Analysis of activated microglia/macrophages in penumbra 72 h, 7 days, and 14 days after MCAO (n = 6 of each group). Activated microglia/macrophages were stained for CD68 in control (a–c) and DMF treated (d–f) MCAO rats, and cell number was quantified (g). iNOS staining was also used to demonstrate activated microglia/macrophages at 72 h (h, i, arrows). *p < 0.05, **p < 0.01, Mann-Whitney U test
