Leech antiplatelet protein (LAPP) is a specific inhibitor of collagen-induced human platelet aggregation and adhesion to collagen under static conditions. Recombinant LAPP (rLAPP) and L-366,763 (acetylated-Cys-Asn-Pro-Arg-Gly-Asp-Cys-NH2), a peptidyl fibrinogen receptor antagonist, were evaluated in an anesthetized baboon thrombosis model using a collagen-coated graft segment of an arteriovenou...

Background: Coagulation activity of platelets plays an important role in thrombosis formation, Atherosclerotic plaque establishment and cardiovascular disorders. ASA are using as an anti platelet activity drug for patients with Coronary Artery Disease (CAD). Using of plant extraction as a complementary medicine for these patients (CAD) is mostly recommended by traditional medicine specialist. ...

Platelets play an indispensable role in human health and disease. Platelets are very sensitive to oxidative stress, as it leads to the damage of mitochondrial DNA, which is the initial step of a sequence of events culminating in the cell death through the intrinsic pathway of apoptosis. Owing to a lot of reports on secondary complications arising from oxidative stress caused by therapeutic drug...

To the Editor: Acetylsalicylic acid (ASA) has the property of inhibiting cyclo-oxy­ genase of both platelets and vessel wall intima.' However, a differential inhibition of the cyclo-oxygenase in the platelets has been claimed possible by low doses of ASA. Preservation of the vessel wall pro­ duction of prostacyclin, which is a potent inhibitor of platelet aggrega­ tion, would seem a therapeutic...

Recent advances in the development of i.v. platelet glycoprotein alphaIIb/beta3 integrin (GPIIb/IIIa) antagonists led to the development of either a class of small-molecular-weight antagonists with a short to ultra-short duration of antiplatelet effects (Integrelin, Tirofiban, DMP728) or a very long-acting antagonist (ReoPro). Thus the present study was undertaken to characterize the antiplatel...

objective: some of the adverse effects of aspirin including peptic ulcers, gastrointestinal bleeding and aspirin resistance compelled researchers to find a suitable alternative with fewer adverse effects. in this clinical trial, we aimed to find the effective antiplatelet dose of garlic. materials and methods: this randomized controlled clinical trial (rct) was conducted on 62 healthy volunteer...

a number of n-arylmethyl substituted indole derivatives have been synthesized and their effectiveness against adp and arachidonic acid induced platelet aggregation in human plasma was determined. the desired compounds were synthesized by reacting the appropriate aniline derivative with isatin (or substituted isatin) to form the corresponding imine structures. the so formed compound was then act...
