Abstract

Histamine-induced contractions of small airways from human lung were substantially augmented by the cyclo-oxygenase inhibitor, indomethacin, whereas the contraction of larger airways was not. Mixed cyclo-oxygenase/lipoxygenase inhibitors of arachidonic acid metabolism did not modify histamine-induced contractions of smooth muscle from either small or large airways but completely reversed the augmentation of histamine responses produced by indomethacin on the smaller airways. The SRS-A (slow reacting substance of anaphylaxis) antagonist, FPL55712, did not affect the augmentation of histamine-induced contractions by indomethacin.

摘要

组胺诱导的人肺小气道收缩,被环氧化酶抑制剂吲哚美辛显著增强,而大气道的收缩则未受影响。花生四烯酸代谢的环氧化酶/脂氧化酶混合抑制剂,对组胺诱导的小气道或大气道平滑肌收缩均无影响,但能完全逆转吲哚美辛对小气道组胺反应的增强作用。过敏反应慢反应物质(SRS-A)拮抗剂FPL55712,不影响吲哚美辛对组胺诱导收缩的增强作用。
