Abstract

An inhibitory activity for the contact phase of the intrinsic coagulation pathway was demonstrated in an extract of adult Schistosoma mansoni. Inhibition is apparently specific for the enzymatic activation of Factor XI (pre-PTA) by Factor XIIa (activated Hageman factor). This phenomenon offers an explanation for the schistosomal evasive mechanism of the host contact hemostatic defense system.

摘要

在曼氏血吸虫成虫提取物中证实了对内源性凝血途径接触相的抑制活性。这种抑制显然对因子Ⅻa(活化的哈格曼因子)激活因子Ⅺ(前凝血活酶原)的酶促反应具有特异性。这一现象为血吸虫逃避宿主接触性止血防御系统的机制提供了解释。
