摘要:
目的观察艾叶提取物对FⅫ的作用位点并检测其所含物质,阐明其抗凝、促凝机制及药效物质基础。方法检测艾叶提取物干预下脑缺血病人血浆凝血4项、FⅫ活性;FⅫ、FⅫ-2含量;检测艾叶LODB1-6干预下血浆凝血3项、连续血浆凝固时间、FⅫ激活。液质联用分析LODB5。结果艾叶提取物延长了血浆APTT、PT、TT,降低高岭土对FⅫ的激活作用;各剂量组降低了FⅫ含量,但只有中、高剂量组FⅫ-2的含量降低。相比于LODB1-3,LODB5、6可延长APTT,LODB5还使TT延长;LODB5高剂量组和LODB6各剂量组FⅫ含量降低。液质联用分析LODB5,得到6种含量较高物质。结论艾叶提取物激活FⅫ产生促凝活性与EGF-Like2结构域有关。但艾叶提取...
摘要(英文):
Aim To observe the action site of FXII under extract of Artemisia argyi and to detect the substances in it, so as to clarify the anticoagulant mechanism of the extract of Artemisia argyi and the substance basis of its efficacy. Methods The four items of blood coagulation and FXII activity in plasma were detected under the intervention of Artemisia argyi extract. The activation of FXH and FXII-2 by Artemisia argyi extract was detected; the effects of LODBl-6 on three items of blood coagulation of plasma were detected, and the effects of differen...
