Article Title: Quercetin improves blood-brain barrier dysfunction in rats with cerebral ischemia reperfusion via Wnt signaling pathway

Figure Lengend Snippet: Experimental protocol diagram. Forty-eight male SD rats were randomly divided into 4 groups (n = 12 each): Sham, I/R, Q and Q+DKK group. At 30 min before ischemia/reperfusion (red arrow), intracerebroventricular injections were performed. DKK-1 and NS were given respectively. At 24 h after reperfusion, neurological assessment of the rats was performed using NDS. Then the rats were sacrificed and the brains were harvested for HE staining, NeuN staining and detection of brain water content (BWC). BBB ultrastructure and permeability were examined by transmission electron microscopy (TEM) and Evans blue (EB) extravasation, respectively. Western blot, RT-PCR and immunohistochemical analysis were performed for the relevant key factors of Wnt signaling pathway.
