变骨

Bone grid can have unit line quality, dual line qualitative change, there will be qualitative change mixed line.

骨格线可以有单位线质、单位线质的变冻，也可以有混不不不合线质的变冻。

Moreover, the border of resorptive lacuna became clouding.

与对照组相比，培养第三、五、七天10~(-5)mol／L、10~(-4)mol／L、10~(-3)mol／L NaF组骨片上骨吸收陷窝的数量和面积均减少，差异有统计学意义(P＜0.05)，而且陷窝周缘也变得模糊。

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。

Ten cases which were first found showed regular oval shape, 4 of 5 recurred lesions appeared as irregular shape. On bone algorithm reconstruction of CT, 11 lesions revealed heterogenous "ground-glass like" mild hyperdensity or hyperdensity masses compared with brain tissue with cystic areas, stippled calfication was seen in 1 cases, the typical eggshell like bony capsule in 7 cases, 5 cases under it showed ring or arc hypodensity line.

CT表现：11例于骨窗上均呈密度不均匀的&磨玻璃&样略高密度或高密度肿块影，内部均可见大小不等的囊变区，1例伴点状更高密度钙化影，7例肿瘤周边可见特征性&蛋壳样&骨壳形成，其中5例于其内侧可见到环形或弧线形底密度影。

Results There was moderate or strong negative correlation among the indexes of the degeneration of intervertebral disc including the relative area of vascular bud, the ratio of the uncalcified and the calcified layer, the quantitation of collagen type Ⅱand the indexes of osteoporosis including the thickness ratio of cortical bone, the relative area of bone trabecula, the density of femoral bone and vertebral body bone, the max stress and straining of bone.

结果 骨质疏松相关指标骨皮质厚度指数、骨小梁相对面积、股骨密度、椎体骨密度与椎间盘退变指标终板血管芽相对面积、非钙化/钙化层比值、Ⅱ型胶原定量之间存在中度到强度的负相关，而与Ⅹ型胶原表达存在中度到强度的正相关，其中椎体骨密度与软骨终板的Ⅹ型胶原相关性最强。

Patients in later series had neither risk factors for osteonecrosis nor osteonecrosis at other extraskeletal sites; instead osteoporosis and significant cardiovascular morbidity/atherosclerosis was found in most of the patients.6,19,21 Other findings suggesting an ischemic etiology in these patients is absent enhancement on MRI of the affected vertebrae,7,15,20 "ischemic bone" noted intraoperatively,14 and vertebral body biopsies demonstrating reactive bone/fibrosis and occasionally osteonecrosis and hyalinized marrow.

以后病例系列中的患者既没有引起骨坏死的因素，在其它地方也没有出现骨坏死，而是骨质疏松症和显著的心血管疾病/动脉粥样硬化发病率[6，19，21]，其他的发现表明，在这些患者受影响的椎体上MRI不会出现增强影[7，15，20]，术中可看到&缺血性的骨块&[14]，椎体活检可看到有活性的骨/纤维化，有时可见骨坏死和玻璃样变[8，11，14，16，17，30，31]。

They are composed of dense lamellar bone originating from the medial maxillae and are covered with erectile mucosal tissue.

他们由上颌骨内侧突出的致密板层骨构成，上方覆盖能肿胀变硬的粘膜组织。

Results Ovariectomy caused attenuation and interuption in trabeculae of bone and reduced mineral deposition on the trabacular surface.

结果：卵巢切除可引起大鼠骨小梁变细、中断，骨小梁表面钙盐沉积减少。

Results ①Of 82% OSAHS patients' sleep indices were normal after the oral appliance therapy;②Compared to the control group,the patients with OSAHS had narrower upper-posterior airway volume and shorter distance from tip of the uvula to the posterior pharyngeal wall and lower positioned hyoid bone and shorter tongue before treatment;③Compared to before treatment,the OSAHS patients after therapy had lower positioned and shorter and flatter tongue,the upper hyoid bone,more anterior and downward mandibular and wider upper-posterior airway volume.

结果 ①82%患者治疗后睡眠指标达正常标准；②与配对组相比OSAHS患者上气道后间隙及悬雍垂尖至咽后壁距较窄，舌骨至下颌平面距较大，舌较短；③戴入口腔矫治器后患者舌体下降，舌变短而平坦，舌骨上移，下颌骨前下方移位，上气道后间隙扩大，与配对组比较，除舌体下移外其它测量项目值差异无显著性。

结果 ①82%患者治疗后睡眠指标达正常标准；②与配对组相比OSAHS患者上气道后间隙及悬雍垂尖至咽后壁距较窄，舌骨至下颌平面距较大，舌较短；③戴入口腔矫治器后患者舌体下降，舌变短而平坦，舌骨上移，下颌骨前下方移位，上气道后间隙扩大，与配对组比较，除舌体下移外其它测量项目值差异无显著性。

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。
