Coccidiosis: T-lymphocyte-dependent effects of infection with $\text{Eimeria nieschulzi}$ in rats     

M.Elaine Rose  Patricia Hesketh 《Veterinary immunology and immunopathology》1982,3(5):499-508

The intestinal pathology caused by infection with $\text{Eimeria nieschulzi}$ was investigated and comparisons were made between the effects in athymic nude (rnu/rnu) rats and their heterozygous (rnu/+) litter-mates. Most of the changes noted, i.e. increase in gut weight, partial villous atrophy and increased numbers of mast, goblet and pyroninophilic cells were shown to be largely or wholely thymus dependent. The numbers of intraepithelial lymphocytes were decreased in both groups during the period of study. The peripheral blood leucocyte response was similar in both groups of rats during a primary infection but differed after a challenge inoculum, indicating that the secondary type of response which occurred in the rnu/+ rats was thymus dependent, as is resistance to reinfection.  相似文献   

LARYNGEAL ADENOCARCINOMA IN A DOG     

Susan M.  Newell  DVM  Mary B.  Mahaffey  DVM  MS  Royce E.  Roberts  DVM  MS  Ana  Patricia Garcia  DVM  Anita R.  Stampley  DVM 《Veterinary radiology & ultrasound》1994,35(3):217-220

Laryngeal adenocarcinoma was diagnosed in a 5-year-old golden retriever dog with no history of respiratory or pharyngeal difficulties. Radiographically the basihyoid bone was destroyed by the neoplasm, and extensive soft tissue mineralization ventral to the larynx was also present. Complete surgical resection was not possible due to diffuse involvement of the tongue and larynx. Cobalt-60 teletherapy was used for treatment of the tumor. There was no clinical evidence of tumor regrowth at approximately 12 months post treatment. This is an unusual example of primary laryngeal neoplasia due to the absence of clinical respiratory abnormalities and the aggressive destruction of the basihyoid bone.  相似文献

Intracranial Lesions in Dogs With Hemangiosarcoma   总被引：3，自引：2，他引：1  

David J. Waters DVM    David W. Hayden DVM  PhD  Patricia A. Walter DVM  MS 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1989,3(4):222-230

A retrospective analysis of 85 dogs with hemangiosarcoma (HSA) that underwent complete necropsy, including gross examination of the brain, was conducted. Grossly identifiable intracranial lesions were present in 17 dogs. Twelve of 85 dogs (14.2%) had brain metastases. Four of 85 dogs (4.7%) had hemorrhagic lesions and/or ischemic necrosis without identifiable tumor. One dog had a primary central nervous system tumor. Signs of intracranial disease were present in six of 85 dogs (7.1%) with HSA; four had brain metastases and two had nonneoplastic lesions. Metastases had a propensity for cerebrum and gray matter. Dogs with brain metastases had more widely disseminated disease than dogs without brain metastases (P less than 0.001). Dogs with pulmonary metastases were at greater risk for developing brain metastases than dogs without pulmonary metastases (odds ratio = 8.31). Although thoracic radiography accurately identified ten of 12 dogs (83%) with pulmonary metastases, too few cases were available to assess the applicability/accuracy of thoracic radiography in predicting the presence or absence of brain metastases in dogs with malignancy and signs of intracranial disease.  相似文献

Frequency and severity of tracheal wash hemosiderosis and association with underlying disease in 96 cats: 2002-2003     

DeHeer HL  McManus P 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》2005,34(1):17-22

BACKGROUND: Hemosiderophages may be found in feline tracheal wash specimens in association with various disease conditions, including heart failure, trauma, infection, foreign body migration, lung lobe torsion, pulmonary embolism or infarction, neoplasia, and bleeding diathesis. Based on observations in our laboratory, we hypothesized that tracheal wash specimens from cats with asthma also frequently contain hemosiderophages, even in the absence of other known causes of pulmonary hemorrhage. OBJECTIVES: The purpose of this study was to determine the frequency and severity of hemosiderosis in tracheal wash fluid from cats with various diseases, including asthma. METHODS: Feline tracheal wash fluid specimens submitted for cytologic evaluation between March 2002 and August 2003 were included in the study. One hundred and one specimens from 96 cats were examined with both Wright's-Giemsa and Prussian blue stains. Cats were assigned to 6 disease categories: feline asthma, pneumonia, pulmonary neoplasia, rhinitis, heart disease, and other disorders. Based on the percentage of Prussian blue-positive macrophages, hemosiderosis was categorized as negative (0%), mild (<20%), moderate (21-50%), or marked (>50%). RESULTS: The frequency of tracheal wash hemosiderosis in the study population was 63.5% (61/96); hemosiderosis was mild (29/96, 30.2%), moderate (22/96, 22.9%), or marked (10/96, 10.4%). Hemosiderosis was found in 85.7% (6/7) of cats with rhinitis, 78.6% (11/14) of cats with pulmonary neoplasia, 75.0% (27/36) of cats with asthma, 71.4% (5/7) of cats with primary or concurrent heart disease, 25.0% (5/20) of cats with pneumonia, and 66.7% (12/18) of cats with other disorders. In cats with asthma, hemosiderosis was usually mild to moderate and frequently was accompanied by increased eosinophils. CONCLUSIONS: The results of this study confirm that hemosiderosis is a common finding in tracheal wash specimens collected from cats with diverse disease conditions, including feline asthma syndrome.  相似文献   

Infarctive purpura hemorrhagica in five horses     

Kaese HJ  Valberg SJ  Hayden DW  Wilson JH  Charlton P  Ames TR  Al-Ghamdi GM 《Journal of the American Veterinary Medical Association》2005,226(11):1893-8, 1845

Five horses were examined because of signs of muscle stiffness, colic, or both. All 5 had been exposed to Streptococcus equi within 3 weeks prior to examination or had high serum titers of antibodies against the M protein of S equi. Horses had signs of unrelenting colic-like pain and focal areas of muscle swelling. Four horses were euthanatized. The fifth responded to treatment with penicillin and dexamethasone; after 3 weeks of treatment with dexamethasone, prednisolone was administered for an additional 10 weeks. Common hematologic and serum biochemical abnormalities included neutrophilia with a left shift and toxic changes, hyperproteinemia, hypoalbuminemia, and high serum creatine kinase and aspartate transferase activities. Necropsy revealed extensive infarction of the skeletal musculature, skin, gastrointestinal tract, pancreas, and lungs. Histologic lesions included leukocytoclastic vasculitis in numerous tissues and acute coagulative necrosis resembling infarction. These horses appeared to have a severe form of purpura hemorrhagica resembling Henoch-Sch?nlein purpura in humans and characterized by infarction of skeletal muscles. Early recognition of focal muscle swelling, abdominal discomfort, neutrophilia, hypoalbuminemia, and high serum creatine kinase activity combined with antimicrobial and corticosteroid treatment may enhance the likelihood of a successful outcome.  相似文献
