摘要：

Production of several metabolites of arachidonic acid by purified rat serosal mast cells in response to stimulation with the ionophore A23187 was assessed by stable isotope dilution assay using gas chromatography-mass spectrometry. Compounds quantified were prostaglandins D2, E2, F2α, 6-keto-Fα, thromboxane B2, and 12-hydroxy-5,8,10,14-eicosatetraenoic acid. Mast cells incubated at 37°C for 30 min without ionophore produced measurable quantities of all metabolites assayed. 4 μm A23187 resulted in substantial increased synthesis of all metabolites compared to control cells. Of the metabolites quantified, prostaglandin D2 and prostacyclin were the major products derived from arachidonic acid in ionophore-stimulated rat mast cells. © 1979.
