Fig. 2 — Paraffin sections were stained with anti-Aβ (4G8) and peroxidase-based labeling (brown) and counterstained with hematoxylin to visualize nuclei (violet). a In the RA group, Aβ accumulation was reduced in cortical regions in the vicinity of the amygdala. Images in bottom are the magnified view of the red circle in the upper figure. The scale bars in upper and lower showed 500 and 50 μm in distance, respectively. b Aβ plaque area per 1000 μm² of cortical regions in the vicinity of the amygdala.
