New bone formation was observed to be increasing significamly in both DCN bone cements and DC bone cements with the passage of time. By the end of 24 weeks, new bone had bridged the gap between the proximal and distal fragments in DCN bone cements and DC bone cements. By histomorphological detection in DCN bone cements, Abundant of chondral and new bone islands were seen at the site of defects 4 weeks after the operation and a number of new bones formed and enlarged by both enchondral ossification and appositional formation by the 8th weeks.

研究发现，DCN骨水泥植入4周大量间充质细胞分化，在材料与骨端之间出现一层软骨细胞，软骨细胞继续增生并向编织骨分化；8周材料降解的同时，小梁骨出现；12周新骨长入材料并已经基本替代完成，形成初步骨性连接；24周骨缺损完成骨性连接，新骨进行结构改建，材料内部形态结构明显变化。

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.

RESULTS:① Gross observation: At 2 weeks, there were no differences between the two groups, and the materials were connected to bone bed with fibrous tissues. At 4 and 8 weeks, there was more new callus in biologic active bone group than in biologic bone group. At 12 weeks, some bionic biphasic ceramic-like biologic active bone were absorbed and new bone regenerated in biologic active bone group, being similar to appearance of host bone, but there were few callus in biologic bone group.

The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

Breast cancer commonly metastasizes to bones, producing both osteolytic and osteoblastic deposits. Different markers for quantitative determination of bone turnover have been developed to evaluate bone metastases of breast cancer. The urinary deoxypyridionline, a crosslink product of collagen molecules found in bone and excreted in urine during bone degradation, and bone specific alkaline phosphatase, an isoenzyme localized in the membrane of osteoblasts and released in circulation during bone formation, were recently described as a group of markers of bone turnover in metastatic cancer.

乳癌患者常见骨髓转移造成溶骨性及成骨性沈积物，而利用不同标记来定量骨质转换形态，可以评估乳癌骨骼转移的变化，而尿液中Deoxypyridinoline是骨质内胶原分子在骨骼破坏分解时至尿中的产物，骨特殊碱性磷酸酵素是一种同形酵素，位於成骨细胞的外膜且在骨骼形成时释放至血液中，利用此两种生化标记，可以来预测乳癌转移至骨骼的转换情形。

In the second part of this thesis. The biological process of porons HA/bBMP composite repairing experimental defect in the dog femora and monkey mandibular were investigated by the qualitative and quantitative methods. The results showed that not only were the speed and time of new bone ingrowing into the bBMP/HA composite much quicker and earlier than that of implants of HA alone, but also the quantity of new bone ingrowth into bBMP/HA composite was much higher than that of HA alone. The bone ingrowth of bBMP/HA composite at higher rate within 3 weeks. In this study, bBMP/HA promoted more active new bone formation in bone marrow tissue than did HA alone. This reveals that BMP, brought into the bone marrow with HA as a carrier, accelerates osteogenesis or osteoinduction, providing sime bone marrow cells with more differentiative potential.
