No difference in NPC death 24 h after discontinuation of propofol treatment.

A bar graph showing the proportion of dead NPCs in wells treated with either 2.5 or 5 μg/mL of propofol, 24 h after discontinuation of treatment as noted. Cell death was quantified with PI staining. There were no differences in NPC death at both concentrations compared to control treatment 24 h after discontinuation of propofol. Data are presented as mean ± S.E.M and expressed as percent of the control value (N = 3 per condition; P = 0.52 and 0.45 for the 4 and 24 h treatment groups, respectively, with 1-way ANOVA).
