Figure 2 (A) Periodic acid Schiff stained histological section from control region with normal wall motion. (B) Periodic acid Schiff stained histological section from reversibly dysfunctional myocardium. In both regions myocytes with glycogen accumulation (arrow) and myocytes appearing normal were observed. There was no apparent difference in glycogen content between regions. (C) Biopsy from irreversibly dysfunctional myocardium stained with picrosirius red. The degree of fibrosis (red) is increased, and the amount of myocytes (yellow) is reduced. (D) Biopsy from control region with normal wall motion stained with picrosirius red.
