研究表明,血小板功能异常参与脑梗死的发生和发展,是脑梗死促发因素之一,也是造成脑梗死后缺血性损害加重的主要原因之一[1]。这些研究多集中在血小板膜糖蛋白及超微结构的变化方面。为此我们对160例急性脑梗死患者血小板计数(ＢＰＣ)及平均血小板体积(ＭＰＶ)进行动态观察,以 Studies have shown that abnormal platelet involvement in the occurrence and development of cerebral infarction is one of the causative factors of cerebral infarction, but also one of the main causes of ischemic damage after cerebral infarction [1]. Most of these studies focus on the changes of platelet membrane glycoproteins and ultrastructure. To this end, we performed dynamic observation of platelet count (BPC) and mean platelet volume (MPV) in 160 patients with acute cerebral infarction
