Total protein, albumin quota, and electrophoretic patterns in cerebrospinal fluid of dogs with central nervous system disorders.
Cerebrospinal fluid was analyzed for total protein, albumin quota, and electrophoretic patterns of albumin and alpha-, beta-, and gamma-globulins in 10 healthy dogs and 35 dogs with CNS disorders. Values obtained in healthy dogs were used to establish control data. Samples also were collected from dogs with neurologic diseases that were classified according to clinical and pathologic diagnosis as inflammation, neoplasm, and spinal cord compression. The albumin quota and total CSF albumin values were used as indicators of blood-brain barrier disturbance. Four patterns were observed on agarose electrophoresis that included intrathecal immunoglobulin production, intrathecal immunoglobulin production combined with blood-brain barrier disturbance, blood-brain barrier disturbance, and unaltered CSF. These patterns correlated with the observed clinical and pathologic conditions. Seemingly, agarose electrophoresis of CSF is a simple and reliable technique that aids in the diagnosis of CNS disorders of dogs.
