(A): Representative TTC-stained sections of vehicle- and tropisetron-treated rats at 24 h following permanent middle cerebral artery occlusion (pMCAO). Tropisetron or vehicle was given intraperitoneally 30 min before pMCAO. (B): Total, cortical and subcortical infarct volumes assessed at 24 h in control (vehicle) and tropisetron groups. No significant effect of tropisetron on cerebral infarction was found.
