中文摘要: |
阿魏酸钠(SF)在体外可抑制家兔血小板血栓素 A2的合成,剂量与效应相关,IC50为0.762mmol/L。SF 在明显抑制血栓素 A2生成的同时,血小板前列腺素 E2和前列腺素 F2a 的生成也显著减少此作用类似阿司匹林,说明 SF 为血小板环氧酶抑制剂。SF 在浓度高于0.8mmol/L时,(14)C-花生四烯酸的利用率明显降低,提示 SF 可能对血小板脂氧酶活性也有抑制作用。 |
英文摘要: |
Sodium ferulate(SF)is one of the antiplatelet ingredients in Angelica sinensis,The effect of SF on14C-arachidonic acid metabolism in washed intact rabbit platelets was studied with radio- chromatography and radioautography.SF(0.1~3.2mmol/L)inhibited the generation of platelet throm- boxane B2 in a dose-dependent manner(reduced by 16.7~93.8%),and the IC50was shown to be 0.762mmol/L.The formation of PGE2 and PGF2awas also reduced significantly when SF was used at high concentration(0.8~3.2mmol/L).These results indicated that SF might be a platelet cyclo- oxygenase inhibitor.Since the utilization of(14)C-AA was obviously suppressed(P<0.001)at the concentrations higher than 0.8mmol/L,the activity of platelet 12-lipo-oxygenase might also be inhibited by SF. |
