Platelet Function and Factor 8 in Uremia

Platelet Function and Factor VIII in Uremia*

Defective ADP-induced platelet factor 3 activation in uremia.

P ATIENTS \VITH UREMIA frequently have both prolonged bleeding times,11#{176} suggesting poor platelet plug formation, and impaired prothrombin consumption,1’2’46’#{176}14 ascribed to defective platelet factor 3 activalion. Considerable evidence points to the presence of a qualitative platelet defect in uremia, since such abnormalities cannot be attributed to the mild thrombocytopenia occasiona...

Platelets and Platelet Phosphatides in Uremia

By Gsaw n ALTSCHULER, AARON J. MARcus AND H uims L. Uu i N I HE HEMORRHAGIC tendency which develops in uremia is a well recognized clinical entity but the pathogenesis of this complication is not understood.’ In the past defective blood coagulation2 as well as increased vascular fragility3 have been suggested. The possibility of a functional blood platelet abnormality was first noted by Lewis, ...

Flow Cytometric Measurement of CD41/CD61, CD42b Platelet Receptors and Platelet Factor 3 Activity in Lyophilized Infusible Platelet Membrane Preparation

Background: The short life time of human platelet units has led to a chronic shortage of fresh platelets in blood transfusion centers. Many approaches have been investigated experimentally to produce new hemostatically active platelet products that are capable of long term storage. Infusible platelet membrane (IPM) prepared from fresh or outdated human platelets have been developed as an altern...
