Abstract:
We examined the role of platelet activating factor in dextran induced colitis in mice. The release of pro-inflammatory platelet activating factor by colonic mucosa after the application of prednisolone was markedly decreased, unaffected after treatment with the platelet activating factor receptor antagonist BN52021 and significantly increased after treatment with 5-amino-salicylic acid and diclofenac. This increase of platelet activating factor could be responsible for the harmful effects often seen after treatment with specific cyclooxygenase inhibitors during inflammation.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
