Intradermal injection of 0.1 pmole (52 pg) of acetyl glyceryl ether phosphorylcholine (AGEPC) in guinea pigs induced increased vascular permeability assessed by a skin-blueing model. Rabbits and rats showed increased vascular permeability with 1.0 pmole (520 pg) of AGEPC. On a molar basis, from 1,000 to 10,000 times more histamine was required to induce skin blueing in the same animals. In rabbits and guinea pigs, the increased vascular permeability induced by AGEPC occurred as an early, transient phase and as a delayed, prolonged phase. The early, transient phase was not inhibited by chlorpheniramine doses which markedly reduced or abrogated histamine-induced blueing. AGEPC was 100 to 1000 times more potent than histamine on a molar basis for the induction of vasoconstriction in a blued skin assay in guinea pigs. These studies demonstrate that AGEPC has potent vasoactive properties and provide additional information that implicates this acetylated alkyl phosphoglyceride as a mediator of the acute inflammatory process.
