破骨细胞

Total RAN was extracted from osteoblasts using guanidine, and mRNA expression of OPG and RANKL were examined using RT-PCR.

成骨细胞骨形成功能的减退和/或破骨细胞骨吸收作用的增强可造成代谢性骨病，如骨质疏松。

The tibiale cortex and bone cell have increased in examination with microscope. The number and function of osteoblast have increased, ossein was improved, number and function of osteoelast were controls in examination with electron microscope.

透射电镜的观察，则进一步证实了其作用机理可能是增加了成骨细胞的数量和活性，抑制了破骨细胞数量和活性，从而增加了骨形成，减少了骨吸收。

Results MMP-2 immunohistochemical results indicated that the MMP-2 expression increased and was observed on both sides periodontium of movement tooth, osteoclast, cementoblast, osteocyte, fibroblast and osteoblast appeared positive.

结果MMP-2免疫组化结果显示牙齿移动后，牙周膜两侧MMP-2表达增加，破骨细胞、骨细胞、成纤维细胞和部分成骨细胞MMP-2染色阳性。

A line of osteoblasts is present a the center-right forming new bone, but lacunae containing multinucleate osteoclasts are at the center left and lower center destroying bone.

一行成骨细胞正在中右部形成新骨，而腔隙内的多核破骨细胞正在中左与中底部破坏骨。

The results showed that the cells had classic characteristics of osteoclasts: multinucleated giant cells, staining positively for TRAP in cells, forming bone absorptive lacunae on the bone slices.

结果表明，直接分离的细胞具有典型的破骨细胞的形态特点：属多核大细胞，TRAP染色阳性，能在骨片表面形成吸收陷窝。

It may result from increased osteoclastic activity and decreased osteoblastic acyivity.

由于成骨细胞的功能活性降低和破骨细胞的功能活性增高，致使骨形成和骨吸收失平衡，导致净骨量丢失，易于骨折。

Brane, such as synoviocytes, macrophages, osteoclasts and TNF-αvv acts on different kinds of cell in synovial memchondrocytes, which can produce metalloproteinase,collagenase, stromelysin and so on, further induce pannus formation, joint inflammation, bone erosion and cartilage degradation.

TNF-α可作用于RA关节组织中的滑膜细胞、巨噬细胞、软骨细胞和破骨细胞，使这些细胞活化，产生金属蛋白酶、胶原酶、基膜溶解酶等，导致局部炎症反应和血管翳形成，进一步引起软骨破坏和骨侵蚀。

The mechanical strength, solubleness and the capability to induce ossification of the materials could be improved obviously when strontium was added, which were formed of hydroxyapatite and tricalcium phosphate.

试验研究证实锶盐具有抗骨吸收和增加骨形成的作用，锶盐可以抑制破骨细胞的活性，促进成骨细胞的活性，促进骨盐的沉积；其与羟基磷灰石和磷酸三钙等复合后，其机械强度、溶解性及诱导成骨能力等特性明显得到改善；锶盐口服有治疗骨质疏松症的作用。

Disorderly orientation and a age of the collagen structure of trabeculae were manifested.

大量功能活跃的破骨细胞出现，成骨细胞功能相对减退，向骨细胞转化。

Results of IHC confirmed that ER located mainly in cytoplasms and nuclei of osteoblast, in addtion to its location in osteocyte and osteoclast, which meets the results of abroad reports.

本研究免疫组化结果证实：雌激素受体定位于成骨细胞的胞浆和胞核。除此之外，骨细胞及破骨细胞中也存在ER。这一结果与国内外研究报道相符。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
