초록

Objectives : This Study was performed to assess the antioxidative and neuroprotective effect of Guibi-tang(Guipi-tang) and Guibi-tang gamibang(Guipitang jiaweifang) on PC12 cells.
Methods : The antioxidative effect was investigated through the DPPH radical and ABTS cation scavenging methods and total polyphenol amount of Guibi-tang(Guipitang) and Guibi-tang gamibang(Guipitang jiaweifang). The neuroprotective effect of Guibi-tang(Guipitang) and Guibi-tang gamibang(Guipitang jiaweifang) was assessed using MTT assay in PC12 cells. The scavenging effect of Guibi-tang(Guipitang) and Guibi-tang gamibang(Guipitang jiaweifang) on NO and ROS production induced by 6-OHDA in PC12 cells was evaluated, as well as the attenuating effect of Guibi-tang gamibang(Guipitang jiaweifang) on GSH reduction.
Results : 1. Guibi-tang(Guipitang) and Guibi-tang gamibang(Guipitang jiaweifang) had concentration-dependent scavenging activities of DPPH radical.
2. Guibi-tang(Guipitang) and Guibi-tang gamibang(Guipitang jiaweifang) had concentration-dependent scavenging activities of ABTS cation.
3. Total polyphenol amount of Guibi-tang(Guipitang) and Guibi-tang gamibang(Guipitang jiaweifang) was calculated 79.10±2.20 ㎍/10 ㎎ and 121.03±1.11 ㎍/10 ㎎, respectively.
4. Cell viability of Guibi-tang(Guipitang) was increased in a dose dependent manner. Guibi-tang gamibang(Guipitang jiaweifang) was increased at low concentrations, but decreased at high concentrations.
5. In Guibi-tang(Guipitang), cell viability of PC12 cell treated with 6-OHDA was decreased by pre-treatment, and increased by post- and co- treatment. Cell viability of Guibi-tang gamibang(Guipitang jiaweifang) showed variable effects by pre-treatment, but increased by post- and co- treatment.
6. NO production rate of Guibi-tang(Guipitang) didn't show a significant effect, but that of Guibi-tang gamibang(Guipitang jiaweifang) was decreased in a dose dependent manner.
7. ROS production rate of Guibi-tang(Guipitang) was decreased at some concentrations. In Guibi-tang gamibang(Guipitang jiaweifang), ROS production rate was decreased at high concentrations.
8. Guibi-tang gamibang(Guipitang jiaweifang) protected the 6-OHDA-induced GSH reduction.
Conclusions : These results demonstrate that both Guibi-tang(Guipitang) and GBTGMB have antioxidative and neuroprotective effect, but Guibi-tang gamibang(Guipitang jiaweifang) has more antioxidative and neuroprotective effect than Guibi-tang.
