Objective:
The object of this study was to investigate the effects of licofelone on the prevention of epidural fibrosis (EF) formation in post-laminectomy rat models.
Methods:
A controlled double-blinded study was conducted in sixty, healthy adult Wistar rats that underwent laminectomy at the L1-L2 vertebrae levels. All the rats were divided randomly into three groups according to the treatment (via oral gavage): (1) licofelone treatment group; (2) vehicle treatment group; (3) sham group (laminectomy without treatment). All rats were euthanized humanely 4 weeks postoperatively. The macroscopic assessment of EF, hydroxyproline content in epidural scar tissue, histological analysis, and the mRNA measurements of interleukin-6 (IL-6) and transforming growth factor-β1 were performed.
Results:
The Rydell score, hydroxyproline content, epidural scar density, and inflammatory factors expressions all suggested better results in licofelone group than the other two groups.
Conclusion:
The application of licofelone could reduce hydroxyproline deposits, inflammatory factors expressions and prevent epidural adhesions in post-laminectomy rats.
