依达拉奉对大鼠短暂性全脑缺血后海马CA1区的保护作用及对颗粒下区神经发生的影响
Pre- and post-treatment with edaravone protects CA1 hippocampus and enhances neurogenesis in the subgranular zone of dentate gyrus after transient global cerebral ischemia in rats
依达拉奉在临床上被用于急性脑梗塞的治疗，然而，其对脑缺血后海马神经发生的影响仍不清楚。本研究通过制作大鼠短暂全脑缺血模型观察缺血前后依达拉奉处理对海马颗粒下区神经干/祖细胞的影响。雄性大鼠随机分为3组：假手术组（n=15），对照组（n=15）和依达拉奉处理组（n=15）。采用5-溴脱氧尿嘧啶核苷（BrdU）标记增殖细胞。缺血后7,14,21天的神经发生采用免疫组化染色方法检测。细胞凋亡采用TUNEL染色法检测。结果显示依达拉奉能够增加海马神经发生，减少海马神经干/祖细胞凋亡。
Edaravone is clinically used for treatment of patients with acute cerebral infarction. However, the effect of edaravone on neurogenesis in the hippocampus following ischemia remains unknown. In the present study, we explored whether pre- and post- treatment of edaravone had any effect on neural stem/progenitor cells (NSPCs) in the subgranular zone (SGZ) of hippocampus in a rat model of transient global cerebral ischemia. Male Sprague-Dawley rats were divided into 3 groups, sham-operated (n = 15), control (n = 15), and edaravone-treated (n = 15) groups. Newly-generated cells were labeled by 5-bromo-2-deoxyuridine (BrdU). Immunohistochemistry was used to detect neurogenesis in the SGZ at 7, 14 and 21 d following ischemia. Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) was used to detect cell apoptosis. Our results indicate that pre- and post-treatment with edaravone enhances neurogenesis and protects NSPCs from apoptosis in the hippocampus.?
