Abstract:
OBJECTIVE:To observe the effect of electroacupuncture (EA) preconditioning at heart meridian acupoints on the contents of dopamine (DA) and 5-hydroxytryptamine (5-HT) in lateral hypothalamus area (LHA) and cerebellar fastigial nucleus (FN) in the rats with acute myocardial ischemia-reperfusion injury (MIRI), and explore the role and mechanism of LHA and FN in the effect of EA at heart meridian acupoints against acute MIRI.
METHODS:Sixty SD rats were randomly divided into a sham-operation group, a model group, an EA heart meridian group and an EA lung meridian group, 12 rats in each group, as well as an LHA plus heart meridian group (damage of bilateral LHA) and an FN plus heart meridian group (damage of bilateral FN), 6 rats in each one. Three days after nucleus destruction, EA was applied to "Shenmen" (HT 7) and "Tongli" (HT 5) in the EA heart meridian group, the LHA plus heart meridian group and the FN plus heart meridian group and EA was applied to "Taiyuan" (LU 9) and "Lieque" (LU 7) in the EA lung meridian group, with 1 V in stimulating voltage and 2 Hz in frequency, lasting 20 minutes each time, once a day, for consecutively 7 days before model replication. Except in the sham-operation group, MIRI rat models were duplicated by ligation of the left anterior descending branch of the coronary artery in the rest groups. Using Power lab physiological recorder, ST segment displacement value was recorded before modeling, 30 min after ligation and 120 min after reperfusion separately. The high performance liquid chromatography-electrochemical detection and analysis system was adopted to determine the contents of DA and 5-HT in LHA and FN dialysate after rat modeling in each group.
RESULTS:In comparison of ST segment displacement value 30 min after ligation and 120 min after reperfusion among groups, the value in the model group was higher than that in the sham-operation group (
CONCLUSION:EA preconditioning at heart meridian acupoints can effectively alleviate myocardial injury in acute MIRI rats, during which, DA and 5-HT in LHA and FN may be the important material basis.
