Representative tracings of the Isc response of rat jejunum to the serosal addition of (A) SL-NH2 (20 μM) and LS-NH2 (80 μM), when tissues were bathed in normal Krebs buffer, or SL-NH2 (80 μM) in tissues bathed with chloride- (Cl−) free Krebs buffer. (B) tc-NH2 (40 μM) and trypsin (10 and 50 units/ml; 20 and 100 nM) in normal Krebs buffer. (C) Cit-NH2 (20 and 100 μM) and thrombin (5 units/ml; 50 nM) in normal Krebs buffer. (D) SL-NH2 (80 μM) after trypsin (100 units/ml; 200 nM), and trypsin alone (100 units/ml; 200 nM), followed by carbachol (Cch, 1 μM) in normal Krebs buffer. The scale for time and Δ Isc (in μA/cm2) is shown respectively to the right and to the left of each tracing. All panels show a tracing for an individual tissue preparation that is representative of six independently conducted experiments.
