these data show that naloxone can promptly stimulate catecholamine release and concur with the view that lh release evoked by naloxone in vivo may be due to hypersecretion of lhrh and they further raise the possibility that norepinephrine and epinephrine released in the vicinity of peptidergic neurons in the poa-mbh may participate in lhrh hypersecretion .
