Membrane damage with loss of function. A: integrity of the sarcolemma was assessed by permeation of Evans blue dye (EBD). Noninjured TAs did not show dye uptake into the fibers (left), whereas injured TAs did (right), indicating sarcolemma damage. B: the percentage of EBD-positive fibers (dashed line) is plotted against contractile function (solid line), as measured by maximal isometric tetanic tension (Po). EBD was found in a high percentage of fibers immediately after the injury, when Po dropped significantly from noninjured values. Minimal EBD was seen 21 days postinjury, when contractile function was fully restored.
