Blood-brain barrier (BBB) disruption and neural apoptosis are thought to promote early brain injury (EBI) after subarachnoid hemorrhage (SAH). Previous studies have demonstrated that valproic acid (VPA) decreased brain injury in a prechiasmatic injection model of SAH in mice. It should be noted that the beneficial effects of VPA and the underlying mechanisms have not been fully elucidated. ⋯ BBB, blood-brain barrierEBI, early brain injuryHSP, heat shock proteinMMP, matrix metalloproteinasePBS, phosphate-buffered salineSAH, subarachnoid hemorrhageTUNEL, terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labelingVPA, valproic acid.
