مستخلص: | Introduction.Postprandial intestinal hyperemia is a complex vascular response during nutrient absorption. Many mediators have been studied including enteric reflexes, GI hormones, and absorption-stimulated metabolic mediators such as pH and adenosine. We have shown that nitric oxide (NO) mediates premucosal arteriolar dilation during glucose absorption and that glucose-induced portal vein NO metabolite production requires adenosine A2b receptor activation. We hypothesize that Na+-linked absorption ofl-glutamine orl-glycine might also stimulate NO release in the enteroportal circulation via adenosine A2b receptors. |
