摘要

目的 :研究表没食子儿茶素没食子酸酯(epigaloctechin-3-gallit

EGCG)对脊髓损伤(spinal cord injury

SCI)大鼠炎症因子的释放及神经营养因子表达的影响。方法 :建立大鼠脊髓半切SCI模型。SCI大鼠给予EGCG治疗24 h后取血清和受损伤脊髓局部组织。ELISA法测定血清白介素-6(IL-6)、白介素-8(IL-8)含量;Western blot法测定脊髓组织neurotrophin-3(NT-3)、brain-derived neurotrophic factor(BDNF)蛋白表达。结果 :与模型组比较

EGCG能显著降低SCI大鼠血清炎性因子IL-6、IL-8的浓度

促进脊髓组织内源性NT-3、BDNF表达。结论 :EGCG可抑制炎症因子释放

增加内源性神经营养因子表达。

Abstract

Objective: To investigate the the protective effects of Epigallocatechin-3-gallate(EGCG) on the release of inflammatory cytokines and expression of neurotrophic factors in spinal cord-injuried(SCI) rats. Method: SCI model was reproduced by hemisection

and EGCG was administered for 24 h after hemisection 5 min after SCI. The concentrations of serum IL-6 and IL-8 were measured by ELISA assay

and the expression of neurotrophin-3(NT-3)and brain-derived neurotrophic factor(BDNF)protein in injured spinal cord tissues were determined by western blot. Result : EGCG significantly reduced the levels of serum IL-6 and IL-8

and increased expression of NT-3 and BDNF at the injured spinal cord in SCI rats. Conclusion : EGCG may protect against spinal cord from injury by inhibiting release of inflammatory cytokines and enhancing the expression of endogenous neurotrophic factors in SCI rats.
