1 MHT对实验动物缺血性脑损伤的保护作用 许多学者通过重复试验均证实,在缺血后给予亚低温治疗能减少梗塞灶面积,减轻脑神经元结构的破坏。若在短暂脑缺血后1小时开始亚低温治疗,并持续24h,甚至可使海马CA1神经元几乎全部得到保护。不同脑区对亚低温的敏感性不同,在全脑模型中,海马CA1区受损程度随亚低温的度数降低而呈线 1 MHT protective effect of experimental animals with ischemic brain injury Many scholars confirmed by repeated tests, in the ischemic hypothermia treatment can reduce infarct size, reduce the damage of cerebral neuronal structure. If mild hypothermia was started 1 hour after transient cerebral ischemia and continued for 24 h, almost all of the neurons in the hippocampal CA1 were protected. Different brain regions have different sensitivities to mild hypothermia. In the whole brain model, the degree of damage in hippocampal CA1 region was linear with the decrease of the degree of mild hypothermia
