Investigation of Hepatic Blood Perfusion by Laser Speckle Imaging and Changes of Hepatic Vasoactive Substances in Mice after Electroacupuncture
Figure 2
Hepatic LSP images before and after EA at nonacupoint. (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 increased while the light green and yellow areas gradually reduced and almost disappeared.
