Effects of Exo/miR-193b-3p treatment on neurological behavioral impairment, brain edema, BBB injury, and neurodegeneration in SAH mice. a Evaluation of neurological scores in each group (n = 18). b Alterations in brain water content in each group (n = 6). c, d FJC staining and the number of FJC-positive cells in every square millimeter of brain tissue. The upper panel (only first row) with boxes represented lower magnification images, and the other images represented higher magnification images from the boxes in the first row. Scale bars = 20 μm. e Quantitative analyses of Evan’s blue dye extraversion (n = 6). All quantitative data are presented as mean ± SD (*p < 0.05, **p < 0.01, ***p < 0.001, and NS: not significant)
