WebKetamine inhibited phosphoinositide breakdown and intracellular Ca2+ mobilization in human platelets stimulated by collagen. Ketamine (200 and 350 μM) significantly inhibited thromboxane (Tx) A2 formation stimulated by collagen. Moreover, ketamine (200 and 350 μM) increased the fluorescence of platelet membranes tagged with diphenylhexatriene. WebFeb 23, 2016 · We measured urinary 11-dehydrothromboxane B2 (TXB2), a stable metabolite of TXA2, with mass spectrometry. Samples were obtained from 977 cases and 1022 controls at time of recruitment.

WebPlatelet-activating factor (PAF), a biologically active lipid transmitter, induces platelet activation upon binding to the PAF receptor. Recent studies have found that PAF is associated with gamma-glutamyl transferase, which is an indicator of liver disease. Moreover, PAF can stimulate hepatic lipid synthesis and cause hypertriglyceridaemia. WebPlatelet activating factor (PAF), a phospholipid mediator, is a strong platelet activator and human platelets show high affinity binding sites for this agonist. It also en-hances adhesion of platelets to the endothelium in the presence of activated leukocytes[2]. It is also known as a potent stimulator of thromboxane A2 (TXA2) pro-
