[Study on effect of electroacupuncture on gastric ischemia-reperfusion by laser Doppler blood perfusion imaging].

OBJECTIVE

To observe effects of electroacupuncture (EA) on gastric blood perfusion and search for a study method reflecting changes of blood perfusion.

METHODS

On the basis of establishing a new gastric ischemia-reperfusion model which was made by ligature of gastric right artery, EA was given at "Zusanli" (ST 36) and the gastric blood perfusion images were displayed by a laser Doppler blood perfusion imager (LDPI), and effects of EA on gastric blood perfusion were analyzed.

RESULTS

(1) The image of the gastric ischemia-reperfusion is clear. The ischemic degree of the stomach in the EA group was lower than the control group within 30 min of ischemia, and recovery of blood flow after perfusion in the EA group was better than the control group; (2) at 25 min of ligature, there was a significant difference in changes of blood perfusion between the EA group [(-0.50 +/- 0.18) PU] and the control group [(-0.90 +/- 0.16) PU], P < 0.05.

CONCLUSION

EA can improve and promote gastric blood supply in the gastric ischemia-reperfusion model, which can be used for acupuncture and moxibustion experimental study.
