Measurements of Location-Dependent Nitric Oxide Levels on Skin Surface in relation to Acupuncture Point
Figure 1
Schematic illustration for the points on the skin where a NO microsensor was positioned for pNO measurement: (a) at LI4 acupuncture point (solid circle) and non-acupuncture point (open circle); (b) 10 points along one-dimensional line on left wrist transverse crease; (c) at 25 different points within two-dimensional square area. The points, No. 1, 10 in (b) and the points, No. 1, 5 in (c) were positioned 5 mm apart from the left and right sides of the wrist. Symbol// represents the same separation.
