title: [Revision of the biological significance of the contact system].
abstract: Current concept of blood coagulation is divided into two stages: an "initiation" stage which is handled by tissue factor pathway, and an "augmentation" stage handled by intrinsic pathway beginning in factor XI. Recent studies have demonstrated that the contact system is a modulator for vascular biology with vascular tone regulation, anticoagulant, profibrinolytic, antiadhesive and proinflammatory functions. Changes of contact system are associated with sepsis, thrombosis, etc.
