Figure 3: Distribution of pro-inflammatory macrophages after mild muscle injury and injury size comparison (IMAGE)
Caption
Top left: Cross-sections of muscles from animals given either no treatment or icing treatment after mild muscle injury. Comparison of inflammatory macrophage distribution (indicated by white arrowheads) from 1 day after injury through to 3 days after injury. On day 1 and day 3 in the icing group, hardly any pro-inflammatory macrophages accumulated in the injury site. Bottom left: Number of pro-inflammatory macrophages in the field of view. There were few inflammatory macrophages at the site of injury if icing was carried out. Top right: Injury size comparison. The percentage of total myofiber area taken up by injured fibers was compared. Expansion of injury was not found in muscle from the icing group (black bars). Bottom right: Schematic diagrams of the phenomena occurring inside untreated injured muscles and injured muscles given an icing treatment.
