Abstract:
Objective To compare the skin temperature around relevant and irrelevant meridian acu-points,or non-meridian sham acupoints in rats with myocardial ischemia by high frequency electro-acu-puncture(EA)at Neiguan(PC6)point or sham acupoint,in healthy rats and myocardial ischemic rats. Methods Fifty male Wister rats were randomly divided into five groups:blank control group,sham-op-eration group,model group,high frequency EA at Neiguan group(PC6)and high frequency electro-acu-puncture at sham acupoint groups.Rats in high frequency EA at and at sham acupoints group received EA intervention after their models were successfully established.Temperature around the skin of Neiguan (PC6),Yanglingquan(GB34)and sham acupoints were measured and recorded by infrared thermogra-phy in every group at 30 minutes 60 minutes after three-day treatment for statistical analysis.Results Compared with the blank control group,skin temperature around PC6 in model groups was significantly lower(P<0.01);Compared with the model group,skin temperature around PC6 in high frequency EA at PC6 group was significantly increased(P <0.01);Skin temperature around PC6, GB34 and sham acupoint in high frequency EA at sham acupoint groups presented with no statistical significance; skin temperature around PC6 in high frequency EA at PC6 group was similar to the skin temperature of blank control group,which was measured 30 minutes after the treatment.Conclusion The relative specificity of skin temperature around PC6 can be useful for the reflection of different conditions of rats' myocardi-um.High-frequency electro-acupuncture at PC6 can prevent the reduction of skin temperature caused by myocardial ischemia injury,of which the mechanism needs further study.
