The water extract of Sophorae radix was tested for its preventive effects against cardiovascular anaphylaxis elicited in experimental animals. H₂O and ethyl acetate fractionation of Sophorae radix water extract improved anaphylactic cardiac dysfunction in passively sensitized isolated guinea hearts: improvement was noted in the maximal contractile force, post-challenge contractile force, post-challenge coronary flow and creatine kinase change elevation. These results suggest that H₂O and ethyl acute fractionation of Sophorae radix water extract possesses anti-anaphylactic effect in cardiovascular system.

The effect of Sacchromyces cerevisiae-Fermented Sophorae Radix water extract (SFS) on production of hydrogen peroxide and nitric oxide (NO) from mouse macrophage Raw 264.7 Cells treated with nicotine (1 mM) was investigated through this study. SFS (0, 25, 50, 100, 200, 400 ug/mL) was simultaneously treated with nicotine (1 mM) during culture of 4, 20, 24, 44, 48, 68, and 72 hr. And the intracellular productions of hydrogen peroxide were measured by dihydrorhodamine 123 (DHR) assay. NO production after 24 hr treatement was measured with Griess reagent assay. SFS restored the production of hydrogen peroxide and NO reduced by nicotine (1 mM) in Raw 264.7 Cells. These results suggests that SFS could be supposed to have the immunological activity concerned with macrophage's oxidative burst including hydrogen peroxide and NO.

Objectives and Methods : Unlike respiratory anaphylaxis responses, mediators responsible for cardiovascular responses are not clearly elucidated. Main characteristics of cardiovascular anaphylaxis include hypotension and cardiac failure (anhythmia and cardiac contraction failure). In this experiment, the fractionations of Sophorae Radix (SR) were tested for its preventive effects against cardiovascular anaphylaxis in pithed rats. Results : Of the SR fractionations, water fractions, at the concentration of 20 and 60mg/kg, was significantly effective on all the cardiovascular changes in pithed rats. Also, of the cardiovascular changes, depressor response was significantly attenuated by the ethyl acetate (EA) fraction, at the concentration of 60mg/kg. Conclusions : These results suggest that water and EA fractions of the SR fractionations possess anti. anaphylactic effects in pithed rats. Additional research is needed to identify active principles for the observed pharmacological effects.

The purpose of this study is to investigate the effect of a mixture of fermented Artemisiae Argi Folium and fermented Sophorae Radix (FAS) on hydrogen peroxide production within mouse macrophage Raw 264.7 with ethanol (EtOH) and nicotine. Artemisiae Argi Folium is known to have the antibacterial, immune-enhancing properties. And Sophorae Radix is also known to have the antibacterial, anti-inflammatory, anti-allergic properties. EtOH and nicotine are the ones of toxicants which could impair immunocytes like macrophage. EtOH and nicotine reduce the intracellular production of hydrogen peroxide ($H_2O_2$) of Raw 264.7. FAS increased the production of hydrogen peroxide reduced by EtOH and nicotine within Raw 264.7. These results indicate that FAS could restore the immuno-activity of macrophage impaired by EtOH and nicotine.

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.

In order to elucidate toxic the mechanism of myocardial damage and the protective effect of herbal extract, Sophorae Radix(SR) against myocardiotoxicity, the cytotoxic effect of adriamycin and cardioprotective effect of SR were examined by MTT assay, LDH activity, heart beat rate and light microscopy after cultured myocardial cells derived from neonatal mouse were treated with various concentrations of adriamycin, an inducer of myocardiotoxicity. Adriamycin induced a decrease of cell viability, an increase in the amount of lactate dehydrogenase(LDH), and a decrease in the heart beat rate and a decrease in the number of cells, when administered to cultures myocardial cells in a dose-dependent manner. In cardioprotective effect of SR. SR showed the decrease of amount of LDH, and an increase of heart beating rate and cells in number on cultured myocardial cells damaged by adriamycin. From the above results, it is suggested that adriamycin shows toxic effect in cultured myocardial cells derived from a neonatal mouse, and herbal extract such as SR is very effective in the prevention of adriamycin-induced cardiotoxicity.

Sophorae Radix (SFR) is known as a therapeutic drug that has been used in Oriental traditional medicine for the treatment of skin and mucosal ulcers, gastrointestinal hemorrhage, diarrhea, inflammation and arrhythmia. In the present study, we examined the effects of the aqueous extract of SFR on anti-inflammation, anti-allergic and anti-oxidant effect in various cell lines; they include mouse lung fibroblast cells (hFCs), human mast cells (HMC-1), human monocytic cells (THP-1), and RAW 264.7 cells. Treatment with SFR extract at a concentration of 250 ${\mu}g$/ml for 24h showed no significant decrease in the survival rate of the hFCs. SFR decreased the mRNA expression of IL-8, TNF-$\alpha$, and IL-6 in HMC-1 cells. SFR extract treatment significantly inhi-bited the protein expression of IL-6 and, IL-8 induced by mite in THP-1 cells and it also did MCP-1 expression. We examined the alternation of histamine release in HMC-1 cells for investigating anti-allergic effect of SFR. Histamine secretion decreased after the treatment with SFR. In addition, SFR extract treatment at a concentration of 10 ${\mu}g$/ml, 100 ${\mu}g$ /ml, and 200 ${\mu}g$/ml lowered the $\beta$-hexosaminidase to 10.3%, 21.7%, and 50.8%, respectively. IC50 of SFR extract in RBL-2H3 cells was 196.85 ${\mu}g$/ml. Both activity of NF-$\kappa$B promoter in RBL-2H3 cells significantly diminished after the dose-dependent treatment of SFR. Therefore, our results indicate that SFR has anti-inflammatory and it may be useful for treating allergic diseases such as atopic dermatitis.
