet. Chronically obese dogs were subsequently fed a high-protein low-energy diet to evaluate effects of diet composition on plasma lipid and lipoprotein measurements. RESULTS: Chronic obesity resulted in a significant decrease in plasma ghrelin concentration and a significant increase in plasma leptin, cholesterol, and triglyceride concentrations in dogs. High total plasma cholesterol and triglyceride concentrations resulted from increased cholesterol and triglyceride concentrations in all lipoprotein fractions. In obese dogs, modification of diet composition resulted in beneficial effects on plasma lipid and leptin concentrations, even before weight loss was observed. CONCLUSIONS AND CLINICAL RELEVANCE: Correlations exist between obesity and plasma measurements (ie, lipoproteins, leptin, insulin, and ghrelin) commonly associated with obesity. Modification of diet composition to control energy intake improves plasma lipid and leptin concentrations in obese dogs. 相似文献

A family of five privately owned rough collie dogs was referred for corneal lipidosis and also suffered from hypercholesterolaemia. The hypercholesterolaemia was characterised by an increase in the alpha-2 high density lipoprotein-1 band and was due to an increase in the cholesterol content of the very low density lipoprotein, low density lipoprotein and possibly the high density lipoprotein-1 fractions. A low-fat and energy-restricted diet did not reduce either total cholesterol or the corneal lipidosis. Corneal lipidosis regressed with short-chain fructo-oligosaccharide supplementation. However, the effects of short-chain fructo-oligosaccharides on total cholesterol were transient and variable. 相似文献

Alterations in serum lipid and lipoprotein concentrations in ponies with experimentally induced liver disease were investigated. Hepatocellular damage was induced, using a nonlethal dose of carbon tetrachloride. In a separate group of ponies, obstructive jaundice was induced by surgical ligation of the common bile duct. Over a 6-day period, blood samples were obtained from ponies after treatment with carbon tetrachloride and for 12 days in ponies subjected to surgery. Serum cholesterol and triglyceride concentrations were unaffected in both groups of ponies, except for significantly (P less than 0.01) high triglyceride concentration in ponies of the ligated group during the second postsurgical week. This increase was most likely attributable to anorexia observed during that period. Hyperbilirubinemia was observed early in ponies of the ligated group; most of the bilirubin was of the conjugated type. Using electrophoretic and ultracentrifugal methods, serum lipoprotein alterations were detected only in ponies of the ligated group. Increases of very low-density and low-density lipoprotein cholesterol concentrations and decrease in high-density lipoprotein cholesterol concentration were found. Although no changes were seen in total serum cholesterol concentration, a redistribution of lipoprotein cholesterol was observed in ponies of the ligated group. Similar alterations in lipoprotein distribution have been found in dogs, rats, and human beings with obstructive jaundice and cholestasis. The association between serum lecithin:cholesterol acyl transferase activities and these lipoprotein alterations remains to be elucidated. 相似文献

BACKGROUND: Lipid transport systems in animals have been evaluated both as experimental models for lipid and lipoprotein metabolism in humans and to gain insight into the lipid metabolism of specific breeds. The Turkman horse is a pure-blooded horse that lives on the margins of the Caspian Basin; information about serum lipids and lipoproteins in this breed is lacking. OBJECTIVE: The purpose of this study was to evaluate serum lipid and lipoprotein concentrations in clinically healthy Turkman horses. METHODS: Concentrations of triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDL-C), and very low density lipoprotein cholesterol (VLDL-C), and lipoprotein electrophoretic patterns were determined in serum samples from 48 Turkman horses of both sexes and 0-12 years of age. Results were analyzed by 1-way ANOVA. RESULTS: In both sexes and all age groups, the relative percentages of LDL-C (44.2-64.3%) were higher than those of HDL-C (29.7-47.1%) and VLDL-C (5.9-9.0%). Serum concentrations of TG and TC were significantly higher in male (0.45 +/- 0.12 mmol/L; 2.70 +/- 0.45 mmol/L) than in female (0.34 +/- 0.1 mmol/L; 2.15 +/- 0.3 mmol/L) horses in most age groups. The relative percentages of alpha- and beta-lipoproteins in electrophoretic tracings were 62.77 +/- 5.05% and 36.67 +/- 4.29%, respectively. CONCLUSION: Serum lipid and lipoprotein values in Turkman horses differ from those of other equine breeds, and may be useful for evaluating metabolic diseases in this species. 相似文献

Two dogs with cloudy aqueous humor due to accumulation of lipid and lipoprotein had concurrent hyperlipemia and anterior uveitis. In 1 dog, serum and aqueous humor had similar lipoprotein electrophoretic patterns, and in the other dog, the patterns were different. The therapeutic approach included symptomatic treatment of the uveitis and reduction of dietary fat intake. Clearing of fat from aqueous humor followed control of the uveitis. 相似文献

