Figure 2: Myocardial infarct size in Sham-operated rats or in rats subjected to 30 min ischemia followed by 2 h of reperfusion. The blue-stained areas represent nonischemic tissue, and red-stained areas represent the area at risk. Pale areas indicate infarct areas. Values presented are mean ± SEM. AAR: area at risk; IA: infarct area; I/R: ischemia/reperfusion; SFI: Shen-fu injection; WOR: wortmannin. , * versus Sham,# versus I/R, and α versus SFI.
