Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation of the gastrointestinal tract is under the control of both myogenic and metabolic regulatory systems. The myogenic mechanism contributes to basal vascular tone and the regulation of transmural pressure, while the metabolic mechanism is responsible for maintaining an appropriate balance between O2 demand and O2 delivery. In the postprandial state, hydrolytic products of food digestion elicit a hyperemia, which serves to meet the increased O2 demand of nutrient assimilation. Metabolically linked factors (e.g., tissue pO2, adenosine) are primarily responsible for this functional hyperemia. The fenestrated capillaries of the gastrointestinal mucosa are relatively permeable to small hydrolytic products of food digestion (e.g., glucose), yet restrict the transcapillary movement of larger molecules (e.g., albumin). This allows for the absorption of hydrolytic products of food digestion without compromising the oncotic pressure gradient governing transcapillary fluid movement and edema formation. The gastrointestinal microcirculation is also an important component of the mucosal defense system whose function is to prevent (and rapidly repair) inadvertent epithelial injury by potentially noxious constituents of chyme. Two pathological conditions in which the gastrointestinal circulation plays an important role are ischemia/reperfusion and chronic portal hypertension. Ischemia/reperfusion results in mucosal edema and disruption of the epithelium due, in part, to an inflammatory response (e.g., increase in capillary permeability to macromolecules and neutrophil infiltration). Chronic portal hypertension results in an increase in gastrointestinal blood flow due to an imbalance in vasodilator and vasoconstrictor influences on the microcirculation.

Available in PDF, EPUB and Kindle. Book excerpt: Dysfunction of the gastrointestinal tract in critically ill patients has recently become a focus of intensive research. This book, the first one on this topic, is a comprehensive overview of what is currently known about the role of the gut in patients requiring intensive care. The definitions and pathogenesis of intestinal dysfunction are critically evaluated. Currently available and potential new ways to monitor intestinal function in the intensive care setting are presented. Emphasis has been placed on the evaluation of therapeutic strategies in the prevention and treatment of gut dysfunction. Options for monitoring and treating gut dysfunction in critically ill patients are rapidly evolving. This volume provides state-of-the-art information for both clinicians and clinical researchers.

Available in PDF, EPUB and Kindle. Book excerpt: Gastric secretions contain hydrogen ions at a concentration that is more than one million times higher than their intracellular concentration. This phenomenal gradient as well as the demonstrated ability of gastric juice to digest tissues has motivated clinicians and investigators alike to emphasize acid secretion and acid ablation in studying the pathogenesis and therapy of peptic ulcer disease. Conse quently, over the past 150 years, we have made considerable progress in under standing the mechanisms and regulation of acid secretion by the stomach. Not surprisingly, therapy for both peptic disease and mucosal injury has also been predominantly directed at either neutralizing acid or suppressing its production. During the past 10 years, attention has been focused on factors other than acid in the genesis and therapy of ulcer disease. Work done worldwide demon strated that acid hypersecretion is not a common event in peptic ulcer disease. Therefore, we began realizing that factors other than acid secretion may be important in the genesis of ulcer disease or in gastroduodenal mucosal damage. In addition, new physiological information has established that the gas troduodenal mucosa is normally protected by a complex series of events includ ing mucus and bicarbonate secretion, cell renewal, surface mucosal restitution, and preservation of the microvasculature and mucosal proliferative zone.

Available in PDF, EPUB and Kindle. Book excerpt: The partition of fluid between the vascular and interstitial compartments is regulated by forces (hydrostatic and oncotic) operating across the microvascular walls and the surface areas of permeable structures comprising the endothelial barrier to fluid and solute exchange, as well as within the extracellular matrix and lymphatics. In addition to its role in the regulation of vascular volume, transcapillary fluid filtration also allows for continuous turnover of water bathing tissue cells, providing the medium for diffusional flux of oxygen and nutrients required for cellular metabolism and removal of metabolic byproducts. Transendothelial volume flow has also been shown to influence vascular smooth muscle tone in arterioles, hydraulic conductivity in capillaries, and neutrophil transmigration across postcapillary venules, while the flow of this filtrate through the interstitial spaces functions to modify the activities of parenchymal, resident tissue, and metastasizing tumor cells. Likewise, the flow of lymph, which is driven by capillary filtration, is important for the transport of immune and tumor cells, antigen delivery to lymph nodes, and for return of filtered fluid and extravasated proteins to the blood. Given this background, the aims of this treatise are to summarize our current understanding of the factors involved in the regulation of transcapillary fluid movement, how fluid movements across the endothelial barrier and through the interstitium and lymphatic vessels influence cell function and behavior, and the pathophysiology of edema formation.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive overview of invited contributions on Helicobacter pylori infection in gastritis and gastric carcinogenesis. The first part of the book covers topics related to the pathophysiology of gastric mucosal defense system and gastritis including the gastroprotective function of the mucus, the capsaicin-sensitive afferent nerves and the oxidative stress pathway involved in inflammation, apoptosis and autophagy in H. pylori related gastritis. The next chapters deal with molecular pathogenesis and treatment, which consider the role of neuroendocrine cells in gastric disease, DNA methylation in H. pylori infection, the role of antioxidants and phytotherapy in gastric disease. The final part presents the effects of cancer risk factors associated with H. pylori infection. These chapters discuss the serum pepsinogen test, K-ras mutations, cell kinetics, and H. pylori lipopolysaccharide, as well as the roles of several bacterial genes (cagA, cagT, vacA and dupA) as virulence factors in gastric cancer, and the gastrokine-1 protein in cancer progression.

Available in PDF, EPUB and Kindle. Book excerpt: The gastrointestinal mucosal defense system serves to minimize mucosal injury by either ingested or endogenously produced noxious substances. The mucosal defense system is stratified into pre-epithelial (alkaline mucus), epithelial (dynamic epithelial lining), and post-epithelial (microcirculation) components. The mucus lining the epithelial surface presents a diffusional barrier to ingested material (e.g., lipids) and also serves as an unstirred layer in which a pH gradient can be established to prevent acid-induced injury. The epithelial lining prevents entrance of any toxic material to the interstitium and, should it be damaged, it is rapidly resealed by migration of adjacent viable epithelial cells to cover the defect. Any acid or other material that has entered the interstitium is washed out by an intense neurogenic hyperemia. In general, the mucosal defense system is quite effective and any adverse gastrointestinal effects associated with the normal course of nutrient assimilation are minimal. However, there are two situations in which the mucosal defense system is known to be ineffective and result in gastric mucosal injury: inadvertent ingestion of H. pylori. or intentional ingestion of NSAIDs. H. pylori can penetrate the mucus layers and cause epithelial injury and inflammation, while at the same time preventing its clearance by the host immune system. NSAIDs weaken the mucus layer and cause epithelial cell injury.
