Figure 2. Effect of superfusion of the coeliac plexus with L-NOARG on the gastroduodenal inhibitory reflex.

Figure 2

A and B were obtained from the same preparation. Gastric distension (here and in the following figures, 50 ml for 5 min, indicated by the hatched columns) triggered a significant (P ≤ 0.001), long-lasting (22 min) decrease in the amplitude of duodenal contractions after a 7 min latency period (A). When the coeliac plexus was superfused with L-NOARG (10−5 M), the same gastric distension failed to produce the inhibitory response (B).
