Fig. 5From: Repositioning drugs for traumatic brain injury - N-acetyl cysteine and PhenserineCultured hippocampal neurons in triplicate were prepared from 18 to 20 day rat (Sprague Dawley) embryos and were cultured for 7 days. They were treated with (−)-Phen (5 uM) followed by addition of an excitotoxic concentration of glutamate (50 uM). Neuronal viability was assessed 24 h after addition of glutamate (MTS assay). The results are plotted as percent neuronal survival ± SEM [58]Back to article page
