CARACTERíSTICAS FíSICO-QUíMICAS E CITOLóGICAS DO LíQUOR DE OVINOS SADIOS DA RA A SANTA INêS

The occurrence of neurological disease is widespread in clinical medicine of domestic animal, but there are few studies documenting the normal composition of cerebrospinal fluid (CSF) in ovine, especially Santa Ines breed. This study establishes the parameters for normal physiochemical and cytological analysis of cerebrospinal fluid as an aid for diagnosis of neurological disorders in this breed. For this, 40 adult ovine animals, aged between six and 18 months, were used for puncture of lumbosacral CSF. The aspect and color shower a clear and colorless pattern. The average density was 1.006 ± 0.0064, protein concentration was 25.27 ± 6.64 mg/dL and glucose concentration was 46.89 ± 10.99 mg/dL. Enzymes had concentration averages of 116.72 ± 80.79 U/L for creatine kinase; 17.43 ± 11.91 U/L for lactate dehydrogenase and 17.08 ± 3.85 U/L for aspartate aminotransferase. The results for the global cell count were 4.61 ± 4.96 leukocytes/μL (0 to 15 lymphocytes, 0 to 10 monocytes, 1 to 14 neutrophils). Considering the lack of reference data for the physiochemical and cytological CSF analysis of Santa Ines ovine breed, it is recommended that the results obtained in this study are considered normal values for the breed.
