Participation of ROS in AngII-induced aortic constriction. A) AngII-induced aortic constriction in control rats (n=12) was reduced after pre-incubation with apocynin (300uM, n=7), B) MS rats showed similar AngII-induced constriction in the presence (n=5) or absence (n=12) of apocynin. C) AngII-induced aortic constriction in control rats (n=12) was reduced after pre-incubation with PEG-SOD (1000 Units/mL, n=6), D) MS rats (n=12) showed similar AngII-induced constriction using PEG-SOD. * p<0.05 vs. untreated.
