| Outline of Final Research Achievements |
The protein levels of NGF and BDNF in discs from patients with disc herniation and hose from discs of patients with other lumbar degenerative disc diseases were examined. Nucleus pulposus tissue (or herniated disc tissue) was surgically removed and homogenized; protein levels were quantified using ELISAs for NGF and BDNF. Levels of NGF and BDNF in the discs were compared between 1) patients with disc herniation and those with other lumbar degenerative disc diseases, 2) patients with back pain and those with slight or no back pain, and 3) moderately degenerated discs and severely degenerated discs. Mean levels of NGF and BDNF in discs of patients were: NGF (herniation: 83.4; others: 64.8, pg/mg total protein); BDNF (herniation: 36.5: others 16.2, pg/mg total protein). Herniated discs showed significantly higher levels of NGF and BDNF (p<0.05). No significant differences were found between patients with and without back pain, or between moderately and severely degenerated discs.
