Biochemical evaluation of the cerebrospinal fluid from clinically normal dogs and from young dogs with distemper enchephalitis / Avaliação Bioquímica do líquido cefalorraquidiano de cães normais e de cães jovens portadores de encefalite por cinomose

ABSTRACT

Cerebrospinal fluid samples were obtained from 20 normal dogs and from 20 dogs with canine distemper encephalitis, for biochemical evaluation. Blood samples were taken simultaneously and the values of chlorides, glucose, creatine phosphokinase and glutamic oxaloacetic transaminase were determined to verify if there is any correlation between those constituents from blood and from cerebrospinal fluid. Biochemical evaluation of the cerebrospinal fluid from normal dogs were glucose concentration 86,09 ± 17,76 mg/dl, chloride levels 117,36 ± 21,35 mEq/L, creatine phosphokinase levels 3.77 ± 1.72 Ul/L and glutamic oxaloacetic levels 7.43 ± 4.61 Ul/L. Biochemical evaluation of the cerebrospinal fluid from dogs with distemper encephalitis were glucose concentration 88.85 ± 14.82 mg/dl, chloride levels 118.67 ± 12.82 mEq/L, creatine phosphokinase levels 26.38 ± 29.27 Ul/L and glutamic oxaloacetic levels 65.70 ± 23.72 Ul/L. Chloride, creatine phosphokinase and glutamic oxaloacetic seric levels and glucose plasmatic concentration in normal dogs and in dogs with distemper encephalitis were, respectively, 103.43 ± 16.00 and 103.43 ±11,99 mEq/L, 95.75 ± 22.83 and 272.50 ± 140.95 Ul/L, 23.77 ± 5.20 and 23.44 ± 4.81 Ul/L, 119.12 ± 21.46 and 106.12 ± 17.73 mg/dl. There was a positive correlation between the glucose plasmatic concentration and the glucose concentration in cerebrospina

RESUMO

O presente experimento teve como objetivos estabelecer padrões de referência para constituintes do líquido cefalorraquidiano, determinar os valores de cloretos, creatina fosfoquinase e aspartato aminotransferase no soro sangüíneo e dosagem de glicose plasmática, na tentativa de verificar se existe correlação entre essas variáveis no sangue e no liquor, de cães normais e de cães jovens portadores de encefalite por cinomose. Foram utilizados 40 animais, sendo 20 cães normais e 20 cães com cinomose. O exame bioquímico do liquor dos cães normais permitiu o estabelecimento de valores para concentração de glicose 86,09 ± 17,76 mg/dl, níveis de cloretos 117, 36 ± 21,35 mEq/L, níveis de creatina fosfoquinase; 3,77 ± 1,72 Ul/L e níveis de aspartato aminotransferase 7,43± 4,61 Ul/L. O exame bioquímico do liquor de cães com cinomose permitiu o estabelecimento de valores para concentração de glicose 80,85 ± 14,82 mg/dl, níveis de cloretos 118,67± 12,82 mEq/L, níveis de creatina fosfoquinase 26,38 ± 29,27 Ul/L e níveis de aspartato aminotransferase; 65,70 ± 23,72 Ul/L. Os níveis de cloretos, creatina fosfoquinase e aspartato aminotransferase no soro, e glicose no plasma nos cães normais e nos cães com cinomose foram, respectivamente, 103,43 ± 16,00 e 103,43 ±11,99 mEq/L, 95,75 ± 22,83 e 272,50 ± 140,95 Ul/L, 23,77 ± 5,20 e 23,44 ± 4,81 Ul/L, 119,12 ± 21,46 e 106,12 ± 17,73 mg/dl.
