Figure Lengend Snippet: FTIR analysis and bone quality of the femurs in OVX rats treated with bisphosphonates, eldecalcitol, and their combinations. Right femoral bones were harvested from sham and OVX rats after 16 weeks. (A) FTIR images with areas of high absorbance for the PO 4 3− band shown as white (or red), and areas of low absorbance for the PO 4 3− band shown as dark blue. (B) Mineral-to-collagen matrix ratio of trabecular bone, (C) carbonate-to-phosphate ratio of trabecular bone, (D) mineral-to-collagen matrix ratio of cortical bone, and (E) carbonate-to-phosphate ratio of cortical bone. Data are presented as mean + SD. n = 3 (30 × 3 spectra). ⁎⁎ p < 0.001 compared with the sham group. a p < 0.05, b p < 0.01, and c p < 0.001 compared with the vehicle group. † p < 0.05 and †††† p < 0.0001 compared with RIS. ‡ p < 0.05, ‡‡ p < 0.01, and ‡‡‡ p < 0.001 compared with ALN. # p < 0.05 and ### p < 0.001 compared with MIN. $$ p < 0.01 and $$$ p < 0.001 compared with ELD. §§§§ p < 0.0001 compared with RIS + ELD. ¶¶¶¶ p < 0.0001 compared with ALN + ELD. Abbreviations: ALN, alendronate; ELD, eldecalcitol; FTIR, Fourier transform infrared; MIN, minodronate; OVX, ovariectomized; RIS, risedronate.
