title: Inflammatory effects of prostacyclin (PGI2) and 6-oxo-PGF1alpha in the rat paw.
abstract: In the rat paw prostacyclin was 5--10 times less potent than PGE2 in causing oedema, and 5 times less potent in potentiating carrageenin-induced oedema, which it did in a dose-related manner. Prostacyclin was 5 times more potent than PGE2 in producing hyperalgesia and as potent as PGE2 in restoring carrageenin-induced hyperalgesia. The effects on oedema were longer lasting than those on hyperalgesia. 6-oxo-PGF1alpha was 500 times less potent than PGE2 in causing oedema by itself and in potentiating carrageenin-induced oedema. It had no hyperalgesic activity in this test.
