The procoagulant protein F.VIII:C is noncovalently bound to von Willebrand factor (vWF) to give the factor VIII macromolecular complex. New highly purified preparations of isolated human F.VIII:C, devoid of vWF and about 500,000-fold purified, were administered to hemophilia A and von Willebrand disease (vWD) dogs to determine their hemostatic effectiveness(More)
The kinetics and tissue distribution of 3H-heparin and a 3H-labelled low molecular weight heparin fragment were compared in normal rabbits as well as in rabbits with blocked renal function or reticuloendothelial system (RES). Radioactivity in plasma, urine, liver and kidneys, as well as anti-FXa activity in plasma were determined. The plasma elimination of(More)
A tritium-labelled low molecular weight heparin fragment with an average molecular weight of 4000-6000 (Fragmin), was fractionated into its high and low affinity forms for antithrombin. The fractions obtained were injected into rabbits, and the plasma half-life (t1/2) volume of distribution (Vd), area under the curve (AUC), total body clearance (TCl) and(More)
A procedure for rat bone marrow differential analysis using flow cytometry and commercially available monoclonal antibodies is described. The method uses a combination of the differential expression of leucocyte common antigen (CD45) on different cell lineages and the expression of transferrin receptor (CD71). This is coupled with the side scatter(More)
A template bleeding time study in the rat was undertaken to see if it is possible to correlate bleeding times with the molecular weight, anticoagulant activity or chemical composition of heparin or heparin-derived compounds. Heparin from porcine intestinal mucosa (PM-heparin) and from bovine lung (BL-heparin) as well as heparin fragments from these sources(More)
Size homogeneous heparin oligosaccharides were prepared from nitrous acid depolymerized heparin by means of repeated gel filtration chromatography. These oligosaccharides were then further separated with respect to affinity for antithrombin by means of affinity chromatography. All the high-affinity oligosaccharides thus obtained had a strong ability to(More)
The coagulation variables thrombin time (TT), activated partial thrombin time (APTT) and prothrombin time (PT), were investigated in mouse plasma. TT and APTT clotting times were determined using a KC10 coagulation analyser and test kits Dia Thrombin (bovine thrombin diluted to a concentration of 2.5 U/l) and Dia Celin-L (rabbit brain cephaloplastin,(More)
