Acute nontraumatic hemoabdomen in the dog: a retrospective analysis of 39 cases (1987-2001)     

Pintar J  Breitschwerdt EB  Hardie EM  Spaulding KA 《Journal of the American Animal Hospital Association》2003,39(6):518-522

The medical records of 39 dogs with acute nontraumatic hemoabdomen were identified and reviewed. Anemia and hypoalbuminemia were identified in 36/37 (97%) and 25/33 (76%) dogs, respectively. Coagulopathies were identified in 26/31 (84%) dogs. When a definitive diagnosis was obtained, malignant neoplasia was diagnosed most frequently and occurred in 24/30 (80%) dogs. Hemangiosarcoma accounted for 21/30 (70%) diagnoses. Sixteen dogs underwent exploratory laparotomy, of which seven (44%) survived the perioperative period. Of the dogs that did not undergo surgery, 9/23 (39%) survived to be discharged from the hospital.  相似文献   

Comparison of opioid and alpha-2 adrenergic receptor binding in horse and dog brain using radioligand autoradiography     

Hellyer PW  Bai L  Supon J  Quail C  Wagner AE  Mama KR  Magnusson KR 《Veterinary anaesthesia and analgesia》2003,30(3):172-182

Objective To test the hypothesis that the distribution, density, and subtype of opioid and alpha (α)‐2 adrenergic receptors within the central nervous system (CNS) are significantly different between horse and dog. Study design Prospective experimental study. Animals Three dogs (3 years of age) and three horses (2–5 years of age). Animals were opioid‐ and α‐2 agonist‐free at the time of euthanasia. Methods Brain tissue was obtained at 126 days post‐surgery from dogs and 72 days post‐surgery from horses. The brains were removed, sectioned coronally into 1‐cm slabs, frozen in methylbutane, which was cooled by liquid nitrogen, and stored at ?70 °C. Receptor autoradiography was performed using established techniques. [³H]DAMGO, [³H]U‐69593, and [³H]RX821002 were used for mu (µ)‐opioid, kappa (κ)‐opioid, and α‐2 adrenergic‐binding assays, respectively. Species differences were analyzed separately for each major brain region by repeated measures anova for subregions followed by Fisher's protected Latin square design (LSD). p < 0.05 was considered significant. Results There was higher binding of µ‐opioid receptors in the frontal cortex, left somatosensory cortex, colliculus (mid‐brain), and granule cell layer of the cerebellum of horses than that of dogs. There was higher binding to κ‐opioid receptors in the frontal cortex of dogs compared to horses, whereas binding to κ‐opioid receptors in the cerebellum was higher in horses. Binding to α‐2 adrenergic receptors in the mid‐brain was significantly higher in dogs than in horses. There was higher binding of α‐2 adrenergic receptors in the dorsomedial and dorsolateral periaqueductal grey of dogs as compared to that of horses. Conclusion The results of this study show that the distribution of these receptors is different between horses and dogs. Further work is needed to understand the relevance of these differences to clinical responses to opioids and α‐2 adrenergic agonists in these species.  相似文献

Interventional catheterization for tachyarrhythmias.     

Kathy N Wright 《Veterinary Clinics of North America: Small Animal Practice》2004,34(5):1171-1185

Catheter ablation of cardiac tachyarrhythmias is unique among our therapeutic armamentarium because it offers the ability to cure certain tachyarrhythmias permanently without implanted devices. TICM that is not distinguishable from idiopathic DCM can also resolve once the underlying tachyarrhythmia is eliminated. Current techniques are best suited to tachyarrhythmias in which a point lesion or small linear burn would result in disruption of the tachyarrhythmia's substrate. The equipment and expertise required limit the availability of this treatment modality in veterinary medicine. Its success with SVTs (particularly those secondary to accessory pathways), however, make it a viable option for many owners, even if they must travel some distance to reach a center performing these procedures.  相似文献   

Urinary Bladder incarceration and Infarction by an Intra-Abdominal Fat Pad in a Virginia Opossum (Didelphis Virginiana)     

Ryan S. De Voe  DVM    Kathy A. Spaulding  DVM    Jack Rotstein  MD    David S. Rotstein  DVM  MPVM 《Veterinary radiology & ultrasound》2004,45(4):312-314

A 2.5-year-old, female opossum had acute stranguria. Based on radiography and ultrasonographic examination a cystic structure was identified in the caudal abdomen associated with bilateral hydroureter and hydronephrosis. This structure contained a neutrophilic fluid, determined to be urine. There was a neutrophilic leukocytosis. Serum chemistry values were within normal limits. The opossum was euthanized. An intra-abdominal fat pad incarceration of the urinary bladder above the trigone was present, resulting in complete obstruction of the urinary bladder and partial obstruction of the ureters. Vessels to the bladder were involved in the incarceration which resulted in vascular compromise and infarction of the bladder. Mild to moderate hydroureter and hydronephrosis were present.  相似文献   

