Effects of biochanin A on bone turnover and metabolism. (A) Effects of biochanin A on osteoclast TRAP staining. TRAP+ cells are indicated with black arrows. (B) Effects of biochanin A on OCN in the alveolar bone of rats determined by immunohistochemical staining. The black arrows indicate the IHC positive cells. (C) Quantitative analysis of TRAP+ cells in five groups. (D) Effects of BA on OCN in serum of rats determined by ELISA. Data are presented as the mean ± SD, n=5 rats per group. *P<0.05, **P<0.01, and N.S. means no significant difference. TRAP, leukocyte acid phosphatase; BA12.5, 12.5 mg/kg/day biochanin A; BA25, 25 mg/kg/day biochanin A; BA50, 50 mg/kg/day biochanin A.
