Fig. 1. Cytotoxicity effects for 6 h of IH or 6 h of SH in our model of blood-brain barrier measured by a MTT assay (A) and LDH activity method (B). Values are presented as mean value ± SEM (n=6, N=2 for MTT assay and n=10, N=2 for LDH activity). SH: sustained hypoxia, IH: intermittent hypoxia, control: normal atmospheric gas pressure.
