APPEARANCE OF PLATELET - CLUMPING SUBSTANCE 349 Appearance of Platelet - Clumping Substance After Acidification of Heparinized Plasma of Rabbit
I T IS WELL DOCUMENTED that platelet-thrombi are found during some inflammatory processes, but the exact mechanisms involved are still unknown. The authors demonstrated’3 the appearance of platelet-clumping substance in heparinized rabbit plasma and a concomitant decrease in the circulating platelet count after the intravenous injection of high molecular weight substances such as bacterial endo...
متن کاملAppearance of platelet-clumping substance in plasma of rabbits after intravenous injection of agar-solution, bacterial endotoxin or adrenaline.
I N 1958, Shimamoto et al.’ reported platelet aggregation induced by hepari iized plasma of rabbits treated with bacterial endotoxin, and concluded that this was due to an appearance of platelet-clumping substance in plasma. These results were confirmed in vitro by Des Prez, Horowitz and Hooks in 1961. Since then, many investigators have reported adenosine diphosphate (ADP), thrombin, adrenalin...
متن کاملAcid mucopolysaccharides as cofactor in formation of platelet-clumping substance.
Incubation at 37#{176}Cfor 30 mm or the addition of CaCl2 (5 mM) generated platelet-clumping activity in citrated plasma and EDTA plasma previously acidified to pH 5.5 and in which heparin was added to give a concentration of 0.5 mg/mi. Similar treatment could not produce platelet-clumping activity in saline or denatured plasma that had been heated to 56#{176}C.Heparin, chondroitin sulfate B, o...
متن کاملChromatographic and electrophoretic separation of platelet-clumping substance in rabbit plasma.
The authors previously reported that platelet-clumping substance (SHIMAMOTO and YAMAZAKI, 1958)1) was detected in heparinized plasma from rabbits administered adrenaline or high molecular weight substance such as agar solution and bacterial endotoxin by an intravenous injection.2) The plateletclumping substance also came to be observed in vitro of ter weak acidification of plasma in the presenc...
