Photomicrographs of the hippocampal subregions in different groups of rats immunostained for Iba1 to label reactive microglia. Note the presence of reactive microglia (Arrow) in large number in AD group in all regions and their distribution is less dense in AD+NAC group (photomicrographs of sham and AD+NAC 50 groups are avoided for simplicity). Scale bar= 25μ, in CA1-CA4 regions, =15μ in dentate gyrus (DG).
