摘要

重组中性粒细胞抑制因子(NIF)在大鼠大脑中动脉(MCA)暂时性(2小时)封闭的情况下,采用腔内缝合技术评估其神经保护作用。在再灌注开始后和mca闭塞后4和6小时立即给予NIF (1.5 mg/kg,静脉注射)可显著减少双脑半球梗死体积(P<0.001)和脑肿胀(P<0.001),神经预后改善(P<这些结果表明,NIF在一过性局灶性脑缺血大鼠模型中具有显著的神经保护作用

Neuroprotective Effect of Recombinant Neutrophil Inhibitory Factor in Transient Focal Cerebral Ischaemia in the Rat

The neuroprotective effects of recombinant neutrophil inhibitory factor (NIF) have been assessed with temporary (2 h) middle cerebral artery (MCA) occlusion in the rat using the intraluminal suture technique. Administration of NIF (1.5 mg/kg, i.v.) immediately after the onset of reperfusion and at 4 and 6 h post-MCA occlusion significantly reduced both hemispheric infarct volume (P< 0.001) and brain swelling (P< 0.001), and improved neurological outcome (P< 0.02) when assessed at 24 h. These results demonstrate the marked neuroprotective efficacy of NIF in a rat model of transient focal cerebral ischaemia
