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

Figure 2

Continuous display of gastric laser Doppler blood perfusion image of rats during Acupuncture. Before acupuncture, most gastric blood flow were displayed as blue and dark green on the image, the blood vessels did not break, with less blood perfusion in the periphery vessels. After acupuncture, the light green and yellow regions increased gradually, indicating that blood perfusion the moderate and small vessels increase. At 5 and 10 min of acupuncture, blood perfusion of the microcirculation increase too. After ceasing of acupuncture, the light green regions increase whole, the yellow and red ranges extended further, indicating that acupuncture induces more obvious vasodilation in the stomach. (2-1) Before acupuncture; (2-2) instant of acupuncture; (2-3) acupuncture for 5 min; (2-4) acupuncture for 10 min; (2-5) 5 min after ceasing acupuncture; (2-6) 10 min after ceasing acupuncture.
