Mandibular distraction osteogenesis perhaps causes a temporarily negative effect on the condyle, which will undergo a long remodification process to be resumed.2.1mmunohistochemical study of type I and III collagen in condyle in mandibular distraction osteogenesisResults: The expression of type I collagen increased more slowly.

犬双侧下颌骨牵张成骨中髁状突软骨Ⅰ、Ⅲ型胶原变化的研究第四军医大学硕士学位论文结果：犬躲状突软骨中1型胶原的表达增加缓慢，至牵张结束8周仍有超常水平；Ill型胶原的表达随时间的延长逐渐增加，至牵张结束4周达到顶峰，随后逐渐减弱。

RESULTS: Distraction osteogenesis implants contained intraoral or extraoral distraction device, which could be used for distraction of transport plate.

结果：牵张成骨植入物分为口内牵张器和口外牵张器，可进行转移盘的牵引。

Using the following methods to treat one patient of congenital absence of the tibia with fork-shaped lower femur, the caput fibulae forming unstable knee joint, and concomitant knee flexion 95 degree.

方法1例先天性右胫骨完全缺如，股骨下端呈叉状，腓骨头与股骨下端形成不稳定的膝关节，伴屈膝畸形95 ，于1岁半实施股骨下端修整术，5岁和8岁时分两期安装Ilizarov膝关节牵伸器，牵拉矫正屈膝畸形达到伸膝0 位，使腓骨头与股骨下端成膝关节，拆牵伸器后装配能稳定膝关节的下肢补高矫形器行走。

This indicated that geniohyoid paralleling with the direction of distraction presents adaptive changes such as muscular hypertrophy and muscle fiber type transformation.

这说明与牵张方向平行的颊舌骨肌在牵张过程中出现了肌肉增生与肌纤维类型转变等适应性变化，而与牵张方向垂直的嚼肌受其影响不大。

Animals were divided into control group and 5 experimental groups. Each experimental group had 2 canines and the central of masseters and geniohyoid were dissected out in 5th, 10th day in distraction and 2nd, 4th, 8th week after distraction.

牵张器采用口内下颌骨牵张器，截骨部位在第三乳前磨牙与第一恒磨牙间且垂直于下颌骨下缘，牵张方向为前后向。

Histological examination demonstrated bone formed in accordance with intramembranous ossification in distraction zone and bony connection between the transport disc and mesial mandible on right side; On the left side, there was a big defect at the area of both distraction and defect zone because of dislocated bone transport disc, and no obvious new bone regeneration was found.

组织学检查：见9周后右侧牵张区形成新生骨质，符合膜内成骨，传送盘与近中牵张区形成骨性连接；左侧由于骨传松盘离开缺损区，牵张区与缺损区形成一较大的凹陷，未见明显新骨形成。

The periostea of both experimental and control side of the mandibular ramus were taken and prepared, 2 of each 5 rabbits in a group were prepared for HE stain detection and 3 for proliferating cell nuclear antigen immunohistochemical detection.Results:1, The newly formed bone was detected on the lateral aspect of mandibular ramus after periosteal distraction. The bone was shaped like a hill. It looked very low and was full of holes at postoperative day 28. With the time of consolidation period lengthened, the newly formed bone matured gradually. X-ray examination showed the new bone shaped like a hill. The average values of new bone height at postoperative days 28,35,42 and 56 were 1.86 + 0.15mm, 2.29 + 0.29mm,3.19 + 0.13mm and 4.70 + 0.45mm. Histological examination of both HE stain and picricacid-fuchsin stain showed the increase in the number of osteoblasts and the change in the orientation of collagen fibers and bone trabecula. There were no significant differences between newly formed bone and original bone on the lateral aspect of mandibular ramus at postoperative day 56 histologically.2 Compared with the control side, the distracted periostea proliferated obviously under the microscope, and the number of periostealcells increased with satiation of cellular nuclear per unit area. The images of PCNA immunohistochemical stain of periosteum showed that the experimental periosteum proliferated obviously after distraction compared with the control side.

结果：骨膜牵张成骨的实验研究南京医科大学硕{学位论文l、骨膜牵张后，可见下领升支外侧的骨皮质上有新骨形成，新骨呈山峰状凸起，术后第28天的新生骨较低平，多孔隙，随着固定时间的延长，新骨逐渐成熟；下领升支前后向切线位X线投照显示新骨呈山峰样隆起；经测量，术后第28、35、42和56天组平均新生骨厚度分别为x.86士0.15mm、2.29士0.29mm、3.19士0.13mm和4.70 土0.45mm；脱钙骨组织的HE染色和不脱钙骨组织的苦味酸一品红染色的组织学观察均显示了新生骨在成骨细胞数量上的增长，以及胶原纤维和骨小梁排列方向上的变化，术后第56天的新生骨在组织学上与原升支骨组织已无明显区别。2、HE染色显示，与对照组相比较，实验侧骨膜增生明显，细胞间排列紧密，单位面积内骨膜细胞数增多，细胞核饱满；骨膜PCNA 免疫组化染色显示，与对照侧相比较，实验侧骨膜在牵张后出现了明显的增生迹象，PCNA阳性细胞分布紧密，单位面积内阳性细胞数较对照组多，靠近骨表面的骨膜中的阳性细胞数更多而且分布更为紧密。

C. the total draft:the draft without slubby yarn which is count in the same way of the normal technical draft(the count of the fly frame／the basic spinning count)*efficiency.

c。总牵伸也就是没有竹节部分的纱支牵伸，与正常工艺牵伸算法是一样的：(粗纱的号数／所要纺的基纱号数)*运行效率。

Results Histological investigation showed that the bone trabeculae were disarrayed containing dispersed cartilage cells in the denervated side, whereas the bone trabeculae disarryed orderly with rich blood vessels and no cartilage cell in the control side.

结果 实验侧牵张间隙骨小梁分布方向较杂乱，骨小梁内部有分散的软骨岛分布；对照侧牵张间隙骨小梁主要沿牵张方向分布，血管丰富，成骨细胞活跃。

After 1 month, box-shaped oesteotomies of the alveolar bone were carried out and TiNi-SMAdistractors wereburied .

在牵张手术前、术后、术后1周的每日及牵张完成后1个月，分别测量术区颌骨高度，并在术后、术后1周及牵张完成后1个月拍X线片。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.
