Each value represents mean ± sem, n = 5 in treatment group and n = 10 in control and morphine treated group.

^* prokinetic agents were given 45 minutes and morphine 15 minutes prior to the test meal.

^aP < 0.05 and

^bP < 0.001 vs control group.

^cP < 0.05 and

^dP < 0.001 vs morphine treated group.
