Time course of SO₄⁼ uptake measured in untreated erythrocytes (ctr) and in erythrocytes treated with 1 µM Mel + 300 µM H₂O₂ with or without pre-exposure to 50 mM 3-AT. *** p < 0.001 vs. ctr; 50 mM 3-AT + 300 µM H₂O₂ ^°°° p < 0.001 vs. 300 µM H₂O₂; 1 µM Mel + 50 mM 3-AT + 300 µM H₂O₂ n.s. not significant vs. 50 mM 3-AT + 300 µM H₂O₂ as determined by one way ANOVA followed by Bonferroni’s post hoc test (N = 8).
