Myocardial infarct size after the 120-min reperfusion of the Langendorff-perfused rat hearts that were subjected to 60 or 180 min of global ischemia, sectioned, and stained with triphenyltetrazolium chloride. Infarct size in the hypothermia (A) and normothermia series (C). The data are presented as dot plots with median values. The triphenyltetrazolium chloride-stained heart slices selected from the representative experiments in each group in the hypothermia (B) and normothermia series (D). See Figure 1 for the group legends.
