A is Iba1 immunostaining, showing microglia in the corpus callosum, somatosensory and retrosplenial cortices. In the vanadium group, note the increase in the number of the microglia, and the bigger cell body. Scale bar =50 μm (constant for all micrographs). B are the graphs showing the Iba1+ microglia counting in the corpus callosum, and Iba1+ percentage area covered in the cortices. Groups – Ctrl (water); V (Vanadium 3 mg/kg); V + M10 (Vanadium 3 mg/kg + MIMO2 10 mg/kg); M10(MIMO2 10 mg/kg). Number of mice per group = 5. (*p < 0.05, **p < 0.01, ***p < 0.001).
