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

Figure 4 Effect of cobra venom on the regulation of jejunal motility by manual acupuncture at ST37. A: Representative traces of jejunal motility without and with cobra venom; B: Cobra venom did not inhibit the improved intrajejunal pressure caused by acupuncture at ST37 (unpaired t-test, n = 20). Intrajejunal pressure was normalized by baseline, shown as the dashed line; C: Cobra venom had no effect on ST37 acupuncture-mediated regulation of frequency of jejunal motility (unpaired t-test, n = 20). Frequency was normalized by baseline, as denoted by the dashed line.
