Abstract:
In 5 random groups of Wistar rats (n = 15 for each group), ulcerogenic doses of NSAIDs COX-1-COX-2 inhibitors such as indomethacin were compared with Celecoxib (COX-2 inhibitor); the production of antrum gastric ulcers and bowel and colon necrotic areas was studied. Celecoxib was given each 12 hs orally and subcutaneously during 5 days and gastrointestinal lesions were not found; in contrast, Celecoxib given after indomethacin aggravated antrum gastric ulcers (p < 0.001); intestinal massive necrosis and death were observed in all the rats. We conclude that Celecoxib does not induce gastrointestinal lesions in healthy mucosa; in contrast, Celecoxib amplifies the gastrointestinal lesions induced by indomethacin.

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...
