Evaluation of Influence of Acupuncture and Electro-Acupuncture for Blood Perfusion of Stomach by Laser Doppler Blood Perfusion Imaging

Figure 3

Continuous display of gastric laser Doppler blood perfusion image of rats during EA. Before EA, most gastric blood flow showed as blue and dark green on the image, with the large blood vessels showed shorter in yellow-red. After EA, the light green and yellow-red regions increased gradually, indicating that blood perfusion of the small vessels and microcirculation increased in dissimilar degrees. At 5 and 10 min of EA, the micro-vessels prolongated on the image. After ceasing of EA, the light green, yellow and red ranges extended further, indicating that EA induces more obvious dilation of vessels in the stomach. (3-1) Before EA; (3-2) instant of EA; (3-3) EA for 5 min; (3-4) EA for 10 min; (3-5) 5 min after ceasing EA; (3-6) 10 min after ceasing EA.
