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

To observe the effect of osteopractic total flavone on bone histomorphometry of osteoporosis model in rath with ovariectomized female rat models.

The ovariectomy-induced model, bone sliceswith calcium, pigmentation, and Leica Qwin image analysis system were adopted on bone histomorphometry.

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.

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.
