据文献报道,谷氨酸盐(?)LU)被认为是中枢神经系统兴奋性突触最重要的神经递质,又被列为内毛细胞与耳蜗神经节(CG)神经元间突触的主要替补递质。而且CG神经元对谷氨酸盐拮抗剂的兴奋毒性效应是敏感的,在用KA(kainic acid)或AMPA行外淋巴灌注时,CG神经元外周末梢会明显肿胀,这些损害已知与缺血或缺氧时所造成的神经损伤有关,根据这种理 It has been reported in the literature that glutamate (? LU) is considered to be the most important neurotransmitter of the excitatory synapse of the central nervous system and is also listed as a synapse between inner hair cells and cochlear ganglion (CG) neurons The main substitute delivery. Moreover, CG neurons are sensitive to the excitotoxic effect of glutamate antagonists. Peripheral lymphatic perfusion with KA (kainic acid) or AMPA causes significant swelling of the periphery of CG neurons, which are known to be associated with ischemia Or hypoxia caused by nerve damage, according to this theory
