title: The metabolism of prostaglandins F2alpha and E2 by non-pregnant porcine endometrial and luteal tissue and early pregnant porcine endometrial tissue, luteal tissue and conceptuses in vitro.
abstract: Slices of porcine endometrium and corpus luteum from both early pregnant and non-pregnant sows and conceptuses from early pregnant sows were incubated with radioactive PGF2alpha and PGE2 and the degree of metabolism of the prostaglandins measured. Prostaglandins and a metabolites were separated by TLC, radioactive bands located with a Panax scanner and the radioactivity measured in a scintillation counter. Endometrial and luteal tissue from non-pregnant sows gave no significant metabolism at any stage of the oestrous cycle, and while similar tissue from pregnant sows metabolised both prostaglandins slightly, only the conceptuses gave any significant metabolism. The possible physiological significance of these results is discussed.