OBJECTIVE: To compare serum triglyceride concentrations obtained after food had been withheld (i.e., fasting concentrations) in dogs with epilepsy that had been treated long term (> or = 3 months) with phenobarbital or with phenobarbital and potassium bromide with concentrations in healthy control dogs. DESIGN: Cross-sectional study. ANIMALS: 57 epileptic dogs that had been treated with phenobarbital (n=28) or with phenobarbital and bromide (29) and 57 healthy, untreated control dogs matched on the basis of age, breed, sex, neuter status, and body condition score. PROCEDURES: Blood samples were collected after food had been withheld for at least 12 hours, and serum biochemical and lipid concentrations were determined. Oral fat tolerance tests were performed in 15 control dogs and 9 dogs with epilepsy treated with phenobarbital alone. RESULTS: 19 of the 57 (33%) epileptic dogs had fasting serum triglyceride concentrations greater than the upper reference limit. Nine (16%) dogs had a history of pancreatitis, and 5 of the 9 had high fasting serum triglyceride concentrations at the time of the study. A significant relationship was found between body condition score and fasting serum triglyceride concentration in all dogs, but serum triglyceride concentration was not significantly associated with phenobarbital dosage or serum phenobarbital concentration. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that dogs treated long term with phenobarbital or with phenobarbital and bromide may develop hypertriglyceridemia. Fasting serum triglyceride concentration should be periodically monitored in dogs treated with phenobarbital because hypertriglyceridemia is a risk factor for pancreatitis. 相似文献

Pleural effusions from 23 dogs and 25 cats hospitalized between November 1986 and April 1987 at the Veterinary Hospital of the University of Pennsylvania (VHUP) were classified as chylous (chylomicrons present) or nonchylous (chylomicrons absent) by the presence or absence, respectively, of a chylomicron band on lipoprotein electrophoresis gels of the effusions. Triglyceride concentrations, cholesterol concentrations, and cholesterol/triglyceride (C/T) ratios were compared between the chylous and nonchylous groups in each species. Cholesterol concentrations were not significantly different between chylous and nonchylous effusions in both dogs and cats. Cholesterol/triglyceride ratios of less than 1 were present in all dogs and cats with chylous effusions; however, 12% of dogs with nonchylous effusions and 50% of cats with nonchylous effusions also had a C/T ratio less than 1. Triglyceride concentrations accurately classified all effusions as chylous or nonchylous in both dogs and cats. Pleural effusions with triglyceride concentrations greater than l00 mg/dl were chylous in all cases, whereas, effusions with triglyceride concentrations less than l00 mg/dl were nonchylous in all cases. 相似文献

Concentrations of serum lipid components, lipid peroxide (LPO) and α-tocopherol and electrophoretic patterns of lipoproteins in serum samples obtained from captive marine mammals and terrestrial mammals were compared. Serum concentrations of total cholesterol, free fatty acid, and phospholipid in fish-eating animals were significantly higher than those in manatees and cows. Serum LPO and α-tocopherol concentrations in the fish-eating animals were also significantly higher than those in manatees, cows and dogs. Different patterns of densitometric scans of low density lipoprotein (LDL) and a significantly lower percentage of LDL were demonstrated in the dolphins compared with the seals, cow and dogs. The concentration of LPO was significantly correlated with triglyceride and phospholipid concentrations in serum from the dolphins. These results suggest that triglyceride and phospholipid are susceptible to oxidative reaction in fish-eating animals. Evaluation of serum lipids, LPO and α-tocopherol concentrations is needed for nutritional husbandry for fish-eating animals. 相似文献

OBJECTIVE: To determine the lipid composition and electrophoretic pattern of plasma lipoproteins in samples obtained from healthy 1-humped camels (Camelus dromedarius). ANIMALS: 34 healthy camels raised under similar farming and dietary conditions. PROCEDURES: Plasma samples were subjected to density-gradient ultracentrifugation for separation of plasma lipoproteins, including very-low-density lipoproteins (VLDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). Purity of the separation was assessed by use of polyacrylamide gel disk electrophoresis. Concentrations of triglycerides, cholesterol, and phospholipids were measured in each lipoprotein fraction, and lipoprotein electrophoretic patterns were determined in plasma samples. RESULTS: Phospholipid was the major constituent of VLDL (mean +/- SD concentration, 10.62 +/- 1.2 mg/dL), LDL (24.66 +/- 3.12 mg/dL), and HDL (38.08 +/- 0.76 mg/dL). Low-density lipoprotein, VLDL, and HDL were important plasma lipoprotein carriers for cholesterol (67.94 +/- 9.51%), triglyceride (55.83 +/- 7.81%), and phospholipid (51.91 +/- 1.55%), respectively. On the basis of electrophoresis results, relative percentages of alpha- and beta-lipoproteins were 31.72 +/- 4.88% and 68.3 +/- 4.68%, respectively. CONCLUSIONS AND CLINICAL RELEVANCE: The lipoprotein profile in 1-humped camels differed substantially from that of other ruminants. Results may be useful in the evaluation of metabolic disorders in camels. 相似文献

