Effect of feeding on the cessation of transport of macromolecules by enterocytes of neonatal piglet intestine.
To elucidate further the role of digesta in the cessation of transport of macromolecules to the blood by enterocytes of neonatal piglet small intestine, a portion of the ileum was surgically isolated and vented to the exterior. The ability of this isolated intestine to transport macromolecules was compared with that of the intestine remaining in the digestive pathway in the same piglet. The isolated intestine ceased transporting macromolecules at the same time as the intestine in the digestive pathway, thus implicating a humoral signal that is responsible for the cessation of transport.
