Display of Laser Doppler Perfusion Imaging (LDPI) for stomach blood flow in ischemia-reperfusion

Objective: To continuously display the images of stomach blood flow in ischemia-reperfusion, in order to research supplier for stomach blood flow, and to evaluate the application value of the Laser Doppler perfusion imaging (LDPI) , the new medicinal image technique, on the measure of entrails blood circulation. Methods: During the right gastricartery was clamped, the image of blood flow perfusion of stomach was displayed in the rat by LDPI, and change of blood circulation was analyzed. Results (1) In the nature state the blood flow perfusion images of the stomach are clear. LDPI image of stomach shows in flabellate distribution of blood vessel from lesser curvature to greater curvature of stomach. (2) After clamped the right gastricartery, the blood flow perfusion is going down markedly on the LDPI images, and last out loosened artery. (3) After loosened artery, the blood flow flare up to increase, and is paranormal. During 10min to 30min loosened artery the blood flow come back to normal. Conclusions: The model of ischemia-reperfusion is came into being by clamping the right gastricartery, the blood flow perfusion of the entrails could be displayed in imaging by LDPI.
