Cardioprotective effect of Etpost from Potentilla reptans root. Representative photographs of TTC (2,3,5-triphenyl-tetrazolium chloride) stained rat heart sections and statistical data of myocardial infarct size (IS/AAR%) and area at risk (AAR/LV%) in the isolated perfused rat hearts subjected to IR, IPOST, Etpost (2 μg/ml), IPOST + inhibitors, Etpost + inhibitors. Data are presented as means ± SEM and expressed in percentages. *P < 0.05 vs. IR; ^& P < 0.05 vs. IPOST; ^# P < 0.05 vs. Etpost (2 μg/ml); ^$ P < 0.05 vs. IPOST+ inhibitor. (LV: Left ventricular, Etpost: ethyl acetate fraction of P. reptans root at postconditioning mechanism)
