The relativity of the activity change of tissue-type plasminogen activator and type 1 plasminogen activator inhibitor in patients with cerebral infarction and defect of nerve function

摘要

AIM:To explore the dynamic changes of the activity of tissue type plasminogen activator (t PA) and type 1 plasminogen activator inhibitor (PAI 1)and its clinical significance by observing the activity of t PA and PAI 1 in patients in acute and recovery phases of arteriosclerotic cerebral infarction.METHODS:Testing the activity of plasma t PA and PAI 1 of 91 patients with arteriosclerotic cerebral infarction and 80 healthy old ages by Chromgenic substrate methods and controlling them.RESULTS:The activity of t PA in acute and recovery stage of arteriosclerotic cerebral infarction patients were apparently lower than that of control and the activity of PAI 1 were higher than that of control.Volume of cerebral infarction was negatively related to the activity of t PA and positively related to the activity of PAI 1. CONCLUSION:The plasma fibrinolytic activities of the acute and recovery stage patients with arteriosclerotic cerebral infarction declined.
