Caspase 3 activation in rat hippocampus after TBI.

<p>(A) Western blot analysis of procaspase 3 and cleaved caspase 3 in hippocampus. β-actin served as loading control. Relative protein expression levels were determined by normalizing band density of procaspase 3 (B) or cleaved caspase 3 (C) to that of β-Actin and comparing with sham group. Data are presented as mean ± SEM. N = 5. *<i>P</i><0.05 and **<i>P</i><0.01 <i>vs.</i> sham group.
