Effect of minocycline on caspase-3 expression in the hippocampal CA1 region of rats after cerebral ischemia-reperfusion (I/R) (immunohistochemical staining, × 200).
Caspase-3-positive cells were not observed in the sham-operation group; the number of caspase-3-positive cells in the minocycline group was significantly less than in the I/R group. Arrows point to caspase-3-positive cells.
