Fig. 1. Concentrations of methylprednisolone (mean ± SD) in pig spinal cord dialysates after either intravenous (IV) or intrathecal (IT) administration. TC-IT = thoracic cord—IT delivery; LC-IT = lumbar cord—IT delivery; TC-IV = thoracic cord—IV delivery; LC-IV = lumbar cord—IV delivery. All data were corrected for dialysis probe efficiency.
