Both iNOS and NF-κB expressions showed stronger bands in the stroke 1-day group than in the sham 1-day group (n = 7, p < 0.001; Figures 3(d) and 3(e)), and the levels in the stroke 7-day group were still higher than those in the sham 7-day group, but lower than those in the stroke 1-day group (n = 7, p < 0.001; Figures 3(d) and 3(e)). Here, NOS2 is linked to Stroke.
