Figure 4. Relative Caspase-3, Bcl-2 and Bax mRNA expression in cortical and hippocampal tissues of the in three groups of mice. (A) Relative mRNA expression in mouse cortex. (B) Relative mRNA expression in mouse hippocampus. The data are presented as the mean ± standard deviation (n =5). *P < 0.05 vs. Con group; # P < 0.05 vs. P8 group.
