[Effects of mescaline and lysergide on the mechanical responses of isolated organs of the rat to catecholamines and the role of calcium transfers in these phenomena].
On isolated Rat vas deferens the contracting responses of noradrenaline and dopamine are increased by mescaline (23 micromoles) and decreased by lysergide (15 micromoles). Similarly, on isolated Rat duodenum previously decalcified the hypertonic responses of recalcification are modified in the opposite direction by the two agonists. On the other hand, mescaline such as lysergide increase the fall of tonus which ensues the decalcification of isolated duodenum.
