  • Values represent means ± SEM of three to five animals. Intragastric pressure (IGP) is expressed as percentage change from baseline. Fundic activity (Fundus) is expressed in terms of change in gram tension.

  • F3-a  p < 0.05 using ANOVA followed by Duncan's, as compared with data tabulated in Tables1 and 2 obtained with first dose of nicotine in vagus nerve intact animals.
