ACSF

ACSF通常用作CSF的替代物，可在脑片灌注过程中保护中间神经元 [1].

ACSF (人工脑脊液)可减少脑水肿的发生率，并进一步抑制脑细胞疾病。在神经外科领域，如颅内手术，ACSF常被用作冲洗液或灌洗液，或者当脑脊液流失时用作补充液。在科研中ACSF常用来维持pH平衡和维持组织氧输送[2，3]。

在体外急性大脑切片模型中研究神经功能的基本特征时，ACSF常用来维持氧的供给。在新皮层小鼠切片中，carbogenated ACSF处理可保持pH平衡和维持氧输送，而no-magnesium ACSF治疗的切片中出现癫痫样事件[1]。在保护神经元的靶向药物研究中，通常用ACSF处理小鼠作为对照来评估药效[3]。

也有研究指出在大鼠脑切片模型中，经ACSF（人CSF的替代物）处理可有力地促进CA1、CA3区和5层锥体神经元的自发放电[4]。
