Figure 3.
Effect of preincubation with 1 µmol·L−1 phentolamine on the vasoconstrictor response induced by electric field stimulation (EFS) in mesenteric segments from control (A), high-fat diet (HFD) (B) and HFD + rosuvastatin (C) rats. (D) Vasoconstrictor response to exogenous noradrenaline in segments from control, HFD and HFD + rosuvastatin rats. Results (mean ± SEM) are expressed as a percentage of previous contraction elicited by KCl. n= 6–10 animals per group. *P < 0.05 versus conditions without specific inhibitor for each frequency (Bonferroni test).
