Objectives : Samchulgeonbi-tang (shenzhujianpi-tang) has been prescribed as one of traditional herbal medicine for treatment of stomach diseases since ancient time in Korea. Samchulgeonbi-tang extract was fermented by Lactobacillus spp. for improving the effect. However, the toxicity and safety of fermented Samchulgeonbi-tang (FS) extract were not confirmed. Therefore, this study was performed to evaluate the acute toxicity and safety of FS extract. Methods : To evaluate the acute toxicity and safety of FS extract, several doses of FS extract, 0, 500, 1000 and 2000 mg/kg, were orally administered to 20 male and 20 female ICR mice, respectively. After treatment with FS extract, we observed mortality, general toxicity, behavior and change of body weight for the 14 days. After 14 days of oral administration, all mice were sacrificed and hematological parameters were analyzed from blood serum. Results : In present study, the toxic signs such as mortality or abnormal behaviors by FS extract were not observed. There are no significant differences between FS-treated group and control group in body weight, organ weights, and hematological parameters. Conclusions : The remarkable adverse effects by FS extract were not observed in ICR mice. Also, any death was not occurred at all treated FS doses, 500, 1000 and 2000 mg/kg. Therefore, the approximate lethal dose (ALD) of FS extract may be more than 2000 mg/kg.

Samchulgeonbi-tang (SC) is well-known traditional herbal medicine which is composed of fourteen medicine herbs. SC has been used for the treatment of the chronic gastritis, indigestion, gastric ulcers, gastroptosis and diarrhea disease. The variation in the amount of bioactive components of SC and its fermentation SC with ten Lactobacillus strains were investigated via high-performance liquid chromatography coupled with diode array detection (HPLC-DAD). Simultaneous qualitative and quantitative analysis of seven bioactive compounds; paeoniflorin, liquiritin, hesperidin, liquiritigenin, kaempferol, atractylenolide III, magnolol were achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard compounds. In the results, the amount of paeoniflorin and hesperidin were 7.967 mg/g, 7.251 mg/g that were the main compounds in SC. The amounts of liquiritigenin was increased by all ten Lactobacillus strains, except strain 128. Especially, the liquiritigenin amount was highest in SC fermented with strain 145 (0.201 mg/g), which was increased by 158.39% compared to SC (0.081 mg/g). In the fermented SC using strains 344, almost components were increased than non-fermented SC, except paeoniflorin and kaempferol. Thus, these results considered that the strains 145 and 344 are most excellent fermentation strains among the 10 species of fermentation strains.

Objectives : Oxidative stress is an important cause of many diseases including liver injury. Therefore, adequate regulation of oxidative stress plays a pivotal role in maintaining liver function. Until recently, there has been no studies on the hepatoprotective effect of Samchulgeonbi-tang (SCGBT). Therefore, the hepatoprotective effect of SCGBT was investigated in HepG2 cells. In this study, oxidative stress was induced by arachidonic acid (AA) and iron. Methods : To analyze the hepatoprotective effects of SCGBT against oxidative stress induced by AA + iron, the cell viability, apoptosis-related proteins and intracellular ROS, glutathione (GSH), and mitochondrial membrane permeability (MMP) were measured. In addition, nuclear factor erythroid 2-related factor 2 (Nrf2) transcription activation and expressions of Nrf2 target gene were analyzed through immunoblot analysis. Results : SCGBT increased the cell viability from AA + iron - induced cell death and inhibited apoptosis by regulating apoptosis related proteins. SCGBT protected cells by inhibiting ROS production, GSH depletion, and MMP degradation against AA + iron induced oxidative stress. Furthermore, Nrf2 activation was increased by SCGBT, and the Nrf2 target genes were also activated by SCGBT. Conclusions : These results suggest that the SCGBT has a hepatocyte protection effect and antioxidant effect from AA + iron induced oxidative stress.

Objectives: This study was designed to investigate the basis for developing the herbal decoction that may help promote healthy blood vessels in accordance with the basic principles of Korean medicinal materials. Methods: In this study, we investigated the vascular relaxation effects of fifty herbal decoctions on vascular response in isolated thoracic aorta of phenylephrine-preconracted rats. Results: The results of identify the vascular relaxation effect of fifty herbal decoctions provided by Korea Institute of Korean Medicine, twenty-one herbal decoctions showed vascular relaxation effects. Among them, four herbal decoctions, Mahwang-tang (麻黃湯), Samchulgeonbi-tang (參朮健脾湯), Cheonwangbosim-dan (天王補心丹), and Socheonglyong-tang (小靑龍湯), with showed significantly concentration-dependent vasodilation was examined. Vascular relaxation level are $84.02{\pm}4.70$, $79.39{\pm}13.9$, $51.26{\pm}12.56$, and $54.73{\pm}15.8%$, respectively (P<0.05, 0.01, and 0.001). Conclusions: Thus these results provide a basic data for the treatment of the impairment of vascular function and blood pressure in traditional Oriental medicine.
