Effectiveness of Gastric Electrical Stimulation is Related with Regional Expression Of Interstitial Cells of Cajal in Porcine Stomach

Aims Stomach is composed with several types of interstitial cells of Cajal (ICC). Among ICCs, myenteric ICC (ICC-MY) serve as a pacemaker which creates the bioelelctrical slow wave potential that leads to contraction of the smooth muscle. Moreover, the ICC-MY responses to an external electrical stimulation. We performed to investigate a proper electrical parameter to cause resonance of contraction of muscle.
