缺血性中风的血小板活性的大小仍不清楚,以前的报告也不一致,中风伴有的各种因素能够激活血小板,因此作者检查了缺血性中风的不同类型病人的血小板活性。 β—凝血酶原(BTG)是一种从有活性的血小板中释放入血循环中的血小板特性蛋白质,己把血浆BTG浓度作为血小板活化的明显的指标。颈内动脉和肘静脉血浆中β—凝血酶原的血浆浓度比率作为估价脑循环中血小板活性的指标,作者测定了75例对照组和186例不同类型缺血性中风的病人血浆BTG浓度,确定颈内静脉(A)和从肘静脉(B)血浆中BTG浓度比率,缺血性中风包括:腔隙性动脉血栓
The magnitude of platelet activity in ischemic stroke remains unclear and previous reports are also inconsistent. Various factors associated with stroke activate platelets, so the authors examined platelet activity in different types of patients with ischemic stroke. Beta-prothrombin (BTG), a platelet-specific protein released into the bloodstream from active platelets, has taken plasma BTG concentrations as a significant indicator of platelet activation. Plasma concentrations of β-prothrombin in the internal carotid artery and cubital vein plasma were used as an index for assessing platelet activity in the cerebral circulation. The authors determined plasma BTG concentrations in 75 control subjects and 186 patients with different types of ischemic stroke The ratio of BTG concentrations in the jugular vein (A) and from the cubital vein (B) plasma, including ischemic stroke
