Objectives : The dried root of Sophora flavescens Aiton have been used to treat patient with skin diseases such as eczema in Eastern countries. S. flavescens can clear away heat and dry dampness and purge sthenic-fire from the liver and gallbladder. Recently, anti-allergic effect of S. flavescens has been reported. However, the effect on skin condition of contact dermatitis still remains unknown. Thus, the purpose of this study is to evaluate the efficacy of S. flavescens on contact dermatitis. Methods : In order to investigate the effects of S. flavescens (methanol extract of S. flavescens, MESR) on skin condition, the contact dermatitis was induced in mice skin by using 1-fluoro-2,4-dinitrofluorobenzene (DNFB). As the effective endpoints, skin thickness, skin weight, histopathological change were checked. In addition, effects on skin lesion, body weight and spleen/body weight ratio were also investigated. Results : Topical application of MESR ($500{\mu}g/day$) lowered skin thickness (P < 0.05) and skin weight (P < 0.05), respectively. MESR-treated group showed diminished spongiosis and immune cell infiltration in skin tissues compared to those of non-treated control group. The inhibition of skin lesions was also observed in MESR-treated group. In addition, MESR did not affect body weight gain and spleen/body weight ratio in contrast with those in dexamethasone-treated group. Conclusion : These data suggest that Sophorae Radix could improve skin lesion of contact dermatitis. This indicates the possibility for Sophorae Radix to be used to patients with skin diseases such as contact dermatitis.

Apoptosis of vascular smooth muscle cells(VSMCs) is essential in atherogenesis, being a factor that modulates its early progression rather than a terminal event in the course of the disease. Various stimuli, including oxide lipoproteins, altered hemodynamic stress and free radical, can induced VSMCs apoptosis in vitro. The protective effects of Sophorae Radix (SR) on apoptotic cell death induced by H₂O₂ were investigated in VSMCs. The viability of VSMCs was markedly decreased by H₂O₂. Sophorae Radix protected the H202-induced apoptotic death of VSMCs, which was characterized as nuclear fragmentation and increase of sub-G0/G1 fraction .. Sophorae Radix decreased the activation of caspase-3 like protease induced by H₂O₂ and recovered control level from H202-induced PARP, Bak, Bcl-XL and mitochondrial membrane potential. These results suggest that Sophorae Radix protected VSMCs apoptotic death induced by H₂O₂ via inactivation of caspase-3 and modulation of mitochondrial function. Also, the expression profile of proteins by using two-dimensional (2-D) gel electrophoresis was screened. Future investigations will need to explore the use of an anti atherosclerotic therapy of Sophorae Radix, which relies on inhibition of the proapoptotic activation of the vascular smooth muscle cells.

Fibroblasts are major cellular components of gingiva and periodontal ligament. They regulate the healing process after surgery or injury. Recently, many natural medicines, whose advantages are less side effects and possibility of long-term use, have been studied for their capacity, their anti-bacterial and anti-inflammatory effects and regenerative potential of periodontal tissues. Sophorae radix have been traditionally used as an anti-bacterial and antiinflammatory drug in oriental medicine. The purpose of present study was to investigate the effects of Sophorae radix extract on cell cycle progression and its molecular mechanism in human gingival fibroblasts. Sophorae radix extracts($100{\mu}g/ml$) notably increased cell proliferation and cell activity in the human gingival fibroblasts as compared to non-supplemented controls. There was an increase in the S phase and a decrease in the G1 phase in $100{\mu}g/ml$ of Sophorae radix extracts group as compared to non-supplemented controls. The level of cyclin E and cdk 2 protein in test group was higher than that of control groups. But that of cyclin D, cdk 4, and cdk 6 was not distinguished from controls. The level of p53 protein in test group was lower than that of controls, whereas that of p21 was not different. The level of pRB protein in test group was higher than that of controls, whereas that of p16 was lower. These results indicate that the increase of cell proliferation by Sophorae radix extracts may be due to the increased expression of cyclin E and cdk 2, and the decreased expression of p53 and p16 in human gingival fibroblasts.

To test the protective effect of Sophorae Radix (SR) on the damage of cardiac endothelial cells by xanthine oxidase (XO)/hypoxanthine (HX)-induced oxygen tree radical, Neutral Red (NR), lactate dyhydrogenase (LDH), and c-fos immunopositive cells assay were used in the presence of SR extract. The results of these experiments were obtained as follows ; Cardiac endothelial cells treated with XO/HX showed the cytotoxicity such as a decrease in viability, and increases in LDH activity and c-fos immunopositive cells. Cardiac endothelial cells pretreated with SR extract protected the increase of LDH activity. Alos, cardiac endothelial cells pretreated with SR extract inhibited the increase of c-fos immunopositive cells. These results show that XO/HX induces toxic effects in cultured cardiac endothelial cells derived from neonatal rat, and suggest that SR extract is very effective in the prevention of XO/HX-induced toxicity.

