A microsporidian infection in sheepshead minnow (Cyprinodon variegatus)     

S. K. MAJEED  M. DOUGLAS†  D. W. JOLLY 《The Journal of small animal practice》1985,26(2):91-96

Approximately 500 fish were delivered to the Department of Fish Toxicology for routine experiments. Post-mortem examination of 19 fish (10 males and 9 females) revealed the presence of greyish white cysts in the abdominal cavity, loosely attached to the viscera. Apparently, 50 percent of the total 500 fish were affected, none of which showed clinical abnormality. Pathological results are described and discussed.  相似文献   

Outcomes of thoracic surgery in dogs and cats   总被引：1，自引：0，他引：1  

CR BELLENGER #  GB HUNT †  SE GOLDSMID  MRB PEARSON 《Australian veterinary journal》1996,74(1):25-30

Summary: Records of 146 dogs and 41 cats that underwent thoracic surgery at The University of Sydney Veterinary Teaching Hospital were reviewed for age, sex, breed, disease, operation date, periods of pre- and post-operative hospitalisation, use of surgical drains and outcome. Animals were assigned to 16 disease categories, the most common being patent ductus arteriosus, traumatic diaphragmatic hernia and oesophageal foreign body in dogs and traumatic diaphragmatic hernia in cats. Differences were observed between disease categories in all the criteria examined. There were almost equal numbers of male (72) and female (74) dogs, the median (range) age was 2.0 (0.2 to 14.0) years, the median pre-operative stay was 1 (0 to 14) days, the median post-operative stay was 4 (0 to 28) days and the overall survival to discharge rate was 78%.
There were 24 male and 15 female cats (sex not recorded in 2 cats). The median (range) age was 3 (0.1 to 12) years, pre-operative stay 1 (0 to 6) days, post-operative stay 5 (0 to 15) days and the overall survival to discharge rate was 85%. Causes of post-operative deaths among animals in the most common categories are recorded and discussed.  相似文献   

Association of phytoplasmas with the decline of European hazel in southern Italy   总被引：1，自引：0，他引：1  

C. MARCONE  A. RAGOZZINO  E. SE EMÜLLER 《Plant pathology》1996,45(5):857-863

In the Campania region of southern ltaly. commercial orchards of European hazel ( Corylus avellana ) are severely affected by yellowing and decline. To determine whether phytoplasmas are associated with the disorder, stem samples from diseased trees were examined using polymerase chain reaction assays. No visible products were obtained by amplification of sample DNA with universal and group-specific phytoplasma primers. However, when the products obtained with universal primers were re-amplified with nested primers that were specific for the fruit tree phytoplasmas of the apple proliferation group, most samples tested positively. Restriction site analysis revealed that the trees were infected with the apple proliferation, pear decline, and European stone fruit yellows phytoplasmas in about the same proportion. Some of the trees were doubly infected with one of the fruit tree phytoplasmas and the aster yellows agent. Most of the infected trees were also identified by hybridization of the products obtained in the initial amplification with suitable oligonucleotide probes.  相似文献   

From cell to cageside: autonomic influences on cardiac rhythms in the dog     

N. S. MoïSE 《The Journal of small animal practice》1998,39(10):460-468

The autonomic nervous system is pivotal in the characteristics of normal and abnormal cardiac rhythms. Some of the unique features (pronounced sinus arrhythmia and wandering pacemaker) of the canine electrocardiogram can be explained by the influence of parasympathetic tone. Perturbations that enhance the sympathetic nervous system can also potentiate arrhythmias, or counteract antiarrhythmic action. Moreover, disorders of the innervation to the heart may actually cause some life-threatening arrhythmias. This article reviews the interactions of the autonomic nervous system and cardiac rhythms as they pertain to the normal dog, as well as to specific arrhythmias in the boxer and German shepherd dog. Emphasis is placed on relating information from electrophysiological investigations to the clinical arena, thus demonstrating the value of linking the basic and clinical sciences as one medicine: knowledge from cell to cageside.  相似文献

The dose-related effects of phenylbutazone and a methylprednisolone acetate formulation (Depo-Medrol®) on cultured explants of equine carpal articular cartilage     

W.T. JOLLY  T. WHITTEM  A.C. JOLLY†  E.C FIRTH 《Journal of veterinary pharmacology and therapeutics》1995,18(6):429-437

The dose-related effects of phenylbutazone and Depo-Medrol® on chondrocyte viability and chondrocyte-mediated synthesis and depletion of proteoglycans were investigated using cultured explants of equine middle carpal joint articular cartilage. Explants from 12 horses (941 × 3 mm diameter) were cultured for a total of 5 days, which included 3 days' exposure to either phenylbutazone (0, 2, 20, 200 or 2000 μg/mL) or Depo-Medrol (0, 20, 200 or 2000 μg/mL). For each explant, amino sugar content was used as a measure of proteoglycan content, ³⁵S incorporation as a measure of the rate of proteoglycan synthesis and the number of pyknotic nuclei as a measure of cell death. During culture, control explants remained metabolically active and viable but suffered a net loss of proteoglycans. Proteoglycan loss was reduced by the presence of either phenylbutazone or Depo-Medrol. This effect was significant at clinically relevant concentrations of phenylbutazone (2–20 μg/mL), but not Depo-Medrol (20–200 μg/mL). Depo-Medrol caused a dose-dependent suppression of proteoglycan synthesis at all concentrations, but chondrocyte viability was affected only at the 2000 μg/mL dose. Phenylbutazone affected proteoglycan synthesis and cell viability only at the 2000 μg/mL concentration. At all concentrations, the anticatabolic effects of each drug influenced the proteoglycan content of the explants far more than did any antianabolic or cytotoxic drug effect. The results suggest that the therapeutic potential of both phenylbutazone and Depo-Medrol may not be restricted to their anti-inflammatory effects on the soft tissues of the joint.  相似文献
