The aims of the study were to standardise an immunohistochemical (IHC) method for the detection of progesterone receptors (PR) on formalin-fixed, paraffin wax-embedded tissue sections of feline mammary gland tumours and dysplasias, comparing the results with those obtained using the radiolabelled ligand dextran coated charcoal (DCC) assay applied to frozen(More)
This report describes nine unrelated cats with acute idiopathic polyneuropathy. All cats presented with acutely developing tetraparesis or tetraparalysis and loss of spinal reflexes. Seven cats recovered completely within 4 to 6 weeks, without any medication. Two years after complete recovery, none of these cats had had a relapse. In the acute stage, two(More)
An ulcerated lesion resembling a tumour in the lesser curvature of the stomach of a 3-year-old male Dobermann pinscher was found to be caused by Cryptococcus neoformans. The dog had been vomiting for two months and had slight leucocytosis and anaemia. Biopsies of the ulcerated lesion revealed granulomatous inflammation and many cryptococci, which were(More)
Twenty-eight epithelial and 22 nonepithelial feline tumors were studied immunohistochemically. Epithelial tumors were 10 squamous cell carcinomas, two basal cell tumors, two sebaceous gland carcinomas, three apocrine gland carcinomas, three thyroid papillary carcinomas, one thyroid solid carcinoma, one renal clear cell carcinoma, one renal papillary(More)
We present a case of a young dog exhibiting internal hydrocephalus, associated with parasitic granulomas within the ventricular system, inflammatory changes in the periventricular brain tissue and stenosis of the mesencephalic aqueduct. Reference is made to possible causes of these lesions in animals and man.
A one year old female Foreign White cat is described with a history of six days of unthriftiness, anorexia, anaemia and depressed temperature. The necropsy revealed multiple sessile polyps in the jejunum. Histologically a hyperplasia of the crypt epithelium with an inflammation of the mucosa and submucosa was found. A comparison of polyposis in man, dogs(More)
The essence of the cell-matrix interaction in tissues is that cells influence the composition of the extracellular matrix but that, on the other hand, components of the matrix are also involved in the regulation of growth and differentiation of the cells. Interaction is also found to occur in tumours though in a different way, so that infiltration and(More)
PURPOSE The posterior interosseous sensory nerve innervates the dorsal capsule of the wrist, which may provide nociceptive and proprioceptive sensation. Posterior interosseous sensory neurectomy (PISN) is commonly used as a primary or adjunctive procedure to provide wrist analgesia for a variety of wrist conditions. Currently, there is little information in(More)
A Holstein-Friesian heifer had shown a haemorrhagic discharge from the vulva since three days. The animal had delivered a calf nine months previously and was seven months pregnant. On admission, haemorrhagic fluid was obtained by catheterisation from the urinary bladder and by paracentesis from the abdominal cavity. At autopsy, bilateral(More)
Estrogen receptors (ER) were determined by both the biochemical dextran-coated charcoal (DCC-ER) and the immunohistochemical Avidin biotin-peroxidase complex (IHC-ER) methods in proliferative mammary lesions collected from 37 cats: 20 malignant tumors without metastasis at first presentation, seven malignant tumors with lung and/or lymph node metastases and(More)
