牙周膜的

Similarly, the alveolus is attached to the root by the periodontal ligament and is in turn pulled along by the movement of the root.

同样，肺泡附在根的牙周膜，并反过来又退出了沿线的运动的根源。

Movement of a tooth by extrusion involves applying traction forces in all regions of the periodontal ligament to stimulate marginal apposition of crestal bone.

运动牙齿的挤压涉及申请牵引部队在各地区的牙周膜，以刺激边缘沉积的crestal骨头。

GM-CSF had dual effects on the cell growth,it could inhibit the fibroblasts proliferation at concentration abov e 1mg/L while stimulate the cell growth at concentration between 1mg/L and 0 .001mg/L.

GM-CSF的浓度在0.001～1mg/L之间对牙周膜成纤维细胞、牙髓成纤维细胞有明显的增殖效应，大于1mg/L时对增殖有明显的抑制作用。

Positive staining of Stro-1 was found in 7.6% of SCAP. Morphologically, PDLSCs were fusiform-shaped, with many short and long ramifications under a scanning electron microscope, and the secreted extracellular matrix were around them.

透射电镜下可见，第1～3代牙周膜干细胞及根尖牙乳头干细胞生长良好，胞浆内线粒体，高尔基体和粗面内质网丰富，随着培养时间的延长，分泌的细胞外基质增多。

Results: The extract of cemental matrix could enhance the initial attachment of human gingival fibroblasts and human periodontal cells to the surface of root, and such effects were strengthened with increasing density and time.

且牙骨质基质提取物促牙周膜成纤维细胞附着的作用高于对牙龈成纤维细胞的作用。

Non-occluding teeth with a hypofunctional periodontium have a lower rate of bone remodeling, and are more susceptible to the injury in periodontal tissues caused by orthodontic force than normally occluding teeth, such as hyalinization or undermining bone resorption, even dentin resorption.

正畸治疗中，无咬合接触的牙周膜废用性萎缩牙较正常咬合接触牙对矫治力反应差，骨改建率低，易发生玻璃样变和潜掘性骨吸收，延缓牙移动，因此对无咬合接触牙的临床治疗中应采用轻力。

Res ults: The maxillary central incisor was similar to the maxillar y lateral incisor in stress distribution. The highest stresses were observed in the root surface, the liwest in the periodontal ligament, the alveolar bone between them .

结果：上颌中、侧切牙的应力分布基本相同；上颌中、侧切牙及其支持组织的应力分布不均匀，牙根部受应力最大，牙槽骨次之，牙周膜最小。

Moreover, the effect of conditioned medium from cultures of HPL cells (CM-HPL cells) on the proliferation and mineralizing capacity of hMSCs was examined.

同时采用人牙周膜细胞的条件培养液对骨髓间充质干细胞的增殖和矿化能力进行分析。

The normal strain on the surface of the periodontal ligament is assumed as the mechanical stimulus proportional to the absorption rate of alveolar bone in each week.

选用一个正畸患者的下颌尖牙，建立包括牙齿、牙周膜、牙髓、牙槽骨的三维实体模型，通过有限元计算得到初始应变分布。

Results: There were no significant differences between the healing process of frozen ATMC and that of fresh ATMC, and the fibres of regenerated periodontal membrane which maintained the dental root in normal position could be imbedded in the newly formed cementum.

结果：两组自体牙-下颌骨复合组织块移植后愈合过程相似；再生的牙周膜将牙根维持在原来的位置上，牙根尖发生轻微吸收。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
