Effect of NaHS (10−2 mol·L−1at the serosal side; arrow) in the presence of mucosal glibenclamide (5 × 10−4 mol·L−1, A) or serosal glibenclamide (10−3 mol·L−1, C). (B and D) Results from the control experiments performed in parallel in the absence of glibenclamide. Values are means (symbols) ± SEM (lines), n= 7–9. For statistics, see Table 1. Isc, short-circuit current.
