牙周膜

Objective To evaluate the effect of enamel matrix protein on the attachment and proliferation of periodontal ligament cells on diseased cementum surfaces in vitro.

目的观察釉基质蛋白对牙周膜细胞在牙周炎患牙牙骨质根面上附着和增殖的影响。方法用EMP处理的牙周炎患牙根片为实验组，用生理盐水处理的患牙根片和健康牙根片分别作为对照。

Objective: To evaluate the effects of PRP on the proliferation of periodontal ligament fibroblasts and the implantation of autologous growth factors and/or PDLFs to canine artificial furcation defects.

目的 研究自身生长因子PRP对牙周膜成纤维细胞增殖的影响，并和自体PDLFs移植修复犬慢性牙周组织缺损。

When tooth week the bag bag form after, alter to make piling up of food remnant, the tooth germ spot and tooth stone calculus etc., this kind of lately piles up the further breakage deeper tooth week film again, the result of thus continuous vicious cycle, eventually go to a tooth to support to organize all breakages for week almost exhausted, but make tooth difficult to escape to pull out of bad luck.

当牙周囊袋形成后，更易使食物残渣、牙菌斑和牙结石等的堆积，这种新的堆积又更进一步的破坏更深的牙周膜，如此不断的恶性循环的结果，终至牙周支持组织全部破坏殆尽，而使牙齿难逃拔除的恶运。

Objective:To develop a culture model for PDLSCs and SCAP of miniature pig and investigate the biological characteristics in vitro.

目的：分离培养小型猪牙周膜干细胞及根尖牙乳头干细胞，研究其生物学特性，为利用干细胞进行牙周及牙根组织工程打下基础。

PDLSCs and SCAP grew very well on the scaffold of HA/TCP in vitro. Conclusion:The miniature pig PDLSCs and SCAP, which can be cultured successfully in vitro, may be useful cell sources for the regeneration of periodontal and tooth tissues.

小型猪牙周膜干细胞及根尖牙乳头干细胞可被成功的分离培养，在体外表现出良好的生长状态，有望为牙周组织再生和生物牙根再生提供有用的细胞来源。

The defects were analysed histologically and histomorphologically after healing.

此结果显示牙周膜细胞膜片可作为牙周再生新的治疗方式。

To investigate the effect of insulin-like factor-Ion the proliferation activity of human periodontal ligamental fibroblasts.

目的：研究胰岛素样生长因子Ⅰ对人牙周膜成纤维细胞增殖能力的影响，为牙周组织改建工作提供理论依据。

After bridge insertion, the pontic of fixed bridge re- stored additional force, but the change of stress in the peri- odontium of premolar and molar is very diffierent.

固定桥修复后桥体承受了增加的载荷，双尖牙和磨牙牙周膜应力的变化规律是不相同的，双尖牙牙周膜应力的增加幅度大于磨牙。

To the best of our knowledge, this is the first study on the global gene expression of MSCs cocultured with periodontal ligament cells. A particular humoral factor released from periodontal ligament cells is suggested to affect differentiation and proliferation in MSCs.

本试验是第一篇关于骨髓间充质干细胞和牙周膜细胞共培养后基因表达的全面研究，我们认为来自牙周膜细胞的体液因素将影响骨髓间充质干细胞的增殖和分化。

Materials and Methods: the HPDLFs were isolated and cultured in vitro from healthy premolars of orthodontic patients, which were 10~14 years old.

材料和方法：取材自临床上10～14岁青少年需要拔除的健康的正畸牙，在体外分离、培养并纯化人牙周膜成纤维细胞，建立人牙周膜成纤维细胞有限细胞系。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
