Fig. 6. Representative traces demonstrating the effects of propofol on the rate of recovery from intracellular acidosis after washout of NH⁴Cl. (A ) 5-(N -ethyl-N -isopropyl)-amiloride (EIPA) abolished the recovery from intracellular acidosis induced by washout of NH⁴CI. (B ) Propofol (30 μm) attenuated the magnitude of the NH⁴CI acidosis and increased the rate of recovery. (C ) Data are normalized to peak acidosis values to illustrate the effect of propofol on rate of recovery.
