Clotting of plasma and silicone surfaces.
T HE USE of silicone surfaces for blood clotting studies offers new technical approaches to the problems concerned. In their pioneer work, Jaques, Fidlar, Feldsted and Macdonald’ indicated the possibility that plasma may clot independently of platelet action. They suggest, as others have, that plasma may contain a soluble factor which will initiate clotting. In their studies, the platelet conce...
متن کاملPlatelet-Rich Plasma During Clotting
detected. Ii both cases malonic acid was by far the most abundant product. The traces of glutaric and adipic acid in the oxidation products of the C18 and C1,9 acid respectively, can be explained by the presence of C20 and C21 pentaenoic acid, from which the above dicarboxylic acids are the known oxidation products. However, the possible presence of small amounts of an isomeric octadecatetraeno...
متن کاملNeutrophil chemotaxis on silicone and polyurethane surfaces.
Silicone vascular catheters have a greater risk of infection and produce greater inflammation in vivo and greater complement activation in vitro than other vascular catheter polymer materials. This study investigated whether polymorphonuclear leukocyte (PMNL) chemotaxis under agarose on silicone surfaces is different than on polyurethane (PU). Glass slides were coated with silicone and PU by us...
متن کاملMechanism of plasma clotting by Erysipelothrix rhusiopathiae.
Experiments were performed to determine the mechanism by which Erysipelothrix rhusiopathiae clots plasma. Detection of plasma-clotting activity in four strains of E. rhusiopathiae was carried out by mixing a 24-h broth culture of a tested bacterial strain with rabbit plasma (tube coagulation test). Sodium citrate, sodium oxalate, EDTA, and heparin were used as anticoagulants in preparing the ra...
متن کاملPhotoelectric determination of plasma clotting times.
A photoelectric clot timer is described. The apparatus allows a large analytic capacity, with good precision and correlation to manual methods, and can be used with capillary blood. Prothrombin analysis according to the method of Quick and Owren, the Thrombotest method, and determinations of partial thromboplastin time are applicable to the apparatus. The semiautomated procedure is extremely si...
