摘要: 本文以大鼠胸腔白细胞为材料,采用高效液相色谱法(HPLC)、放免分析法(RIA)和荧光分光光度法分别测定大鼠腹腔白细胞内白三烯B4(LTB4)、5-羟二十碳四烯酸(5-HETE)、环一磷酸腺苷(cAMP)及游离钙水平。结果表明,在2.0~10.0 μg/mL浓度范围内,小白蒿总黄酮可剂量依赖性地抑制完整中性白细胞中LTB4的生物合成。另外,小白蒿总黄酮对人工三肽(fMLP)激发的白细胞内游离钙升高具有抑制作用,并促进细胞内cAMP水平提高。小白蒿总黄酮显著影响白细胞的多种功能,这可能与其抗炎作用机理有关。

Abstract: In this study,rat neutrophils from pleural fluid was used as experimental material to determine the levels of LTB4,5-HETE,Ca2+ and cAMP with HPLC,RIA and Fura-2/ AM,respectively.As a results, Artemisia frigida total flavonoids inhibited the formation of LTB4 from the intact neutrophils with its concentration increasing from 2.0 to 10.0 mg/L,and inhibited the Ca2+ stimulated by fMLP and promoted the improvement of cAMP in the cells.The effects of A.frigida total flavonoids on leukocyte function may be the mechanisms of its antiinflammatory action.

Key words: Artemisia frigida, total flavonoid, LTB4, Ca2+, cAMP
