a Examples of Iba-1 immunoreactivity in macrophages of rats at 2 weeks in aged (18 months) IVH, young (3 months) IVH, aged control and young control groups. The number of Iba-1 positive cells was quantified relative to the number of choroid plexus epithelial cells. Values are mean ± SD; n = 13 in young and aged IVH groups and n = 6 in young and aged control groups. #p < 0.01 aged vs. young IVH groups by Student t test. Scale bar = 100 µm (upper row) and 20 µm (lower row). b Examples of CD68 immunoreactivity in macrophages of rats at 2 weeks in aged IVH, young IVH, aged control and young control groups. The number of CD68 positive cells was quantified relative to the number of choroid plexus epithelial cells. Values are mean ± SD; n = 13 in young and aged IVH groups and n = 6 in young and aged control groups. #p < 0.01 aged vs. young IVH groups by Student t test. Scale bar = 100 µm (upper row) and 20 µm (lower row)