ORCHITIS IN TWO DOGS WITH ROCKY MOUNTAIN SPOTTED FEVER     

Christopher P. Ober  DVM    Kathy Spaulding  DVM    Edward B. Breitschwerdt  DVM    David E. Malarkey  DVM  PhD    Barbara C. Hegarty  BA 《Veterinary radiology & ultrasound》2004,45(5):458-465

Two dogs with testicular swelling were sonographically diagnosed with orchitis and were subsequently diagnosed with Rocky Mountain spotted fever (RMSF). Use of both gray scale and color Doppler sonography allowed for differentiation of orchitis from neoplasia and torsion. While only experimentally induced RMSF is reported to cause orchitis in dogs, it should be considered in any dog with vascular insult to the testes, especially when other signs of systemic illness are involved.  相似文献

Cloning and analysis of the gene for a major surface antigen of Mycoplasma gallisepticum     

Spencer DL  Kurth KT  Menon SA  VanDyk T  Minion FC 《Avian diseases》2002,46(4):816-825

Myplasma gallisepticum infects a wide variety of gallineaceous birds including chickens, turkeys, and pheasants. Infection occurs both horizontally and vertically. Thus, control of the spread of M. gallisepticum to noninfected flocks is difficult. Continual monitoring is necessary to identify infected flocks even under the most stringent infectious control practices. Monitoring, however, is usually performed by measuring hemagglutination activity (HA) in serum, an insensitive and variable test. Variability in the HA test arises differences in agglutination antigen, changes in antigenic profiles of the M. gallisepticum strain, and variability in reading the agglutination reaction. Enzyme-linked immunosorbent assays (ELISAs) are the preferred method of testing because of the ease in obtaining sera and the sensitivity and reproducibility of the assays, but the ELISA suffers from a lack of standardization in the test antigen. The ELISA test will be more easily accepted once the test antigen has been standardized. To this end, we have identified, cloned, and characterized the gene for an antigen that has potential as a species-specific antigen for M. gallisepticum The gene codes for a 75-kD protein, P75, that is recognized during natural infections. Recombinant P75 is not recognized in immunoblots by convalescent sera produced in chickens infected with Mycoplasma synoviae, Mycoplasma gallinarum, and Mycoplasma gallinaceum or in turkeys infected with Mycoplasma meleagridis.  相似文献   

Movement and persistence of [14C]imidacloprid in sugar-beet plants following application to pelleted sugar-beet seed     

Fahimeh Westwood  Kathy M. Bean  Alan M. Dewar  Richard H. Bromilow  Keith Chamberlain 《Pest management science》1998,52(2):97-103

[¹⁴C]Imidacloprid was applied to pelleted seeds of sugar beet which were then grown in pots of field soil. Leaves, roots and soil were analysed at intervals up to 97 days after planting and the distributions of parent compound and of several metabolites were quantified. At the first sampling, 21 days after application, parent imidacloprid was the main compound found in the leaves and its concentration averaged 15·2 μg g^-1 fresh weight. By the 25-leaf stage, 97 days after sowing, the concentration of parent compound in the leaves had fallen to an average of 0·5 μg g^-1; the metabolites and parent compound in the leaves then represented respectively 44·5% and 4·5% of the total applied radioactivity. In the root at 97 days, parent imidacloprid and its metabolites together accounted for only 0·1% of the applied activity, whilst in the soil there was 23% of parent compound and 4% as metabolites. The persistence of both parent imidacloprid and the olefinic metabolite, which has recently been shown to have higher aphicidal activity than the parent imidacloprid, explains the prolonged control of aphids observed with imidacloprid in both glasshouse and field trials. © 1998 SCI.  相似文献   

Efficacy of a starch-iodide swab technique to detect the illegal use of bleach in a Spiny Lobster (Panulirus argus) fishery     

David T. Wilson  Duncan Vaughan  Shaun K. Wilson  Carrie N. Simon  Kathy Lockhart 《Fisheries Research》2008,90(1-3):86-91

The destructive and illegal practice of using chemicals (bleach, dishwashing liquid, gasoline) to catch spiny lobster (Panulirus argus) is thought to be common throughout much of the Bahamian Archipelago. Injection of a chemical irritant into a lobster den will result in either a rapid escape response or a subduing effect, both of which make it easier to capture spiny lobster. We used both laboratory and field trials to determine the efficacy of a starch-iodide swab technique to identify lobsters that had been exposed to bleach solution (NaOCl). All lobsters exposed to bleach tested positive immediately following exposure and for varying periods thereafter. No false positives were detected on control lobsters. The average length of time that bleach remained detectable on the exoskeleton was 6.2 and 9.6 h in the laboratory and field, respectively, with some individuals testing positive 12 h after exposure. The swab technique will provide fishery officers with a powerful tool to reduce or eliminate the illegal use of bleach for harvesting spiny lobster.  相似文献
