The results of MTT , ALP , OCN and areas of newly formed trabeculae of the experimental group and the control group were evaluated with paired t test respectively .

采用配对t检验，分别对实验组和对照组的MTT、ALP、OCN和新生骨小梁面积进行统计学分析。

Proliferation and differentiation of bone stromal cells were determined by detecting the level of alkaline phosphatase ( ALP ) and osteocalcin ( OCN ) in the culture medium .

通过碱性磷酸酶和骨钙素检测来确定骨髓基质细胞的增殖和分化情况，将诱导的骨髓基质细胞浓缩后复合到制备好的脱细胞骨块内进行培养。

The cells in culture were identified using immunocytochemistry by expression of cementum attachment protein ( CAP ), osteocalcin ( OCN ) and alkaline phosphatase ( ALP ) .

免疫细胞化学方法检测CDC中与骨相关的标志物如骨钙素、碱性磷酸酶和特异性牙骨质附着蛋白的表达；

After osteoblasts induction , the cells changed from spindle-shape to cuboidal and polygonal in cell morphology . The ALP , type I collagen , OCN expression were positive .

诱导培养后细胞形态由纤维状变成多角形，ALP、Ⅰ型胶原、骨钙素染色呈阳性。

RT-PCR showed the β - TCP ceramics could increase osteocalcin ( OCN ) gene expression , this made the osteoblast into a new mature stage , improved the activity and promoted the differentiation of osteoblast .

RT-PCR显示β-TCP陶瓷增强了成骨细胞OCN的表达，使成骨细胞进入一个新的成熟阶段，提高成骨细胞的活性，促进其向骨细胞分化。

Result : In cell culture , bFGF promoted the cranial suture cell to secrete the collagen and OCN ( Osteocalcin ), and promoted the proliferation of S-phase cell ( p < 0.05 ) .

结果：在大鼠颅缝分离培养细胞中，bFGF促进颅缝分离培养细胞分泌胶原、骨钙素，加快细胞增殖生长曲线平台期出现，并有效促进大鼠颅缝分离培养细胞S期增殖（p<0.05）。

Osteoblasts secrete alkaline phosphatase ( ALP ) and osteocalcin ( OCN ) which increase intercellular connection and message transmission . The processes extended from the surface of the cells and formed the intercellular connection .

成骨细胞分泌碱性磷酸酶（Alkalinephosphatase，ALP）、骨钙蛋白（osteocalcin，OCN），共同增加细胞间的连接和信息的传递，增强细胞的成熟。

Morphologic changes of osteoblast were observed , the proliferation were detected by MTT method , the activity of ossification were studied by alkaline phoaphatase ( ALP ) and osteocalcin ( OCN ) .

倒置显微镜下观察细胞的生长形态，MTT法检测成骨细胞增殖情况，碱性磷酸酶及骨钙素（OCN）测定成骨细胞活性。

The third chapter discussed the OCN marketing environment . We figured out that it is a good opportunity for OCN to promote the DTV business based on the analysis of PESTEL , value chain and the Industry Life Circle .

第三章着重于讨论东方有线的外部营销环境，我们通过PESTEL模型、产业生命周期以及价值链分析和指出了目前是大力发展数字电视业务的有利时期。

The ALP , Alizarin red , Von Kossa staining results are positive after Osteogenic induction . by immunofluorescence and RT-PCR detection , ALP , OPN , OCN , and ONN are expressed .

成骨诱导后进行ALP、茜素红、VOnKossa染色结果均为阳性，通过免疫荧光和RT-PCR检测，ALP、OPN、OCN和ONN均有表达。

The morphology of these adherent cells had no apparent change when cultured in the osteogenic medium , ALP expression increased , OCN and Col I secreted , but no calcium deposition could be detected by von Kossa staining .

向成骨细胞诱导后细胞形态变化不大，ALP增多，骨钙素和Ⅰ型胶原染色阳性，矿化结节染色显示无钙沉积。

With a various of new business is currently being expanded and the number of users is also increasing , constantly of the Orient of China Net ( OCN ), a lot of pressure and challenges has been increased for operation and maintenance increased of the OCN business system .

目前东方有线OCN正在扩展各类新业务，用户数也在不断增加，对OCN业务系统的运维增加了很大的压力和挑战。

Results : After bone marrow stromal cells were treated with different concentration of simvastatin for 72 h , level of OCN mRNA increased , and expression of OCN and OPN also increased in a concentration dependent manner , and cellular ALP activity significantly increased in a concentration dependent manner .

结果：辛伐他汀作用72h后，OCN的mRNA表达水平增高，OCN、OPN蛋白表达水平增高，呈剂量依赖关系，细胞ALP染色增强，ALP比活性显著增高。

Cyanate ester ( CE ) resin is a kind of novel high-performance thermosetting resins , which contains two or more isocyanate functional groups ( & OCN ) . Since its appearence in the late 70s of 20th century , its unique structure has attracted wide attention of people .