Effects of dexamethasone on pancreatic tissue and on serum amylase and lipase activities in dogs 总被引：2，自引：0，他引：2
J Parent 《Journal of the American Veterinary Medical Association》1982,180(7):743-746
The effects of dexamethasone on the pancreas and on pancreatic amylase and lipase activities were determined in clinically normal dogs and in dogs with neurologic disease. Dexamethasone increased serum lipase activity without any histologic damage to the pancreas in either group of dogs. It decreased serum amylase activity in the normal dogs and had a variable effect in dogs with neurologic disease, with or without confirmed pancreatitis. It was suggested that high serum lipase activity in dexamethasone-treated dogs may not be attributable to pancreatitis and that the reasons are still unknown. It was concluded that high serum lipase activity is an unreliable basis for diagnosis of pancreatitis in dogs treated with dexamethasone. The data allowed no conclusion about an additive effect of dexamethasone and neurologic disease causing pancreatitis. 相似文献

Relationship between the serum concentrations of serotonin and lipids and aggression in dogs 总被引：1，自引：0，他引：1
The serum concentrations of serotonin and lipids--triglycerides, total cholesterol, low density lipoprotein, high density lipoprotein and very low density lipoprotein--were determined in 18 normal dogs and 23 dogs diagnosed as aggressive on the basis of interviews with their owners and an assessment of their behaviour with reference to a canine overt aggression chart. The serum serotonin levels in the aggressive dogs were significantly lower than in the normal dogs (P<0.01), but the differences in serum lipids between the two groups were not statistically significant. 相似文献

Serum protein values were determined in 26 healthy dogs using agarose gel electrophoresis (SPE), splitting the electrophoretic separation into six regions: albumin, alpha(1), alpha(2), beta(1), beta(2)and gamma globulins. High-resolution electrophoresis (HRE) was used to separate single proteins. Serum proteins from dogs (26 healthy and 20 affected by various diseases) were then characterized by electrophoretic immunofixation (IFE) and Sudan black staining on HRE film. Haemoglobin and normal canine plasma and serum were used to identify haptoglobin and fibrinogen, respectively.In the standard pattern, determined by HRE, the following proteins were identified: albumin, alpha(1)-lipoprotein (alpha(1)-region), haptoglobin and alpha(2)-macroglobulin (alpha(2)-region), beta -lipoprotein and C3 (beta(1)-region), transferrin and IgM (beta(2)-region), IgG (mostly in gamma -region and partly in beta(2)-region). The HRE pattern shown by healthy dogs could be compared with those of dogs affected by various diseases to obtain clinical information. 相似文献

Plasma lipoprotein cholesterol in 64 clinically healthy Shetland sheepdogs was evaluated to assess whether the breed is more susceptible to hypercholesterolemia. The incidence of hypercholesterolemia was clearly higher in Shetland sheepdogs and mean plasma cholesterol level was significantly higher in Shetland sheepdogs than in control dogs. Blood biochemical examinations did not evidence the abnormalities, which imply the causative disorders, and thyroid hormone levels were not significantly different from the controls. These results suggest that the cholesterolemia is a primary disorder. Cholesterol fractionation by agarose gel electrophoresis and ultracentrifugation revealed that accumulation of alpha2-migrating lipoproteins was the common characteristic of dogs showing cholesterol level over 250 mg/dl in the breed. Increase in prebeta-beta-lipoproteins was also found in Shetland sheepdogs with marked hypercholesterolemia over 500 mg/dl. Therefore. Shetland sheepdogs may include more dogs with primary disorders in lipoprotein metabolism, which cause hypercholesterolemia. at least in Japan. 相似文献

The objectives of this study were to survey clinics’ guidance about recommended
fasting duration (FD) prior to lipoprotein analysis, and to characterize lipoprotein
cholesterol and triglyceride concentrations in obese and overweight dogs categorized on
the basis of the 5-point body condition score (BCS) scale. A dataset was created from
lipoprotein analysis medical records of 1,538 dogs from 75 breeds in 354 clinics from 2012
to 2013. A phone survey was conducted to obtain the clinics’ FD. Two-level linear
mixed-effects models were applied to the data. Over 50% of the clinics said they
recommended fasting for 12 hr or more. Dogs in clinics with FD 12 hr or more had lower
chylomicron triglyceride concentrations than those in clinics with FD less than 8 hr
(P=0.05). Mean (± SEM) BCS at sampling was 3.7 ± 0.02. Obese and
overweight dogs had higher very low density lipoprotein (VLDL) and high density
lipoprotein (HDL) cholesterol and triglyceride concentrations than ideal dogs
(P<0.05), but no such difference was found for low density
lipoprotein cholesterol and triglyceride concentrations (P≥0.07). Across
all BCS, as dog age rose from 0 to 8 years old, HDL cholesterol concentrations decreased
by 13.5 mg/dl, whereas VLDL triglyceride concentrations increased by 81.7
mg/dl (P<0.05). In conclusion, FD of 8 hr or less
may affect lipoprotein lipid concentrations. Obese and overweight dogs were characterized
as having high VLDL and HDL cholesterol and triglyceride concentrations. 相似文献
