Abstract:
Cats were subjected to a standardized 3-h septicemia by intravenous infusion of live Escherichia coli in an LD50 dose. The effect of pentagastrin stimulation on the development of gastric mucosal injury was studied. There was no hemodynamic difference between the series during septicemia. Thus, pentagastrin did not induce increased gastric blood flow during the period of E. coli infusion. Intraluminal gastric pH was lower in the series given pentagastrin during the last 2 h of septicemia. Nevertheless, the extent of gastric mucosal injury was similar in the two groups, whereas the depth of injury was, if anything, less pronounced in the pentagastrin-stimulated group.

Pathophysiology of Peptic Ulcer Disease: Injurious Factors
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...

Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
