Effects of intra-arterially infused adenosine triphosphate (ATP) on release of vasoactive intestinal polypeptide (VIP) from the gastrointestinal tract of the cat.
Sjöqvist A, Fahrenkrug J, Hemlin M, Jodal M, Lundgren O. Sjöqvist A, et al. Acta Physiol Scand. 1985 Dec;125(4):693-8. doi: 10.1111/j.1748-1716.1985.tb07772.x. Acta Physiol Scand. 1985. PMID: 4091009
Close i.a. infusions of ATP were made to the stomach, the small intestine or the colon in the cat. The vascular reactions were followed by recording arterial pressure and total venous outflow continuously and the release of VIP was estimated intermittently from arterio-ven …
