Table 2.
Microarchitecture of trabecular and cortical bones at the left femurs. Rats in the O group were ovariectomized. Rats in OE and OESr were subjected to 10 impacts per day, 5 days a week for 8 weeks. Rats in Sr and OESr groups received 625 mg/kg/day of SR. The critical p-value was p ≤ 0.05; NS: non-significant; a: vs. Sh; b: vs. O; c: vs. OE; d: vs. OSr and e: vs. OESr.
