H⁺-flux from stria vascularis; control, glucose-free, ouabain and bafilomycin. a Summary traces (N = 4) of time-controls during perfusion of control bath solution in the absence of any experimental agents. Boxes labeled C1 and C2 are the perfusion times from two separate reservoirs of bath solution (see Methods for composition). b Summary traces (N = 3) of glucose-free (0-glucose) perfusion. c Summary traces (N = 3) of ouabain (1 mM) perfusion. d Bar graphs of steady state effects of time-control, glucose-free, ouabain and bafilomycin (1 μM; N = 6) perfusion. *, P < 0.05; ns, not significant. a, b, c Traces are the vertical averages of N experiments conducted with identical time-course. Standard error bars are indicated only at intervals for clarity; boxes show duration of the experimental period
