FIGURE 2

Sepsis-induced encephalopathy enhanced microgliosis and neuronal degeneration. H&E-stained sections of the different brain regions showing darkly-degenerated, apoptotic neurons (arrows) and glial cell proliferation (circles). The dentate gyrus shows marked microgliosis (g). The insets in the cerebral cortex show a picture of subependymal microgliosis in the CLP 24 h groups, and foci of focal cortical microgliosis in the CLP 72 h groups. Meningeal congestion (M) is also observed in the cerebral cortex of the CLP 24 h group. The blood capillaries (C) exhibit interruption of their endothelial lining with widening of Virchow Robin’s (perivascular) space.
