... and metabolite levels were measured in the peripheral skeletal muscle, normal myocardium, the infarct border zone, and the infarct interior. The diffusion coefficients of fluorescein or FITC-labeled dextran (0.3–70 kD) were measured in these tissues using fluorescence recovery after photobleaching. The vascular...
