Figure 1.
Effect of pistachios on infarct size and area at risk. In STZ-ischemia-reperfusion rats, myocardial ischemia/ reperfusion resulted in significantly increased infarct size (B) when compared with sham-operated animals in (A). Blue stained region indicates non-ischemic, normal region; red-stained region indicates ischemic/reperfused but not infarcted region; and negative-stained region indicates ischemic/reperfused infarcted region. NP caused a significant reduction in myocardial infarct size when compared with vehicle-treated animals (C). The effect of NP was higher compared with RP (D). Quantification of myocardial infarct size expressed as percentage (E) and as percentage of area-at-risk(AAR) (F). Data are means ± S.E.M. of 10 rats for each group. *P < 0.05 vs. sham, °P < 0.05 vs. ischemia-reperfusion.
