摘要 [目的]研究虫草素抗炎作用及机制。[方法]通过二甲苯致小鼠耳肿胀实验研究虫草素不同剂量(50、100、200 mg/kg)对耳肿胀的抑制作用,在细胞水平研究虫草素(12.5、25、50μmol/L)对诱导型一氧化氮合酶(i NOS)和环氧酶-2(COX-2)表达和一氧化氮(NO)和前列腺素E_2(PGE_2)产生的影响。[结果]虫草素(200 mg/kg)能够抑制二甲苯致小鼠耳肿胀(P<0.05)和耳片中一氧化氮(NO)和前列腺素E_2(PGE_2)的产生(P<0.05)。在细胞水平虫草素(25、50μmol/L)能够抑制诱导型一氧化氮合酶(i NOS)和环氧酶-2(COX-2)表达(P<0.05),一氧化氮(NO)和前列腺素E2(PGE2)的产生(P<0.05)。[结论]虫草素具有抗炎作用。 [Objective] To study the anti-inflammatory effect of Cordycepin. [Methods] By Xylene induce ear swelling test in mice, the inhibition of Cordycepin(50, 100, 200 mg/kg)was evaluated for ear swelling. At the cellular level, the effect of Cordycepin(12.5, 25,50 μmol/L)was evaluated for i NOS and COX-2 expression, NO and PGE2 production. [Results] Cordycepin(200 mg/kg)inhibited ear swelling of mice(P〈0.05), NO and PGE2 production in mouse ear piece(P〈0.05). At the cellular model, Cordycepin(25, 50 μmol/L)inhibited i NOS and COX-2 expression(P〈0.05),NO and PGE2production(P〈0.05). [Conclusion] Cordycepin have anti-inflammatory effect.
