FIGURE 6. Localization of microglial cells and morphology using tomato lectin staining in control kits and in kits exposed to 20, 30, and 40 µg/kg of endotoxin. Microglial cells are seen in corpus callosum, along inferior border of lateral ventricle (A), around angle of lateral ventricle (B), in area of internal capsule (C), between 2 fields of hippocampus (D), and in fimbria hippocampus (E). Increase in density of microglial cells is observed in endotoxin-treated groups compared with control group. In all of these regions, microglial cells are ramified in control group and become less ramified/bushy, amoeboid, and round in endotoxin-treated groups. E. = endotoxin; LV = lateral ventricle; CC = corpus callosum; IC = internal capsule; Fi = fimbria hippocampus. Scale bar = 200 µm.
