Are Primo Vessels (PVs) on the Surface of Gastrointestine Involved in Regulation of Gastric Motility Induced by Stimulating Acupoints ST36 or CV12?

<table>Electro-stimulation of PVs with different intensities by bipolar stainless-steel electrodes. Stimuli were given with different intensities from 1 to 19 mA, increments 2 mA, duration 2 ms, 20 Hz for 30 s. (a) A representative recording of the intragastric pressure under electro-stimulation of PVs with different intensities. (b) The intragastric pressure was not changed significantly by electro-stimulating PVs with different intensities from 1–19 mA (<i>n</i> = 11, <svg height="11.375" id="M26" style="vertical-align:-0.1638pt" version="1.1" viewbox="0 0 58.712502 11.375" width="58.712502" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
