Abstract Background and Objectives Platelet gel prepared from platelet-rich plasma, containing growth factors, accelerates reconstruction of skin layers, stimulation of angiogenesis and increase of collagen synthesis in wounds healing process. In this study, the effect of human platelet gel on was investigated VEGF expression in experimental skin wounds in rat. Materials and Methods In thi...
Background: Platelet activation and aggregation plays an essential role in the for-mation of coronary artery thrombosis. Nowadays, the Clopidogrel is administered oral-ly as an inhibitor of platelet aggregation. Due to the high price of the original brand of Clopidogrel (Plavix), an Iranian brand of Clopidogrel (Osvix) has been produced. This study was conducted to evaluate the effectiveness, s...
A series of indole-based aryl(aroyl)hydrazone analogs of antiplatelet indole-3-carboxaldehyde phenylhydrazone were synthesized by the Schiff base formation reaction and their antiplatelet activity was assessed using human platelet rich plasma. The platelet concentrate was obtained using a two-step centrifugation protocol and ADP, arachidonic acid and collagen were used as inducers of platelet a...
Background: Platelets rapidly lose their qualities usually after 5 day of storage. Different standard methods have been recommended to check the quality of platelets during storage which some of them show better correlation with other quality markers during storage. The purpose of this study was to demonstrate if platelet factor 3 (PF3) assay could be an indicator of storage lesion and provide ...
Background: Major platelet adhesive receptors that contribute significantly to thrombus formation include platelet receptor glycoprotein Ibα (GPIbα) of the GPIb-IX-V complex and platelet glycoprotein VI (GPVI). GPIbα plays a crucial role in platelet tethering to sub-endothelial matrix, which initiates thrombus formation at arterial shear rates, whereas GPVI is critically involved in platelets f...
results all patients experienced improvement in the wrinkles of the side treated by the combination therapy compared to the other side. in addition, less complication was observed in the side that underwent combination therapy. conclusions our study showed that autologous fat in combination with platelet gel might have better cosmetic results as well as lesser complications in the healing of na...
this study was performed to assess the clopidogrel activity in inhibition of platelet aggregation in suspected angina patients on a daily dosag of 75 mg of clopidogrel for at least 7 days. this clinical trial was conducted in the outpatients department of cardiology, post graduate medical institute, lady reading hospital, peshawar from 15th october 2007 to 20th december 2007. we included 105 su...
background: activated normal platelets undergo many biochemical and morphological changes, some of which are apoptotic. platelet derived microparticles and shrinked platelets as hallmark of platelet activation and apoptosis disperse surfaces containing procoagulant activity around injured vessels and tissues. this study was conducted to determine microparticles formation and platelet shrinkage ...
Abstract Background and Objectives Human platelet antigens (HPAs) are polymorphic structures located on the membrane of platelets (PLTs). These antigens have important role in clinical situations like refractoriness to platelet transfusion which is the most important cause of transfusion related mortality and morbidity in patients by recurrent platelet transfusion. Alloimmunization against the...
