Acidification of the gill cells of the shore crabCarcinus mediterraneus: Its physiological significance
Helgoländer Meeresuntersuchungen volume 49, pages 709–713 (1995)
Abstract
In a preparation of isolated gills of the shore crabCarcinus mediterraneus perfused with dilute sea water (pH 8.1, 200 mM Na+) which was identical to the bathing solution of the gill, acidification of the collected perfusate was observed. Acidification was not affected by 10−4 M EIPA (5-[N-ethyl-N-isopropyl]amiloride), a strong inhibitor of Na+/H+ exchange. However, in the presence of 10−4 M acetazolamide, acidification was greatly blocked. The significant decrease of the acid load of the perfusate is considered to be a result of inhibition of the branchial intracellular carbonic anhydrase catalyzing the formation of H+ ions.
