Characteristics of Reactive Hyperemia in the Canine Intestine.
• Although many studies have dealt with postocclusion ("reactive") hyperemia in skeletal muscles," and a considerable number with such hyperemia in the coronary " and renal circulations," little systematic study of this phenomenon appears to have been made on the intestinal circulation. Since this vascular bed has received considerable attention in relation to intestinal ischemic shock," endoto...
متن کاملEffects of Endotoxin on the Hemodynamics of the Stomach
Endotoxin induces many profound vascular effects, including venous pooling, changes in resistance to blood flow in many organs, and circulatory collapse leading to death. Prominent among the early vascular effects of endotoxin is the rapid development of hepatic and intestinal congestion (2-4). One apparent mechanism of splanchnic blood pooling in endotoxin shock is hepatic venoconstriction. Li...

متن کاملControl of the Splanchnic Circulation 1
The major regulatory factors in the mesenteric circulation include general hemodynamic forces, the autonomic nervous system, circulating vasoactive substances, tissue metabolites and intrinsic characteristics of vascular smooth muscle. During mesenteric ischemic states smooth muscle spasm elevates resistance to blood flow and aggravates intestinal tissue hypoxia leading to mucosal necrosis. Clo...
متن کاملVascular stasis, intestinal hemorrhage, and heightened vascular permeability complicate acute portal hypertension in cd39-null mice.
Vasoactive factors that regulate splanchnic hemodynamics include nitric oxide, catecholamines, and possibly extracellular nucleosides/nucleotides (adenosine, ATP). CD39/ectonucleoside triphosphate diphosphohydrolase-1 (NTPDase1) is the major vascular ectonucleotidase that hydrolyzes extracellular nucleotides. CD39 activity may be modulated by vascular injury, inflammation, and altered oxygen te...
