Inhibition of platelet aggregation by acadesine was evaluated both in vitro and ex vivo in human whole blood using impedance aggregometry, as well as in vivo in a canine model of platelet-dependent cyclic coronary flow reductions. In vitro, incubation of acadesine in whole blood inhibited ADP-induced platelet aggregation by 50% at 240 +/- 60 microM. Inhibition of platelet aggregation was time d...

We examined the role of microtubules in platelet aggregation and secretion (release reaction) induced by the calcium ionophore A23187 (0.8-5 muM). At these concentrations, platelet aggregation was preceded by a lag period of approximately 1 min. Colchicine (an agent that disrupts microtubule assembly-disassembly) was shown to bind to platelet microtubules by employing [(3)H]colchicine at a conc...

OBJECTIVES We sought to test the platelet inhibitory and anti-inflammatory effects of a higher statin dosage compared with combined treatment with ezetimibe plus a low statin dose. BACKGROUND Reducing the level of low-density lipoprotein cholesterol (LDL-C) with statins induces important pleiotropic effects such as platelet inhibition. An insufficient LDL-C reduction often is treated with eze...

INTRODUCTION Platelet aggregation plays a significant role in the etiology of cardiovascular diseases. Therefore, treatments to inhibit platelet aggregation can reduce the risk of coronary thrombosis. Several studies indicated that garlic can inhibit platelet aggregation. This study aimed to determine the effect of garlic in comparison with Plavix on platelet aggregation. MATERIALS AND METHOD...

The molecular basis for heparin-induced thrombocytopenia (HIT), a relatively common complication of heparin therapy, is not yet fully understood. We found that pretreatment of platelets with AR-C66096 (formerly FPL 66096), a specific platelet adenosine diphosphate (ADP) receptor antagonist, at a concentration of 100 to 200 nmol/L that blocked ADP-dependent platelet aggregation, resulted in comp...

background: bernard-soulier syndrome is a rare inherited bleeding disease caused by quantitative or qualitative defect of gpib/ix/v, a platelet complex that binds the von willebrand factor. the expression of gpib-ix-v complex can be evaluated by flow cytometry and confirmed by the absence of ristocetin-induced platelet aggregation in platelet-rich plasma. the main aim of the present study was t...
