Abstract:
ObjectiveTo study the effect of tetramethylpyrazine cooperated with autogenous periosteum graft on fibrous scar formation in the epidural space after laminectomy. Methods48 SD rats were divided randomly into 4 groups. Laminectomy was performed in lumbar 2 segment, and the exposed duras were covered with saline solution (group A), tetramethylpyrazine (group B), autogenous periosteum (group C), and tetramethylpyrazine and autogenous periosteum (group D) respectively. 12 weeks postoperatively, they were evaluated with the gross and histopathological observation, biochemistry examination. ResultsThe assessment of Rydell-Balazs and Nussbaum's Criterion of group B, C, D were obviously better than that of group A (P<0.01), and that of group D was superior to group B and C (P<0.05), no significant difference between group B and C (P>0.05). ConclusionTetramethylpyrazine cooperated with autogenous periosteum graft has a better effect on prevention peridural adhesion after laminectomy.
