From: Non-endothelial endothelin counteracts hypoxic vasodilation in porcine large coronary arteries
Effect of PEG-catalase and PEG-SOD on hypoxic vasodilation. (A) Effect of PEG-catalase (100 u/ml) on concentration-response curves for oxygen lowering and (B) Effect of PEG catalase (100 u/ml) on concentration-response curves for hydrogen peroxide. (C) Effect of PEG-SOD (70 u/ml) on concentration-response curves for oxygen lowering. Results are means ± SEM of 8 experiments. Differences were evaluated with two-way ANOVA followed by Bonferroni post-test: * P < 0.05, ** P < 0.01, ***P < 0.001 compared to control.
