Acupuncture at heterotopic acupoints enhances jejunal motility in constipated and diarrheic rats

Figure 5 Effect of capsaicin on the regulation of jejunal motility by manual acupuncture at ST37. A: Representative traces of jejunal motility without and with capsaicin; B: Capsaicin significantly inhibited the increase in intrajejunal pressure caused by acupuncture at ST37 (^aP < 0.05 vs baseline, unpaired t-test, n = 20). Intrajejunal pressure was normalized by baseline, shown as the dashed line; C: Capsaicin showed no effect on ST37 acupuncture-mediated regulation of frequency of jejunal motility (unpaired t-test, n = 20). The frequency was normalized by baseline, shown as the dashed line.
