Abstract
Tissue distribution of NSAIDs at lumbar region using tapes was never examined. Ten lumbar spinal canal stenosis patients were percutaneously applied GF-Na at 30 mg before surgery. Sample of blood, subcutaneous fat tissue and paraspinal muscle were taken at surgery and examined GF-Na concentration of each sample by liquid chromatography (LC/MS/MS). The concentration of GF-Na of fat and muscle were higher than that of blood.
