Abstract

Proton pump inhibitors (PPIs) are antiulcer agents that have gastric antisecretory and mucosal protective actions. The antisecretory effect of these agents derives from the inhibition of gastric parietal cell proton pump H+/K+ ATPase. The exact mechanism of PPI-induced gastric mucosal protection is not known though. It has been suggested that PPI may accumulate, modulating the functions of neutrophils and, thus, may be useful in reducing the gastric mucosal injury caused by these cells. However, these same mechanisms may not be desirable when PPIs are prescribed in prophylaxis and pre-operatively for ill or immunodepressed patients. The present study was designed to examine a possible anti-neutrophil activity of pantoprazole in vivo. A short study with omeprazole and lanzoprazole was also performed. Dosages of PPIs able to inhibit basal acid secretion (10 and 100 mg kg(-1)) were administered intraperitoneally (i.p.) to rats for 7 or 28 days. Cimetidine (100 mg kg(-1)) and dexamethasone (0.75 mg kg(-1)) were used as controls for antisecretory and anti-inflammatory activity, respectively. Air pouches were then developed in these animals, and Helicobacter pylori suspension or carrageenan was used as inflammatory stimulus. Exudate ...Continue Reading

Atrophic Gastritis

Atrophic Gastritis is a process where gastric glandular cells are lost and replaced with firbous tissues, as a result of chronic inflammation. Learn more about Atrophic Gastritis here.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Anthelmintics

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
