成骨

Both POB and COB could keep the terminal differentiation after being seeded with HAAM.

骨膜成骨细胞与颅骨成骨细胞在与生物衍生材料接触后，仍可保持终末的分化性状。

Four traditional Chinese medicines showed activities of stimulating both osteoblastic proliferation and differentiation, they are Psoralea corylifolia L.

其中有4种补肾中药既能促进成骨样细胞增殖，又能促进成骨样细胞分化，它们是：补骨脂、槲寄生、淫羊藿、川牛膝。

This study also showed that the effect of"kidney-tonifying"traditional Chinese medicines on strengthening bone may be related to their direct effect on osteoblast, and that the flavonoid compounds in Psoralea corylifolia L. might have activity of anti-osteoporosis.

大量中药及植物促进成骨样细胞骨形成活性筛选结果表明，补肾中药的"壮骨"作用可能与其对成骨细胞活性的促进作用有关，中药补骨脂中的黄酮成分可能具有防治骨质疏松的活性。

The "regulable osteoinduction microcirculation/microenvironment system in vivo" has characteristics as follows: the culture conditions are controlled. For example, the release of a variety of growth factors can be controlled stably and quantitatively at bone defect site. Early nutrition and revascularization in the center of tissue-engineered bone can be effectively solved; some shortcomings resulted from construction of tissue-engineered bone in vivo, including secondary injury, high level technical requirements, and complex operation, can be avoided; vascularization and osteogenesis can be constructed simultaneously; simple safe and efficient operation.

可调控的体内灌注诱导成骨微循环系统具有以下特点：可以控制诱导培养条件，如调控各种生长因子微量稳定的缓控释放；能有效解决大块组织工程骨中心部位的早期营养和血运重建难题；避免了组织工程骨体内构建存在的二次损伤，需要较高的技术条件、操作较为复杂等缺陷；实现血管化与成骨的同步构建；操作简便，安全高效。

When comparedwith group Ⅱ, in group Ⅲ, uterine mucosa became thick, cavum uterihad big folds, the number of glandulae uterinae increased, secreta wasseen occasionlly, blood vessels increased, cross axle of uterus becamethick.

为了检测它的吸收成分对成骨细胞增殖的作用，我们将药物吸收成分加入培养液，结果：补肾方剂药物吸收成分对成骨细胞增殖无作用(P＞0.05)。

The cell proliferation and differentiation were measured as index of stimulating osteoblastic bone formation. Cell proliferation was assayed by MTT method with fluoride sodium as positive control.

以成骨样细胞的增殖和分化为活性检测指标，成骨样细胞的增殖以MTT法测定，氟化钠为阳性对照药。

Then the concentration of NO in supernatant of culture and the changes in histomorphometry were examined.

体内NO主要来源于成骨细胞及骨髓细胞[3] ，而骨髓基质细胞是成骨细胞的主要来源。

Abstract］objective: effects of a single period of mechanical strain on gene expression patterns of two osteogenic transcription factors, ets1 and cbfa1, in rat calvarial sutural osteoblast-like cells were studied in this study to elucidate the molecular mechanism of suture distraction.

摘要］ 目的：探讨大鼠颅骨缝成骨细胞在张应力作用下ets1和cbfa1基因表达的变化，以揭示骨缝牵张成骨的分子机制。

The results shows that the response of human osteoblasts to cyclic tensile strain in gene level was complicate.

周期性牵张力对成骨细胞多种基因的表达产生了影响，成骨细胞的应力反应是一个复杂的，多基因参与调控的过程。

The results show that the response of human osteoblasts to cyclic tensile stress in gene level was complicated.

周期性牵张力对成骨细胞多种基因的表达产生了影响，成骨细胞的应力反应是一个复杂的，多基因参与调控的过程。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
