[Abstract] ObjectiveTo observe the relationship between plasma content of endot helin_1(ET_1) and its risk factors in patients with acute cerebral infarction (A CI). MethodsThe levels of plasma ET_1, serum cholesterol, triglyceride, low den sity lipoprotein, high density lipoprotein and blood sugar were measured in 120patients with ACI (within 72 hours of onset) and 84 normal healthy subjects. TheEuropean Stroke Scale (ESS) was used to evaluate neurological deficit for ACI p atients.ResultsACI patients had significantly higher level of plasma ET_1 com pared with normal control subjects [(183.27±56.63)pg/ml versus(156.47±34. 24)pg/ml, P<0.05], but there was no correlation between plasma ET_1 conce ntration an d hypertension, diabetes mellitus, serum cholesterol, triglyceride, low densitylipoprotein, high density lipoprotein or ESS(all P>0.05).ConclusionsIncreased ET_1 level in plasma in early stage of ACI suggests that it may be inv olved inthe development of cerebral infarction. But the relationship between plasma ET_ 1 and common ischemic stroke risk factors is still unclear.

血浆内皮素(ET)是血管内皮分泌的一种缩血管活性因子，ET在缺血性脑血管病的发生、发展 中起重要作用[1～3]。ET有三种异构体：ET_1、ET_2和ET_3，其中ET_1收缩血管作 用最强、效应最持久，监测血浆ET_1能帮助判断病情变化和评估预后。本文 对急性脑梗死(ACI)患者血浆ET_1的改变及其与卒中常见危险因素的关系进行观察，探讨ET_ 1在ACI发病机制中的作用。
