Figure 5

Effect of propionylcholine (500 μM on the serosal side; upper row) or butyrylcholine (500 μM =on the serosal side; lower row) in the absence (left column) or presence (right column) of tetrodotoxin (1 μM at the serosal side). Values are given as means (black symbols) ± SEM (grey area), n = 6. Line interruptions are caused by omission of time intervals in order to synchronize the tracings of individual records to the administration of the respective agonist. BCh, butyrylcholine; PCh, propionylcholine; TTX, tetrodotoxin.
