Figure 6. Effect of superfusion of the coeliac plexus with ODQ on the gastroduodenal inhibitory reflex.

Figure 6

All recordings were obtained from the same preparation. In the presence of Krebs solution, gastric distension produced a slight gastroduodenal inhibitory reflex (P ≤ 0.05) (A). When the coeliac plexus was superfused with L-arginine (2.5 × 10−5 M), gastric distension elicited a significant (P ≤ 0.001), long-lasting (28 min) decrease in the amplitude of duodenal contractions after a 1 min latency period (B). When the coeliac plexus was superfused with L-arginine (2.5 × 10−5 M) + ODQ (2.5 × 10−6 M), gastric distension failed to produce a gastroduodenal inhibitory reflex (C).
