目的:比较研究槲皮素与芦丁对离体大鼠胸主动脉环的作用及其可能的途径。方法:采用累积加药法,检测槲皮素和芦丁对去氧肾上腺素(pheny lephrine,PE)预收缩的胸主动脉环张力的影响。结果:槲皮素对离体大鼠内皮完整和去内皮的胸主动脉环...目的:比较研究槲皮素与芦丁对离体大鼠胸主动脉环的作用及其可能的途径。方法:采用累积加药法,检测槲皮素和芦丁对去氧肾上腺素(pheny lephrine,PE)预收缩的胸主动脉环张力的影响。结果:槲皮素对离体大鼠内皮完整和去内皮的胸主动脉环均有浓度依赖性的舒张作用,而芦丁对PE预收缩血管的舒张作用是内皮依赖性的。槲皮素和芦丁对内皮完整的胸主动脉环的最大舒张反应分别为(77.20±6.11)%和(44.28±7.48)%,但两者对内皮完整的胸主动脉环最大舒张的半数有效浓度无明显差异。用一氧化氮合酶抑制剂L-NAM E(0.1 mm o l/L)预处理后,可阻断芦丁诱导的舒张血管作用,但不能阻断槲皮素引起的舒张血管作用;用鸟苷酸环化酶抑制剂亚甲蓝(10μm o l/L)预处理后,两者的血管舒张作用均被阻断。用环氧合酶抑制剂吲哚美辛(10μm o l/L)预处理后可减弱槲皮素诱导的舒张血管作用,但不能阻断芦丁引起的舒张血管作用。结论:槲皮素的舒血管作用强于芦丁,槲皮素可能是通过鸟苷酸环化酶和环氧合酶途径产生非内皮依赖性的血管舒张作用,而芦丁可能是通过NO-鸟苷酸环化酶途径产生内皮依赖性的血管舒张作用。展开更多

For the last five years, our research group has cooperated with Institute of Medicinal Plants in Huairou District of Beijing, carrying out studies on Echinacea purpurea, which involved botany, cultivation, pharmacognosy, phytochemistry, quality control, pharmacology and toxicology of the species. Two other species introduced from Canada, Echinacea angustifolia and Echinacea pallida, were also included in the taxonomic, cultivated and pharmacognostic studies. The results acquired have opened up the path to introduce Echinacea species into Traditional Chinese Medicine, thus established the possibility of developing more promising drugs from them.展开更多
