TRPV1 and ischemia: Due to the modifications observed in the relative density of the iNOS in the CS group (Figure 6), we propose that the activation of TRPV1 regulates this enzyme, because the increases observed during ischemia and during reperfusion were not different from those observed in ischemia and reperfusion in the control groups, and with CZ or in the ischemia of the CZ+CS group.
