Objectives : This experiment was designed to investigate the effect of the BSGE hot water extract on serotonin biosynthesis of depression model. Methods : The cytotoxicity of the BSGE hot water extract was analyzed by MTT assay on P815 cell. The antioxidant activity was measured by DPPH free radical-scavenging activity and SOD activity on P815 cell. The quantity of 5-HT and expression of TPH-1, AAADC and MAOa mRNA was measured by of HPLC profle Analysis on P815 cell. Results : 1. The BSGE hot water extract increased DPPH free radical-scavenging activity and SOD activity on P815 cell. 2. The BSGE hot water extract increased significantly the quantity of 5-HT. 3. The BSGE hot water extract increased the expression of TPH-1 mRNA. Conclusions : This experiment shows that the BSGE hot water extract might be effective for the prevention and treatment of depression. Investigation into the clinical use of the BSGE hot water extract for depression is suggested for future research.

Objectives : This experiment was designed to investigate the effect of Gamisoyo-san(Jiaweixiaoyaosan, SYS) on serotonin activity of P815 Mast Cell. Methods : The effects of SYS on activation of TPH-1 mRNA and AAADC mRNA in P815 mast cell were investigated. The effect of SYS on content of serotonin in P815 mast cell was investigated. The effects of SYS on activation of DPPH and SOD in P815 mast cell were investigated. Results : 1. The SYS increased the activation of SOD and DPPH in P815 mast cell. 2. The SYS decreased the manifestation TPH-1 mRNA in P815 mast cell. 3. The SYS decreased the manifestation AAADC mRNA in P815 mast cell. Conclusions : This experiment shows that Gamisoyo-san might not be effective for treating depression in terms of biogenic amine theory. However, Gamisoyo-san showed significant anti-oxidative effect and it can not yet be ruled out for treating depression. Therefore, pathogenesis of depression and clinical research of Gamisoyo-san is suggested for future research.

Objectives: This study was perfomed to investigate the antioxidant activity and serotonin activity of Gami-guibi-tang on P815 Mast Cell. Methods: The effects of Gami-guibi-tang on activation of TPH-1 mRNA and AAADC mRNA in P815 mast cell were investigated. The effect of Gami-guibi-tang on content of serotonin in P815 mast cell was investigated. The effects of Gami-guibi-tang on activation of DPPH radical scavenging and SOD in P815 mast cell were investigated. Results: 1. The Gami-guibi-tang increased SOD activity and DPPH radical scavenging activity. 2. The Gami-guibi-tang increased the intracellular concentration of serotoninin 60 ${\mu}g/ml$, 80 ${\mu}g/ml$ experiment group. 3. The Gami-guibi-tang increased menaingful the manifestation TPH mRNA. 4. The manifestation of AAADC and MAO mRNA have not made menaingful changes on Gami-guibi-tang. Conclusions: This experiment shows that Gami-guibi-tang had significant anti-oxidative effect. And Gami-guibi-tang increased the intracellular concentration of serotonin. Therefore, Gami-guibi-tang can be used by the medication of major depression disorder. But Study on mechanism of increased serotonin and clinical research of Gami-guibi-tang is suggested for future research.
