Haemorrhagic diathesis of the newborn is usually characterized by a physiological deficiency of prothrombin and probably also by a deficiency of proconvertin (van Creveld, Paulssen, Ens, Mey, Versteegh and Versteeg, 1954). Sometimes a third clotting-factor, pro-accelerin, is also lacking. We found a simultaneous deficiency both of prothrombin and pro-accelerin in some cases of intra-uterine mel...

Aeromonas sobria infection often advances to sepsis, in which interaction of bacterial components with plasma proteins possibly causes various disorders. This bacterium releases a serine protease (ASP), a putative virulence factor, and binds to fibrinogen. To study the ASP effect on fibrinogen, we incubated fibrinogen or plasma with ASP and investigated their clotting elicited by thrombin, whic...

Two structurally different forms of activated human Factor IX (Factor IXaa and IXa8) have been previously reported to have essentially identical clotting activity in vitro. Although it has been shown that activated Factor IXChapel Hills an abnormal Factor IX isolated from the plasma of a patient with mild hemophilia B, and normal Factor IXaa are structurally very similar, the clotting activity ...

445 shunts, there was no mention of the type of graft material or the technique of pre-clotting used for the ascending aortic graft itself. Certainly, massive bleeding has been described frequently in the early post-bypass period following ascending aortic aneurysm resection in many series and it has been seen at times by virtually all of us who have occasion to perform these procedures. Undouh...

BACKGROUND Hypothermia and hemorrhagic shock contribute to coagulopathy after trauma. In this study, we investigated the independent and combined effects of hypothermia and hemorrhage with resuscitation on coagulation in swine and evaluated clinically relevant tests of coagulation. METHODS Pigs (n = 24) were randomized into four groups of six animals each: sham control, hypothermia, hemorrhag...
