Evidence for apical Na+/H+ exchanger in bovine main pancreatic duct


The finding of a high Pco 2 in basally secreted pancreatic juice of man and dog raises the hypothesis of proton secretion from ductal epithelial cells presumably through a Na+/H+ exchanger. To test this possibility, H+ luminal secretion and Na+ movements were measuredin vitro on samples of bovine pancreatic ducts mounted in Ussing-type chambers. The rate of… (More)
