Figure 1.

Inhibitory effects of NC (a), mean±s.e. mean, (n = 6–9) and EM1 (b), mean±s.e. mean, (n = 11–16) in the absence and presence of peptidase inhibitors (PI) on electrically stimulated hVD. In panel (c) the effect of [F/G] (10 µm) and naloxone (1 µm) on the inhibitory effect of NC (▪) and EM1 (□) (both 1 µm) are shown. Data in (c) are from n ≥ 3 (mean±s.e. mean) except for naloxone vs NC where the mean of 2 determinations showing no inhibition are given.