To test the cytoprotective effect of sophorae radix (SR) against hydrogen peroxide (H₂O₂)-induced cytotoxicity, we investigated the cell viability using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay in the presence of methylene chloride, n-butanol, ethyl acetate and water soluble fraction of SR water extracts in H9c2 cells. These results were obtained as followed; H₂O₂ decreased the cell viability of H9c2 cells in a dose dependent manner. Cells pretreated with SR water extracts were protected the H₂O₂-induced decrease of viability in H9c2 cells. Among organic solvents fractions of SR water extracts, ethyl acetate soluble fractions of SR protected the decrease of viability induced by H₂O₂ in H9c2 cells. These results suggest that ethyl acetate soluble fractions of SR water extracts is effective in the prevention of H₂O₂-induced cytotoxicity.

To test the cytoprotective effect of sophorae radix (SR) against hydrogen peroxide (H₂O₂)-induced cytotoxicity, we investigated the cell viability using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay in the presence of ethyl acetate subfractions of SR water extracts In H9c2 cells. And to clarify the cytoprotective mechanism of SR extracts, we evaluated the cellular glutathione (GSH) contents in the presence of subfraction 1, 2, 3, and 4 of SR ethyl acetate soluble fractions. Among 1 -12 subfractions of SR ethyl acetate soluble fractions, 1, 2, 3 and 4 subfractions have an efficacy inhibiting the cytotoxicity induced by H₂O₂ in H9c2 cells. Also, the protective effects of 1, 2, 3 and 4 subfractions of SR ethyl acetate soluble fractions resulted from the anti-oxidant effects. These results suggest that ethyl acetate soluble fractions of SR water extracts is effective in the prevention of H₂O₂-induced cytotoxicity and 1, 2, 3 and 4 subfraction of ethyl acetate soluble fractions possess the anti-oxidant component.

고삼추출물은 한국에서 유기농업자재로 등록되어 있어 친환경농산물 재배시에 널리 사용되고 있다. 고삼추출물의 유효성분인 matrine은 쥐의 신경계에 독성을 나타낸다고 보고된 바 있으나 다른 안전성 확인 연구는 미비한 상황이다. 따라서 본 연구는 고삼추출물 2종을 이용하여 항돌연변이원성 시험과 유전독성시험 2종(복귀돌연변이 및 염색체이상 시험)을 실시하였다. 항돌연변이원성 시험은 복귀돌연변이 시험방법을 이용하여 실시하였으며, 복귀돌연변이 시험으로는 Salmonella Typhimurium TA98, TA1535와 TA1537을 이용하여, S-9 mix를 사용한 대사활성계 처리군과 PBS를 사용한 대사활성계 미처리군으로 구분하여 진행하였다. 염색체이상 시험은 Chinese hamster lung cells을 이용하여 고삼추출물 시료에 대사활성계 처리군은 6시간 노출시켰고, 대사활성계 미처리군은 각각 6시간과 24시간 노출시켜 시험하였다. 항돌연변이 시험 결과, 4-NQO에 의해 유도된 돌연변이 집락수는 고삼추출물 시료 처리에 의해 감소되어 항돌연변이 효과가 있는 것으로 나타났다. 시험결과, 복귀돌연변이 시험에서는 고삼추출물의 모든 시험 농도군에서 대사활성계의 처리 유무와 관계없이 독성이 나타나지 않았다. 반면, 염색체이상시험 결과 고삼추출물 시료 1종에서 대사활성계 미처리군에서는 250 ${\mu}g/mL$, 대사활성 처리군에서는 500 ${\mu}g/mL$ 의 농도에서 의양성이 나타났고 이 이하의 농도에서는 모두 음성으로 나타났으며, 나머지 시료 1종에서는 모든 처리농도군에서 음성으로 판정되었다. 고삼추출물의 유전독성 가능성을 더 정밀히 평가하기 위해서는 향후 battery system에 포함된 다른 in vivo 유전독성 시험을 추가로 시행하여 유전독성 여부를 최종 확인할 필요가 있다고 판단된다.

Atopic dermatitis is frequently encountered in the Dermatology clinic and the treatments are very various but the effects are not good enough. Especially in case of infants, taking herb med or acupuncture treatments are difficult so we would like to treat the atopic dermatitis using external therapy. We chose the oriental medicine textbooks and the oriental medicine journals that external therapy was used and divided into Yugobub(油膏法), Buchubbub(敷貼法), Sechukbub(洗滌法). The results were as follows: 1. In the frequency of medicine was Coptidis Rhizoma(黃連), Phellodendri Cortex(黃栢), Sophorae Radix(苦蔘), Cnidii Fructus(蛇床子), Allumen(枯礬) etc. 2. The effects of medicine were Chungyul(淸熱), Haedok(解毒), Zosub(燥濕), salchung(殺蟲), Gupung(祛風), Jiyang(止痒) etc.
