Human oxalated plasma stored at 4 degrees C. until the prothrombin time is increased beyond 60 sec. is a reliable medium for assaying labile factor (factor V) because its response to added labile factor corresponds quantitatively to that of plasma from patients with congenital deficiency of this factor. Such an agreement is not obtained with plasma stored at 37 degrees C. The stability of labil...
A Confounding Case of Inherited Factor V Deficiency Complicated by Inhibitors at First Presentation.

Because of the very short half-life of factor VII, prophylaxis in factor VII deficiency is considered a difficult endeavor. The clinical efficacy and safety of prophylactic regimens, and indications for their use, were evaluated in factor VII-deficient patients in the Seven Treatment Evaluation Registry. Prophylaxis data (38 courses) were analyzed from 34 patients with severe factor VII deficie...
A relatively potent antiserum against highly purified, unactivated human factor XI antigen was raised in a rabbit. This antiserum, after concentration, neutralized 50% of the factor XI clotting activity of a standard normal plasma at an antiserum dilution of 1/900. The antiserum was used in a neutralization-inhibition assay to study the relation between factor XI clotting activity and factor XI...
The factor V Leiden variant, responsible for the phenomenon of activated protein C resistance, was found to be less frequent among British (0.06) and Swedish/Danish (0.15) protein C deficiency patients than previously reported in a Dutch study (0.19).
