Figure 1.
Confirmation of reperfusion with injection of Evans blue dye in the absence of ligation (A, B), after 4 h of persistent ligation (C, D), and after 4 h of transient ligation followed by reperfusion for 24 h (E, F). In each case, the heart was visualized before (left panels) and after injection of the dye. As can be seen, dye did not appear in nonreperfused regions (D) but did after 24 h of reperfusion (F). White regions in E and F are reflections from fat.
