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.
除12-14岁组外，采用骨宽进行校正得到的骨密度值可较好消除骨骼体积的混杂作用。
Size adjustment by using such predefined index as BMD (BMC/BW) can correct BMC fully for bone size except those during 12-14 years old.
结果通过曲面断层片中观察发现囊肿腔内骨密度增高，有不同程度的新骨形成，囊肿体积变小。
Results Observed from orthpanotomography the density of bone in cysts increased significantly, with new bone formation and decreasing of the vulcanicity of cysts.
