Microglial ultrastructure in the ischemic penumbra microglial ultrastructure was detected after ischemia by transmission electron microscopy (uranyl acetate-lead citrate staining, 15000×). (a) TTC staining of the rat brain. The frame represents the location of the cortical samples. (b) Microglial ultrastructure in the sham surgery group was normal. Structures within the mitochondria (arrow) were intact. Mitochondria (arrows) were obviously swollen in the 2 h model group (c) and the 1 d model group (d), and even the palate partially disappeared in 3 d model group (e). Lysosomes (arrows) were scattered in the 2 h electroacupuncture group (f), 1 d electroacupuncture group (g), and 3 d electroacupuncture group (h).
