根据全脑短暂性缺血和再灌注对小脑皮质的影响和损害的实验要求，我们选用家兔制作动物模型，使家兔全脑断血就应同时阻断双侧颈总动脉和推动脉的血液供应。颈总动脉位置较浅，易分离，推动脉位置较深五周围组织结构复杂。能否成功分离和阻断推动脉就成为本模型制作的关键。目?
According to the experimental and experimental requirements on the effects of transient global cerebral ischemia and reperfusion on the cerebellar cortex, we selected rabbits to make animal models so that when the whole brain is severed, the rabbits should both block the common carotid artery and the artery Blood supply. Carotid artery shallow, easy to separate, push the pulse position deeper around the five complex organizational structure. The success of the separation and blockade of the impetus has become the key to this model. Head
