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

Figure 1 Jejunal motility regulated by manual acupuncture at LI11, ST37, ST25, and BL25 in normal rats. A: A representative trace of jejunal motility in normal rat; B: Representative traces of jejunal motility regulated by acupuncture at LI11, ST37, ST25, and BL25; C: Acupuncture at LI11, ST37, and ST25 affected intrajejunal pressure significantly in normal rats (^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 (^bP < 0.01 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). Intrajejunal pressure was normalized by baseline, which is denoted by the dashed line.
