结论去势雌性大鼠骨丢失是骨转换加快（高转换型）和重建负平衡骨吸收超过骨形成所致，血清中NO和NOS的变化可能发挥着重要作用；

Conclusion The reason of bone-decrease in emasculated female rats is the negative balance between osteal conversion and rebuilding-bone absorption is quicker than bone rebuild . The change of NO and NOS in serum perhaps plays an important role in the course .
