GFAP staining is decreased in mice exposed to arsenic.

<p><b>A & B</b>. Staining on brain sections (A, control; B, arsenic exposed) using anti-GFAP antibody was used as a marker for astrocytes. Representative pictures illustrate the difference in GFAP staining in hippocampal area of control and arsenic treated mice. <b>C</b>. For graphical presentation, the intensity of staining in cortex and hippocampus was quantitated as explained in the methods. Analysis is by t-test. N = 7–8 mice per group.
