NAP protects from cell death in a dose dependent manner following 2 hours of OGD insult, but not after additional 24 hours reperfusion. Primary neuronal cultures (5-6DIV) were subjected to 2 h of ischemic insult. Cell viability was evaluated using MTS viability assay. Data was normalized to % of control. Results are shown as . *Significantly different from OGD with no NAP, M, M, M (3 independent experiments are summarized, ANOVA, with post hoc Scheffe, significant difference considered to be ). Using LSD post hoc, NAP M (+), M are significantly different from the OGD group ).
