Fig. 4From: Short-term auricular electrical stimulation rapidly elevated cortical blood flow and promoted the expression of nicotinic acetylcholine receptor α4 in the 2 vessel occlusion rats modelThe immunohistochemical staining of the ChAT in the hippocampal CA2 output cortex. The ChAT immunoreactive cells were marked by arrowhead a in 400X and the counts of ChAT immunoreactive cells had no significant difference in each group; b ChAT was recognized in the hippocampal CA2 output cortex. (75 X 75 μm, scale bar = 50 μm); c Data represent mean ± SD in the counts of ChAT immunoreactive cells (n = 6); d The levels of ChAT in western blot analysis; e Data represent mean ± SD in the western blot levels of ChAT (n = 3)Back to article page
