Résumé

Objective To explore the relationship between the dynamic change of plasma tissue-type plasminogen activator(t-PA)and its inhibitor-1(PAI-1)levels and infarct size in patients with acute cerebral infarction.Methods There were 100 patients with acute cerebral infarction,22 cases of large area infarction,36 cases of small area infarction,42 cases of lacunar infarction.The levels of plasma t-PA or PAI-1 in 24 h,2 d,14 d,21 d after cerebral infarction were detected by chromogenic substrate method,compared with normal control and the level of blood plasma t-PA or PAI-1 in patients with different size of cerebral infarction.Results Compared with normal control,levels of plasma t-PA at 24 h,2 d,14 d after acute cerebral infarction decreased significantly,and plasma PAI-1 level increased significantly(all P0.05).The plasma t-PA level in patients with large size of infarction was lower obviously than that in patients with small area infarction and lacunar infarction,small size of infarction was lower than that in lacunar infarction(all P0.05).Conclusion The plasma t-PA level decreased and PAI level increased in patients with acute cerebral infarction.The the size of infarction area is larger,the plasma t-PA level is lower,but there is no relationship between the plasma PAI-1 level and infarction area.
