目的:探讨降钙素对去势兔的人工假体四周骨密度和生物力学的影响。
AIM: to investigate the influence of calcitonin on the bone mineral density (BMD) and biomechanics around the artificial prosthesis in ovariectomized rabbits.
结果:与假术组比较,去势组胫骨骨小梁体积百分比(TBV%)明显下降(P<0.01),股骨头、股骨近端和远端骨密度(BMD)明显下降(P<0.05)。
Results:Compared with Sham group the percentage of TBV was significandy decreased (P<0.01) and the BMD at femoral head, proximal of femur, distal of femur were also decreased (P<0.05) in OVX group.
