Figure 1From: Effect of low-level laser therapy on the expression of inflammatory mediators and on neutrophils and macrophages in acute joint inflammationAnalysis of the articular lavage 24 hours after induced papain injury. (A) Absolute neutrophil count calculated from a differential count determined in cytospin preparations stained with the Diff-Quik stain. *P < 0.05 and **P < 0.001, Tukey's test compared with the control group. ##P < 0.001, Tukey's test compared with the injury group. (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. Results expressed as mean ± standard error of the mean. LAS: Washed Articular Synovium.Back to article page
