Figure 6: SI decreased myocardial oxidative stress and iNOS expression but increased IκBα expression after I/R injury in ovariectomized rats. (a) Dihydroethidium (DHE) fluorescence staining of myocardium. (b) Lever of plasma MDA. ((c) and (d)) Expression of iNOS (c) and IκBα (d) in myocardium with western blotting after 24 h perfusion. Plots represent the mean ± SEM, . Statistical significance: , compared with OVS; compared with CMC.
