| Outline of Final Research Achievements |
PURPOSE:Development of new osteoporosis treatment using the capacity electrical stimulation and examination of the evaluation method
MATERIALS AND METHODS:We used Wistar / ST male rat of 10 weeks of age. We resected a haploid ovary and were OVX group. In 2, 4,812 weeks, we killed an animal using pentobarbital sodium. We resected both tibias and used the left tibia for micro CT imaging for an MR image imaging with the right tibia. We assumed a part of proximal tibia 1/3 ROI and measured the evaluation of the signal-to-noise ratio by the SWIFT method and bone density in micro CT. RESULTS:SWIFT-SNR was significantly from the control group high level after surgery in OVX group as of 8, 12 weeks. CONCLUSION:The SWIFT findings suggest that the SWIFT technique may depict early changes in cortical bone quality.
