Objectives: The object of this study was to observe the in vitro antibacterial effects of five single(Pulsatillae Radix, Patrinae Radix, Sanguisorbae Radix, Sophorae Flos, and Sophorae Radix) aqueous herbal extracts, traditionally used for treating various gynecological diseases including mastitis in Korea, against Staphylococcus aureus. Methods: Antibacterial activities against Staphylococcus aureus of aqueous extracts of Pulsatillae Radix, PatrinaeRadix, Sanguisorbae Radix, Sophorae Flos, and Sophorae Radix were detected using standard agar microdilution methods. In addition, the effects on the bacterial growth curve were also monitored at Minimal Incubation Concentration(MIC) and $MIC{\times}2$ levels. The effects on the intracellular killing and bacterial invasion of individual test materials were also observed using murine macrophage(Raw 264.7) and human mammary gland carcinoma cell(MCF-7). Results: MIC of aqueous extracts of Pulsatillae Radix, Patrinae Radix, Sanguisorbae Radix, Sophorae Flos, and Sophorae Radix against Staphylococcus aureus were detected as $0.215{\pm}0.107$ mg/ml, $0.273{\pm}0.107$ mg/ml, $0.469{\pm}0.297$ mg/ml, $11.850{\pm}8.406$ mg/ml, and $0.664{\pm}0.546$ mg/ml, respectively. MIC of Ciprofloxacin was detected as $0.469{\pm}0.297{\mu}g/ml$ at same conditions. In addition, all five single aqueous herbal extracts were also showed marked dosage-dependent inhibition of bacterial growth. The effects of intracellular killing with Raw 264.7 and inhibition of bacterial invasion with MCF-7 cells were detected, in the order of Sophorae Flos, Pulsatillae Radix, Patrinae Radix, Sanguisorbae Radix and Sophorae Radix aqueous extracts in the present study. Conclusions: The results obtained in this study suggest that all five single aqueous herbal extracts showed antibacterial effects against Staphylococcus aureus and they also showed dosage-dependent inhibitory effects on the bacterial growth. They showed the significant intracellular killing and inhibition of bacterial invasion effects. It means, all five single aqueous herbal extracts may show potent anti-infectious effects against Staphylococcus aureus for mastitis.

To investigate the antiinflammatory and analgesic effects of Sophorae radix extracts administered to the arthritic rat model, immunohistochemical stains for CGRP in the L4, L5 and L6 spinal cord and ganglia were done, and paw swelling thickness were measured. Complete Freund,s Adjuvant(CFA) were injected to subcutaneous tissue of left foot paw of rats to induce arthritis. Sophorae radix extracts was administered immediately after CFA injection for 10 days. The spinal cord and ganglia were frozen sectioned(30㎛). These sections were stained by CGRP immunohistochemical staining method, and observed with light microscope. The results were as follows : 1. The change of paw swelling thickness of experimental group decreased from 4 day to 10day after CFA injection compared to control group. 2. The change of differential leukocytes counts of experimental group increased the ratio of lymphocytes. and decreased the ratio of neutrophils compared to control group. 3. The change of CGRP immunoreactive nerve fiber of dorsal horn of experimental group was dense stained compared to control group. 4. The number of CGRP immunoreactive neurons of L4 and L5 spinal cord of experimental group was less than in those control group. These results suggested that Sophorae radix extracts reduces the number of CGRP immunoreactive neurons and nerve fibers of spinal cord and ganglia, and decrease paw swelling thickness in arthritic rat model, which may be closely related to analgesic and antiinflammatory effects of Sophorae radix.

Objectives : Sophorae Radix (SR), the dried root of Sophorae Flavescens Aiton, has been used to treat atherosclerosis, arrhythma and skin diseases including scabies and eczema. The present study was examined to evaluate antimicrobial activities of SR extracts against oral microorganism. Methods : Antimicrobial properties of SR extracts were determined by agar diffusion method and minimum inhibitory concentration (MIC) against Streptococcus mutans, Streptococcus sobrinus and Actinomyces viscosus. Analysis of kurarinone from SR extracts was conducted using UPLC (Ultra Performance Liquid Chromatography). Results : The ethanolic extracts of SR showed stronger antimicrobial effect than methanolic extracts, while the aqueous extracts of SR had no activity. In addition, the higher content of kurarinone was found in ethanolic extracts than methanolic extracts. The purified kurarinone from ethanolic extracts showed potent antimicrobial activity with the MIC value of $3.9{\sim}7.8{\mu}g/m{\ell}$. Conclusion : An ethanolic extract of SR showed antimicrobial properties against several oral microorganisms, and kuranrinone contributed to antimicrobial action of SR. Thus, ethanolic extracts of SR or purified kurarinone should be beneficial for the preparation of the useful agent for treating oral disease including anticaries.

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 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.

To investigate the protective effect of Sophorae Radix (SR) on the damage by pulmonary vascular endothelial cells by xanthine oxidase (XO)/hypoxanthine (HX)-induced oxygen tree radical, Neutral Red (NR) and c-fos immunopositive cell assay were used. The results were obtained as follows ; The viability of vascular endothelial cells treated with XO/HX was decreased. And c-fos immunopositive cells represented a maximal increase in group treated with XO/HX for 2 hour in pulmonary vasvular endothelial cells. But pretreated groups with SR extracts were not inhibited the increase of c-fos immunopositive cells by XO/HX in a dose-dependent manner. These results show that XO/HX elicits toxic effects in cultured pulmonary vascular endothelial cells, and suggest that SR extract is very effective in the prevention of XO/HX-induced increase of c-fos immunopositive cells.
