Figure 8

Serum gastrin concentrations in surgically prepared animals superfused at different luminal pH values. Serum gastrin levels (pM) were measured via radioimmunoassay in anaesthetised animals treated for 1 h with carboxymethylcellulose (CMC; vehicle), omeprazole or famotidine, as indicated in the figure, then surgically prepared and superfused with pH 3 (△) or pH 7 (▲) luminal perfusates as in imaging experiments. Results from individual animals are shown as data points (n = 4 animals per group), with a horizontal bar indicating the mean value of each group. Significance was tested by two-way ANOVA.
