title: [Three dimensional observation on revascularization and study on bone metabolism of allogenic transplanted mandible].
abstract: In order to observe stereological correlation between new vessels and surrounding tissue, 6 rabbits were used for the following experiments. The mandible defect model was made by cutting 1 cm x 0.5 cm bone from both right and left side of mandible. Then, the left defect was repaired by the bone segment from the right side, and the right defect was repaired by frozen allogenic bone segment. One month later, the metabolism of the bone segments was observed by nuclein scintiphotography. The revascularization of the bone segments was observed by vascular corrosion cast method. It was shown that new vessels from host soft tissue could penetrate the periosteum of allogenic transplanted bone, along the absorbing path, ingrowth into the bone. The metabolism of the bone was active. It was suggested that the vessel growth from host to the graft is one of the main patterns of revascularization.
