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.

BACKGROUND: Botanical insecticides, especially Azadirachta Indica extract (AIE) and Sophorae radix extract (SRE) are widely used in Agriculture field. In our previous studies on genotoxicity test of AIE and SRE samples, a suspicious clastogenic properties was shown. Herein, we investigated the DNA damage effect of these botanical insecticide samples through the in vitro comet assay. METHODS AND RESULTS: Chinese hamster lung (CHL) fibroblast cell line was used, and methyl methanesulphonate was as positive control. Respective two samples of AIE and SRE were evaluated using Single Cell Gel Electrophoresis (Comet) assay and measured as the Olive tail moment (OTM). Results from this study indicated that all tested AIE and SRE samples did not show DNA damage in comet assay using CHL cells, compared with control. CONCLUSION: AIE and SRE samples used in this study were not cause genetic toxicity and are suitable for use as organic materials.

Backgrounds and Objectives: Asthma is considered to be an inflammatory disease characterized by airway hyperresponsiveness and Pulmonary eosinophilia. And it is known the structure and function of IL-5, its receptor and the mechnism IL-5 triggered eosinophil accumulation and inflammaion of the airways. At this point of view, we assume which oriental materia medics can the splenocyte inhibit from secreting the IL-S in vitro. Material and Methosds: We used the splenocyte of mouse 8 weeks after its birth, and then cnltivated those into the 2 experimental groups and control group for 48 hours. The culture medium of experimental groups were made of $1{\mu}g/ml,\;10{\mu}g/ml$, oriental materia medics, representative. And the culture media of control group was given no oriental materia medica. Then, we assayed the quantity of cytokine-expression by the Sandwich ELISA. The quantifies of cytokine-expression of the experimental groups were compared with that of the control group which was standardized These method were used for the all of oriental materia medica treated. Results: In this study, we demonstrated that 12 oriental materia medica that inhibit the splenocyte from secreting the IL-5 in both $1{\mu}g/ml,\;and\;10{\mu}g/ml$ culture media. Those were Equiseti Herbs, Sophorae Subprostratae Radix, Moutan Radicis Cortex. Trichosanthis Radix, Buddleiae Flos. Cyperi Rhizoma. Benincasae Semen, Armeniacae Semen. Zedoariae Rhizoma, Astragali Semen, Dolichoris Semen. Lilii Bulbus, Asparagi Radix, Atractylodes Rhizoma White, Polygonati Officinallis Rhizoma. Conculusions: These findinga indicate that some oriental materia medica, specially Antipyretics, Herbs for Resolving Phlegm, Relieving Cough and Calming Wheezing and Herbs for Tonifring and Invigorating effects inhibit the splenocyte from secreting the IL-5. And further study experimented in vivo is needed for treating IL-5-driven inflammatory disease including asthma.

Sophorae radix extract (SRE) has been registered as an environment-friendly organic material that is widely used in the cultivation of crops in Korea. Matrine, the active ingredient in SRE, was reported as a toxic substance in the nervous system in mice. However, no information is available on its toxic effects in other organisms. Therefore, antimutagenicity and two kinds of genotoxicity tests (bacterial reverse mutation and chromosome aberration test) of two samples of SRE were investigated in this study. Antimutagenicity test was experimented by using bacterial reverse mutation test. In the reverse mutation test, Salmonella Typhimurim TA98, TA1535 and TA1537 were used to evaluate the mutagenic potential of SRE. Bacterial reverse mutation test was also performed on positive and negative control groups in the presence of the metabolic activation system (with S-9 mix) and metabolic non-activation system (without S-9 mix). In the chromosome aberration test, Chinese hamster lung cells were exposed to SRE for 6 or 24 hours without S-9 mix, or for 6 hours with S-9 mix. Negative and positive control groups were experimented for chromosome aberration test. As a result, the number of mutated colonies induced by 4-NQO were reduced by SRE treatment in all strains, indicating that SRE may have antimutagenic effects. Reverse mutation was not shown at all concentrations of SRE, regardless of application of the metabolic activation system. In the chromosomal aberration test, one of the SRE sample gave a suspicious positive result at 250 ${\mu}g/ml$ in the presence of S-9 mix. For the more adequate evaluation of the genotoxic potential of SRE samples, other in vivo genotoxicity study is needed.

Objective : Kurarinone is one of the flavonoids isolated from Sophorae Radix with various biological activities including anti-microbial effect. In this study, we investigated the effects of Kurarinone on tert-butyl hydroperoxide (tBHP)-induced oxidative stress finally leading to apoptosis in human hepatoma cell line HepG2. Methods : To determine the effects on cell viability, the cells were exposed to tBHP ($100{\mu}mol/l$) after pretreatment with kurarinone (0.5 and $1{\mu}g/ml$). Cell viability was measured by MTT assay. To reveal the possible mechanism of cytoprotectivity of kurarinone, levels of reactive oxygen species, intracellular glutathione, mitochondrial membrane potential, and expression of caspase were examined. Results : tBHP-induced cell death was due to oxidative stress and the resulting apoptosis. Kurarinone dose-dependently protected cells from apoptosis when determined by MTT and TUNEL assay. Consistent with this observation, decreased expression of pro-caspase 3/9 protein by tBHP was restored by kurarinone. Kurarinone also showed anti-oxidative effects by inhibiting generation of ROS and depletion of GSH in tBHP-stimulated HepG2 cells. In addition, kurarinone significantly recovered disruption of mitochondrial membrane potential (MMP) as a start sign of hepatic apoptosis induced by oxidative stress. Conclusion : From these results, it was concluded that kurarinone protected tBHP-induced hepatotoxicity with anti-oxidative and anti-apoptotic activities. Our results suggest that kurarinone might be beneficial to hepatic disorders caused by oxidative stress.

This study was conducted to determine if YJ-1, a novel herbal complex from a mixture of six oriental herbs (Hydnocarpi Semen, Sesami Semen, Dictamni Radicis Cortex, Momordicae Semen, Xanthii Fructus, and Sophorae Radix), has therapeutic properties for the treatment of atopic dermatitis (AD). Using AD like symptom-induced NC/Nga mice by 1-chloro 2,4-dinitrobenzene (DNCB), the effectiveness of YJ-1 on AD was evaluated. Elidel cream$^{(R)}$ (1% pimecrolimus) was used as a control. Dermal application of YJ-1 reduced major clinical signs of AD such as erythema, pruritus, lichenification, edema/escoriations, and dryness. Interestingly, YJ-1 more improved AD-related symptoms including decrease of spleen weight, IL-4, and IgE level in the serum as well as reduction of scratching counts and clinical skin severity in the NC/Nga AD mouse model. Especially, treatment of YJ-1 at 20% in NC/Nga mice more effected than Elidel cream. These results suggest that the ointment of YJ-1 may enhance the process of AD healing by alleviating allergic reaction and has potential for therapeutic reagent for the treatment of AD.
