[Abstract]  Chronic cerebral hypoperfusion (CCH) is an important risk factor of vascular dementia (VaD) and Alzheimer’s disease (AD). Hypoxia/ischemia in the whole brain induced by CCH causes serious damage to brain structure and function, which can lead to cognitive impairment. Two-vessel occlusion (2-VO), also known as permanent, bilateral common carotid artery occlusion, is one of the most widely used animal models (e.g., rat) of CCH to investigate the mechanisms of neurodegenerative processes. In this protocol, we present the surgical procedure for 2-VO in rats. [摘要]  慢性脑低灌注(CCH)是血管性痴呆(VaD)和阿尔茨海默病(AD)的重要危险因素。 CCH诱导的全脑缺氧/缺血对脑结构和功能造成严重损伤,导致认知损害。 双血管闭塞(2-VO)也称为永久性双侧颈总动脉闭塞,是CCH最广泛使用的动物模型之一( eg ,大鼠) 神经退化过程。 在这个协议中,我们介绍了2-VO在大鼠的手术过程。

【背景】许多神经和精神疾病是由脑循环障碍引起的。脑血流突然中断可导致中风,而连续性脑血流量(CBF)逐渐减少则损害记忆过程,并导致痴呆的发生(Farkas and Luiten,2001; Matsuda,2001; de拉托雷,2002年)。在2-VO大鼠模型中,在急性缺血期(术后2-3天)脑CBF显着降低,皮质和白质区血流减少最多,达35% -45%的控制水平(Otori等人,2003年)。在慢性缺血期(术后1-3个月),CBF值在1周开始逐渐恢复,但在2-VO诱导后4周仍显着低于对照值(Schmidt-Kastner等,et al 2001; Otori等人,2003; Tomimoto等人,2003)。已经报道了8周至3个月的2-VO之后,只有轻微的减少或几乎没有减少的流量(Otori等人,2003)。最后,在2-VO 6个月后,CBF几乎完全恢复正常(Choy et ...
