Objectives : To evaluate the neuroprotective effects of modified Bo-Yang-Hwan-O-Tang (BHT), we investigated the neuronal death protection effects to oxidative damages in N2a neuroblastoma cells. Methods : To study the cytotoxic effect of BHT on N2a neuronal cells, the cell viability was determined by MTT assay. To investigate the neuronal death protection of BHT, N2a neuronal cells were induced oxidative damages by H2O2, and assayed the cell viability and DNA fragmentation. We also investigated DPPH free radical scavenging effects of BHT by tube test. Results : In MTT assay, $500{\mu}g/ml$ of BHT was not showed cytotoxic effect on N2a neuronal cells. BHT protected N2a neuronal cells from H2O2-induced cell death in a dose-dependent manner. BHT also protected N2a neuronal cells from H2O2-induced DNA fragmentation. BHT scavenged DPPH free radicals in a dose-dependent manner. Conclusion : These data suggest that BHT may have strong anti-oxidant effects through the free radical scavenging and neuroprotective effects in neuronal cells.
