Prostaglandin D2 is the prevailing prostaglandin in the acute inflammatory exudate of urate arthritis in the chicken.
An acute inflammation was elicited in intertarsal joints of chicken by injection of urate crystals. Inflammatory exudates recovered at different times were assayed for prostaglandin D2(PGD2)E2 and F2 alpha and thromboxane B2 content by specific radioimmunoassays. We found that PGD2 was the prevailing prostaglandin reaching concentrations up to 10 times in excess of PGE2. This finding was confirmed by gas chromatography-mass spectrometry. It is concluded that PGD2 should be considered as a possible mediator of acute inflammation.
