The mean gene expression levels of amyloid protein precursor (APP) in the hippocampus CA3 area in rats 2 (n = 14), 7 (n = 8), and 30 (n = 8) days after 10-min global brain ischemia. Marked SD, standard deviation. Indicated statistically significant differences in levels of gene expression between 2 and 7 (z = 3.498, p = 0.0014) and between 7 and 30 (z = 3.467, p = 0.0015) days after ischemia (Kruskal-Wallis test). *p ≤ 0.01
