    Adrenaline and isoproterenol elicited nearly maximal relaxation of the colon even in small doses, whereas increase in the doses caused greater relaxation in the duodenum. In the colon, these drugs prevented, to a great extent the contraction induced by acetylcholine (ACh) and serotonin but in the duodenum were totally ineffective. Dibenamine and propranolol reduced adrenaline- and isoproterenol-induced relaxation in the duodenum, though propranolol decreased the relaxation caused by isoproterenol. Atropine prevented ACh-induced contraction in both the colon and duodenum in the same way. After 2-bromolysergic acid diethylamide, duodenal contraction caused by ACh or serotonin decreased by over 70%; however, the contraction of the colon was not significantly inhibited. Methysergide had similar effects, but to a lesser degree. In calcium-free bathing fluid without addition of Na2EDTA, ACh and prostaglandin E1 elicited contraction in the colon, but not in the duodenum.
