Neuroprotective effects of apocynin in the cerebral cortex and hippocampus(CA1 and CA3 regions) following TBI.

<p><b>A:</b> Representative Cresyl violet staining on day 4 after TBI from sham, saline- and apocynin-pre/post treated mice. Boxed areas in left column are shown at higher magnification in right columns. <b>B:</b> Quantitative analysis of the numbers of surviving cells expressed as % of sham control. Intact cells showing round nuclei but not condensed, pyknotic nuclei were counted as surviving cells. Data are mean ± SE (n = 5–7) and a typical experiment is presented. <i>^*P</i><0.01 vs. saline in each group. Scale bars, 50 µm.
