HBHP decreased the BBB permeability in tPA-treated MCAO rats. a Representative images of Evans blue leakage from 4.5 h MCAO rats. The contents of Evans blue leakage were measured and expressed as microgram per gram brain. *P < 0.05, **P < 0.01; n = 4–6. b Immunofluoresence staining with IgG antibody (red) in the cerebral cortex and striatum from 4.5 h MCAO rats. The leaked IgG was quantified. Scale bar = 200 μm. **P < 0.01, n = 3–4. c Western blot and quantified data of occludin in ischemic ipsilateral hemispheres from 4.5 h MCAO rats. *P < 0.05, **P < 0.01; n = 4. Data were shown as mean ± SD
