OBJECTIVE To determine risk, clinical features, and treatment responses for gallbladder disorders in Shetland Sheepdogs. DESIGN Retrospective case-control study. ANIMALS 38 Shetland Sheepdogs with gallbladder disease. PROCEDURES Medical records were reviewed for signalment, history, physical findings, laboratory results, imaging features, coexistent(More)
Long-term follow-up information pertaining to 162 dogs with appendicular osteosarcoma treated by amputation alone was collected from 17 veterinary institutions. The majority (72.5%) of dogs died or were euthanatized because of problems documented to be related to metastases. The first clinically apparent sites of metastasis were the lungs (60.8% of total),(More)
BACKGROUND Pet dogs and men share a vulnerability for the development of prostate carcinoma. The purpose of this study was to further characterize the clinical and pathologic features of spontaneous canine prostate carcinoma. METHODS A multiinstitutional, retrospective study was conducted using 76 dogs with prostate carcinoma that underwent postmortem(More)
A protein that binds the calcium-channel antagonist verapamil has been partially purified from maize (Zea mays) coleoptile membranes. The protein was solubilized with the detergent CHAPS ([ 3-(3-cholamidopropyl)dimethylammonio]propane-1-sulphonate) and purified by a combination of ion-exchange, gel-filtration and hydrophobic-interaction chromatography. This(More)
A 10-year-old female dog with endocrine abnormalities and abdominal distention was found to have a functional ovarian tumor. Exploratory laparotomy and histologic examination of excised specimens led to a diagnosis of granulosa cell tumor with widespread metastasis. The prognosis appeared grave because tumor tissue remained on the liver and parietal(More)
The presence of estrogen receptor in 67 canine mammary lesions was correlated with pathological features of the disease. All tissue specimens were analyzed for estrogen receptor content by a sucrose gradient ultracentrifugation method previously used in analyzing human breast cancer cytosols. Pathological features of the tissues were assessed by a(More)
The livers of 16 woodchucks with naturally acquired chronic infection with woodchuck hepatitis virus were examined both grossly and histologically in 14 biopsy specimens and seven necropsy specimens. Fifteen woodchucks had lesions characteristic of chronic hepatitis; ten of these had chronic active hepatitis, four had chronic persistent hepatitis, and one(More)
Eighty-nine dogs with malignant oral melanoma were selected for study. All dogs were clinically staged and treated with either surgical excision alone or surgery plus C. parvum immunotherapy. There was no difference in survival time between the two treatment groups. However, in dogs with advanced disease (Stages II, III) there was a statistical difference(More)
The case records of 100 cats with malignant mammary tumors were reviewed. All cats were staged clinically according to the staging system of the World Health Organization. The following information was obtained from the medical records: age at time of diagnosis, breed, tumor size, date of surgery, type of surgical procedure performed, histologic type of(More)
Cytologic samples of popliteal lymph node, proximal femoral bone marrow, and the buffy coat fraction of blood were obtained from 56 dogs. The number of mast cells on 1 slide of each sample was determined by microscopic examination. Eleven of 46 slides of lymph node aspirate contained mast cells (range, 1 to 16; mean, 6.4; median, 5 mast cells/slide).(More)
