2 Fig. 1 Gracilis artery blood flow during reperfusion. Results reflect mean ± standard error of 10 muscles in each group.

4 Fig. 3 Electron micrograph of normal control muscle. Glycogen granules (G) are present, myofibrils show normal structure and are in an orderly pattern, and the mitochondria (M) are normal in size and electron-dense with intact membranes (arrow).

5 Fig. 4 Electron micrograph of gracilis muscle after 6 hours of ischemia and reperfusion. There is extensive intercellular edema (open squares) and myofibrillar disorganization and cytoplasm is depleted of glycogen. Mitochondria (M) are swollen with lysis of cristae (arrowhead) and the outer mitochondrial membrane has ruptured in some (arrow). (Original magnification × 14,300.)
