Effects of Bioactive TBK-SE on GFAP and Iba-1 expression. The immunohistochemical analysis for GFAP showed that positive staining for GFAP was observed in the tissues obtained from CIR rats both in brain (a) as well as in cerebellum sections (b). In contrast, a reduction of GFAP positive staining was evident in bioactive TBK-SE-treated group in both two different areas (c and d). By western blot analysis it has been shown a significant increase Iba-1 expression in cerebellum samples collected from CIR rats seven days after CIR induction. Conversely, levels of Iba-1 were attenuated by administration with bioactive TBK-SE attenuated Iba-1 levels by approximately 50 % (e). GAPDH was used as internal control. **p < 0.05 vs CIR
