Ultrasonography and MRI have become valuable tools for imaging of tendon injuries. The current study examines the histopathologic basis for the imaging abnormalities. Five injured equine forelimbs and two normal contralateral limbs were studied with high resolution real time ultrasound and MRI. Histologic sections were made and correlated with the diagnostic images. All lesions were readily seen by both modalities. Lesions characterized by hemorrhage, edma, and cellular infiltration were sonolucent on ultrasound and bright on MRI images. MRI returned to normal as fibrogenesis ensued. Ultrasound images remained abnormal until fibrillar reallgnment occured with completion of the healing process. High resolution real time ultrasound and MRI both accurately reflect the tissue abnormalities in acute tendon injuries. The injured horse does appear to be an effective model for correlative imaging studies of tendon injuries.  相似文献   

Arthropathy associated with Brucella abortus strain 19 vaccination in cattle. II. Experimental studies     

M J Corbel  F A Stuart  R A Brewer  M Jeffrey  R Bradley 《The British veterinary journal》1989,145(4):347-355

Attempts to reproduce in calves the arthropathy associated with Brucella abortus strain 19 (S19) vaccination by direct intra-articular injection of S19 or virulent Brucella cells were unsuccessful. Intra-articular injection of rabbits and a calf with immune complexes isolated from the synovial fluid of a field case produced clinical and histological signs of arthropathy accompanied by the development of rheumatoid factor.  相似文献   

Chylothorax associated with cryptococcal mediastinal granuloma in a cat     

Meadows RL  MacWilliams PS  Dzata G  Meinen J 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1993,22(4):109-116

A 10-year-old neutered female cat had chylothorax, precaval syndrome, and a mediastinal granuloma resulting from infection with Cryptococcus neoformans. Diagnosis of a chylous effusion was made by cytologic examination of pleural fluid and by finding higher triglyceride levels in the effusion than in serum (825 vs. 64 mg/dl, respectively). Postmortem examination revealed cryptococcal organisms in the mediastinal granuloma, lungs, cerebral meninges, and connective tissues adjacent to the thyroid gland. Chylous effusion in a cat associated with cryptococcosis has not been reported previously. Cryptococcosis should be included in the differential diagnosis in chylous effusions in cats.  相似文献   

Bilateral phacofragmentation in a New Zealand fur seal (Arctocephalus forsteri).     

Julie A Barnes  Jeffrey S Smith 《Journal of zoo and wildlife medicine》2004,35(1):110-112

Ophthalmic examination under anesthesia of a 5-yr-old, captive, male New Zealand fur seal (Arctocephalus forsteri) with reduced visual capacity revealed bilateral cataracts. Surgical extraction of the lenses was performed by phacofragmentation. Preoperative mydriasis was unsuccessful using common topical mydriatic agents. Intraoperative intracameral epinephrine 1:10,000 produced minimal pupillary dilation, but excellent dilation was achieved with intracameral epinephrine at 1:1,000. Postoperative uveitis was controlled with oral prednisolone. Postoperative complications included generalized corneal edema persisting for approximately 1 wk and corneal ulceration caused by the lateral canthotomy sutures. Vision was restored in both eyes.  相似文献   

Expression of the tobacco β-1,3-glucanase gene, PR-2d, following induction of SAR with Peronospora tabacina     

Deanna L. Funnell  Christopher B. Lawrence  Jeffrey F. Pedersen  Christopher L. Schardl 《Physiological and Molecular Plant Pathology》2004,65(6):285-296

Systemic acquired resistance (SAR) is induced following inoculation of Peronospora tabacina sporangia into the stems of Nicotiana tabacum plants highly susceptible to the pathogen. Previous results have shown that accumulation of acidic β-1,3-glucanases (PR-2's) following induction of SAR by P. tabacina may contribute to resistance to P. tabacina. We showed that up-regulation of the PR-2 gene, PR-2d, following stem inoculation with P. tabacina, is associated with SAR. Studies using plants transformed with GUS constructs containing the full length promoter from PR-2d or promoter deletions, provided evidence that a previously characterized regulatory element that is involved in response to salicylic acid (SA), may be involved in regulation of PR-2d following induction of SAR with P. tabacina. This work provides evidence that regulation of PR-2 genes during P. tabacina-induced SAR may be similar to regulation of these genes during infection of N-gene tobacco by TMV or following exogenous application of SA, and provides further support for the role of SA in regulation of genes during P. tabacina-induced SAR.  相似文献   

