Rat mast cells, isolated from peritoneal fluids, were found to release substantial amounts of immunoreactive E-type prostaglandin when stimulated in vitro by foetal calf serum or incubated in the presence of arachidonic acid. Extracellular accumulation of iPGE reflected synthesis, rather than release of preformed material, since it was abolished by indomethacin, a potent and relatively specific inhibitor of prostaglandin synthetase. Hydrocortisone and Compound 48/80, in such experimental conditions, did not affect PGE release.
从腹腔液中分离出的大鼠肥大细胞,在体外受胎牛血清刺激或在花生四烯酸存在下孵育时,会释放大量免疫反应性E型前列腺素。细胞外iPGE的积累反映了其合成过程,而非预先形成物质的释放,因为它被吲哚美辛(一种强效且相对特异的前列腺素合成酶抑制剂)所抑制。在这种实验条件下,氢化可的松和化合物48/80不影响PGE的释放。
