Collagenase and 25 m filtration web, and characterized in terms of the expression of different phenotypic markers of osteoclasts and their ability to resorb bone matrix. The phenotypic markers of DCs include the expression of tartrate-resistant acid phosphatase, acid phosphatase, resorption pit assay, reaction to calcitonin and identification of F-actin.

于37oC，5％CO。培养箱中培养1－2小时后，弃培养液：lxPBS清洗数次；0.25％胰酶－EOTA 37℃消化5分钟，加入含川％FBS的a－MEM，经小25tim过滤网过滤；IX PBS清洗末过滤细胞，即得到纯化的破骨样细胞，并进行细胞形态学和分于生物学鉴定。

In addition to the approaches described, short medial, lateral, and dorsal approaches may be made to expose small areas of the tarsal and metatarsal joints. In all, the vessels, nerves, and tendons must be protected.

除了上述介绍的手术入路外，还可采用内侧、外侧或背侧短切口入路显露跗骨间和跖跗关节的较小区域，无论何种切口，都要注意保护血管、神经及肌腱。

Res ults: The maxillary central incisor was similar to the maxillar y lateral incisor in stress distribution. The highest stresses were observed in the root surface, the liwest in the periodontal ligament, the alveolar bone between them .

结果：上颌中、侧切牙的应力分布基本相同；上颌中、侧切牙及其支持组织的应力分布不均匀，牙根部受应力最大，牙槽骨次之，牙周膜最小。

Objective: To observe the expression of bone morphogenic protein-7 (BMP-7) in the kidney of rats with unilateral ureteral obstruction, and to explore the relationship between BMP-7 and renal tubulointerstitial lesion.

目的：观察单侧输尿管梗阻大鼠模型中骨形态发生蛋白7（BMP-7）在肾组织中的表达部位，动态变化及其与肾小管间质损害的关系。

Fixation as a rule is best furnished by internal or external metallic devices. Only in an extremely unusual situation would a cortical onlay graft be indicated for fixation, and then only in small bones and when little stress is expected.

一般情况下固定最好借助于内、外金属器械，只有在极为特殊的情况下才选用皮质骨贴附移植作为固定手段，而且只用于短骨和应力很小的情况下。
