Serum protein electrophoresis in canine parvovirus enteritis     

A H van den Broek 《The British veterinary journal》1990,146(3):255-259

The serum protein concentrations of dogs with confirmed canine parvovirus enteritis were determined by agarose gel electrophoresis before treatment. A significant decrease was detected in the mean concentration and percentage of albumin and gammaglobulin and the percentage of alpha-1-globulin. The mean concentration and percentage of alpha-2-globulin were significantly increased.  相似文献   

Onion poisoning of young cattle     

J Verhoeff  R Hajer  T S van den Ingh 《The Veterinary record》1985,117(19):497-498

Eighty-five cattle (calves and yearlings) were allowed 1000 kg of onions (Allium cepa) a day. Signs of poisoning were observed after five days; 22 animals were affected, one fatally. New illnesses continued to occur for five days after the withdrawal of onions from the diet. Clinical signs included inappetance, tachycardia, staggering and collapse, with jaundiced conjunctivae and haemoglobinuria. Haemolytic anaemia with Heinz bodies in the red cells and leucocytosis were demonstrated.  相似文献   

Aujeszky's disease in a horse     

T S van den Ingh  G J Binkhorst  T G Kimman  J Vreeswijk  J M Pol  J T van Oirschot 《Zentralblatt für Veterin?rmedizin. Reihe B. Journal of veterinary medicine. Series B》1990,37(7):532-538

A horse with neurological signs and severe meningoencephalitis caused by Aujeszky's disease is described. The diagnosis was established by immunohistochemistry, DNA-in situ hybridization and serological tests. Aujeszky's disease virus antigen and Aujeszky's disease viral DNA were detected in neurons of the cerebrum. In the serum of the horse antibodies against Aujeszky's disease virus were detected in a virus neutralization test, in a blocking ELISA which specifically detects antibodies against the glycoprotein I (Ig) of the virus, in an indirect double sandwich ELISA and with colloidal gold immunoelectron microscopy which detects antibodies directed against the envelope and nucleocapsid of the virus. Intranasal infection of two points with a high dose of Aujeszky's disease virus caused very wild and transient signs. Although the experimental infection induced virus neutralizing antibodies, it failed to induce gI specific antibodies.  相似文献   

Extrahepatic cholestasis in the dog and the differentiation of extrahepatic and intrahepatic cholestasis     

T S van den Ingh  J Rothuizen  W E van den Brom 《The Veterinary quarterly》1986,8(2):150-157

The clinical and pathological features of extrahepatic cholestasis in 19 dogs are presented. The condition was most often caused by partial or complete occlusion of the choledochal duct due to neoplastic diseases (12 cases), inflammatory processes (3 cases), or eventration and incarceration of the liver (1 case). In only three cases was the condition due to intraluminal obstruction of the choledochal duct. The anamnestic, laboratory and pathological parameters of these 19 dogs were compared with the findings in 21 dogs with intrahepatic cholestasis. Statistical analysis of these parameters indicated that the presence of acholic faeces, the degree of icterus and the level of plasma gamma GT where the only parameters of value in the clinical differentiation of extrahepatic from intrahepatic cholestasis. Histological examination of liver biopsies is a simple aid to a confident in vivo diagnosis of extrahepatic cholestasis.  相似文献   

A retrospective study of gastrointestinal disorders in a predominantly Austrian leisure horse referral hospital population     

V. Gunes  A. C. Onmaz  A. Pavaloiu  G. Kaya Karasu  R. van den Hoven 《Equine Veterinary Education》2022,34(9):467-472

The aim of our retrospective study was to produce and analyse epidemiological data on gastrointestinal (GI) disorders of Austrian leisure horses. Case records of horses referred to the Equine Clinic of the Veterinary University of Vienna were collected from an electronic hospital information system using its search options. All cases reported to have suffered a GI disorder between March 2003 and February 2015 were selected. In this period of 4314 days, data of 1833 GI cases, mostly accompanied by colic signs, were analysed. The vast majority of our GI cases appeared in the abdominal parts of the GI tract 96% (1760/1833) while just 1.3% (24/1833) could be definitively attributed to oesophageal disorders, whereas in 2.7% (49/1833) of the cases a definitive diagnosis could not be made. The highest prevalence of GI disorders was seen in July and October/November. A breakdown of figures for cases clustered under the colic syndrome showed that colon impactions in left ventral large and/or pelvic flexure (35%) were the major problem followed by gastric disorders (18%), spasmodic colic (9%), enteritis (7%), caecal tympany (6%); caecal impaction (4%), colitis (3%), abnormal anatomical positions of large colon including complete and partial strangulation/volvulus, nephrosplenic entrapment of the left ventral and dorsal colon and right dorsal displacement of the large colon (3%) and small intestinal volvulus (2.7%). In 12% of the cases, the cause of the abdominal discomfort was likely idiopathic paralytic ileus. The searching tool of the electronic patient data also brought up cases with malabsorbtion/IBD syndrome and GI ruptures, both these contributed less than 1% of the referred GI cases. Results suggested that the causes of colic are diverse, but the major reasons for referred cases of colic in the east Austrian horse population are large colon impaction or displacements. Seasonal distribution and specific causes of gastrointestinal disorders should be considered essential components of the initial clinical assessment of horses presenting with colic.  相似文献   

