Fig. 4. Secreted fluid pH and concentrations of K+, Na+ and
Cl– before (open bars) and after (solid bars) the addition of
10 µmol l–1 Tenmo-ADFb (ADFb), 1 nmol l–1
Achdo-KII (AKII) and 1 mmol l–1 8-bromo cyclic GMP (cGMP).
Bars represent the means + 1 s.e.m. for the number of replicates shown in
parentheses. Asterisks indicate where the change in composition following
addition of the secretagogue is significant in a paired t-test;
*P<0.05; **P<0.01;
***P<0.001.
