Paper Title:
Therapeutic Effect of Selected Biomaterials (Mg/Zn/F-CaPs, Administered by Injection) on Bone Properties of Ovariectomized Rats
  Abstract

The purpose of this study was to evaluate the efficacy of magnesium (Mg), zinc (Zn) and fluoride (F)-containing calcium phosphate compounds (Mg/Zn/F-CaP) in correcting the bone mineral deficiency noted in ovariectomized (OVX) rats. In order to evaluate therapeutic effect of selected Mg/Zn/F-BCP preparations (G2: 1.13%Mg/13.6%Zn/2.5%F, G3:7.76%Mg/1.89%Zn /3.01%F and G4:2.72%Mg/3.75%Zn/1.35%F), suspensions consisting of Mg/Zn/F-CaP preparations and of Zn-TCP (G1: 6.17%Zn) powder were injected in the right thigs of OVX rats for 4 weeks. Injection of Zn-TCP powder suspension in G1 and G2 groups led to the recovery of plasma Zn levels in OVX rats. The area under the curve of plasma Zn for the G2, G1 and Normal (not ovariectomized) control group (GN) groups were significantly lower than those of the group G3, G4 and OVX /untreated control (GC) groups (p<0.05). The bone mineral density (BMD) of the right femur was significantly higher than that of the left in G1, G2, G3 and G4 groups on day 28. However, there was no significant difference in the BMD between the left and right femur in the GC and GN groups.
