Cell apoptosis in the cerebral frontal cortex in rats following chronic cerebral ischemia (TUNEL staining).

(A) Representative photomicrographs of TUNEL-positive cells in rats in the sham and ischemia groups at 3, 6, 9 weeks (wk) after surgery (200×). Arrows showed TUNEL-positive cells. (B) The number of TUNEL-positive cells/200-fold field in the frontal cortex. Data are presented as the mean ± SD and analyzed using one-way analysis of variance and the Student's t-test. *P < 0.05, vs. sham operated (sham) group; #P < 0.05, vs. ischemia group.
