A single episode of moderate hypoglycemia does not induce oxidative injury in the hippocampal CA1 dendritic area. (A) Fluorescent images show MAP2 (green) and 4HNE (red) antibody stained stratum radiatum (SR) of hippocampal CA1 area. The 4HNE intensity in the dendritic area after a single episode of moderate hypoglycemia (M-HG) is almost identical between non-diabetic (saline treated) and diabetic rats. SP, Stratum pyramidale. Bar = 100 μm. (B) Bar graph represents quantitated 4HNE fluorescent intensity from the SR area of hippocampal CA1 area. Data are mean + s.e.m.; n = 5.
