Bone Mineral Density and Strength of Ovariectomized Rat

This study aimed to determine changes in Bone Mineral Density (BMD) and bone strength of ovariectomized rats fed a synthetic diet of Mg, Zn, and F incorporated with carbonate apatite. Group 1 (n=4) was fed a Normal Mineral Diet (NMD) and Group 2 (n=4) was fed the Synthetic Diet (SD: 0.74% Ca, 0.48% P, 0.10% Mg, 365.4 ppm Zn, 51.01 ppm F and 0.27% CO3 ). Rats were sacrificed after eight weeks and the femur was isolated. The micro-CT results showed that values of BMD for Group 2 were higher than those of Group 1. Bone strength values of Group 2 measured by a 3-point bending test were significantly higher than those of Group 1. These results indicated that Group 2 stimulated bone quality, increased BMD and bone strength. The SD has the potential to prevent bone loss and as an osteoporosis therapy.
