چکیده

were measured in eight healthy males by simultaneous ileal and colonic perfusion. Ileal flow was increased by PGF2e (six subjects)from a mean of 169 ml min-1 to 4 63 ml min-1 (p < 0.01); it also increased in the two subjects given PGE2. Colonic absorptive function was not significantly diminished by either prostaglandin. These results suggest that diarrhoea due to prostaglandins originates in the small intestine.

15-Hydroxyprostaglandin dehydrogenase as a marker in colon carcinogenesis: analysis of the prostaglandin pathway in human colonic tissue

BACKGROUND/AIMS Cyclooxygenase-2 (COX-2), 15-hydroxyprostaglandin dehydrogenase (15-PGDH), and microsomal prostaglandin E synthase-1 (mPGEs-1) regulate prostaglandin E2 (PGE2) expression and are involved in colon carcinogenesis. We investigated the expression of PGE2 and its regulating genes in sporadic human colon tumors and matched normal tissues. METHODS Twenty colonic adenomas and 27 colo...

Prostaglandin E2 produced by Entamoeba histolytica binds to EP4 receptors and stimulates interleukin-8 production in human colonic cells.

Entamoeba histolytica pathogenesis in the colon occurs in a stepwise fashion. It begins with colonization of the mucin layer, which is followed by stimulation of a proinflammatory response that causes nonspecific tissue damage that may facilitate parasite invasion of the underlying colonic mucosa. Unfortunately, the parasite and/or host factors that stimulate a proinflammatory response in the g...
