Effect of treatment with the raf inhibitor SB386023-b in cerebral arteries on the protein levels of pERK1/2 after SAH. There are increased expressions of the pERK1/2 protein levels in the SAH compared to the sham operated rats. Treatment with SB386023-b after 6 h prevented the increased protein expression. Data are presented as the pERK1/2/β-actin mean optical density ratio relative to control. Data are expressed as mean ± s.e.m. * P ≤ 0.05.
