摘要
目的 探讨中药对骨折愈合微血管重建的影响。方法 家兔15只,双侧胫骨制作骨折模型,左侧外敷中药,右侧未用中药为对照组。术后10、20、30天分别处死动物,将中国墨汁注射入腹主动脉,采用组织切片法,观察微血管变化,以评价中药对骨折愈合的影响。结果 中药可促进血管扩张、血管再生,增加骨折区的血供,实验组血管重建快于对照组。结论 中药可加快骨折部位血管演化过程,并保证骨折愈合过程中的血液供应,以促进骨折愈合。
Objective To explore the effect of Chinese medicinal herbs(CMH)on reconstruction of micrangium in fracture healing Methods Experimental fracture models were made on bilateral tibias of 15 rabbits,taking the left tibias applied with external CMH as experimental group,and the right tibias without CMH as control group The rabbits were sacrificed successively at 10th,20th and 30th day after operation After Chinese ink was injected into the abdominal aorta,histological sections were made to observe the changes of micrangium in callus and to evaluate the effect of CMH on fracture healing Results CMH could promote dilation and regeneration of blood vessels to increase blood supply in fracture area The reconstruction process of blood vessels in experimental group was more rapid than that in control group Conclusion CMH could accelerate the development process of blood vessels in fracture area to ensure the blood supply in the course of fracture healing
