The normal parameters of cerebrospinal fluid for glucose; protein, globulin, urea, creatine kinase (CK), aspartate aminotransferase (AST), leukocytes, color, turbidity and coagulation in dogs.

Abstract

The normal parameters of cerebrospinal fluid (CSF) for glucose, protein, globulin, urea, creatine kinase (CK), aspartate aminotransferase (AST), leukocytes, color, turbidity and coagulation were determined in healthy dogs. Twenty adult mongrel dogs, 13 males and 17 females were submitted to a total of three cisternal punctures with an interval of 2-3 weeks between the collections. Following the procedures, the samples of cerebrospinal fluid were analysed for physical, chemical and cytologic aspects. Each determination was performed twice, in order to evaluate the employed method. The physical examination showed the CSF to be colorless, clear and no coagulation occured in 6 hours chemical and  cytologic examinations results, average and standard deviations, are the following: glucose 3.59 ± 0.42 irmol/l; protein 0.20 ± 0.06 g/l with traces of globulin; urea 5.99 ± 2.4 mmol/l; aspartate aminotransferase (AST) 32.72 ± 12.20 U/L; creatine kinase (CK) 17.1 ± 1.0 U/L and an average of 0.6 cel/µ in the leukocyte count.
