... technique. The greatest decrease in pHi was observed after addition of 5-( N -ethyl- N -isobutyl)-amiloride (MIA), an inhibitor of Na + /H + exchange. Na + /H + exchange was active under steady-state conditions at an extracellular pH of 7.4, and activity increased after intracellular acidification...

... . Under normoxic conditions, the pHi of goldfish hepatocytes was regulated by a Na + /H + exchanger and a Na + -independent Cl – /HCO 3 – exchanger, the latter being activated only after acidification of the cells. Mechanisms of acid secretion appear to be fuelled, at least in part, by lactate formation...
