Indomethacin enhanced macrophage cytostasis against MOPC-315 tumor cells in vitro. The effect of indomethacin was inhibited by prostaglandin E2 and by the lipoxygenase inhibitor nordihydroguaiaretic acid. Prostaglandin E2 and nordihydroguaiaretic acid also inhibited indomethacin stimulation of macrophage thymidine incorporation. Indomethacin inhibited macrophage prostaglandin E2 formation and stimulated leukotriene B4 synthesis. Nordihydroguaiaretic acid inhibited leukotriene B4 production. Our data indicate that eicosanoids play a role in regulating macrophage cytostasis.
吲哚美辛在体外增强了巨噬细胞对MOPC - 315肿瘤细胞的细胞生长抑制作用。前列腺素E2和脂氧合酶抑制剂去甲二氢愈创木酸可抑制吲哚美辛的作用。前列腺素E2和去甲二氢愈创木酸也抑制吲哚美辛刺激的巨噬细胞胸腺嘧啶核苷掺入。吲哚美辛抑制巨噬细胞前列腺素E2的形成并刺激白三烯B4的合成。去甲二氢愈创木酸抑制白三烯B4的产生。我们的数据表明,类花生酸在调节巨噬细胞细胞生长抑制中起作用。
