目的观察中强度运动训练结合仙灵骨葆胶囊对去卵巢大鼠骨密度(bone mineral density,BMD)、骨代谢及股骨生物力学的影响,为防治骨质疏松提供实验室参考。方法50只雌性SD大鼠随机分为5组,每组10只。A组为正常对照,B组切除卵巢1周后灌胃给予1 mL生理盐水,C组切除卵巢1周后进行中等强度的运动训练(运动速度为20 m/min,每天持续时间为60 min,连续5 d/周),D组切除卵巢1周后灌胃给予1 mL仙灵骨葆胶囊[0.4 g/(kg·d)],E组切除卵巢1周后灌胃给予1 mL仙灵骨葆胶囊+中等强度的运动训练,连续治疗8周后,进行血液生化指标检测,以及股骨、L5椎体BMD、Micro-CT检测与生物力学检测。结果与B组比较,C~E组的血液生化指标均有不同程度的改善,L5椎体、股骨骨密度升高,股骨(或L5椎体)的骨体积分数、骨小梁数目、骨小梁厚度升高,骨小梁间隙与结构模型指数降低,L5椎体最大载荷、最大挠度及最大应力升高,股骨最大载荷、弹性载荷、弹性挠度、弹性模量、弹性应力、最大应力及弹性挠度升高,其中均以E组效果最明显。结论中等强度运动训练结合仙灵骨葆胶囊治疗可提升去卵巢大鼠BMD,改善骨代谢与骨微结构,提高骨力学性能,两者具有协同作用。
