Abstract
The immunological release of SRS-A was investigated in guinea-pig chopped lung. A number of unsaturated fatty acids, all of which are substrates for arachidonate lipoxygenase were found to potentiate the release of SRS-A. This potentiation was enhanced by indomethacin, a cyclo-oxygenase inhibitor, and completely reversed by nordihydroguaiaretic acid (NDGA) and eicosatetraynoic acid (ETA) which inhibit lipoxygenase. This suggests that some aspect of arachidonate lipoxygenase action stimulates release of SRS-A and that release of SRS-A is increased by redirection of arachidonic acid (AA) metabolism via the lipoxygenase pathway (Hamberg, 1976). However, although exogenous 14C-AA increased SRS-A output it was not incorporated into SRS-A.
