Abstract:
Objective: To investigate the effects of resveratrol(RES)on the bone mineral density (BMD) in ovariectomized female rats. Method: Forty-eight SD female rats were randomly divided into 6 groups and treated respectively as follows:group A, sham operated; group B, ovariectomized (OVX); group C, OVX supplemented with 0.03 mg/(kg bw ?d)diethylstilbestrol; and group D, E , F: OVX rats supplemented with RES at 5, 15 and 45 mg(/kg bw ?d). The duration of exposure was 90 d and the BMDs of rats were measured by dual-energy X-ray absorptiometry (QDR-4500A). Results: BMDs at all measured sites of group B were significantly lower than those of group A. And compared with group B, BMDs of the total body, lumbar vertebrae and femur of group D, E, F were increased significantly by RES. Conclusion: The bone loss of the ovariectomized female rats could be inhibited by RES. It seemed that the inhibitory effects of 45 mg/(kg bw ?d)RES on bone loss of ovariectomized female rats were better than the other 2 dosages or 0.03 mg/(kg bw ?d)diethylstilbestrol in this experiment.
