Figure 4

S-T maps showing the effect caused by the serosal addition of NaHS (0.3 and 1 mM) on motor patterns observed in colonic segments in the presence of lidocaine (100 μM) (A) and lidocaine (100 μM) + carbachol (10 μM) (B). Note that in the presence of lidocaine alone, ripples but not RPMCs are observed. Addition of carbachol restored RPMCs. Detail of the diameter of the colon in the proximal region in control conditions (Aa) and after the addition of NaHS (1 mM) (Ab) (dotted lines in S-T maps) in the presence of lidocaine (100 μM). Detail of the diameter of the colon in the proximal region in control conditions (Bc) and after the addition of NaHS (0.3 mM) (Bd) (dotted lines in S-T maps) in the presence of lidocaine (100 μM) + carbachol (10 μM). In both cases, NaHS caused effects similar to those observed in control conditions.
