The purpose of this study was to investigate the anti-cancer effects of Sophorae Radix and the effects of 5-Fluorouracil (5-FU) in human colorectal adenocarcinoma cells (HT-29). We used human colorectal adenocarcinoma cell line, HT-29 cells. We examined cell death by MTT assay and caspase 3 assay with Sophorae Radix. To examine the inhibitory effects of Sophorae Radix, cell cycle (sub G1) analysis was done the HT-29 cells after three days with Sophorae Radix. The reversibility of Sophorae Radix was examined on one day to five days treatment with $150{\mu}g$ Sophorae Radix. Sophorae Radix inhibited the growth of HT-29 cells in a dose-dependent fashion. Also we showed that Sophorae Radix induced apoptosis in HT-29 cells by MTT assay, caspase 3 assay and sub-G1 analysis. Sophorae Radix combined with 5-FU markedly inhibited the growth of HT-29 cells compared to Sophorae Radix or 5-FU alone. After 3 days treatment of HT-29 cells with Sophorae Radix, the fraction of cells in sub-G1 phase was much higher than that of the control group. Our findings provide insight into unraveling the effects of Sophorae Radix in human colorectal adenocarcinoma cells and developing therapeutic agents against colorectal cancer.

Objectives : Sophora flavescens (SF) is widely used in traditional herbal medicine in Korea and is well recognized for its anti-inflammatory effect. However, its effect on Tumornecrosis factor alpha (Tnf) production in BV2 microglial cell is not yet known. Methods : We investigated the effect of SF on the production and expression of Tnf, a well known inflammatory mediator, in lipopolysaccaride (LPS)-activated BV2 microglial cells. Results : The LPS-induced Tnf production was markedly reduced by treatment with SF (50 ${\mu}g/ml$). In reverse transcription polymerase chain reaction (RT-PCR) analysis, SF suppressed the LPS activated expression of Tnf mRNA. In addition, Western blot analysis confirmed that SF suppressed the expression of Tnf. Sophora flavescens also inhibited the LPS-induced phosphylation of extracellular signal-regulated kinases (ERK), which mediate the Tnfproduction signaling pathway whereas LPS-induced phosphylation of p38 mitogen activated protein kinase (p38 MAPK), and c-Jun NH2-terminal kinases (JNK) was not inhibited by SF, which implies that SF suppresses LPS-induced Tnf production via the ERK mediated pathway. Conclusion : Taken together, these findings indicated that SF inhibits LPS-induce Tnf production, and that this inhibitory effect is mediated via the ERK pathway.

Objectives : This study aims at examining the effect of the fermentative extract of root of Sophorae Radix on the immuno-modulating activity. Methods : Cell viabilities were measured by MTT assay. Effect of SFS on nitric oxide(NO), hydrogen peroxide production from RAW 264.7 cells was accessed by Griess reagent assay. Effect of SFS on productions of inflammatory cytokines such as TNF-${\alpha}$, IL-6 in LPS-induced RAW 264.7 cells was accessed by a multiplex bead array assay based on xMAP technology. Results : The results of the experiment are as follows. 1. As a result of carrying out MTT assay to check the cellular toxicity of the fermentative extract of Sophorae Radix. There was not any excessive toxicity to the macrophage when the fermentative extract of root of Sophorae Radix was treated in different concentrations. 2. The fermentative extract of Sophorae Radix increased the generation of hydrogen peroxide in the macrophage and significantly restored the suppression of the generation of the hydrogen peroxide in the macrophage induced by LPS. 3. The fermentative extract of Sophorae Radix reduced the generation of NO in the macrophage and significantly suppressed the increase of the generation of NO in the macrophage induced by LPS. 4. The fermentative extract of Sophorae Radix significantly decreased the amount of TNF-${\alpha}$ generated in the macrophage induced by LPS when it was $25{\mu}g/mL$ or higher. Conclusion : These results suggest that SFS has anti-inflammatory moiety related with its inhibition of NO, hydrogen peroxide, TNF-${\alpha}$, IL-6, in macrophage led by LPS.

