概括

通过清除活性氧物种 (ROS),Resorcimoline有效地保护大动脉手术后脊髓免受伤害. 这种新型抗氧化剂显著改善了神经功能,并减少了与埃达拉相比的发病率.

科学领域:

神经科学是一个神经科学.
心血管外科心血管外科
药理学药理学是指药理学的学科.

背景情况:

脊髓损伤 (SCI) 是大动脉手术后的一种风险,原因是缺血-再输液诱导的活性氧物种 (ROS).
抗氧化剂正在研究减轻SCI.
瑞索西摩林是一种新型抗氧化剂,具有已证明的ROS清除能力.

研究的目的:

为了评估脊髓保护效果的复苏素.
为了比较resorcimoline与临床自由基清除剂edaravone的疗效.

主要方法:

一个子SCI模型是通过下大动脉封闭诱导的.
在再输血后,动物接受了盐水液,树脂素 (6毫克/公斤) 或埃达拉 (6毫克/公斤).
评估了神经功能 (修改的塔洛夫评分),残肢发病率,神经元存活率和氧化DNA损伤.

主要成果:

与对照组相比,Resorcimoline显著改善了修改后的塔洛夫得分,并减少了的发生率.
基因组学分析显示,在用复苏醇治疗的动物中,残留的正常神经元数量更大,氧化DNA损伤减少.
与对照组相比,埃达拉没有显著的保护作用.

结论:

在大动脉手术后,Resorcimoline表现出显著的脊髓保护作用.
这些保护作用归因于resorcimoline在消除缺血-再输液产生的ROS中的强有力的抗氧化活性.

关键词:

抗氧化剂是一种抗氧化剂.缺血-再输血损伤的损伤有活性氧物种的反应性氧物种.这是一种复苏性聚合物.脊髓损伤导致的脊髓损伤

Neurogenesis and Regeneration of Nervous Tissue

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
