当流向整个大脑的血液短暂受阻时,就会发生全球脑缺血,这会导致迟发性的神经功能障碍。在这里,我们提出了一种实施四血管阻塞大鼠模型的方案,以研究与全球缺血相关的神经退行性变和认知缺陷。我们描述了实施椎动脉和颈总动脉闭塞的步骤,以实现对脑血流的充分阻断。然后,我们使用组织学分析和行为测试来详细说明预期结果。有关本议定书的使用和执行的完整细节,请参阅Chung等人。(2022年)。椎动脉闭塞的优化技术细节颈总动脉短暂闭塞的分步程序使用扩瞳出版商的说明对缺血情况的程度进行评分:进行任何实验方案都需要遵守当地实验室安全和伦理的机构指南。当流向整个大脑的血液短暂受阻时,就会发生全球脑缺血,这会导致迟发性的神经功能障碍。在这里,我们提出了一种实施四血管阻塞大鼠模型的方案,以研究与全球缺血相关的神经退行性变和认知缺陷。我们描述了实施椎动脉和颈总动脉闭塞的步骤,以实现对脑血流的充分阻断。然后,我们使用组织学分析和行为测试来详细说明预期结果。
Global cerebral ischemia occurs when blood flow to the entire brain is transiently blocked, which results in delayed neurologic deficits. Here, we present a protocol for performing the four-vessel occlusion rat model to study the neurodegeneration and cognitive deficits associated with global ischemia. We describe steps for carrying out the vertebral and common carotid artery occlusion which enables sufficient blockage of cerebral blood flow. We then detail expected outcomes using histology assays and behavioral tests. For complete details on the use and execution of this protocol, please refer to Chung et al. (2022). Details of optimized techniques for the vertebral artery occlusion Step-by-step procedures for transient occlusion of the common carotid arteries Instructions for scoring the degree of ischemic condition with the pupil dilation Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
