Abstract
A unique property of gastric mucosa is its ability to withstand the insults imposed by the luminal contents and to resist the challenge by invading bacteria. Although there is no general agreement as to the mechanism of mucosal protection, the consensus is that this phenomenon is multicomponential in nature, and includes at least three major defense perimeters, which are the mucus-bicarbonate zone, the cell membranes of gastric epithelium, and the mucosal blood flow [1–4]. Hence, the brunt of luminal insults, at least in the initial stage, falls on the mucus layer, which constitutes the only identifiable physical barrier between the gastric lumen and the surface epithelial cells of the mucosa. The integrity of this defense perimeter depends upon a delicate dynamic equilibrium, controlled by factors affecting the synthesis, secretion, and breakdown of its constituents [3, 5, 6]. While this equilibrium is maintained successfully under normal physiological conditions, injury to the mucosa ensues when aggressive forces overcome factors that control mucosal defense.
