Figure 1 (A) A digital photograph of a representative nitro blue tetrazolium-stained heart slice (top left), a color-contrasted version to highlight the infarcted regions (top right), and an outline of the planimetered infarct area for infarct sizing (bottom). (B) Mean left ventricular developed pressures (LVDPs) (% pre-ischemic values) at 5 to 30 min of reperfusion after 25 min of global ischemia of hearts treated with cytoskeletal specific immunoliposomes (CSIL) at 1 min of ischemia (CSIL 1') (squares), PBS (open circles), or sham-instrumented hearts (solid circles). (C) Representative digital photographs of nitro blue tetrazolium-stained mid-slices of normal hearts (a) or hearts treated with CSIL 1' (b) or PBS (c).
