成骨

At the same time, X-ray films were examined disconnectedly, in ordering to evaluate the curative effect.

在新骨生成率上：术后1月、2月、3月、6月时，实验组的成骨率均大于对照组。

The amount of drainage,the time of patient in hospital, the union time and grade of incision were observed after operation. At the same time, X-ray films were examined disconnectedly, in ordering to evaluate the curative effect.

术后观察伤口引流量，住院天数，伤口愈合天数及愈合等级等一般情况；定期摄X线片检查，对骨愈合情况进行大体观察，并对骨修复情况参照Lane-Sandhu的X线评分标准进行评分，间接评价骨移植材料的促进成骨能力。

Together with the development of distraction osteogensis, more and more attention is paid to the implantal distractor.

随着牵张成骨技术的发展，种植体型牙槽嵴牵张器在牙槽嵴增高中的应用日益广泛。

Objective: To investigate the optimal time point to dismantle the distractor during mandibular distraction osteogenesis in goats.

目的：探讨下颌骨牵张成骨中牵张器的最佳拆除时机。

Objective: To study the long-term stability of maxillary distraction with Rigid External Distractor.

目的：初步研究探讨外置式牵引成骨技术矫治重度上颌后缩畸形术后的稳定性。

After one month,the distractor were buried into one side of mandible.

牙槽晴牵张成骨早期对牵张侧颗下领关节有一定的影响，但这种影响是轻微、可逆的。

The mechanical strain induces the up-regulation of expression of integrin α2、β1、β3 on the membrane of osteoblasts from 3control group and promoted prolifration and differentiation of osteoblasts from 3control group at 400μstrain. The expression of integrin α2、β1、β3 and Doctorship Thesis of Sichuan University------Abstractsynthesize function of bone matrix in osteobla

上述实验结果提示：16月龄大鼠复制成年人雌激素缺失骨质疏松的模型优于3月龄大鼠骨质疏松模型。2力学刺激可引起正常大鼠和骨质疏大鼠成骨细胞膜表面integrinα2、β1、β3表达

A stable and duplicable experimental dog model on study of vertical alveolar distraction osteogenesis have established successfully by the intraosseous distractors, which provides a good foundation for domestic production of alveolar distractor and clinical practice of the technique.

采用该骨内型牙槽骨牵张器成功建立稳定的、重复性好的犬牙槽骨牵张成骨动物模型，为牙槽骨牵张器的国产化和临床上应用该项技术打下基础。

Methods The isolated rat primary osteoblast-like cells were exposed to fluid shear stress 2, 4, 8, 12, 14, 17and 19 dyn/cm2 for 60 min respectively in the flow chamber. The ability of proliferation of cells was studied by flow cytometry.

方法对体外培养的大鼠成骨样细胞施加一系列不同大小的流动剪切力，利用流式细胞技术衡量其细胞的分裂增殖能力。

The proliferation indexes of the cells went up with the gradual increase of shear stress. When fluid stress reached 12 dyn/cm2, the PI of cells increased significantly (P.05), compared with the control.

随着剪切力的增加，成骨样细胞的增殖指数不断增加，当剪切力为12dyn/cm2时，PI值与对照组相比有显著性差异（P.05）。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
