ABSTRACT

Foi realizado um estudo retrospectivo do líquido cérebro-espinhal de cães (LCE), atendidos pelo Serviço de Neurologia do Hospital Veterinário da Instituição, de 2004 a 2015, com o objetivo de analisar os resultados de cães com sinais neurológicos, comparar as alterações encontradas em dois locais de colheita no mesmo paciente e verificar se esse exame auxiliou o clínico em reforçar a suspeita clínica das principais doenças do sistema nervoso central. A pleocitose linfocítica esteve presente em 78,3% (29/37) das amostras de cães com cinomose e em 23,2% (10/43) de cães com DDIV. Houve dissociação albuminocitológica (DAC) em 73% (19/26) das amostras de cães com tumores IC e em 64,3% (9/14) de cães com tumores envolvendo a ME. Em cães com DDIV, houve significância estatística (p<0,05) entre o grau de disfunção neurológica e o total de células nucleadas (TCN) e total de proteínas (TP). Em 29 cães, houve a colheita do LCE da cisterna magna e da cisterna lombar e em 12 (41,4%) os resultados foram diferentes entre as duas amostras colhidas do mesmo cão, onde dois (6,9%) apresentaram alteração na amostra colhida cranial à lesão. Pode-se concluir que a pleocitose linfocítica foi a principal alteração encontrada no LCE de cães com cinomose e DDIV e DAC nas neoplasias, IC e ME, cães acometidos pela DDIV apresentaram sinais neurológicos mais severos conforme o TCN e o TP aumentaram e o LCE sofreu alteração, mesmo colhido cranial ao local da lesão e auxiliou o clínico em reforçar a suspeita clínica, mas não confirmou, as principais doenças neurológicas em cães.(AU)


A retrospective study including the analysis of the cerebrospinal fluid (CSF) of dogs neurologically affected was conducted by the Neurology Service of the Veterinary Hospital at the Institution, between 2004 and 2015. The aim of this study was to analyze the results of the CSF of dogs with neurological signs, and compare the changes in the CSF in two sampling sites in the same patient and see if this test helped the clinician to strengthen clinical suspicion of the major diseases of the central nervous system. Lymphocytic pleocytosis was present in 78.3% (29/37) of samples from dogs with distemper and in 23.2% (10/43) of samples from dogs with IVDD. The albumin cytologic dissociation (ACD) was found in 73% (19/26) of samples from dogs with IC tumors and in 64.3% (9/14) from dogs with tumors involving the SC. For dogs with IVDD, there was statistical significance (p<0.05) between the degree of neurological dysfunction and the total nucleated cells (TNC) and total protein (TP). In 29 dogs, CSF was collected from the cistern magna and the lumbar and in 12 (41.4%) the results were different between the samples of the same dog, where two cases (6,9%) showed alterations in the sample collected cranial to the injury. It can be concluded that the lymphocytic pleocytosis was the main alteration found in the CSF of dogs with distemper and IVDD and ACD in tumors. Dogs affected by IVDD had more severe neurological signs as TNC and TP increased and the CSF was altered even collected cranial to the lesion site and helped the clinician to strengthen the clinical suspicion, but not confirm, the major neurological diseases in dogs.(AU)

ABSTRACT

Use of acute-phase proteins (APPs) for assessment of health and disease in animals has increased greatly within the last decade. The objective was to determine the normal concentration of APPs in the serum and cerebrospinal fluid (CSF) of healthy cattle by polyacrylamide gel electrophoresis. Fifty crossbred animals (350±70kg of BW and 18±1.2 months of age), 25 heifers and 25 steers were used. CSF samples were collected from atlanto-occipital (AO) site and blood samples were obtained from the jugular vein. CSF and serum protein electrophoresis were performed by means of sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Thirty-seven proteins with molecular weights ranging from 7 and 37kDa were identified in CSF of all animals. These eight were nominally identified with immunoglobulin A and G, celuloplasmin, transferrin, albumin, α1-antitripsin, acidic glycoprotein, and haptoglobin. All protein fractions in CSF did not differ between heifers and steers. In sera, 34 proteins with molecular weights between 7 and 244kDa were identified in heifers and steers. Similar proteins were nominally identified in the sera, but only the CSF presented α1-antitripsin. The serum values of acidic glycoprotein and immunoglobulin G were significantly higher in steers compared with heifers. In conclusion, measurement of CSF acute phase protein concentrations can be useful in diagnosing and monitoring the progression of bovine neurological diseases, perhaps even to guide therapeutic procedures. The CSF electrophoretic profile of healthy cattle does not change depending on gender.(AU)


O uso de proteínas de fase aguda (PFAs) para a avaliação da saúde e da doença em animais de produção tem aumentado consideravelmente na última década. O objetivo deste estudo foi determinar a concentração normal de PAFs no soro e no líquido cefalorraquidiano (LCR) de bovinos sadios por meio da eletroforese em gel de poliacrilamida. Foram avaliados cinquenta animais mestiços (350±70kg de PV e 18±1,2 meses de idade), 25 novilhas e 25 novilhos. As amostras de LCR foram colhidas no espaço atlanto-occipital (AO) e as amostras de sangue obtidas da veia jugular. As PAFs do soro e do LCR foram determinadas através da eletroforese em gel poliacrilamida. Trinta e sete proteínas com pesos moleculares que variaram entre 7 e 37kDa foram identificadas no LCR de todos os animais, independente do sexo. Estas oito proteínas foram nominalmente identificadas como imunoglobulina A e G, ceruloplasmina, transferrina, albumina, α1-antitripsina, glicoproteína ácida, e haptoglobina. As frações de proteínas presentes no LCR não diferiram entre novilhas e novilhos. No soro de machos e fêmeas, 34 proteínas com pesos moleculares entre 7 e 244 kDa foram identificadas. As proteínas do soro foram similarmente identificadas, entretanto a α1-antitripsina foi identificada somente no LCR. Os valores séricos de glicoproteína ácida e imunoglobulina G foram significativamente mais elevados nas novilhas em comparação aos novilhos. Em conclusão, a determinação das concentrações de proteínas de fase aguda presentes do LCR pode ser útil no diagnóstico e monitoramento da progressão de doenças neurológicas bovinas, talvez possa ainda direcionar procedimentos terapêuticos. O perfil eletroforético do LCR de bovinos hígidos não se altera em função do sexo.(AU)
