The apoptosis rate of primary neurons injured by OGD at different concentrations of RA. a Flow cytometry for apoptosis in primary hippocampal neurons after 0~ 40 μmol/L RA treatment. b A comparison of apoptosis rates for different concentrations of RA. The data are expressed as the means ± SEM, N = 5, *P ≤ 0.05, **P ≤ 0.01
