骨痂

AIM: To explore the effects of axial stress regulation on healing of lengthened callus.

目的：探讨轴向应力调节在延长段骨痂愈合中的作用。

Over the last fifty years, ultrasound has also been studied in relation to the stimulation of bone callus.

在过去50年里，超声波在刺激骨痂形成方面的作用也曾被研究过。

Differentiation of chondrocyte in callus has a relationship with the expression of intracellular matrix.

骨痂软骨细胞的分化与其细胞外基质的表达关系密切。

Histology showed a marked increase in the size of the cartilaginous soft callus.

组织学显示出了软骨质的柔软的骨痂的尺寸的标记的增加。

The biological effect of VEGF and TGF-β〓 benefits the differentiation, proliferation and apoptosis of chondrocyte in callus.

VEGF和TGF-〓的生物学作用有利于骨痂软骨细胞的分化、增殖和凋亡。

Observations were made in three groups on the effect of detumescence, pain-relief, callus growth and clinical duration for fracture union.

观察各组在消肿、止痛、骨痂生长、骨折临床愈合时间等方面的情况。

Callus ; Bone transplantaion ; Fracture fixation ; intramedullary ; Fractures ; ununited

骨痂；骨移植；骨折固定术；髓内；骨折；不愈合

Serial radiographs of rat femurs were examined at postoperative 2, 4, 6 and 8 weeks to observe the new bone callus and bone defect healing.

植入后2，4，6，8周摄X射线片检查观察各组新生骨痂和骨缺损愈合情况。

Results:The positive expression of P53 and c－Myc protein in nuclei was bound up with poor-differentiated tumours;the positive expression of Fas and c－Myc protein in cytoplasms was consistent with well-differentiated tumours.

采用免疫组织化学方法对骨肉瘤、骨化性纤维瘤、骨纤维结构不良和正常骨痂组织进行c－Myc、Fas和P53蛋白测定，与肿瘤组织学分级、细胞分化及核丝分裂比较分析。

SEM showed that after the absence of HA granules from the surface, fibroblast started ingrowing and fresh callus came into being. This indicated that HA/PDLIA composite material had certain bioactivity and bone connectivity.

通过SEM研究表明：HA颗粒从材料表面脱落后，成纤维细胞向组织内长入，并伴有少量新生骨痂的形成，显示HA/PDLLA复合材料具有一定的成骨性和骨连接性。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
