Investigation of Hepatic Blood Perfusion by Laser Speckle Imaging and Changes of Hepatic Vasoactive Substances in Mice after Electroacupuncture
Figure 1
Hepatic LSP images before and after EA at ST36. (a) Before acupuncture; (b) EA for 5 min; (c) EA for 10 min; (d) EA for 15 min; (e) EA for 20 min; (f) EA for 25 min; (g) EA for 30 min; (h) digital coded brightness image of mouse liver. Before EA, LSP on the hepatic surface was displayed as light green, yellow, and red on the image. After EA for 5 min, the red areas were increased on the image immediately. When EA time was prolonged, the red areas were further extended while the light green and yellow regions gradually decreased.
