[0056] Animal Model Establishment of Acute Focal Cerebral Ischemia

[0057] Male SD rats with a body weight of 250-270 g were used, referring to the large scale established by Zea Longa et al. (Longa EZ, Weinstein PR, Carlson S, Cummins R. The method of occluding the middle cerebral artery of rats with a suture was injected intraperitoneally with 400 mg / kg of 10% chloral hydrate solution to anesthetize the animal. Rats were fixed in the supine position, the skin was incised in the middle of the neck, and all layers of tissue were bluntly separated to expose the right common carotid artery (CCA). After the bifurcation of the internal carotid artery (ICA) and external carotid artery (ECA), it was separated carefully to avoid damage to the vagus nerve and trachea, and the line was placed for use. The ipsilateral external carotid artery was separate...
