K+- and H+- fluxes from stria vascularis; bumetanide and DIDS. a and c K+ flux; b and d H+ flux. a Summary traces (N = 7) of effect of perfusion of bumetanide (50 μM; bumet) on K+ flux from stria vascularis. b Summary traces (N = 6) of effect of perfusion of bumetanide (50 μM) on H+ flux from stria vascularis. c Concentration-response curve for bumetanide on K+ flux from stria vascularis fit by the Michaelis-Menton equation (N = 5–6). d Bar graph summaries of steady–state effects of bumetanide (50 μM; N = 6; Bumet) and DIDS (1 mM; N = 6) on H+ flux from stria vascularis. *, P < 0.05; ns, not significant. a, b: boxes show duration of the experimental period
