Abstract
Subject headings
Close
- We have demonstrated in sensitized rats that the immediate response to endointestinal challenge with allergen (10(-6) M ovalbumin) is characterized by mucosal exudation of plasma with little or no concomitant change in the mucosal absorption capacity. The luminal entry of plasma macromolecules also leaves the light microscopic structure and the ultrastructure of the mucosa unaffected. It is possible that the plasticity of epithelial zonulae occludens allows a noninjurious and unidirectional paracellular flux of extravasated plasma into the gut lumen. We propose that inflammatory-stimulus-induced mucosal exudation of plasma belongs to the first-line defense mechanisms of the intact lining of the intestine.
