Arginine Vasopressin Injected into the Dorsal Motor Nucleus of the Vagus Inhibits Gastric Motility in Rats

Figure 5

Effects of AVP (180 pmol) on gastric motility with pretreatment of SR49059 (320 pmol) or Hexamethonium (8 μmol). Mean data of total duration (a) and total amplitude (b) and motility index (c) before microinjection and after microinjection 0–5 min, 5–10 min, and 10–15 min. Average inhibitory rate of total duration, total amplitude, and motility index before and after microinjection of SR49059 (d) and Hexamethonium (e). and , versus before microinjection.
