Thrombocytopenia was associated with the presence of heparin-coated pulmonary artery catheters in 12 patients with heparin-associated antiplatelet antibodies. The thrombocytopenia persisted so long as the heparin-coated catheters were in place, even when all other sources of heparin were discontinued. The high morbidity and mortality associated with heparin-induced thrombocytopenia mandates tha...

We determined the suitability of various heparin salts used for anticoagulation of whole-blood specimens for measurement of ionized calcium (iCa), blood gases, and electrolytes. We were particularly interested in a new heparin product containing both zinc and lithium cations (CNLZ heparin), in which the binding sites with greatest affinity for divalent cations are bound with zinc and low-affini...

The effects of heparin-superoxide dismutase (SOD) conjugate (heparin-SOD) on γ-radiation induced DNA damage in vivo and in vitro were evaluated. Plasmid pcDNA3.0 solution was mixed with heparin-SOD, SOD, and a mixture of heparin and SOD (heparin + SOD), respectively, and irradiated with (60)Co at a dosage of 120 Gy. DNA injury was analyzed using agarose gel electrophoresis. The results showed t...

Enhancing oral bioavailability of hydrophilic drugs by encapsulation in lipid-based nanocarriers, including Solid Lipid Nanoparticles (SLN), has been well documented. In this work, high molecular weight heparin was “insolubilized” an “ion-paring” approach, forming Chitosan/Heparin Polyelectrolyte Complexes (PEC) to promote its SLN. Hybrid PEC-SLN, heparin-loaded SLN (H-SLN) as naked PEC were pr...

BACKGROUND Heparin-induced thrombocytopenia is a relatively uncommon but severe side-effect of heparin therapy. Heparin-induced IgG antibody has been elucidated to be the main isotype and the most pathogenic antibody in the pathophysiology. As affected patients are at high risk of developing thrombotic events, confirmation of the clinical diagnosis and avoidance of heparin re-exposure are impor...

BACKGROUND Myeloproliferative neoplasms (MPN) encounter thromboses due to multiple known risk factors. Heparin-induced thrombocytopenia (HIT) is a thrombotic syndrome mediated by anti-platelet factor 4 (PF4)/heparin antibodies with undetermined significance for thrombosis in MPN. We hypothesized that anti-PF4/heparin Ab might occur in MPN and promote thrombosis. METHODS Anti-PF4/heparin antib...

Heparin and its low molecular weight are anticoagulants that prevent the formation extension of blood clots. However, these anticoagulant causes bleeding takes longer to stop. Here, we explore using magnetic iron oxide (Fe3O4NPs) coated with green tea (GTPs) as a safe effective nontherapeutic agent for clotting prevention. In this work, Magnetic (GT@Fe3O4NPs) was successfully synthesized simple...

Plasma levels of antithrombin-heparin cofactor, determined by heparin-dependent antithrombin assay, and antithrombin III antigen were measured in 22 members of a large kindred predisposed to venous thrombosis. While 11 members had reduced plasma levels of both antithrombin-heparin cofactor and antithrombin III antigen, the levels of antithrombin-heparin cofactor were always greater than the lev...
