概括
科雷克辛治疗减少了氧化应激,并在脑缺血-再输液损伤后的大脑组织中调节了骨质保护素 (OPG),RANK,RANKL和TRPC1等关键生物标志物,这表明神经保护潜力.
科学领域:
- 神经科学是一个神经科学.
- 生物化学 生化学
- 药理学 药理学是指药理学的学科.
背景情况:
- 大脑缺血-反 (I/R) 损伤与氧化应激和涉及神经元损伤的生物标志物的改变表达有关.
- 生物标志物,如骨质保护素 (OPG),核因子 κ-B (RANK) 的受体激活剂,它的配体 RANKL,以及短暂受体潜能佳能 1 (TRPC1) 在神经保护和炎症中发挥作用.
- 抗氧化剂治疗可能会影响这些神经保护生物标志物的表达.
研究的目的:
- 为了研究Cortexin对脑I/R损伤后脑组织中OPG,RANK,RANKL和TRPC1的表达的影响.
- 评估Cortexin对血清中氧化应激标志物 (总氧化剂状态-TOS和总抗氧化剂状态-TAS) 的影响.
主要方法:
- 雄性Wistar白色大鼠遭受了缺血或I/R损伤,并接受了不同剂量的Cortexin治疗.
- 大脑和血清样本是在受伤后的第8天收集的.
- 免疫组织化学用于评估大脑组织中的生物标志物表达,ELISA用于测量血清TOS和TAS水平.
主要成果:
- 与对照组相比,缺血和I / R组表现出显著增加的TOS和减少的TAS.
- 皮质素治疗显著降低了TOS和增加了TAS,更高的剂量恢复了TAS超过控制水平.
- 在缺血和I/R组中,OPG,RANK,RANKL和TRPC1的表达显著升高,而Cortexin治疗显著降低了它们的表达.
结论:
- 科雷克辛在脑I/R损伤中显示出潜在的神经保护作用.
- 这些效应似乎通过调节氧化应激和参与炎症和信号的关键生物标志物来调节.
- 科尔特辛能够降低氧化应激并使生物标志物表达正常化的能力表明它具有有前途的治疗作用.

01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
