摘要: Abstract To further define the role of mast cells in idiopathic inflammatory bowel diseases, mediator release from intestinal derived actively inflamed and relatively quiescent areas ulcerative colitis was studied. It hypothesized that diseased segments would indicate involvement disease process by releasing a different profile mediators than uninflamed tissue. Mast cell-containing suspensions matched 12 specimens were compared for responsiveness to cell stimulus goat anti-human immunoglobulin E. Supernatants challenged analyzed levels three mediators, histamine, prostaglandin D 2 , sulfidopeptide leukotriene C. involved released significantly greater amounts leukotriene. The difference histamine not result stores active tissue cells, because total content greater. enhanced both preformed newly generated indicates activation those course points contribution these disorders.
