Figure 3: Comparison of relaxation of colon segments induced by 50 mM IVA, acetic acid and propionic acid.

Figure 3:

Colonic segments were equilibrated in an organ bath. The segments were allowed to equilibrate at 1 g tension for 1 h before the addition of acetylcholine (10 μM). Initial IVA-induced relaxation of ACh-contracted segments was 68 ± 6% (n=13). After washout of IVA, ACh-contracted colon segments relaxed 50 ± 8% or 51 ± 8% in response to acetic acid (n=7) or propionic acid (n=6), respectively. Values are means±SEM; * indicates P<0.05
