Gentle Manual Acupuncture Could Better Regulate Gastric Motility and Vagal Afferent Nerve Discharge of Rats with Gastric Hypomotility

Figure 3

Responses of gastric motility and gastric vagal afferent fiber discharge due to atropine and MA treatment with different frequencies (2 Hz and 4 Hz) at ST36. (a, b) Examples of the alterations of gastric motility and gastric vagal afferent fiber discharge induced by atropine and MA stimulations with different frequencies (2 and 4 Hz) at ST36. In each panel, the top trace is the wave of gastric motility, the middle trace is the action potentials of the gastric vagal afferent fibers, and the bottom trace represents the PSTH (1 s bin width). (c, d) Changes in the gastric motility and vagal afferent fibers after the atropine injection and MA stimulation at ST36 (normal, model, 2 Hz, and 4 Hz, and n = 5, respectively; versus the normal group at the indicated time point; versus the atropine group at the indicated time point; ※ versus the 4 Hz group after modeling).
