Mensuração do lactato plasmĂĄtico em felinos domĂ©sticos hĂgidos
Monografia (graduação)âUniversidade de BrasĂlia, Faculdade de Agronomia e Medicina VeterinĂĄria, 2015.Este estudo teve como objetivo mensurar e interpretar os nĂveis de lactato sanguĂneo em gatos domĂ©sticos, padronizando os valores para a espĂ©cie. Foram avaliados 40 gatos, machos e fĂȘmeas, com idade entre um e sete anos e sem raças definidas. Foram coletadas amostras de sangue venoso da veia safena medial do membro pĂ©lvico direito, as quais foram utilizadas para a mensuração da lactatemia de cada indivĂduo. Durante a contenção fĂsica para os procedimentos, visou-se o menor estresse possĂvel e a oclusĂŁo vascular ocorria imediatamente antes da coleta sanguĂnea, evitando a estagnação sanguĂnea momentĂąnea. Foi observado que a maior frequĂȘncia de animais (72,5%) encontra-se com o nĂvel de lactato entre 2 a 4 mmol/L. Mediante tais dados, pode-se direcionar uma conduta terapĂȘutica baseada nos valores de lactato sanguĂneo, aos pacientes crĂticos nos centros de terapia intensiva, clĂnicas e hospitais veterinĂĄrios.The aim of this study was to measure and evaluate blood lactate levels in domestic cats, standardizing the values for the species. It were evaluated 40 cats, male and female, aged between one and seven years and without defined breeds. Venous blood samples of the medial saphenous vein of the right hind limb were collected, which were used for the measurement of blood lactate concentration of each individual. During physical restraint for procedures, it was aimed at the lowest possible stress and vascular occlusion occurred only immediately before blood collection, avoiding the momentary blood stagnation. It was observed that the highest frequency of animals (72.5%) was in the level of lactate from 2 to 4 mmol / L. By these data, one can direct a therapeutic approach based on blood lactate values, to critically patients in intensive care units, clinics and veterinary hospitals
Immunopathological findings in a cat with auricular chondritis
At clinical examination, a 5-year-old male domestic short-haired cat exhibited painful swelling and erythema of the pinnae of both ears. Microscopically, the lesions on both pinnae were composed of diffuse granulomatous chondritis with degeneration and necrosis of the pinnal cartilage. Numerous mast cells were also observed within and surrounding the inflammatory lesion. Immunohistochemistry showed a mixed inflammatory infiltrate characterised by the predominance of macrophages (CD68+, MAC 387+ and Lysozyme+), T lymphocytes (CD3+), some B lymphocytes (CD79α+) and neutrophils. Immunopathological characterisation of the lesion showed a granulomatous inflammation profile and suggests that the morphological changes and immunopathogenesis of auricular chondritis in cats presents a similarity with relapsing polychondritis in humans
