Objective:To investigate the effects of mouse recombinantPeriostin on proliferation and ALP activity of periodontal ligament cells.

目的：研究小鼠重组Periostin对牙周膜细胞增殖及碱性磷酸酶活性的影响。

The results were examined histologically 1 month and 3 months respectively. In experimental groups the JE downgrowth was inhabited in the early healing, and the new attachment formation was promoted while comparing with controls.

结果与对照组比较，FG、ePTFE膜组和e-PTFE膜+FG组均可显著促进根分叉区牙周组织的再生，且FG、ePTFE膜组之间没有显著差异，而e-PTPE膜+FG组在一月时可更好的促进牙槽骨的再生。

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 epithelial pegs and dermal papillae were long and slender, with infiltration of inflammatory cells underlying connective tissue.

利用牙周膜干细胞进行牙周组织再生可获得较好的效果，为临床应用提供大型动物的实验依据。

The limitation young people parodontitis and the fast progress parodontitis method of treatment selects the tetracyclin textile fiber membrane generally.

局限型青少年牙周炎和快速进展型牙周炎的治疗方法一般选用四环素纤维膜。

Objective:To recombine the plasmid PcDNA3.1-sTNFRⅠ,and detect the expression of recombinant plasmid in pericementum cell,and evaluate the bioactivity of expressed sTNFRⅠ.

目的：构建真核表达质粒PcDNA3.1-sTNFRⅠ，并转染人牙周膜细胞观察是否有目的产物的表达，研究其是否具有生物学活性，为进一步研究其在牙周治疗中的作用提供实验基础。

It has been showed that human periodontal ligament cell is a kind of polyclonal cells and play a great part in the course of periodontium reconstruction.

人牙周膜细胞(human periodontal ligament cell，hPDLC)作为牙周组织中的主要功能细胞，具有多向分化潜能，在创伤修复和组织再生中发挥着重要作用。

The tests of permeability and TEER were consistent with the demands of development of drug transport cell models. HPDLF and HGF drug transport cell models could be used to study drug transport by HPDLF and HGF in vitro.

所建模型在2周后细胞排列情况可模拟体内牙周膜和牙龈生理状态，且符合模型建立要求，可作为研究牙周细胞转运药物的体外模型。

The purpose of the study was to evaluate quantitatively PDLC attachment and proliferation to periodontally diseased human cementum and dentin after demineralizing with minocycline- HCl and EDTA.

以往关于用四环素族药物处理根面的研究，均是以牙本质为载体，而临床上牙周手术后与牙周膜细胞接触的界面主要是牙骨质表面。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
