The effect of Arctigenin on the change ET-1in CSF after the induction of SAH (ELISA). Arctigenin dose-dependently attenuates ET-1 in the SAH rats, when compared with the SAH group. Data in the figure are presented as mean ± SD (). , compared between the Sham-operated and the SAH group; , and # when compared with the SAH + vehicle group.
