Abstract:

Objective To study the effect of the compound medicine of tanshinone 2A and resveratrol on peak bone mass in growing rats and to explore its possible mechanism,so as to explore anti-osteoporosis mechanisms of new traditional Chinese medicine (TCM) drugs. Methods Totally 40 1-month-old female Wistar rats were randomly divided into tanshinone 2A group,resveratrol group,compound group (tanshinone 2A and resveratrol),and normal control group,with 10 rats in each group. Body weight was measured once every two weeks,and the whole body bone mineral density was measured with dual-energy X-ray monthly. When the whole-body bone mineral density became statistically significant between medication groups and control group,all animals were sacrificed to determine the bone mineral density of vertebrae and right femoral bone. The biomechanical properties of femur and vertebrae were measured by AGS-X series universal test,then the bone morphology was analyzed with Fuchsin picric acid staining. Finally,the levels of tartrate-resistant acid phosphatase 5b and osteocalcin were measured with enzyme-linked immunosorbent assay.Results The body weights were not statistically significant among all groups (P>0.05). The whole-body bone mineral density showed no significant difference (P>0.05) after feeding for 1 month;however,two months later,it was significantly different between medication groups and control group;in particular,the whole-body (P=0.016),femoral (P=0.001),and vertebral bone mineral density (P=0.034),bone trabecular number (P=0.024),thickness (P=0.040),and area (P=0.038) were significantly increased in the compound group,along with the significantly decreased trabecular separation degree (P=0.032). Compared with the control group,the compound group had significantly increased osteocalcin (P=0.033) and tartrate-resistant acid phosphatase 5b (P=0.028) levels in serum.Conclusion The compound of tanshinone 2 A and resveratrol can improve the bone density and bone quality in rats,and such effect is higher than either tanshinone 2 A monomer or resveratrolmonomer.
