摘要
目的观察椎板切除术后用川芎嗪并在椎板缺损处植入自体骨膜预防硬膜外粘连的效果。方法48只SD大鼠随机分成A、B、C、D4组,制作L2板损伤模型。A组硬膜外涂布生理盐水,B组硬膜外涂布川芎嗪,C组硬膜外覆盖自体骨膜,D组硬膜外涂布川芎嗪的同时加自体骨膜覆盖。术后12周对椎板切除部位进行大体观察、组织学观察、生化检查比较组间瘢痕形成和粘连情况。结果B、C、D组的改良Rydell-Balazs粘连韧度评分、胶原含量、改良Nussvuaum组织学评分均明显优于A组(P<0.01),D组优于B组与C组(P<0.05)。结论联合运用川芎嗪和自体骨膜能有效预防硬膜外瘢痕粘连和形成,比单独应用川芎嗪和自体骨膜预防效果好。
Objective To study the effect of tetramethylpyrazine cooperated with autogenous periosteum graft on fibrous scar formation in the epidural space after laminectomy. Methods 48 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. Results The 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）. Conclusion Tetrameth- ylpyrazine cooperated with autogenous periosteum graft has a better effect on prevention peridural adhesion after laminectomy.
