Abstract

Release of cyclooxygenase products from primary cultures of dog or human tracheal epithelium was measured by radioimmunoassay. In both species, bradykinin, platelet-activating factor (PAF), and A23187 (a calcium ionophore) caused increases in the rate of release of prostaglandin (PG) E₂ and smaller increases in PGF(2α), 6-keto-PGF(1α), and thromboxane B₂ output. Isoproterenol, vasoactive intestinal peptide (VIP), metacholine, and leukotrienes C₄ and D₄ had no effect on release of these cyclooxygenase products. Gas chromatography-mass spectrometry showed that the ratio of PGE₂ to PGD₂ released from dog cells by A23187 was 30:1. Short-circuit current across dog cells was stimulated by bradykinin, A23187, PAF, VIP, methacholine, and isoproterenol. Only the responses to bradykinin and A23187 were reduced by pretreatment with indomethacin.
