骨碎补总黄酮对去卵巢大鼠骨密度和骨组织形态计量学影响

目的 :以卵巢切除雌性大鼠为模型 ,观察骨碎补总黄酮对骨质疏松模型大鼠的组织形态计量学的影响。方法 :去卵巢制作模型 ,制作不脱钙骨切片及染色 ,采用LeicaQwin图象分析系统进行骨组织形态计量。结果 :对胫骨骨小梁体积百分比 (TBV % )的影响 ,与模型组比较 ,骨碎补总黄酮小剂量组和中剂量组的TBV %明显增高 ;对胫骨骨小梁吸收表面百分比 (TRS % )的影响 ,与模型组比较 ,骨碎补总黄酮小剂量组、中剂量组的TRS %显著降低 ;对胫骨骨小梁形成表面百分比 (TFS % ) ,活性生成表面百分比 (AFS % ) ,骨小梁矿化率 (MAR)和骨小梁骨生成率(BFR)的影响 ,骨碎补总黄酮小剂量组、中剂量组的TFS % ,AFS % ,MAR ,BFR较模型组皆明显降低 ;对胫骨类骨质平均宽度 (OSW)和骨皮质矿化率 (mAR)的影响 ,骨碎补总黄酮中剂量组的OSW和mAR与模型组比较 ,明显降低 ;骨碎补总黄酮小剂量组与之相比 ,有下降的趋势 ,但无统计学意义。结论 :给去卵巢大鼠灌服骨碎补总黄酮 6个月后 ,TBV %明显增高 ,TRS %以及TFS % ,AFS % ,MAR ,BFR ,OSW ,mAR均明显降低 ,表明骨碎补总黄酮对卵巢切除所致的骨质疏松症具有明显的防治作用。

Effect of osteopractic total flavone on bone mineral density and bone histomorphometry in ovariectomized rats

Objective:To observe the effect of osteopractic total flavone on bone histomorphometry of osteoporosis model in rath with ovariectomized female rat models. Method:The ovariectomy-induced model, bone sliceswith calcium, pigmentation, and Leica Qwin image analysis system were adopted on bone histomorphometry. Result:As compared with the model group, the effect of small dose group and middle dose group of osteopractic total flavone on TBV% of shankbone increased significantly; the effect of small dose group and middle dose group of osteopractic total flavone on TRS% of shankbone reduced significantly and TFS%, AFS%, MAR, BFR of shankbone reduced obviously; the effect of middle dose group of osteopractic total flavone on OSW and mAR reduced obviously, the effect of small dose group of osteopractic total flavone on them had the tendency of reducing, but there was no statistical significance. Conclusion:The ovariectomized rats having been fed with osteopractic total flavone for 6 months, TBV% increased significantly while TRS%, AFS%, MAR, BFR, OSW, and mAR reduced obviously. It indicates that the therapeutical effect of osteopractic total flavone on ovariectomy induced osteoporosis model is significant. And the ovariectomy induced osteoporosis model is a high transformative type of osteoporosis model in which bone absorption is higher than bone formation.
