Response of Local Nitric Oxide Release to Manual Acupuncture and Electrical Heat in Humans: Effects of Reinforcement Methods

Figure 3

Quantification of NO metabolites over lung meridian following electrical heat. Concentrations of total nitrite plus nitrate () along the lung (LU) meridian collected over acupoints, meridian lines without acupoint (MWOP), and nonmeridian control region (NMCR) during 20 min of electrical heating (the 1st biocapture, the left panel) and 20 min after heating (the 2nd biocapture, the right panel) in healthy volunteers. Electrical heat was performed on LU11 of one arm selected at random while the opposing arm served as control. concentrations in the biocapture solution (M, top) and efflux rate calculated over the surface area in contact with the biocapture solution over a 20 min duration (nmol/cm²20 min, bottom) over acupoints compared to MWOP and NMCR. Each bar represents the mean values and vertical bars represent SEM; , compared with unheated side; , compared with MWOP and NMCR; , compared with 1st biocapture.
