A: bradykinin (BK) dose-dependently suppressed myocardial oxygen consumption (MV̇o₂) in rats fed a normal diet, which was absent in rats in the HF-30D group, but it was restored by apocynin (APO) (n = 6 in each group). B: significantly greater vascular superoxide production in the HF-30D group than in the normal-diet group (n = 5 in each groups). C: APO-dependent normalization of SSID in arterioles of rats in the HF-30D group (n = 6). *Significant difference from normal-diet control animals. #Significant difference from the HF-30D group. +Significant difference between two curves.
