摘要:

背景:力学性能指标是评价药物治疗骨质疏松动物模型效果的重要方法,以压缩力学性能指标评价多种药物治疗老龄雌性骨质疏松模型动物的效果评价鲜有报道。
目的:对大鼠股骨进行压缩力学性能实验,确定不同药物治疗骨质疏松的效果。
方法:Wistar雌性大鼠36只随机分为6组:正常组对照组、模型组,丹杞颗粒组,阿法D3组,结合型雌激素组,依普拉芬组,每组6只。除正常组对照组外以去卵巢法复制老龄骨质疏松动物模型,分别以丹杞颗粒、依普拉芬、结合型雌激素(倍美力片)、阿法D3进行治疗,饲养15周后以腹主动脉放血法处死大鼠,取大鼠左、右侧股骨在电子万能实验机上以5 mm/min实验速度进行压缩实验。
结果与结论:骨质疏松模型组大鼠股骨最大载荷、最大应力、最大位移、最大应变、弹性模量显著低于正常对照组、丹杞颗粒、依普拉芬、结合型雌激素组(P < 0.05);阿法D3组各项力学性能指标与模型组差异无显著性意义(P > 0.05);丹杞颗粒治疗组上述指标与正常对照组大鼠差异无显著性意义(P > 0.05)。结果说明,模型组大鼠由于骨质疏松导致股骨压缩力学特性发生改变。依普拉芬、结合型雌激素组均能提高大鼠股骨压缩力学特性,丹杞颗粒效果最好。

Abstract:

BACKGROUND: The mechanical index is an important method for the evaluation of the therapeutic efficiency of drug treatment for osteoporosis animal models.

OBJECTIVE: To explore the effects of various drug treatments on osteoporosis through a mechanical performance test about the femoral compression of rats.
METHODS: Thirty-six Wistar female rats were randomized into six groups: normal control group, model group, Dan Qi particles group, alpha-D3 group, premarin group, ipriflavone group, with six rats in each group. Osteoporosis models were made in all groups except for the normal control group, and after modeling, the rats in different groups were treated with Dan Qi particles, alpha-D3 group, premarin and ipriflavone, respectively. After 15 weeks, the rats were killed by abdominal aortic bloodletting to take out the left and right femurs that were placed on a universal testing machine to perform a compressive test at a speed of 5 mm/min.

RESULTS AND CONCLUSION: The maximum load, maximum stress, maximum displacement, maximum strain, and elastic modulus were significantly lower in the model group than the other four groups (P < 0.05). There was no difference in different mechanical parameters between alpha-D3 group and model group as well as between Dan Qi particles group and normal control group (P > 0.05). These findings indicate that osteoporosis leads to the variation of compression mechanical properties of the femur. There are good compression mechanical properties of the femur after treatment with premarin and ipriflavone, and Dan Qi particles has the best effect.
