Figure 1. Spontaneous gastric contractions in sham-operated and vagotomized, fasted suncus.

Figure 1

(A) Regular, cyclic, spontaneous MMC with phase I, II, and III contractions was observed in the stomach of sham-operated suncus. (B) In vagotomized suncus, the amplitude of phase II contractions was decreased, although spontaneous MMC was also observed. Asterisks indicate the phase III contraction. (C) The entire period of the MMC and the duration of phase III were unchanged between sham and vagotomized suncus; however, the duration of phase I was increased in vagotomized suncus. In contrast, the duration of phase II was significantly shorter in vagotomized suncus than in sham-operated animals. (D) The motility index of phase II was significantly lower in vagotomized suncus than in sham-operated suncus. * Phase III contractions. #, p<0.05; ##, p<0.01; n = 5.
