Enhancement of the cyclic motor activity of the ovine small intestine by lysergic acid derivatives. Mechanism and significance.

abstract：:Five carboxyl-terminal fragments of secretin ranging in size from 6 to 21 amino acid residues were tested for pancreatic secretory activity in the rat. None of the fragments displayed activity when given alone but each displayed significant activity when given after secretin. This apparent activity was shown to be the...
