成骨的

In this study, the curative effect of distraction osteogenesis on temporomandibular joint ankylosis was observed.

目的：传统的手术方法治疗颞下颌关节强直的弱点就是高复发率，观察新出现的治疗技术牵引成骨术治疗颞下颌关节强直的效果。

Three experimental groups of the cultured rat osteosarcoma cells underwent simulated weightlessness in rotating clinostat for 24, 48 and 72 h respectively.

目的 通过观察回转条件下培养的大鼠骨肉瘤细胞内Ⅰ型胶原的基因和蛋白表达的变化，探讨模拟失重对成骨细胞增殖功能的影响。

METHODS: Calvarial osteoblasts of neonate rats were cultured under conditions of normal gravity(1G) and simulated weightlessness induced by clinostat respectively. The total RNA in cells was isolated in different time points (24, 48, 72 h). Reverse transcription PCR analysis was made to examine the gene expression of α5,αv and β1 integrin subunits. Each value was normalized against that of β actin mRNA.

培养的大鼠乳鼠颅骨成骨随机分为对照组和失重组，在实验的24， 48和72 h提取细胞总RNA，进行反转录PCR，检测整合素的α5，αv和β1亚单位mRNA表达，并计算与内参照β肌动蛋白 mRNA水平的比值。

According to the bone apposition events at the interface, we measured the osteoblast attachment rate with the hemocytometer, the osteoblast growth curve with modified MTT method, the ALPase activity and protein content of cellular layers with modified kinetic method and modified Coomassie'method respectively, and osteocalain content in the cell medium with RIA , at different levels of cell responses, as osteocompatibility indexs.

根据骨内种植体界面的骨愈合过程，分别从成骨细胞反应的不同层次选择了细胞贴壁率、细胞生长曲线、细胞层ALPase活性和蛋白质含量以及细胞培养液中骨钙素的含量作为体外评价材料骨性生物相容性的指标。采用细胞计数板计数法测定细胞贴壁率，采用改良MTT法测定细胞生长曲线。

B The micropipette aspiration technique was used to study the effects of cyclic stretching on the mechanical property of rat calvirial osteoblasts which were loaded at 500με, 1000μεand 1500μεrespectively with the frequency of 0.4Hz.

利用微管吸吮技术研究应变分别为500με、1000με和1500με，频率为0.4Hz的周期性拉伸刺激对大鼠颅盖骨中分离出的成骨细胞的力学特性的影响。

Mandibular distraction osteogenesis perhaps causes a temporarily negative effect on the condyle, which will undergo a long remodification process to be resumed.2.1mmunohistochemical study of type I and III collagen in condyle in mandibular distraction osteogenesisResults: The expression of type I collagen increased more slowly.

犬双侧下颌骨牵张成骨中髁状突软骨Ⅰ、Ⅲ型胶原变化的研究第四军医大学硕士学位论文结果：犬躲状突软骨中1型胶原的表达增加缓慢，至牵张结束8周仍有超常水平；Ill型胶原的表达随时间的延长逐渐增加，至牵张结束4周达到顶峰，随后逐渐减弱。

The self-centering mechanism design of bipolar endoprosthesis has advocated the use of offset centers of rotation between the inner and outer joint bearing surfaces to generate a self-centering moment on loading to prevent impingement of polyethylene rim and stem neck or cup fixed at wrong place. The design was used popularly, but the function of self-centering mechanism was discussed in very few papers. Three bipolar endoprosthesis were evaluated: UNIQHIP system, UHR system, and AML system.

双极式半人工髋关节的离心复位机构，是利用髋臼外帽的球心与股小球的球心两者在不同点，来防止发生髋臼外帽固定於髋臼中某角度卡住不动，而使股骨柄颈部固定磨损超高分子聚乙烯内衬之一边缘，进而加速超高分子聚乙烯内衬之磨耗，造成骨溶蚀与人工髋关节的松脱。

Only in 5th day during distraction, did gently atrophy appear in the masseters probably due to occlusal interference but subsequently disappeared.

但是在牵张完成后它们都通过改建在新的位置上重新形成了稳定的肌肉结构，这种变化从理论上讲有利于牵第四罩巴大学硕士论文张成骨术后的稳定。

Objective: Basic Fibroblast Growth Factor is a mitogen for many cell types, including osteoblasts and chondrocytes. It can stimulate angiogenesis and oateoblast gene expression.

目的：碱性成纤维细胞生长因子是许多种细胞的丝裂原，其可促进血管的生成及成骨细胞基因的表达。

But interestingly, this proliferation activity was not observed in 10% NCS-MEM or 4% BSA-serum free MEM.

有趣的是sOGP在体外的成骨活性作用必须有血清白蛋白和血清中某些因子的参与。

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。
