Abstract

Objectives: The purpose of this investigation is to evaluate the effects of Woohwangcheongsim-won and to study the mechanism for neuronal death protection in OGD (oxygen-glucose deprivation) model with embryonic day 20 (E20) cortical cells of a rat (Sprague Dawley). Methods: E20 cortical cells were dissociated in neurobasal media and grown for 14 days in vitro (DIV). On 14 DIV, Woohwangcheongsim-won was added to the culture media for 72 hrs. On 17 DIV, cells were given an oxygen-glucose deprivation shock (2hrs and 4hrs) and further incubated in normoxia for another three days. On 20 DIV, Woohwangcheongsim-won's effects for neuronal death protection were evaluated by LDH assay and the mechanisms were studied by Bcl-2, Bak, Bax, caspase family. Results & Conclusions: 1. This study indicates that Woohwangcheongsim-won's effects for neuronal death protection in OGD model is confirmed by LDH assay in culture method of embryonic day 20(E20) cortical neuroblasts. 2. Woohwangcheongsim-won's mechanisms for neuronal death protection in OGD model are to restrain inflow of cytochrome c into cellularity caused by Bcl-2 increase (2hrs and 4hrs), to reduce the caspase cascade initiator caspase-8 (4hrs).
