Synthesis and metabolism of prostaglandins E2, F2alpha and D2 by the rat gastrointestinal tract. Stimulation by a hypertonic environment in vitro.

H R Knapp, O Oelz, B J Sweetman, J A Oates.   

Abstract

Whole cell preparations of rat stomach corpus, jejunum, and colon were incubated and the released prostaglandin E2 (PGE2), PGF2alpha, PGD2, 15 keto-13,14 dihydro PGE2, and 15 keto-13, 14 dihydro PGF2alpha were measured by combined gas chromatography-mass spectrometry. All regions made PGD2 and possessed a high capacity for production 15 keto-13,14 dihydro derivatives of both PGE2 and PGF2alpha. Hypertonic sucrose solutions resulted in concentration-dependent increases in prostaglandin release, particularly of PGE2 and its metabolite. It is suggested that PG's may play a role in the local effects of luminal hyperosomolarity on digestive tract functions.
