Fig. 4
Representative photomicrographs of HE-stained cerebral sections after 1, 6, 12, 24, and 48 h of induction of cerebral ischemia. Vacuolations in neuropil (yellow arrows), perivascular edema (blue arrows), shrinkage of neurons (dark green arrows) that increased gradually by time are seen. magnification X:400, scale bars = 50 µm. The bar chart shows the semi-quantification of the neuronal injury scores. All data expressed as means ± SE (n = 4). The different letters represent the statistical significance between different time points (P < 0.05).
