查询词典 osteoid

Results The main histopathologic changes were:① experimental group: inflammatory cell infiltration (1W); inflammatory cell disappearance, fibroblast and capillary tachyauxesis, osteoid tissue and small amount neoformative bone tissue appearance (2 W); fibrous tissue decrease, neoformative bone tissue enlarging and maturity (1～3 M).

结果① 实验组：术后1周，骨缺损区周围有炎性细胞浸润，可见牙槽骨变性坏死；术后2周，炎性渗出明显吸收，成纤维细胞、毛细血管生长活跃，可见骨样组织和少量骨组织；术后1～3个月，新生骨组织范围扩大，钙化程度加强。

Many osteoid were formed around metal surface and bone graft remodeling was active in 1 month as shown by nondecalcified section.

For normal adult male rat,calcitonin depresses the osteoclastic resorption obviously through reducing the number of active resorptive surface and depressing osteoclastic activity;on the other hand,calcitonin depresses the osteoid producing activity of osteoblasts by indirectly affecting the coupling process between resorption and formation.Calcitonin administered in short did not affect the bone volume.

降钙素对正常成年雄性大鼠松质骨而言，可以明显抑制破骨吸收，这种作用可能是通过减少活性吸收表面数量和降低破骨细胞的吸收功能来完成的；可以抑制成骨细胞形成类骨质的活性，这种作用可能不是直接的，而是通过降钙素对骨吸收的抑制作用进而影响了骨吸收与骨形成的之间的偶联而完成的；短期应用降钙素骨量无变化。

Results: In the experimental group, both TBV%(the fraction of trabecular bone volume) and MTT of the condylar subchondral bone were significantly decreased, whereas the RS%(the fraction of resorptive surface) and OS%(the fraction of osteoid surface) significantly increased.

结果：实验组大鼠髁突软骨下骨小梁相对体积减小，平均宽度变薄，而骨小梁吸收表面百分比与类骨质表面百分比比对照组均增加。

To be qualified as an EOS, the tumor must (1) arise in the soft tissue and not be attached to bone or periosteum,(2) have a uniform sarcomatous pattern ( to exclude the possibility of a mixed malignant mesenchymal tumor),(3) produce osteoid and/or cartilage matrix.

本病的诊断标准是(1)发生于软组织而与骨及骨膜部不相连；(2)具有一致的骨肉瘤表象，以排除混合性恶性间叶组织肿瘤；(3)可产生骨质或软骨样基质。

RESULTS: After six weeks of implantation, x-ray film showed high-density signal, osteoid tissue formed under histological examination. Large amount of new bone were formed and connected to trabecularism 8 weeks after implantation in the experimental group.

结果 实验组6 周时大体标本浅红色， X 线片有较高密度阻射影像，组织学检查可见有新骨形成； 8 周时大体标本呈红色，质硬， X 线阻射影像密度更高，镜下可见大量新骨形成并相互连接成骨小梁样结构，骨细胞位于陷窝中。

RESULTS: During 10 - 12 weeks, in cuntrol group: The defect area was repaired by white and soft tissue that had no resistance to press. The repaired tissue was still lower than the surrounding articular surface with clear boundary. By histological observation, it was found that the defect was repaired by the mechanism similar to inflammatory reaction and the defect is ultimately filled by the hyperplasia of hyaline degenerative fibrous tissues. In filling group: the defect was repaired by semi-transparent, smooth, textured tissues with polish that had resistance to press as well as elasticity. The repaired tissue was almost similar to the shape of the surrounding cartilage,difficult to be distinguished. After histological observation, it was found that there was no inflammatory reaction, but active hyperplasia of inner bonetissue and cartilage tissues; a lot of osteoid tissues and trabeculation were found. Newlborn cartilage was fused with surrounding cartilage tissue and connected with surrounding tissues.

结果：10～12周，对照组：缺损区由白色、质软、按压无阻抗的组织修复，修复组织仍低于周围关节面，边界仍清晰可辨，组织学以类似炎症反应的机制修复缺损，最终以透明变性的纤维组织的增生来填补缺损部位；填充组：缺损区由半透明状、质韧光滑有光泽，按压有阻抗并有弹性的组织修复，修复组织与周围软骨外形上已基本相似，不易区分，组织学未见有炎症反应的过程，内骨组织和软骨组织增生活跃，并可见大量类骨组织和骨小梁形成，新生软骨和周围软骨组织融合，并与周围组织连接。

Osteoid osteomas usually occur in the axial skeleton in bone cortex of young males in the second decade of life.

骨样骨瘤常见于十几岁男性中轴骨骼的骨皮质。

Eleven cases with osteoid osteomas were treated with CT-guided percutaneous excision. The location involved were femoral neck （6 cases ）, acetabulum （ 4 cases）, humeral neck.

首先对整个瘤巢采用2mm薄层扫描，选择穿过瘤巢中心的层面，以克氏针钻入，定位瘤巢中心，在套筒保护下用环钻沿导引针将整个瘤巢切除。

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.
