In Oriental medicine daeseungki-tang is one of the prescription that is used clinically for constipation of paralytics. The objective of the study was to observe the effect of daeseungki-tang on apoptotic neuronal cell death. In the present study, middle cerebral artery occlusion(MCAO) rats were treated with daeseungi-tang for 5 days and the edema percentage of cerebral hemisphere of MCAO rats were investigated primary. Secondary, appearances of Bax, Bcl-2,-factors that is related to apoptotic neuronal cell death - and HSP72 in the brain of MCAO rats were investigated via immunohistochemistry. Daeseungki-tang significantly decreased edema percentage of the cerebral hemisphere of MCAO rats. Daeseungki-tang significantly decreased Bax positive cells, but did not change the apperances of Bcl-2 positive cells in the penumbra of the cerebral cortex and the caudoputamen of MCAO rats. Daeseungki-tang significantly decreased HSP72 positive cells in the penumbra of the cerebral cortex, but not in the caudoputamen of MCAO rats. Based on the present results, it can be suggested that treatment with daeseungki-tang may decrease edema of the cerebral hemisphere and restrain apoptotic neuronal cell death in the penumbra of the cerebral cortex.
