Squamous Cell Carcinoma Arising in Chronic Discoid Lupus Erythematosus Nasal Lesions in Two German Shepherd Dogs     

DANNY W. SCOTT  WILLIAM H. MILLER JR. 《Veterinary dermatology》1995,6(2):99-104

Résumé— Un épithélioma spinocellulaire s'est développé sur des lésions chroniques incontrôlées de lupus erythémateux discoïde chez deux chiens bergers allemands. Les chiens n'avaient reçu ni traitement ni photoprotection pour leurs lésions de lupus discoïde durant les 4 à 6 ans précédant l'apparition clinique d'épithéliomas spinocellulaires.

Abstract— Squamous cell carcinoma developed in the chronic, uncontrolled nasal lesions of discoid lupus erythematosus in two German Shepherd Dogs. The dogs had received no treatment nor photoprotection for their discoid lupus erythematosus for 4–6 years prior to the clinical onset of squamous cell carcinoma.  相似文献

Gradual Occlusion of Extrahepatic Portosystemic Shunts in Dogs and Cats Using the Ameroid Constrictor     

JAMES C. VOGT DVM    D.J. KRAHWINKEL JR  DVM  MS  Dipiomate ACVS  RONALD M. BRIGHT DVM  MS  Dipiomate ACVS    GREGORY B. DANIEL DVM  MS  Dipiomate ACVR    ROBERT L. TOAL DVM  MS  Dipiomate ACVR  BARTON ROHRBACH DVM  MS 《Veterinary surgery : VS》1996,25(6):495-502

Gradual occlusion of the splenic vein, using a specialized device (ameroid constrictor), was evaluated experimentally in three normal beagle dogs. Splenoportograms were used to verify that total occlusion of the splenic vein had occurred in all dogs within 4 to 5 weeks after application of the device. The ameroid constrictor (AC) was also evaluated as a method of gradual vascular occlusion in 12 dogs and two cats with single, extrahepatic, portosystemic shunts (PSS). Serum bile acid (SBA) concentrations were measured and portal scintigraphy (PS) was performed on all 14 animals preoperatively and 10, 20, 30, and 60 days postoperatively. Two dogs (14%) died from portal hypertension in the early postoperative period. One dog and one cat developed multiple acquired PSS, confirmed by mesenteric portography 90 days after the operation. Portal scintigraphy confirmed total occlusion of the primary shunt in the other 10 animals. Shunt fractions (SF), as measured by PS on postoperative days 30 and 60, declined significantly from preoperative values. Significant decreases were noted between preoperative and postoperative values for preprandial SBA on postoperative day 60 and for postprandial SBA on postoperative day 30. SBA concentrations did not correlate with SF. Based on this study, gradual vascular occlusion using the AC is recommended as a method for treatment of single, extrahepatic, PSS.  相似文献   

Effects of general anesthesia on myoelectric activity of the intestine in horses.   总被引：2，自引：0，他引：2  

G D Lester  J R Bolton  L K Cullen  S M Thurgate 《American journal of veterinary research》1992,53(9):1553-1557

Myoelectric activity was monitored from the terminal ileum, cecum, and colonic pelvic flexure by use of AgpAgCl bipolar electrodes in 4 adult horses before, during, and after general anesthesia. Horses were anesthetized by way of 3 commonly used regimens, including xylazine (1.1 mg/kg of body weight) and ketamine hydrochloride (2.2 mg/kg); thiopental sodium (7.7 mg/kg), followed by halothane vaporized in oxygen; and thiopental sodium (2.5 g) in guaifenesin (100 mg/ml) solution given to effect, followed by halothane in oxygen. All 3 anesthetic regimens decreased intestinal spike-burst activity in the areas monitored. The slowest return to preanesthetic myoelectric activity was observed after xylazine and ketamine administration. After both of the barbiturate/halothane anesthetic regimens, there was a rebound increase in spike-burst frequency, without alteration in the proportion of propagative myoelectric events. All 3 anesthetic regimens appeared to reset the timing of the small and large intestinal migrating myoelectric complexes. By 9 hours after recovery from anesthesia, the effects of anesthesia, irrespective of regimen, had disappeared. Although anesthesia significantly (P less than 0.05) altered intestinal myoelectric activity, no particular anesthetic regimen had a prolonged effect. Results of our study indicate that the particular chosen regimen of general anesthesia is unimportant in development of motility disturbances in horses after anesthesia.  相似文献

Circulating growth hormone and prolactin concentrations in turkeys and chickens infected with histomonas meleagridis     

A. Chadwick  S. Harvey  C. G. Scanes  N. J. Bolton  S. E. Hebditgh  D. L. Lee 《British poultry science》1980,21(2):89-94

1. Histomonas meleagridis was inoculated into young chickens and turkeys and the effect of the infection (blackhead) on circulating growth hormone (GH) and prolactin concentrations determined.

2. During the course of the infection in turkeys there was a marked increase in plasma GH concentration which correlated with the severity of the disease, as judged by liver and caecal characteristics. The infection was less severe in chickens and no correlation between plasma GH and the degree of infection was observed.

3. The concentration of plasma prolactin was increased in the chicken, but not in the turkey, during the invasive period of infection.  相似文献

Antimicrobial labelling in Australia: a threat to antimicrobial stewardship?          下载免费PDF全文

Antimicrobial resistance is a public health emergency, placing veterinary antimicrobial use under growing scrutiny. Antimicrobial stewardship, through appropriate use of antimicrobials, is a response to this threat. The need for antimicrobial stewardship in Australian veterinary practices has had limited investigation. A 2016 survey undertaken to investigate antimicrobial usage patterns by Australian veterinarians found that antimicrobial dose rates were varied and often inappropriate. Doses of procaine penicillin in horses and cattle were often low, with 68% and 90% of respondents, respectively, reporting doses that were unlikely to result in plasma concentrations above minimum inhibitory concentrations for common equine and bovine pathogens. Frequency of penicillin administration was also often inappropriate. Gentamicin doses in horses were largely appropriate (89% of dose rates appropriate), but 9% of respondents reported twice daily dosing. Amoxycillin and amoxycillin‐clavulanate were administered at the appropriate doses, or above, to dogs and cats by 54% and 70% of respondents, respectively. Here, we explore the potential reasons for inappropriate antimicrobial dose regimens and report that antimicrobial labels often recommend incorrect dose rates and thus may be contributing to poor prescribing practices. Changes to legislation are needed to ensure that antimicrobial drug labels are regularly updated to reflect the dose needed to effectively and safely treat common veterinary pathogens. This will be especially true if changes in legislation restrict antimicrobial use by veterinarians to the uses and doses specified on the label, thus hampering the current momentum towards improved antimicrobial stewardship.  相似文献
