Comparison of PCNA and VEGF immunohistochemistry between Ctrl, Ctrl_V, DM, and DM_V groups (n = 6/timpoint). (A) VEGF of DM_V rats were significantly higher than those of DM rats at Days 8 and 13 post wounding. VEGF of Ctrl_V rats were significantly higher than those of Ctrl rats at Days 4, 8, and 13 post wounding. (B) Comparing between vibration groups, VEGF of Ctrl_V rats was significantly higher than those of DM_V rats at Day 1. (C) PCNA of DM_V rats were significantly higher than those of DM rats at Days 8 and 13. PCNA on Ctrl_V rats was significantly higher than those of Ctrl rats at Day 8. **Significant difference. Note: Arrows indicate PCNA and VEGF expressions.
