中文摘要:
目的：研究硒对骨折愈合的影响。
方法：应用40只家兔做成双侧肱骨中段实验性骨折，随机分为2组：对照组饲常规饲料；实验组每日加饲微量元素硒0.6mg.术后2、3、4、5周取材，进行骨痂横截面积测量，光镜及电镜观察。
结果：实验组2～4周骨痂内的软骨细胞、成骨细胞等及基质的变化较对照组出现早，且功能活跃。
结论：饲料中加硒可促进兔骨折愈合, 这可能与硒刺激软骨细胞的蛋白合成有关。 |

ABSTRACT
Objective:To study the effect of trace element,selenium(Se)in the healing process of fracture.
Method:s Forty rabbits had been made experimental fractures at the middle shaft of the humerus bilaterally and divided into two groups randomly:the control group,fed with common forage;the experimental group,fed with Se(0.6mg/day)additionally.The specimens were taken out 2,3,4,and 5 weeks after operation,cross sections of the calluses were made to measure the area of the callus and to observe the structures with light and electron microscope.
Results: At 2 and 4 weeks,the appearance of chondrocyte and osteoblast and the changes of matrix in the callus of experimental group were much more earlier and the function of chondrocyte and osteoblast was more active.
Conclusion: Se added in forage could stimulate the synthesis of protein in chondrocyte to promote the healing of rabbits fracture. |
