醫(yī)學論文范文:益骨口服液對去勢大鼠骨密度與骨生物力學的影響
【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); 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指標。[結果]治療組骨密度明顯高于模型組(P<0.05),骨生物力學性能較模型組得到明顯改善(P<0.05)。結論:益骨湯能促進骨形成,能提高骨強度及生物力學性能。

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).學全.在.線m.payment-defi.com.
