Development Of The Gastrointestinal Mucosal Barrier
Nutrition Reviews, 2009In young rabbits, advancing age and natural feeding promote the development of an efficient mucosal barrier capable of protecting the host's circulation from penetration by potentially antigenic macromolecules.

HIV infection and the intestinal mucosal barrier
Annals of the New York Academy of Sciences, 2012HIV infection induces a barrier defect of the intestinal mucosa, which is closely linked to immune activation and CD4 T cell depletion. The HIV‐induced barrier defect is initiated in early acute and maintained through chronic infection. In acute infection, increased epithelial permeability is associated with increased epithelial apoptosis possibly ...

Characterization of the Barrier Properties of Mucosal Membranes
Journal of Pharmaceutical Sciences, 1990The barrier properties of the nasal, rectal, and vaginal membranes were investigated in the rabbit by comparing physical characteristics and permeability to model hydrophilic and lipophilic compounds. It was found that the nasal, rectal, and vaginal mucosae differ in their physical characteristics and interactions.

Intestinal Inflammation and Mucosal Barrier Function
Inflammatory Bowel Diseases, 2014Intestinal mucosal barrier function is the capacity of the intestine to provide adequate containment of luminal microorganisms and molecules while preserving the ability to absorb nutrients. The central element is the epithelial layer, which physically separates the lumen and the internal milieu and is in charge of vectorial transport of ions ...

Salicylate Damage to the Gastric Mucosal Barrier
New England Journal of Medicine, 1967EVER since Reaumur, more than two centuries ago, discovered that gastric juice digests meat, men have asked: "Why doesn't the stomach digest itself?" There are two answers to this question. One is, of course, that sometimes the stomach does digest itself, with disastrous consequences.

The mucosal immune system at the gastrointestinal barrier
Best Practice & Research Clinical Gastroenterology, 2008The immune system faces a considerable challenge in its efforts to maintain tissue homeostasis in the intestinal mucosa. It is constantly confronted with a large array of antigens, and has to prevent the dissemination and proliferation of potentially harmful agents while sparing the vital structures of the intestine from immune-mediated destruction ...

The effect of metiamide on the gastric mucosal barrier
Journal of Surgical Research, 1977Abstract The effect of Metiamide, an H2-receptor antagonist, on the hydrogen ion back diffusion and transmucosal electrical potential difference was tested in the nonsecreting in vitro frog gastric mucosa. Under the conditions of this study, the topical application of Metiamide did not effect either hydrogen ion back diffusion or transmucosal ...

A physical identity for the gastric mucosal barrier
Medical Journal of Australia, 1990An oligolamellar lining which is probably phospholipid has been demonstrated on the gastric mucosal surface of the rat by transmission electron microscopy using fixation procedures specially developed to avoid the destruction of hydrophobic surfaces. This structure is unlikely to be an artefact since the use of two hydrophobic probes in epifluorescence

Most gastroduodenal ulcer disease results from a weakness in the normal gastric mucous barrier against the penetration of acid secreted by the stomach. Based on meticulous and insightful research, the distinguished physiologist Franklin Hollander hypothesized that the stomach is protected against its own acid secretion by a dynamic two-component mucus ...
