Figure Lengend Snippet: The differences of optimal vibration frequency for accelerating OTM between the younger group and the older group (A and B) Micro-CT images and statistical analysis showed the orthodontic teeth of the younger rats in L-Vib group moved the farthest. Scale bar: 2 mm. Mean ± SD. n = 4–5. ∗ p < 0.05. ∗∗ p < 0.01. ∗∗∗ p < 0.001. (C) The content of CTX-1 in serum of the younger rats in control group, L-Vib group and H-Vib group was detected by ELISA. Mean ± SD. n = 3. ∗ p < 0.05. ∗∗ p < 0.01. (D and E) Representative images of TRAP staining of alveolar bone of the younger rats in control group, L-Vib group and H-Vib group, and statistics on the number of osteoclasts. AB, alveolar bone; R, root; PDL, periodontal ligament. Scale bar: 200 μm. Mean ± SD. n = 4. ∗ p < 0.05. ∗∗ p < 0.01. ∗∗∗ p < 0.001. (F) Immunofluorescent images of COX-2 and IL-6 in alveolar bone of the younger rats in control group, L-Vib group and H-Vib group. Scale bar: 100 μm. (G) WB results showed that the protein expression levels of COX-2 and IL-6 of the younger rats in L-Vib group were higher than those in control group and H-Vib group. Mean ± SD. n = 3. ∗∗ p < 0.01. ∗∗∗ p < 0.001. (H and I) Micro-CT images and statistical analysis showed the orthodontic teeth of the older rats in H-Vib group moved the farthest. Scale bar: 2 mm. Mean ± SD. n = 5. ∗ p < 0.05. ∗∗∗ p < 0.001. (J) The content of CTX-1 in serum of the older rats in control group, L-Vib group and H-Vib group was detected by ELISA. Mean ± SD. n = 3–4. ∗ p < 0.05. ∗∗ p < 0.01. (K and L) Representative images of TRAP staining of alveolar bone of the older rats in control group, L-Vib group and H-Vib group, and statistics on the number of osteoclasts. AB, alveolar bone; R, root; PDL, periodontal ligament. Scale bar: 200 μm. Mean ± SD. n = 4–5. ∗ p < 0.05. ∗∗∗ p < 0.001. (M) Immunofluorescent images of COX-2 and IL-6 in alveolar bone of the older rats in control group, L-Vib group and H-Vib group. Scale bar: 100 μm. (N) WB results showed that the protein expression levels of COX-2 and IL-6 of the older rats in H-Vib group were higher than those in control group and L-Vib group. Mean ± SD. n = 3. ∗ p < 0.05. ∗∗ p < 0.01. Statistical significance was determined using the one-way ANOVA.
Article Snippet: The serum levels of CTX-1 and PINP in the rats were quantified using ELISA kits (CUSABIO, CSB-E12776r, CSB-E12774r).
