An examination of 5-hydroxytryptamine receptors in human saphenous vein.

abstract：:In perfused rabbit adrenal glands, colchicine (500 muM) inhibited the catecholamine secretion evoked by acetylcholine (20 mug/ml) but not that evoked by excess potassium (60 mM). Since both stimuli are believed to release catecholamines ultimately by the same secretory process, exocytosis, it is concluded that these i...
