Figure 4

Using the in-vitro calibration curve generated from known MMP catalytic activity as shown in Figure 1, interstitial MMP activity was computed at the midpoint of the myocardial arrest period and at the myocardial reperfusion period, prior to microdialysis probe removal. Interstitial MMP activity increased by over 6-fold with myocardial reperfusion.
