The postacupuncture infusion of norepinephrine (NE) into the PVN diminished the inhibitory effect of acupuncture on EW-induced oversecretion of plasma corticosterone. Data are expressed as mean ± standard error of the mean of the levels of plasma corticosterone. **p < 0.01, compared with saline-treated control group; ††p < 0.01, compared with EtOH-treated control group. EtOH = ethanol; EW = ethanol withdrawal; MRS = modified Ringer’s solution; PVN = paraventricular nucleus; ST36 = acupuncture at the acupoint ST36; Tail = acupuncture at the nonacupoint located in the tail.