Squamous gastric ulceration complicated by gastric stenosis in a foal     

P. Witt  L. de Kroon  N. Ankringa  M. Delany  L. W. L. van Bruggen  R. van den Boom  M. M. Sloet van Oldruitenborgh-Oosterbaan  E. W. Siegers 《Equine Veterinary Education》2022,34(9):e369-e374

A 2-month-old Warmblood colt presented with recurrent colic and regurgitation. Gastroscopy, performed on several occasions, and barium-contrast radiography revealed severe squamous gastric ulceration and stenosis at the level of the margo plicatus. Treatment with omeprazole reduced the extent and severity of the gastric ulcers but did not affect the stenosis. The foal was euthanised because of a poor prognosis, and post-mortem examination confirmed the clinical diagnosis. Severe squamous gastric ulceration, granulation tissue formation and cicatrisation of deep gastric lesions were considered to have caused the stenosis. Gastroduodenal outflow obstruction is a recognised disorder in foals, but stenosis at the level of the margo plicatus has not been reported in foals or adult horses. To the authors' knowledge, this is the first case of severe squamous gastric ulceration, complicated by stenosis at the level of the margo plicatus, in a foal. Although rare, gastric stenosis should be considered in foals suffering recurrent colic and regurgitation.  相似文献   

不同退化程度高寒草甸植物物种多样性与生态系统多功能性关系

为探究高寒草甸不同退化程度生态系统多功能性的变化,本研究综合考虑了植物物种多样性和多种生态系统功能如生产力、养分循环和固存能力、土壤涵养水分能力等,运用降维因子分析的方法计算了生态系统多功能性,综合分析了植物物种多样性与生态系统功能和多功能性间的关系。结果表明：高寒草甸退化显著降低了Margalef指数、Shannon-weiner指数、Simpson指数和Pielou指数(P<0.05),各生态系统功能趋于恶化。高寒草甸退化导致生态系统多功能性的下降,综合统计量结果为轻度退化(21.9955)＞中度退化(8.7295)＞重度退化(—30.7245)。植物物种多样性与生态系统多功能性之间均存在正相关关系,其中Simpson指数与生态系统多功能性指数拟合的结果最好,说明高寒草甸生态系统多功能性受植物物种多样性的制约。本研究可为青藏高原草地退化及恢复的过程和机理研究提供理论依据。  相似文献   

Effects of nitrogen and phosphorus fertilization on the growth and nutrition of hybrid poplars on Vancouver Island     

K. R. Brown  R. van den Driessche 《New Forests》2005,29(1):89-104

The effects of nitrogen (N) and phosphorus (P) rates, P source, and method of P application were tested on growth and nutrition of four clones of hybrid poplar (Populus trichocarpa Torr. & Gray×P. deltoides Bartr. ex Marsh or P. trichocarpa×P. maximowiczii A. Henry) in a plantation on Vancouver Island. Treatments were applied shortly after planting. Nitrogen (0, 500kgNha^–1) was supplied as ammonium sulfate (AS); half of the AS was added at the start of the second growing season. Phosphorus (0, 100, 200kgPha^–1) was supplied as triple super phosphate (TSP), rock phosphate (RP), or diammonium phosphate (DAP) and banded or broadcast. Over four growing seasons, stem volumes increased with AS and P additions. The effects of AS and P each were greatest when the other was also added. Volume was greater when P was applied at 100kgha^–1 than in the P control and did not significantly increase further at 200kgPha^–1. Phosphorus additions were more effective when added as TSP or DAP than when added as RP, but only in P100 and when banded. Banding increased volume when P was applied at 200kgha^–1, but increases were significant only for DAP fertilized trees. Roto-tilling associated with the banding treatment also increased volume when AS and P were not added. Rankings of clones with respect to stem volume varied with N supply and changed over time.  相似文献
