Figure 6: Representative photographs showing the distribution of choline acetyltransferase (ChAT) immunostaining cells in medial septum and acetylcholinesterase (AchE) reactive cells in hippocampus of CORT-induced memory impairment or CORT-injected and Sinmun (HT7) acupoint-stimulated rats. Lower magnification of the small box in panel (d) and high magnification of the big box in panel (g and j) of the same fields of AchE- stained nuclei of the hippocampus. Scale bar represents 100 μm (a), 200 μm (d) and 50 μm (g and j), respectively.
