The chronic administration of 10 mg/kg/day of dipyridamole to rats produced 33.7% inhibition of platelet aggregation induced with ADP and a 93% increase in 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha) in vascular samples, versus saline-treated rats. Mopidamol, 8.3 mg/kg/day, caused 50.6% inhibition of ADP-induced platelet aggregation, 37.6% inhibition of aggregation induced with arachidoni...
Platelet aggregation and anti-inflammatory effects of garden pea, Desi chickpea and Kabuli chickpea.
Inflammation is the natural body defense mechanism for the removal of injurious agents, necrosed cells and tissues from the body. This study was aimed to evaluate the anti-inflammatory and platelet aggregation effects of three medicinal plants of Pakistan. Methanolic extract of garden pea inhibited arachidonic acid (AA)-induced platelet aggregation (IC50 = 35 microg/mL) and platelet activating ...
Recent evidence suggests that endothelium-derived relaxing factor exhibits properties of nitric oxide. Like nitric oxide, it inhibits platelet function and mediates its effects by elevating intracellular cyclic GMP. In this study we have investigated the role of reduced thiol in the mechanism of action of endothelium-derived relaxing factor on platelets. Bovine aortic endothelial cells were gro...
Background and Purpose: Epoxygenase metabolites of arachidonic acid are produced by several tissues and have been shown to inhibit in vitro platelet aggregation. The purpose of the present investigation was to determine whether 14,15or 8,9-epoxyeicosatrienoic acid, epoxygenase derivatives of arachidonic acid, affect the speed of platelet aggregation in in vivo mouse cerebral arterioles. Methods...
We have previously reported that arachidonic acid induced a biphasic pattern of platelet aggregation and the release of both dense and alpha-granule components. Low levels of arachidonate (0.025--0.1 mM) specifically induced aggregation and release, while high concentrations (0.15--0.35 mM) caused a progressive inhibition of these platelet responses in human gel-filtered platelets (GFP). We now...
AIMS Although full platelet inhibition with aspirin and thienopyridines before coronary stenting has significantly reduced the risk of acute stent thrombosis, peri-procedural myonecrosis still occurs frequently and is associated with increased death rate. Whether further inhibition of platelet aggregation by a glycoprotein IIb/IIIa antagonist may provide an additional cardioprotection is unknow...
Kami-shoyo-san (Jia-Wei-Xiao-Yao-San), Toki-shakuyaku-san (Dang-Gui-Shao-Yao-San) and Toki-shigyaku-ka-goshuyu-shokyo-to (Dang-Gui-Si-Ni-Jia-Wu-Zhu-Yu-Sheng-Jiang-Tang) are Kampo (traditional Chinese) medicines which are traditionally and effectively used for the treatment of chilly sensation (Hiesho) in Japan, but the active components and their detailed mechanisms have not yet been clarified....
Licochalcones extracted from Glycyrrhiza inflata are known to have a variety of biological properties such as anti-inflammatory, anti-bacterial, and anti-tumor activities, but their action on platelet aggregation has not yet been reported. Therefore, in this study we investigated the effects of licochalcones on platelet aggregation. Collagen and U46619, a thromboxane A2 receptor agonist, caused...
A series of novel 2-aminopyrimidine and 2-Substituted-4,6-diaminopyrimidine derivatives have been synthesized and their anti platelet aggregation activities were assessed against ADP and arachidonic acid- induced platelet aggregation in human plasma using light transmission aggregometry. None of the compounds showed satisfactory activity against the aggregation induced by ADP. However, satisfac...
