摘要
为探讨继发于蛛网膜下腔出血后的迟发性脑血管痉挛的发病机制,采用兔枕大池二次注血法复制蛛网膜下腔出血模型,用经颅多普勒监测脑基底动脉血管痉挛的发生情况,实验前、后分别检测外周血中TNF含量。结果显示实验组动物迟发性脑血管痉挛的发生率达84.62%,实验第7d外周血中TNF含量较实验前升高(P<0.01)。结果表明:在蛛网膜下腔出血后脑血管痉挛的形成中确有免疫因素的参与。
The purpose of this study was to investigate the etiopathology of delayed cerebral vasospasm following subarachnoid hemorrhage(SAH).In this study two injections of autologous blood were made into the cisternal magna of the rabbit to produce models of SAH.The transcranial doppler ultrasound was used to monitor the occurence of cerebrovasospasm.The tumor necrosis factor (TNF) in the blood was examined before and after the experiment.The results obtained showed the level of TNF was higher after experiment than that before ( P <0 01),and the morbidity of delayed cerebral vasospasm was 84.62% in the experimental group.This study indicates that the delayed cerebral vasospasm following SAH is elicited via an immunoreaction.
