Characterization of endothelium-dependent relaxations to CJF in porcine coronary artery rings. Representative original tracing (a), corresponding cumulative data (b). The relaxation response is expressed as the percentage relaxation of the U46619-induced contraction. Effect of CJF on contractile responses (c). As indicated, intact rings were exposed to CJF (30 μg/mL) 30 min before the addition of increasing concentrations of U46619. Results are shown as means ± SEM (n = 7). ^∗ P < 0.05, ^∗∗ P < 0.01, ^∗∗∗ P < 0.001, significant difference versus rings without endothelium (b) or control (c).
