The role of prostanoids in regulation of jejunal blood flow (JBF) was studied in anesthetized dogs. Intra-arterial infusions of arachidonate produced biphasic changes and dose-dependent decreases in jejunal vascular resistance (JVR) in untreated and aspirin-pretreated dogs, respectively; mefenamate abolished these responses. The jejunum released prostaglandin I2 (PGI2) greater than PGE2 greater than thromboxane A2 (TXA2) (radioimmunoassay) under resting conditions, and food enhanced the release… 
l‐NAME, nitric oxide and jejunal motility, blood flow and oxygen uptake in dogs
Inhibition of nitric oxide synthesis by l‐NAME increased jejunal motility and vascular resistance and the marked increase in motility can abolish or reverse the vasoconstriction.
Sympathetic, parasympathetic and enteric regulation of the gastrointestinal vasculature in rainbow trout (Oncorhynchus mykiss) under normal and postprandial conditions
It seems as though the enteric nervous system is essential to the regulation of the postprandial hyperemia, and that the extrinsic innervation is involved mainly in theregulation of gastrointestinal blood flow under normal conditions and in response to central coordination with other organs.
Effect of Diet on Changes in Small Intestinal Blood Flow Following Intracolonic Administration of Indomethacin to Rats
The hypothesis that the solid component of diet modulates small intestinal blood flow (SIBF) following indomethacin administration is tested and it is suggested that solid components of diet increase basal SIBF and decrease S IBF following indometrichac in both normal diet and liquid diet.
Regulation of intestinal blood flow.
The purpose of this review is to summarize the current understanding regarding the regulatory mechanisms of intestinal blood flow in fasted and fed conditions and during pathological stress.
Physiologic hypoxia and oxygen homeostasis in the healthy intestine. A Review in the Theme: Cellular Responses to Hypoxia.
The principles of mucosal oxygen delivery, metabolism, and end-point functional responses that result from this unique oxygenation profile are reviewed.
Developmental expression of eNOS in postnatal swine mesenteric artery.
It is concluded that the expression of eNOS changes within the mesenteric artery during early postnatal development at a posttranscriptional level is concluded.
