Regulation of intestinal blood flow.
The gastrointestinal system anatomically is positioned to perform two distinct functions: to digest and absorb ingested nutrients and to sustain barrier function to prevent transepithelial migration of bacteria and antigens. Alterations in these basic functions contribute to a variety of clinical scenarios. These primary functions intrinsically require splanchnic blood flow at both the macrovas...
متن کاملMorphine-neural interactions on canine intestinal absorption and blood flow.
Intestinal Na and H2O fluxes and blood flow were determined in extrinsically denervated or innervated ileum of fed dogs during intra-arterial (0.2, 2, 20 micrograms min-1) or intraluminal (4, 40, 400 micrograms ml-1) morphine sulphate infusion. 3H2O and 22Na were used to determine unidirectional fluxes and 3H2O clearances were used to determine total segmental and absorptive site blood flow. Ne...
متن کاملIntestinal villus blood flow measured with carbon monoxide and microspheres.
The purpose of the present study was to compare the small intestinal blood flow that equilibrates with luminal CO (FLco) with simultaneous determinations of villus blood flow measured by a recent modification of the microsphere technique. These studies, carried out in rabbits, showed that FLco closely correlated (r = 0.83) with villus flow measured with microspheres over a three-fold range of f...
متن کاملIntestinal tissue blood flow in shock due to endotoxin.
THE SMALL intestine has been implicated in irreversible shock due to endotoxin and hemorrhage by both clinical and experimental observations. Penner and Bernheim in 1939 described the pathology of the small intestine in shock that occurs clinically. They stated that there first appeared congestion, edema and hemorrhage in the submucosa with hemorrhagie necrosis of the mucosa as a later manifest...
