...Khaled H. Ahmed; Bernd Pelster; Gerhard Krumschnabel SUMMARY In trout hepatocytes, hypertonicity and cytosolic acidification are known to stimulate Na + /H + exchanger (NHE) activity, which contributes to recovery of cell volume and intracellular pH (pHi),respectively. The present study...

... 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...

...GREGORY A. AHEARN; PIERETTE FRANCO Purified brush-border membrane vesicles (BBMV) of starfish ( Pycnopodia helianthoides ) pyloric caecal epithelium were prepared by a magnesium precipitation technique in order to compare the properties of Na + /H + exchange in this invertebrate tissue with those...

...ANDREW R. COSSINS; ROBERT V. KILBEY A pH-stat method is described for determining the initial rate of efflux of H + equivalents from trout erythrocytes after stimulation with catecholamines. This measure of transport capacity of the Na + /H + exchanger was sensitive to medium pH with a peak at 7.24...

... + , providing evidence for a Na + /H + exchange with a stoichiometry of 1. The steady state following stimulation with adrenalin could be disturbed by changes in extracellular pH. After the addition of adrenalin, intracellular pH (pH i ) was increased by 0.2-0.3 units but did not exceed extracellular pH...
