去卵巢组血浆中PAI降低，可能与卵巢激素的减少有关。
The decrease of the plasma PAI in ovariectomy group was probably re-lated to the ovarian hormone.
麻醉后，去卵巢组大鼠切除双侧卵巢，假手术组仅行开腹术。
After anesthesia, rats in the ovariectomized group were treated with bilateral ovariectomy, and those in the sham-operated group were only given laparotomy.
结论：去卵巢组血浆中PAI降低，可能与卵巢激素的减少有关。
Conelusion: the lower plasma PAI activity in ovariectomized rats maybe related with the lower ovarian hormone.
去卵巢后全心重量和体重之比及左心室重量和体重之比明显高于未去卵巢组；
The heart to body weigh ratio and left ventricle of heart to body weigh ratio in ovariectomied rats were significantly higher than that in non ovariectomied rats.
去卵巢术后实验组(去势组)为0.15%的低钙饮食。
After surgery, the OVX group was fed on a 0.15% low-calcium diet.
单独短期低钙饮食因素对股骨生物力学影响不显著，但去卵巢大鼠配以低钙饮食后（OL组），可显著降低股骨硬度、能量吸收、韧性等生物力学指标。
Significant decrease of biomechanical markers, stiffness, energy absorption and toughness was observed in OL group, but not in those with short-term low calcium intake only.
