Inhibition of excitatory neurotransmission with kynurenate reduces brain edema in neonatal anoxia.
Excitatory amino acid neurotransmitters have been implicated in fostering brain edema and neuronal death in ischemia. As both of these processes are involved in nervous system damage during neonatal anoxia, the effect of blockade of cell excitation with kynurenate upon brain water was studied following anoxic-ischemic brain injury in neonatal rats. Such treatment attenuated brain edema immediately after, and 24 h following anoxia-ischemia.
