Method for comparative studies of the revascularisation processes in the bone tissue, using 85Sr.

85SR was used for the local blood flow measurements in bones. A method for dynamic analysis of the magnitude of local blood flow based on 7-min analysis of the area under the logarithmic curve was presented. The radioactivity of the tibial diaphysis was followed by a gamma-scintillation dectector focused on the area of approximately 10 mm 0. The revascularisation process during bone repair after the osteotomy of the tibial diaphysis fixed intramarrowally was observed on 14 rabbits, two and four weeks after the osteotomy. In the first two weeks following the osteotomy the process of revascularisation was significantly enhanced in a comparison to the second two weeks.
