THE ROLE OF ULTRASOUND IN THE ASSESSMENT OF LARYNGEAL PARALYSIS IN THE DOG     

Heike  Rudorf  DMV  Frances J.  Barr  MB  PhD  J. Geoffrey  Lane  BVM 《Veterinary radiology & ultrasound》2001,42(4):338-343

Forty dogs with clinical signs suggestive of upper respiratory tract disease underwent echolaryngography and laryngoscopy. Laryngoscopy was used as the definitive technique to diagnose laryngeal paralysis. The ultrasound investigation accurately indicated the presence of the paralysis and confirmed the uni- or bilateral nature of the disorder. Findings indicative of laryngeal paralysis included asymmetry or absence of motion of the cuneiform processes (30/30), abnormal arytenoid movement (16/30), paradoxical movement (9/30), caudal displacement of the larynx (2/30) and laryngeal collapse (1/30). Thirty dogs were found to be afflicted with laryngeal paralysis and ten had normal laryngeal motility.  相似文献

Intact Parathyroid Hormone Assay and Total Calcium Concentration in the Diagnosis of Disorders of Calcium Metabolism in Dogs   总被引：1，自引：0，他引：1  

A. G. Torrance MA    Vet MB  R. Nachreiner DVM  PhD 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1989,3(2):86-89

Serum samples from eight dogs with primary hyperparathyroidism, seven dogs with hypercalcemic lymphosarcoma (hypercalcemia of malignancy), and four dogs with primary hypoparathyroidism were submitted to the Animal Health Diagnostic Laboratory at Michigan State University for intact parathyroid hormone (PTH) assay. When compared with the adjusted total serum calcium concentration, the intact PTH concentration was consistent with the correct diagnosis in all cases. Two dogs with hypercalcemic lymphosarcoma were mildly azotemic. In both of these cases the intact PTH concentration was consistent with hypercalcemia of malignancy despite the presence of azotemia. These data support a significant role for intact serum PTH assay in the differential diagnosis of disorders of calcium metabolism.  相似文献   

Ovine dermatophilosis in young sheep associated with the grazing of Brassica spp. crops     

Allworth MB  West DM  Bruère AN 《New Zealand veterinary journal》1985,33(12):210-212

The occurrence of dermatophilosis in five month old lambs associated with the grazing of Brassica spp. crops is reported on four farms. The prevalence of the disease varied from 3% to 45% within affected flocks. An additional finding was the occurrence of nervous signs in a small number of more severely affected lambs, characterised by a sudden lowering of the hindquarters. The association between dermatophilosis and the grazing of Brassica spp. crops is discussed.  相似文献

Ultrasonographic Appearance of Dandy Walker-Like Syndrome in a Boston Terrier     

Clarissa Noureddine  DVM  MS    Rebecca Harder  DVM    Natasha J. Olby  Vet. MB  PhD    Kathy Spaulding  DVM    Talmage Brown  DVM  PhD 《Veterinary radiology & ultrasound》2004,45(4):336-339

Congenital cerebellar disorders can be caused by in utero or neonatal infections, genetic aberrations causing malformations, and neurodegenerative processes. Most congenital cerebellar disorders are diagnosed definitively with histopathology. However, antemortem diagnosis of cerebellar malformations can be made by imaging the brain. This paper describes the antemortem appearance of a congenital cerebellar malformation in a Boston Terrier puppy on ultrasound images. This appearance was compared with the postmortem findings that were comparable to Dandy Walker Syndrome in humans. A previous report of this syndrome in Boston Terriers suggests the problem may be inherited in this breed.  相似文献   

A survey on bloat in southern Australian beef production systems     

MB Allworth  M McQuillan  SR McGrath  CS Wilson  M Hernandez-Jover 《Australian veterinary journal》2023,101(3):121-126

