摘要:

目的:探讨在大鼠腭裂手术术中和术后应用云南白药和碘仿对伤口愈合的效果,寻找更适合于大鼠腭裂手术术中和术后应用的药物。方法:将90只SD大鼠随机分为对照组、碘仿组和云南白药组,每组30只。通过手术方法在大鼠硬腭部制作腭裂缺损,并根据分组在缺损中填塞云南白药或碘仿4 mg,对照组不填药物。术后应用肛门测温法测定大鼠体温,应用骨密度仪检测腭部手术区骨密度,HE染色和改良gomori特殊染色法观察新骨形成情况,免疫组织化学法检测碱性成纤维细胞生长因子(bFGF)和骨形态发生蛋白2(BMP2)表达水平。结果:术后1周碘仿组大鼠体温高于其他2组(P<0.05);术后第2、3周X射线片显示云南白药组骨密度高于其他2组(P<0.05);HE染色及改良Gomori特殊染色观察到云南白药组成纤维细胞分裂、增殖和新骨形成情况明显强于对照组和碘仿组;术后第2、3周云南白药组bFGF和BMP2表达水平高于其他2组(P<0.05)。结论:腭裂手术大鼠应用云南白药对体温无刺激性升高,而且能够促进成纤维细胞增殖,减少术后腭瘘并发症的发生,同时能够促进腭裂的骨性修复。

Abstract:

Abstract:Objective
To study the effects of Yunnan Baiyao and iodoform for rat cleft palate operation,and to find  more suitable drug for the cleft palate operation.Methods 90 SD rats were randomly divided into  control group,drug iodoform group,and Yunnan Baiyao group;there were 30 rats in each group.Through the method of operation,the rat  cleft palate defects models were set up.According to the grouping,the 4 mg Yunnan Baiyao or 4 mg iodoform werer put into the defects,and nothing in  control group.The body temperature of the  rats was detected with anal temperature measurement.Bone density meter was used to detect   the  palate operation area bone density.HE staining and modified Gomori staining were used to observe new bone formation.The contents of bFGF and BMP2 were determined by immunohistochemical method.Results The body temperature of the rats in iodoform group was higher than those in the  other two groups 1 week after operation (P<0.05).The X-ray detection results showed that  the bone density in  Yunnan Baiyao group was higher than those in the other two groups 2 and 3 weeks after operation(P<0.05).The fibroblast  division,proliferation and new bone formation were enhaced in  Yunnan Baiyao group by HE and modified Gomori special staining.The contents of  bFGF and BMP2 in  Yunnan Baiyao group were higher than those in the other two groups 2 and 3 weeks after operation(P<0.05).Conclusion Yunnan Baiyao has no irritation to temperature,and it can not only promote the cleft palate soft tissue healing,but also reduce palatal fistula complications,and it can promote the bony repair of cleft palate.
