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

Figure 2 Effects of manual acupuncture at LI11, ST37, ST25, and BL25 on jejunal motility in constipated rats. A: A representative trace of jejunal motility in a constipated rat; B: Representative traces of jejunal motility regulated by acupuncture at LI11, ST37, ST25, and BL25 in constipated rats; C: Intrajejunal pressure was enhanced by acupuncture at LI11 or ST37 but reduced by acupuncture at ST25 (^aP < 0.05, ^bP < 0.01 vs pre-acupuncture, paired t-test, n = 17); D: Only acupuncture at ST25 decreased the frequency of jejunal motility (^aP < 0.05 vs pre-acupuncture, paired t-test, n = 17); E: The percent change in intrajejunal pressure caused by acupuncture at LI11, ST37, ST25, and BL25 (^cP < 0.05, ^dP < 0.01 vs baseline, paired t-test, n = 17). The intrajejunal pressure was normalized by baseline, which is denoted by the dashed line.
