Differential alterations in ultrastructural morphology of chicken heterophils and lymphocytes induced by corticosterone and lipopolysaccharide   总被引：1，自引：1，他引：0

Birds are continuously confronted by a large number of stressors, including pathogens. Despite their variety, all stressors induce an elevation in plasma corticosterone concentration, and consequently increase heterophil to leukocyte (H/L) ratio. In order to evaluate and differentiate effects of endocrine (non-bacterial) and bacterial stress on the proportions and ultrastructural characteristics of chicken leukocytes, a series of experiments were conducted with seven-week old chickens exposed either to dietary corticosterone or to intravenous (i.v.)-injected lipopolysaccharide (LPS). Samples were taken for haematological, endocrine, and electron microscopy examination. Administration of corticosterone and LPS significantly elevated plasma corticosterone concentrations and increased H/L ratios. Electron microscopy observations indicated changes in heterophil size, shape, and granulation, and lymphocyte cytoplasmic characteristics. Immature heterophils were observed in the peripheral blood, suggesting that corticosterone and LPS both stimulate an earlier release of heterophils from bone marrow and enhance their influx into blood circulation. The LPS induced a degenerative morphology and the destruction of lymphocytes, whereas corticosterone appeared to stimulate their redistribution rather than destruction. The results indicate that exposure to corticosterone or LPS similarly increase H/L ratios, but differentially alter the ultrastructure of heterophils and lymphocytes. Elucidation of the mechanisms that cause such changes may play an important role in distinguishing between a nonimmune and immune stress challenge at the molecular level.  相似文献

Equine amnionitis and fetal loss: The case definition for an unrecognised cause of abortion in mares     

KH Todhunter  NR Perkins  RM Wylie  C Chicken  AJ Blishen  DJ Racklyeft  G Muscatello  MC Wilson  PL Adams  JR Gilkerson  WL Bryden  AP Begg 《Australian veterinary journal》2009,87(1-2):35-38

A series of abortions occurred in mares in New South Wales during 2004 that involved similar and unusual findings on post mortem examination of aborted fetuses and fetal membranes. The term Equine Amnionitis and Fetal Loss (EAFL) was developed to describe the condition. This form of abortion had not been previously recognised in Australia. The pathology alone is not specific for EAFL and diagnosis requires demonstration of a combination of certain pathological and bacteriological features. The purpose of this paper is to describe patterns considered consistent with EAFL cases as a working case definition for use by veterinarians and veterinary pathologists in identifying future cases of EAFL. More detailed papers are in preparation to fully describe the epidemiological, histopathological, and microbiological aspects of EAFL.  相似文献

Use of an axial pattern flap and nictitans to reconstruct medial eyelids and canthus in a dog     

Susan Jacobi  Bryden J. Stanley  Simon Petersen-Jones  Nikolaos Dervisis  Pedro A. Dominguez 《Veterinary ophthalmology》2008,11(6):395-400

A 10-year-old male neutered Boxer presented with recurrence of a mast cell tumor at the right medial canthal area. Following excision including 2 cm margins, the medial one-half of the upper and lower eyelids and the medial canthus were reconstructed using an axial pattern flap based on the cutaneous branch of the superficial temporal artery. The bulbar conjunctiva of the nictitans was preserved and sutured to the medial flap edge, thus creating a conjunctival lining to the deep aspect of the flap, protecting corneal epithelium. This is a valuable surgical technique for closing a large skin defect and reconstructing the medial eyelids, thus preserving the globe.  相似文献   

Clinical, histopathological and immunological characteristics of exfoliative cutaneous lupus erythematosus in 25 German short-haired pointers     

Bryden SL  White SD  Dunston SM  Burrows AK  Olivry T 《Veterinary dermatology》2005,16(4):239-252

Clinical, histopathological and immunological features of exfoliative cutaneous lupus erythematosus, an uncommon generalized exfoliative dermatitis occurring exclusively in German short-haired pointers, were characterized in 25 dogs. The disease affects young adult dogs and its familial incidence strongly suggests a hereditary origin. Lesions were characterized by scaling and alopecia affecting 100 (25/25) and 76% (19/25) of dogs, respectively. Follicular casts were present in 28% (7/25) of dogs. The muzzle, pinnae and dorsum were typically affected. Generalized skin lesions were described in 52% (13/25) of dogs. Systemic signs of pain and lameness affected several dogs. Anaemia and thrombocytopenia were detected in several dogs with a more severe clinical phenotype. The most common histopathological features were hyperkeratosis and a lymphocytic interface dermatitis. Direct immunostaining revealed IgG deposition in the epidermal and follicular basement membrane of 100 (19/19) and 41% (7/17) of dogs, respectively. Circulating antifollicular and antisebaceous gland IgG antibodies were demonstrated by indirect immunostaining in 57% (4/7) of dogs. This disease usually responds poorly to immunosuppressive therapy and it has a guarded prognosis. Where outcome was recorded, 85% (10/12) of dogs were euthanased due to either a failure to respond to, or complications associated with, immunomodulatory therapy. Two affected dogs are in remission and maintained on immunomodulatory dosages of prednisolone. This study demonstrates the existence of a cellular and humoral immune response directed against the epidermal basement membrane of dogs with exfoliative cutaneous lupus erythematosus. Additional studies are required to further characterize the immunological pathogenesis of this disease.  相似文献   

Efficacy of cyclosporin in the treatment of atopic dermatitis in dogs--combined results from two veterinary dermatology referral centres   总被引：1，自引：0，他引：1

OBJECTIVE: To evaluate the efficacy of cyclosporin in controlling the clinical signs associated with atopic dermatitis in dogs under Australian field conditions. DESIGN: A multicentre prospective clinical investigation of the use of cyclosporin in 41 dogs with atopic dermatitis. PROCEDURE: Dogs were treated with cyclosporin (5 mg/kg orally once daily with food) for 6 weeks. Four clinical parameters of severity of atopic dermatitis were measured on Day 0 and on Day 42 using a 0 to 4 scoring system. Individual variables were then combined to form a Global Score. Both client and clinician observed pruritus scores were combined to form a Pruritus Score. Pre- and post-treatment scores were statistically analysed. The difference in results between the two investigators was also recorded and analysed. RESULTS: All dogs showed a marked reduction in pruritus and erythema during the 6-week treatment period. All dogs showed a significant (P < 0.001) improvement in clinical lesion scores and Global Score (P < 0.001). The mean percentage improvement in Global Score from Day 0 to Day 42 was 83.9%. The mean percentage improvement in Pruritus Score from Day 0 to Day 42 was 83%. The medication was well tolerated. Side effects such as vomiting, diarrhoea and soft stools were observed in four dogs. Another four dogs developed bacterial pyoderma during the trial period. There was no significant difference in results between the two centres. CONCLUSION: Cyclosporin was well tolerated and efficacious in the symptomatic treatment of atopic dermatitis in dogs attending two veterinary dermatology referral centres in Australia, under Australian field conditions, when administered at 5 mg/kg/day for 6 weeks.  相似文献
