Figure 7 Time course of the amplitude inhibited by thienorphine (100 μmol/L), buprenorphine (100 μmol/L), morphine (3. 2 mmol/L) or naloxone (1.0 mmol/L) on guinea-pig ileum contraction induced by Ach (1 μmol/L) during the prolonged washing process. The data are expressed as % amplitude with respect to the amplitude before chemical application, and each point represents the mean ± SE (n = 4). Thie: Thienorphine; Bup: Buprenorphine; Mor: Morphine; NLX: Naloxone.
