PBC treatment improves the number of osteoblasts and reduces the number of osteoclasts of osteoporosis model rats. After the administration of lower PBC or higher PBC, distal femur was detected by OC staining (A–D; magnification, × 400) and TRACP-5b staining (E–H; magnification, × 400). The number of OC-stained osteoblasts was quantified (I). The number of TRACP-5b-stained osteoclasts was quantified (J). Sham (A, E), OVX (B, F), OVX + LPBC (C, G) and OVX + HPBC (D, H). n = 5 per group. *Vs. Sham group, P < 0.05, ^#Vs. OVX, P < 0.05, ^&Vs. OVX + LPBC group
