Effect of inhibitors of
H2O2 production on the ion fluxes induced by
hypoosmotic stress. Aliquots of cell suspension were treated by IDP
(A–C, Hypo-IDP and Iso-IDP) or glucosamine (D, Hypo-Gl and Iso-Gl) as
described in the legend of Figure 2 for each of the inhibitors, except
the replacement of 10 mm by 1 mm Mes-Tris, pH
5.2, for the pH measurement experiments. Means ± se
of at least two independent experiments are reported in each case. FW,
Fresh weight.
