(B) Absolute macrophage count calculated from a differential count determined in cytospin preparations stained with Diff-Quik stain. **P < 0.001, Tukey's test compared with the control group. ##P < 0.001, Tukey's test compared with the injury group. ξP < 0.05 Tukey's test compared with the 50 mW low-level laser therapy group.