Streamflow responses to irrigation reservoirs and groundwater withdrawals were simulated using the integrated surface-water and groundwater model, SWAT-MODFLOW for the upstream watershed of the Gongdo station located in the Anseong stream. The simulated results indicated that the irrigation water supply from the Gosam and the Geumkwang reservoirs has caused the decrease of 31.2%, 82.5% in drought flows below the reservoirs, respectively, against the natural flow condition. While, at the outlet of the study watershed, the effects of the irrigation reservoirs were insignificant due to the delayed return flows with the decrease of 5.7% in drought flow. Both of the irrigation reservoirs and groundwater withdrawals have reduced the drought flows by 19.2% at the Gongdo station.

The aim of study was to elucidate dyeability and antimicrobial and antifungal activity of silk fabrics dyed with Sophora Radix extracts according to different mordants. Dyes were extracted from Sophora Radix using ethanol. Then, silk fabrics were dyed with extracts two times by post-mordanting method in which the extract was 60%(owf), the mordant was 3%(owf), L.R was 1:20, the temperature was $60~60^\circ{C}$, the time of dyeing was 60min., and the time of mordanting was 60min. The dyeability was evaluated by surface color, K/S values and durability of dye. The skin microorganisms used in this study was S. sureus, B. subtilis, S. epidermidis, P. acnes, P. aeruginosa, E coli, A. niger, C. albicans and T. mentatrophytes. The results are as follows; 1. When mordants were added, K/S value of silk dyed was not improved much and surface color was 2.2Y to 8.8Y in H(hue) value which indicated greenish yellow to raddish yellow 2. The color fastness tests to light, perspiration, dry-cleaning, rubbing, and stain fabric washing show 4~5th degree which were valuated excellent. The color fastness to fade washing was improved to 3~4th degree by addition of $K_2CrO_7$ mordants. 3. Antibacterial activity of silk dyed using no-mordant as well as mordants was excellent on S. aureus, B. subtilis, S.epidermidis and P.acnes, but showed poor antibacterial activities on P.aeruginosa and E.coli such as gram negative baterials 4. Antifungal activity of silk dyed with ethanol extracts was good on A.niger, C.candida and T.mentagrophytes. Especially, on T. mentagrophytes there was no growth of fungus during 72 gous in silk dyed mordanting with $SnCl_2\cdot{2H}_2O$.

Background : Radix Sophora Flavescentis (SF) is used for the treatment of diabetes mellitus in Traditional Korean Medicine. However, little is known about the effects of Radix Sophora Flavescentis extract (SFE) on the hypoglycemic mechanism. Objective : We performed a series of experiments to verify the effects of SFE on the proliferation of RIN-m5F, the secretion and synthetic processes of insulin with glucose stimulation and inhibition of $\alpha$-glucosidase. Methods : Various amounts of SFE were added to the RIN-m5F cell culture to identify the effects on the cell proliferation, total amounts of insulin secretion, and related gene expression at the molecular level. Also to identify the inhibitory effect on the $\alpha$-glucosidase activities, ${\rho}NPG$ assay was done with various SFE concentrations followed by comparison with control. Results : SFE did not show considerable effects on RIN-m5F cells proliferation, insulin secretion or insulin mRNA expression, whichever phenomena did not depend on the glucose concentration. However, SFE significantly inhibited $\alpha$-glucosidase activity in a dose dependent manner compared to control. Conclusions : This study showed that SFE has potent $\alpha$-glucosidase inhibitory activity. Thus, SF may by used for the improvement of overall glycemic control. Further mechanism studies on the lipid toxicity and oxidation stress of SF seem to be necessary.

Sophorae Radix, the dried roots of Sophora flavescens Aiton (Leguminosae), has been used in oriental traditional medicine for treatment of skin and mucosal ulcers, sores, gastrointestinal hemorrhage, diarrhea, inflammation and arrhythmia. Present study was carried out for the gastroprotective effect of trifolirhizin from Sophora flavescens. This reports were evaluated antibacterial activity against Helicobacter pylori and HCl ethanol-induced gastric lesion in rats and showed the significant effectiveness. In pylorus ligated rats, the treatments of trifolirhizin showed decrease in the volume of gastric secretion and acid output. Also we evaluated the antibacterial activity against H. pylori treated with methanol extract and trifolirhizin from Sophora flavescens had a equivalent antibacterial activity with ampicillin against H. pylori at the dose of $100{\mu}g/mL$. It may be regarded that the antigastritic effects and antibacterial activity of trifolirhizin from Sophora flavescens are originated from reduction of total acid output identified by gastric secretion reduce, free radical scavenging effects and the antibacterial activity against H. pylori.
