Figure 2. Effects of capsaicin on twitch contractions elicited by electrical stimulation (30 μs, 20 V) of the vagus nerve.

Figure 2

A, representative traces showing twitch contractions mediated by vagal stimulation applied every minute, and the effect of capsaicin (3 × 10−5 M for 10 min) on the twitch contractions. The tissue was then washed with PSS for 3 min. After the removal of capsaicin, the twitch contractions recovered to the control level. B, summary plot of the inhibitory effect of capsaicin (3 × 10−7 to 3 × 10−4 M) on twitch contractions. Each data point represents the mean ± S.E.M. of four experiments.
