Comparison of lumen cross-sectional capacities of the basilar artery (bottom panel). Top panel represents micrographs of the BAs obtained from the healthy controls (A), the SAH only rats (B), the vehicle-treated SAH rats (C), SAH rats received 100 ug/kg/day purpurogallin treatment (D), SAH rats received 200 ug/kg/day (E), and 400 ug/kg/day purpurogallin treatment (F). Standard bar = 200 μm. : compared with the SAH and sham operated group. : comparison between the SAH group and the controls. , : purpurogallin + SAH groups compared with the SAH group. Data are means ± SEM (/group).
