Five dogs with unilateral thoracic limb lameness, neurologic deficits, muscle atrophy, and pain, or a combination of these signs, were examined using ultrasonograghy. Large, hypoechoic tubular masses that displaced vessels and destroyed the normal architecture were found in each dog. The affected axilla of each patient was then imaged with computed tomography or magnetic resonance to fully assess the extent of the masses. We describe the use of ultrasound in screening patients for brachial plexus tumors. 相似文献

The cardiorespiratory effects of midazolam (0.1 mg/kg) and butorphanol (0.4 mg/kg) were evaluated in seven cats. Cats were induced in a chamber, removed and intubated, and maintained with isoflurane in 100% oxygen. Cardiorespiratory data were recorded before and 3, 10,20,30,40,50, and 60 minutes after intravenous injection of midazolam-butorphanol. Heart rate, mean arterial pressure, and respiration rate were significantly (p < .05) decreased below baseline at various times throughout the study. Tidal volume and minute ventilation were unchanged. End-tidal carbon dioxide was significantly (p < .05) increased above baseline for 30 minutes. Midazolam-butorphanol administered intravenously induced significant alterations in several cardiorespiratory parameters in isoflurane-anesthetized cats. 相似文献

Abstract— Giant cell dermatosisis is reported in six cats with evidence of concurrent feline leukemia virus (FeLV) infection. Scaling, crusting and alopecia, accompanied by pruritus, affected the head and/or face predominantly in most cats; generalized skin disease developed in one cat. Histologically, giant keratinocytes resembling syncytial cells were found in the epidermis and superficial hair follicles, and were accompanied by dyskeratosis, pustules and ulcers. Immunohistochemical staining revealed FeLV antigen in the giant cells and adjacent keratinocytes. FeLV infection may have led to neoplastic alteration of the keratinocytes through recombination with host oncogenes
Resumen Este artículo se basa en seis gatos con dermatosis de las células gigantes infectados con el virus FeLV. Éstos animales presentaban escamas y costras, así como pérdida de pelo y picor en las regiones de la cabera y cara, predominantemente. Tan solo uno de los gatos desarrolló una dermatosis generalizada. En el exámen histológico se demostró la presencia de keratinocitos gigantes con semejonza a las células sinticiales localizados en la epidermis y folículos pilosos superficiales, acompañados de disqueratosis, pústulas y ülceras. Las finturas histo-inmunológicas demostraron el antígeno FeLV en las células gigantes y keratinocitos adyacentes. La injeccion con el virus FeLV pudo haber conducido a la alteración neoplástica de los keratinocitos a través de la recombinación con los oncogenes del hospedador. 相似文献

Interference with deoxyribonucleic acid replication need not be a primary mechanism in the blockade of cell division by deuterium oxide, but current hypotheses on the molecular basis of the blockade do suggest that such interference might take place under appropriate conditions. Autoradiographic experiments support the suggestion, for whereas normal sea urchin eggs incorporate H(3)-thymidine into deoxyribonucleic acid from almost the beginning of development, cells immersed in deuterium-enriched media do not. Blockade of mitosis and inhibition of thymidine incorporation are simultaneously relieved when the eggs are returned to normal water. 相似文献

Regional perfusion of carpal tissues by forced intramedullary administration of fluids was evaluated in 10 horses. Results of subtraction radiography after perfusion with a contrast medium demonstrated that perfusate was delivered to the carpal tissues by the venous system. Perfused India ink was distributed uniformly in the antebrachiocarpal and middle carpal synovial membranes. Histologically, the ink was within the venules of the synovial villi. Immediately after perfusion with gentamicin sulfate (1 g), the gentamicin concentrations in the synovial fluid and synovial membrane of the antebrachiocarpal joint were 349 +/- 240 micrograms/mL and 358 +/- 264 micrograms/g, respectively. When gentamicin concentrations in the synovial fluid of the antebrachiocarpal joint and serum were measured 0, 0.5, 1, 4, 8, 12, and 24 hours after carpal perfusion, the mean peak gentamicin concentration in the synovial fluid was 589 +/- 429 micrograms/mL. At hour 24, the mean gentamicin concentration in the synovial fluid was 4.8 +/- 2.0 micrograms/mL. The resulting peak gentamicin concentration in the serum was 23.7 +/- 14.5 micrograms/mL immediately after the perfusion; it decreased below the desired trough level of 1 micrograms/mL between hours 4 and 8. 相似文献
