目的:观察柚皮苷( NG)联合中强度跑台运动对去势大鼠骨质疏松模型的治疗效果。方法2月龄雌性SD大鼠80只,用随机数字法分为假手术组(SHAM)、去势组(OVX)、去势+不同浓度(40、100、200 mg/kg)柚皮苷组( OVX+NG)、去势+跑台+柚皮苷组( OVX+EX+NG)、去势+跑台组( OVX+EX)、雌激素组(OVX+E2),每组10只。大鼠切除卵巢2个月后开始给药,给药60 d后观察各组大鼠股骨骨密度(BMD), Micro-CT参数,血清生化指标及及股骨力学性能与组织学改变。结果柚皮苷与跑台运动干预60 d后, OVX+EX+NG组大鼠股骨颈力学强度、股骨BMD、 BV/TV、 Tb.N、 Tb.Th等均高于单纯去势组(P<0.05), OVX+EX+NG组治疗效果与柚皮苷浓度呈正相关,以200 mg/kg柚皮苷效果最佳;200 mg/kg柚皮苷联合中强度跑台运动可进一步提高治疗效果。 OVX+NG组大鼠血清骨钙素升高,Ⅰ型胶原C端肽( CTX-1)降低; OVX+EX组大鼠骨钙素与CTX-1均降低; OVX+EX+NG组大鼠骨钙素水平与柚皮苷组(200 mg/kg)无差异,但高于OVX+EX。 OVX+EX+NG组CTX-1水平低于单纯柚皮苷组和单纯跑台组( P<0.05)。结论柚皮苷联合中强度跑台运动可提高去势大鼠股骨BMD,增加骨小梁数目,改善骨代谢指标,提高股骨力学性能。

Objective To study the effects of combined treatment with naringin and treadmill exercise on osteo-porosis in ovariectomized rats . Methods Fifty 2-month-old female rats were randomly divided into sham group (SHAM), ovariectomized group (OVX), naringin (40, 100, 200 mg/kg) (OVX+NG) group, treadmill group (OVX+EX), naringin+treadmill group (OVX+EX+NG), and E2 group (OVX+E2), ten rats in each group.After 60 days removal of both ovaries in rats , established rat model of osteoporosis .And then oral naringin and treadmill training to treat osteoporosis.Sixty days after treatment, the bone mineral density (BMD), Micro-CT, bone metabolism, mechanical strength and histological were analyzed .Results Sixty days after surgery , the BMD and number of trabecular in OVX-rats were decreased .BMD, number of trabecular and mechanical strength were increased in all groups ( P<0.05 ) .OVX+EX+NH group was better than other group ( P<0.05 ) .Compared with OVX group , osteocalcin increased and CTX-1 reduced in OVX+NG group, osteocalcin and CTX-1 were decreased in OVX +EX group.Treadmill makes osteocalcin decreased in OVX+NG group.Naringin union intensity treadmill exercise can significantly reduce the levels of CTX-1 in serum compared with OVX +NG group and OVX+EX group ( P<0.05 ) .Conclusion Naringin union intensity tread-mill exercise can increase the number of trabecular and bone mineral density in ovariectomized rats , regulation of bone metabolism, improve the mechanical properties of rat femur .
