Influence of blockade of transient receptor potential vanilloid type 1 (TRPV1) in region of acupoints on manual acupuncture (MA) and electroacupuncture (EA) modulation of pressor reflexes induced by gastric distension (GD). Bars represent increases in mean arterial blood pressure (MAP) following GD. Values below each bar indicate baseline MAP values (means ± SE) before GD. A: sham acupuncture was conducted by inserting acupuncture needles into the P6 or P5–6 acupoints without manual or electrical stimulation for 30 min. The diagram above this panel displays the sites of the P5 and P6 acupoints (17). B: 5% DMSO was injected into P6 during MA. C: injection of iodoresiniferatoxin (Iodo-RTX; 0.1 mM) into P6 with MA treatment. D: injection of Iodo-RTX into P5–6 with EA treatment. *P < 0.05, after vs. before MA or EA; #P < 0.05, after vs. before microinjection into the acupoint. Labels E1–3 within bar histogram displayed in C represent original BP tracings of a rat shown in E, E1–3.
