Platelet activating factor: release from colonic mucosa in patients with ulcerative colitis and its effect on colonic secretion.
Any attempt to block its release in patients with ulcerative colitis may have only a partial effect on their symptoms, as PAF accounted for 46% of the culture medium secretory effect.
Use of coculture of colonic mucosal biopsies to investigate the release of eicosanoids by inflamed and uninflamed mucosa from patients with inflammatory bowel disease.
In some patients with proctosigmoiditis and in all patients with Crohn's disease quiescent mucosa appears to be sensitised and it is likely that these and other cells are primed to release eicosanoids and may be induced to do so by soluble mediators produced by actively inflamed tissue.
Potential role for interleukin-1 in the pathophysiology of ulcerative colitis.
1. Biopsies of colonic mucosa from patients with ulcerative colitis liberated more interleukin-1 beta, prostaglandin E2, leukotriene C4 and platelet-activating factor into the medium in which they…
Influence of atrial natriuretic peptide on mammalian large intestine.
Inter-relationships between inflammatory mediators released from colonic mucosa in ulcerative colitis and their effects on colonic secretion.
Analysis of observations suggests that a combination of arachidonic acid derivatives accounts for about half the secretory response, and other products of phospholipase A2 activity are probably responsible for much of the remainder, leaving up to 20% the result of types of mediator not determined in this study.
Plasmodium falciparum and hepatitis B virus co-infection – a rare cause of acute hepatitis To the
The crux of the issue is that the different types of epithelium that constitute IPMNs frequently coexist, although one type tends to predominate and the IPMN should be labeled after the predominant epithelial type.

A very unusual case in which the skin around Ileostomy stoma showed features of active ulcerative colitis many years after having proctocolectomy is presented.
