醫(yī)學(xué)論文范文:益骨口服液對去勢大鼠骨密度與骨生物力學(xué)的影響
【摘要】 [目的]探討益骨口服液對實驗去勢大鼠骨密度和骨生物力學(xué)變化的影響。[方法]將大鼠隨機分為A、B、C、D、E五組，A組(10只)為正常對照組(假手術(shù)); B組(10只)為模型組(造模后給予蒸餾水亦即空白組);C組(10只)為陽性對照組(切除雙側(cè)卵巢并予以倍美力治療);D組(10只)為高濃度組(造模后給予含生藥1.5g/ml益骨口服液治療);E組(10只)為低濃度組(造模后給予含生藥0.5g/ml益骨口服液治療)。灌胃12周后，活殺各組動物，以雙能 X線測定骨密度及三點彎曲試驗測生物力學(xué)指標。[結(jié)果]治療組骨密度明顯高于模型組(P<0.05)，骨生物力學(xué)性能較模型組得到明顯改善(P<0.05)。結(jié)論：益骨湯能促進骨形成，能提高骨強度及生物力學(xué)性能。

Abstract： [Objective] To observe the effect of YiGu Oral Solution on bone structure and bone biomechanics.[Methods]Rats were randomly divided into A，B，C，D，E five groups，A group(10)for the normal control group(sham operation);B group(10)as a model group(distilled water model that is，after the blank group);C group(10)for the positive control group(resection of bilateral ovarian and western medicine treatment Premarin);D group(10)for the high concentration group(model after treatment with 1.5g/mlYiGu Oral Solution Pharmacognosy );E group(10)for the low concentration group(model after treatment with 0.5g/mlYiGu Oral Solution pharmacognostic).Twelve weeks after oral administration of live animals in each group to kill in order to dualenergy Xray density of bone mineral density determination.[Results]BMD was significantly higher than the model group(P<0.05)，than the mechanical properties of bone biology has marked improvement in the model group(P<0.05).[Conclusion] YiGu Oral Solution can promote bone formation and improve the mechanical properties of bone biology醫(yī).學(xué)全.在.線quanxiangyun.cn.
