Cultured rabbit gastric epithelial cells producing prostaglandin I2
Abstract:
A new method with Dispase, a bacterial neutral protease, was developed for purification of gastric mucosal cells from rabbit fetuses. These cells formed a typical polygonal monolayer after removal of fibroblastlike cells by Dispase treatment, and preserved the features of "normal" cells, exhibiting in vitro aging with a finite life span. The culture consisted mainly of surface mucous cells (50%-60% of the total cell population) and produced prostaglandins (predominantly I2). The addition of acetylsalicylic acid to the culture medium caused marked inhibition of prostaglandin production by the cultured gastric epithelial cells. This epithelial cell strain will be useful in studies on cytoprotection of the stomach.

Hormones Secreted by the Stomach
Each of these hormones secreted by different enteroendocrine cells plays a unique role in digestion. Here are a few examples:
Mucosal Barrier of the Stomach
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...
