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.
