牙周膜

AIM: To get the terminal C encoding gene of Periostin from mouse periodontium.

目的： 从小鼠牙周膜组织中克隆Periostin C末端编码区基因。

Merely decreasing occlusal table width could not result in an obvious stress reduction in PDL, although it could reduce the force at the pontic.

而单纯地减小桥体〓面面积，虽然可以减小桥体所承受的〓力的大小，但对基牙牙周膜应力的降低并不明显。

For the abutment with severe bone lost, pontic width reduction can significantly reduce the stress in PDL of it, and protect the health of remaining periodontium of abutment.

对于基牙牙槽骨高度降低的固定桥，桥体减径可以更加明显地降低基牙牙周膜应力，对桥基牙起到保护作用。

Objective:To observe the biological effect of bFGF on fibroblasts from peridongal ligament,and evaluate the value of bFGF in clinical pulpal and periodontal therapy.

R781.4A1005-2720-（2010）03-0003-02目的：了解bFGF对人牙周膜成纤维细胞的生物学效应，为bFGF在牙周病中的治疗学研究提供新的实验依据。

AIM: Investigation of bio-effects of GM- CSF on periodontal ligament and pupal fibroblasts.

目的：观察GM-CSF对牙周膜成纤维细胞、牙髓成纤维细胞的生物学作用。

There were synergistical effect on proliferation, but no synergistical effect on differentiation in periodontal ligament fibroblasts on groups of rhBMP-4 plus rhIGF-Ⅰ.

rhBMP-4与rhIGF-Ⅰ联合应用，对促进人牙周膜成纤维细胞生长增殖有协同作用，但对细胞分化并无协同作用。

Results: Under the compression with a magnitude of 15KP、 30KP, the proliferation of HPDLFs greatly increased, and the percentage of the content of DNA of cells in S phase increased tooP

结果：①。OKP、15KP、30KP、45KP的持续性静压力，加力1小时后，体外培养的人牙周膜成纤维细胞增殖活性的变化为：0～15～30KP，增殖指数以及S期细胞DNA百分比都显著增高(P＜0.05)；45KP压力下，增殖指数及S期细胞DNA百分比明显降低。②。

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。

However, the mechanism how PDL cells transform mechanical signals into the activity of bone remodelling has been unclear.

但是正畸过程中牙周膜细胞受机械力后如何将力信号转化为成骨及破骨活动的机理至今仍不清楚。

Results: A 3-dimensional finite element nrodel consisting of pulp,tooth, PDL, compact bone and cancellous bone was established.

结果：首次建立了包括牙髓、牙、牙周膜、硬骨板、板质骨和外层皮质骨的三维有限元模型。

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。
