Heparin as a natural anticoagulant has frequently been suggested for use in blood transfusions, but the difficulty in obtaining a pure and potent product free from toxic effects, as well as the high cost of production, has been a hindrance to its trial and use. Mason1 in 1924 reported some...
DETERMINATION OF HEPARIN IN THE BLOODABSTRACTHeparin in the blood is determined over a wide range of concentrations by measuring the clotting time of serum derived from a test specimen of blood when combined under standard conditions with thrombin and plasma solutions. The clotting time is then dete...
Heparin, anticoagulant drug that is used to prevent blood clots from forming during and after surgery and to treat various heart, lung, and circulatory disorders in which there is an increased risk of blood clot formation. Discovered in 1922 by American
a severe lack of platelets in your blood; or uncontrolled bleeding.You may not be able to use heparin if you are unable to receive routine blood-clotting tests at the proper intervals during treatment.To make sure heparin is safe for you, tell your doctor if you have ever had:an...
It has been demonstrated that high blood vascular endothelial growth factor (VEGF) levels in patients with myocardial infarction decrease rapidly after reperfusion, possibly in response to heparin administration. We measured serum VEGF concentration before and after heparin infusion in 105 pat...
in defined orientations along the polysaccharide backbone. Heparin resembles DNA as both are highly charged linear polymers that behave as polyelectrolytes. Heparin is believed to function as an anticoagulant primarily through its interaction with AT III by enhancing AT-III-mediated inhibition of blood ...
The purpose of this research is to evaluate the necessity of using heparin in UltraTag RBC kits used for nuclear medicine studies. METHODS: Non-heparinized blood (n = 15) and heparinized blood (n = 15) were added into UltraTag RBC kits. The samples were evaluated for macroscopic blood clot...
The physiological function of heparin is not completely understood. It is found only in trace amounts in normal circulating blood. It exerts an antilipemic effect by releasing lipoprotein lipase from endothelial cells; heparinlike proteoglycans produced by endothelial cells have anticoagulant activity. ...
