Abstract
  1. Negatively charged phospholipids promote initiation of the contact activation system in the blood coagulation. 2. Neutral phospholipids were unable to activate this system. 3. The activation is inhibited by beta 2-glycoprotein I at physiological concentrations. 4. The results raise the question whether people with low concentration of beta 2-glycoprotein I are more easily exposed to blood coagulation defects, such as disseminated intravascular coagulation, than those with normal concentration of beta 2-glycoprotein I.
摘要
  1. 带负电荷的磷脂促进血液凝固中接触激活系统的启动。2. 中性磷脂无法激活该系统。3. 在生理浓度下,β2-糖蛋白I可抑制这种激活。4. 这些结果提出了一个问题,即与β2-糖蛋白I浓度正常的人相比,β2-糖蛋白I浓度低的人是否更容易出现凝血缺陷,如弥散性血管内凝血。
