2μl) in rostral ventrolateral medulla (rVLM) on the effect of electroacupuncture (EA) at Neiguan (PC 6) was observed in the rabbit with acute myocardial ischemia. Results showed that (1) EA of Neiguan could significantly accelerate the recovery of AMI-induced changes in ECG ST-segement
mean blood pressure
left ventricular pressure (LVP) and dp/dt rnax; (2) Clon strengthened the effect of EA on ST and LVP in some degree;and (3) Yoh significantly weakened the effect of EA on ST and LVP. lt reveals that when α2 receptors of rVLM are excited
the favourable effect of EA in regulating post-ischemic myocardial electrical and rnechanical activity can be enhanced in some degree; and when they are inhibited
the effect of EA disappears
indicating an involvement of α2 receptors of rVLM in EA of Neiguaninduced regulation on the functional activity of the heart.