Characterization and PCR-based Typing of Xanthomonas campestris pv. vesicatoria from Peppers and Tomatoes in Serbia     

Aleksa Obradovic  Athanassios Mavridis  Klaus Rudolph  Jaap D. Janse  Momcilo Arsenijevic  Jeffrey B. Jones  Gerald V. Minsavage  Jaw-Fen Wang 《European journal of plant pathology / European Foundation for Plant Pathology》2004,110(3):285-292

During the last two decades bacterial strains associated with necrotic leaf spots of pepper and tomato fruit spots were collected in Serbia. Twenty-eight strains isolated from pepper and six from tomato were characterized. A study of their physiological and pathological characteristics, and fatty acid composition analysis revealed that all of the strains belong to Xanthomonas campestris pv. vesicatoria. Being non-amylolytic and non-pectolytic, pathogenic on pepper but not on tomato, containing lower amounts of fatty acid 15 : 0 ante–iso, the pepper strains were designated as members of the A group of X. campestris pv. vesicatoria. However, the tomato strains hydrolyzed starch and pectate, caused compatible reactions on tomato but not on pepper, had higher percent of 15 : 0 ante–iso fatty acid, and were classified into B phenotypic group and identified as X. vesicatoria. PCR primers were developed which amplified conserved DNA regions related to the hrp genes of different strains of X. campestris pv. vesicatoria associated with pepper and tomato. Restriction analysis of the PCR product resulted in different patterns and enabled grouping of the strains into four groups. When xanthomonads isolated from pepper and tomato in Serbia were analyzed, they clustered into two groups corresponding to the grouping based on their physiological and pathological characteristics. According to the reaction of pepper and tomato differential varieties, the strains from pepper belong to races P7 and P8 and tomato strains belong to the race T2. All strains were sensitive to copper and streptomycin. Advantages and disadvantages of various bacterial spot management practices are discussed.  相似文献

Conjunctival habronemiasis in a square‐lipped rhinoceros (Ceratotherium simum)          下载免费PDF全文

Igal H. Horowitz  Richard R. Dubielzig  Ana‐Maria Botero‐Anug  Araceli Lucio‐Forster  Dwight D. Bowman  Ariella B. Rosenzweig  Shahar Frenkel  Ron Ofri 《Veterinary ophthalmology》2016,19(2):161-166

A captive female square‐lipped rhinoceros born in 1993 had been showing intermittent signs of bilateral conjunctivitis and conjunctival proliferation since 1998. Periodic improvement was noted, especially in winter, but overall the condition had deteriorated over the years. Treatment with various topical, intralesional, and systemic antibiotics and glucocorticosteroids was largely ineffective, as were repeated dewormings. No primary cause for these lesions was found in biopsies taken in 2000 and 2006, although a severe infiltrate of numerous eosinophils was observed in the latter. As the condition worsened, secondary corneal changes were noted, and eventually vision was lost due to proliferative conjunctival tissue. Aggressive resection of the proliferating tissue in 2013 restored vision and submitted biopsies yielded a diagnosis of severe allergic conjunctivitis, eosinophilic granuloma, and habronematid (Habronema or Draschia) larval infection. As no other rhinoceros in the herd was affected, including two calves born to the patient who were in close contact with their mother, it was concluded the presentation was most likely due to a hypersensitivity reaction to the dead or dying larvae. Fly repellent is now regularly applied around the eye of this rhinoceros, and a protective face mask has been fitted. Ongoing periodic relapses are treated with oral ivermectin, topical antibiotics, and steroids.  相似文献
