Table 2.

Rate constant of SO₄²⁻ uptake and amount of SO₄²⁻ trapped in RBCs left untreated (control) and RBCs treated as indicated. Results are presented as means ± S.E.M. from separate (n) experiments, where ns indicates not statistically significant versus left untreated or 10 µM HgCl₂; ** p < 0.01; *** p < 0.001 versus control; °° p < 0.01 or °°° p < 0.001 versus 10 µM HgCl₂, one-way ANOVA followed by Bonferroni’s multiple comparison post-hoc test.
