Early Brain Injury, rather than Cerebral Vasospasm, has been demonstrated to be more important for patients with Subarachnoid hemorrhage. It is considered that allicin can make sense in a wide range of pharmacological areas and can be taken as a therapeutic method in many pathologic situations. We have explored the potential effect of allicin and possible mechanisms in Early Brain Injury after Experimental Subarachnoid Hemorrhage in Rats. With therapy (70 mg/kg Allicin, rather than 30 mg/kg) 30 min post SAH, groups showed better neurological scores in 24 h. Significant differences could be found in body weight ratio between the SAH + vehicle groups and SAH + Allicin groups. Treatment with 70 mg/kg, not 30 mg/kg, Allicin significantly reduced brain edema and EB extravasation in 24 h after SAH. Assessments in 24 h after SAH showed that treatment with 70 mg/kg Allicin in 30 min after SAH significantly restrained the expression of cleaved caspase-3, mitigated the severity of neuronal degeneration, decreased the proportion of apoptotic neurons and the elevated MDA levels, and increased the suppressed GSH and SOD levels. We demonstrated for the first time that Allicin extenuated brain edema and blood-brain barrier dysfunction, improved neurological outcomes by the suppression of apoptosis and oxidative stress damageafter SAH in experimental models, which may shade new light on the treatments of SAH.
