Double immunofluorescence labeling of nuclear factor kappa B (NF-κB) in hippocampus of control, lipopolysaccharide (LPS)-treated, and LPS and baicalin (Bac) co-treated animals (a-c). NF-κB and DAPI-positive cells in hippocampal CA1, CA2 and CA3 region (d). Data (n = 5) are shown as mean ± S.E.M. Scale bar = 100 μm. * p < 0.05 vs. control animal, # p < 0.05 vs. LPS-treated animal