Frothy bloat, associated predominantly with grazing legume-based pastures, is considered the second most costly disease in beef cattle in southern Australia, costing $84.4 M annually. It frequently results in the sudden death of cattle. In response to concerns from cattle producers, an online survey was conducted in southern Australia in late 2020 to determine the impact of bloat, identify risk factors and determine the efficacy of current preventive measures. For 217 responses, over two-thirds (70%) of producers reported bloat occurring in the previous 12 months, with estimated morbidity and mortality rates of 3.7% and 5.0% respectively. Bloat was associated with clover or clover-dominant paddocks (79%) and was not associated with grass or grass-dominant pastures or low clover pastures (92%) nor grazing crops (27%). For bloat that occurred in the past 12 months, cattle were very commonly grazing on clover or clover-dominant paddocks (90%) and occasionally lucerne-dominated paddocks (7%). Two-thirds of producers reported having preventive measures in place when losses occurred. Bayesian Network analysis confirmed that grazing clover-based pastures for more than 7 days, yearling cattle and the months of July–September were the main risk factors for bloat occurrence, with pasture type (clover) being the most important. Conversely, no clear relationship between weather conditions and bloat occurrence was evident. This survey highlights the known risk of clover-based pastures for causing bloat in cattle, and that losses occur in many cases despite preventive measures being used. This suggests that current methods for preventing bloat in cattle are suboptimal.  相似文献   

Effect of Recombinant Bovine Somatotropin on Plasma Concentrations of Insulin‐like Growth Factor I,Insulin and Membrane Integrity of Bull Spermatozoa     

MB Vieira  I Bianchi  EM Madeira  VFB Roll  CA Oliveira  P Viau  I Pivato  NC Severo  FAB Del Pino  A Schneider  MN Corrêa 《Reproduction in domestic animals》2010,45(6):1110-1113

This study aimed to evaluate the effect of the exogenous recombinant bovine somatotropin (rbST) on plasma concentrations of insulin‐like growth factor I (IGF‐I), insulin and semen quality of bulls. Twenty bulls (Aberdeen Angus and Brangus) were divided by breed into two groups. Placebo group was injected with NaCl 0.9% (s.c.) and treatment group with rbST (s.c., 500 mg) at days 0 and 14 of the experiment. Immediately after semen collection, blood samples were taken on days 0, 14, 28, 42 and 56 of the experiment. Semen was also collected on day 70 of the experiment. Evaluation of sperm motility was performed at pre‐freezing and post‐thawing stage, whereas assessment of sperm membrane integrity was performed after freezing and thawing. Analysis of data revealed that the effect of treatment and treatment‐by‐collection day on plasma concentrations of IGF‐I and insulin was not significant. However, mean plasma concentrations of IGF‐I and insulin were affected (p < 0.0001) by days of blood sampling. Effect of treatment and treatment‐by‐collection day on motility of spermatozoa was similar (p > 0.05) at pre‐freezing and post‐thawing stage. Intactness of plasmalemma and tail membrane of spermatozoa at post‐thawing stage was higher (p < 0.05) in rbST‐treated group than in control. In conclusion, rbST did not affect plasma concentrations of IGF‐I and insulin, however, it did improve post‐thaw sperm membrane integrity.  相似文献

DOPPLER MEASUREMENT OF HEPATIC ARTERIAL FLOW IN DOGS: TECHNIQUE AND PRELIMINARY FINDINGS     

C.R. Lamb  MA  Vet MB  C.A. Burton  BVet Med  C.H. Carlisle  MVSc  DVR FACVS 《Veterinary radiology & ultrasound》1999,40(1):77-81

The common hepatic artery in 10 healthy adult beagles, 20 healthy pups (13 Deerhounds and seven Irish Wolfhounds), and seven dogs with either a congenital or acquired hepatic disorder was examined by duplex-Doppler ultrasonography. Peak systolic velocity (Vs), resistive index (RI), pulse rate, angle of insonation, and sample volume depth were recorded. Measurements in Beagles were made after a 24 h fast and repeated 2 h after feeding. The mean Vs and RI in fasted Beagles were 1.5 m/s (range 1.1-2.3 m/s) and 0.68 (range 0.62-0.74), respectively. Postprandially, there were no significant differences in any of these variables. Mean Vs and RI were lower in pups: 1.0 m/s (range 0.8-1.3 m/s) and 0.59 (range 0.46-0.65), respectively (P < .001). Two dogs with congenital arterioportal fistula had higher mean Vs (P < .001) and lower mean RI (P < .05) than normal pups. No significant differences were detected between normal Beagles, three dogs with portal vein thrombosis, and two dogs with acquired hepatic insufficiency. Differences in measured hepatic blood flow in dogs of different age or breed will complicate diagnostic use of hepatic arterial Doppler measurements.  相似文献
