Figure 7.
Hemotoxylin and Eosin stained healthy control muscle (A), apparently unaffected muscle from the λ-carrageenan injected limb (B), and inflamed skeletal muscle (C,D). The healthy muscle in panel A has angular fibers, minimal spacing between fibers, and a low number of infiltrating cells. Panel B shows muscle from the injected limb that does not appear to be inflamed. Panels C and D show regions of inflamed muscle tissue; note the swollen, round appearance of the fibers, the increased interstitial space, and the numerous leukocytes migrating into the region.
