摘　　要：在乌拉坦－氯醛糖麻醉的40只家兔上，观察了胸髓蛛网膜下腔微量注射去甲肾上腺素（NA，40ug／20ml）对电针“内关”效应的影响。结果表明：（1）电针“内关”可显著促进急性心肌缺血（AMI）后ST段、T波及血压的恢复；（2）NA可明显加快AMI后ST、T的恢复；（3）NA能明显加强电针“内关”促进ST、T恢复的作用；从而表明胸髓内α受体参与电针“内关”改善AMI的作用，提示胸髓上段是内关—心脏相关联系的环节之一。Influence of thoracic spinal subarachnoid microinjection of noradrenaline (NA, 40mg/20ul) on the effect of electroacupuncture (EA) at Neiguan (PC6) was observed in 40 rabbits anesthetized with urethan-chloralose. Results showed that: 1) EA of Neiguan (PC6) could significantly accelerate the recovery of ST - segment and T-wave of electrocardiogram induced by acute myocardial ischemia (AMI); 2 ). Subarachnoid microinjection of NA also could promote the recovery of ST, T and blood pressure of post-AMI; and 3) Subarachnoid microinjection of NA could strengthen the effect of EA of Neiguan (PC6) to promote the reocvery of ST and T of Post-AMI. It suggests that a-receptors of intra-thoracic spinal cord participate in the action of EA of Neiguan (PC6) ameliorating AMI, and the upper thoracic segement is one of the links fqr connecting Neiguan and the heart
