This study was designed to investigate the effect of Korean Red ginseng(Panax ginseng C.A. Meyer) extracts on antioxidative activities in Sprague-Dawley rats. This study also evaluated the synergistic effect of Korean red ginseng(RG) extracts with Saururus chinensis(Lour.) Baill(SC). and Rubus coreanus Miq.(RC) extracts. Experimental groups were divided into supplementation type(RG extracts, RG with SC and RC extracts) and amounts of extracts. Rats were received drinking water with or without RG, RC and SC extracts for eight weeks. In the antioxidant enzyme activities of liver cytosol, superoxide dismutase, catalase and glutathione peroxidase activities were significantly increased in RG groups and RG with SC and RC groups compared to control group. The antioxidative activities were increased in proportion to supplementation period and amounts of extracts. These results suggest that RG, RC and SC extracts have an beneficial effect to enhance the cellular antioxidant activities in rats.

The purpose of this study is to investigate the antibacterial efficacy of cotton and silk/rayon fabrics dyed with Saururus chinensis extract against antibiotic-resistant strains. The concentration of the concentrated dye in the Saururus chinensis extracts was 1.1% (o.w.f), and the liquor ratio was 1:10 at 30-70℃. The mordanting method was a post mordanting method. The concentration of Al2(SO4)3, CuSO4 5H2O and FeSO4 and7H2O mordant was 5% (o.w.f), and the liquor ratio was 1:40. In order to assess the antimicrobial activity of naturally dyed fabrics, Methicillin-resistant Staphylococcus aureus (MRSA) ATCC 33591, was used by incubating it in Brain Heart Infusion Agar (BHA) including Oxacillin (2㎍/ml) and Fungizone (2.5㎍/ml) and Brain Heart Infusion broth (BHI; Detroit, MI, USA.) The investigation of the reduction of the rate of antibiotic-resistant strains to dyed cotton fabrics and silk/rayon fabrics revealed that Cu mordanting fabric has the highest antimicrobial effects, with the rate of 99.7%, and Fe mordanting fabric has the lowest, with 77.7%. Non-mordant cotton fabrics also show a high reduction rate of strains (94.6%). In the case of dyed silk/rayon fabrics, it indicates a high reduction in the rate of strains in all fabrics with non-mordant treatment (94.2%), Al mordanting (99.6%), and Cu and Fe mordanting(99.9%).

We investigated the effect of Saururus chinensis (Lour.) Baill (SCB) on allergy in mice. We conformed compound 48/80-induced mesenteric mast cell degranulation, active systemic anaphylatic shock and histamine release. Also observed acetic acid-induced vascular permeability and anti-dinitrophenyl (DNP) IgE-mediated passive cutaneous anaphylaxis. SCB inhibited mesenteric mast cell degranulation and active systemic anaphylatic shock induced by compound 48/80 dose-dependently. When SCB was pretreated by intra-peritoneal injection, the plasma histamine levels were reduced. SCB also significantly inhibited acetic acid-induced vascular permeability and anti-DNP IgE-mediated passive cutaneous anaphylaxis. In addition, SCB reduced IL-10 mRNA expression of the lung on ovalbumin-induced allergy. These results indicate that SCB inhibits allergy.

Five liglans, sauchinone (1), di-0-methyltetrahydrofuriguaiacin B (2), manassantin A (3), manassantin B (4) and saucerneol B (5), have been isolated from the MeOH extract of Saururus chinesis roots. The evaluation for protective effect of compounds 1-5 against tacrine-induced cytotoxicity in human liver-derived Hep G2 cells was conducted. Compounds 1,2, and 5 showed significant protective effects with the EC$_{50}$ values of74.2${\pm}$0.9, 111.3${\pm}$0.8,64.3${\pm}$0.8 ${\mu}$M, respectively. Silybin, one of the well-known hepatoprotective agents, used as a positive control, and also showed protective effect with an EC$_{50}$ value of 86.2${\pm}$0.5 ${\mu}$M.

Saururus chinensis (Lour.) Baill. (Saururaceae) has been used as a traditional medicine for the treatment of dysuria, leukorrhea, eczema, jaundice and ascites in Korea, China and Japan. Ethanol extract of S. chinensis was successively partitioned as methylene chloride, ethyl acetate, n-butanol and $H_2O$ soluble fractions. Among those fractions the ethyl acetate soluble fraction showed the most potent DPPH radical scavenging and superoxide quenching activities. To verify antioxidant activities of ethyl acetate fraction, we checked the activities of superoxide dismutase (SOD) and catalase, and intracellular ROS level and oxidative stress tolerance in Caenorhabditis elegans. Furthermore, to see if increased stress tolerance of worms by treating of ethyl acetate fraction was due to regulation of stress-response gene, we quantified SOD-3 expression using transgenic strain. Consequently, ethyl acetate fraction elevated SOD and catalase activities of C. elegans, and reduced intracellular ROS accumulation in a dose-dependent manner. Moreover, ethyl acetate fraction-treated CF1553 worms exhibited significantly higher SOD-3::GFP intensity.

Saururus chinensis Baill has been used in Korean folk medicine for the treatment of various diseases such as edema, Jaundice, and furuncle. The components of this plant were extracted into four fraction. Among the four fraction, hexane and ethyl acetate fraction were highly toxic to 3T3 mouse embryo fibroblast and Raw 264.7 mouse macrophage, but n-butanol and residue fraction did not show any toxic effect to those cell lines. n-Butanol and residue fraction exhibited antioxidant effects on hydro-gen peroxide, hydroxyl radical, and superoxide anion directly in vitro and in the 3T3 fibroblasts. All the four fractions inhibited lipid peroxidation measured by thiobarbituric acid reactive substances (TBARS) formation. In addition, n-butanol and residue fraction showed inhibitory effects on lipopolysaccharide (LPS)-induced nitric oxide production, and also down-regulated inducible nitric oxide synthase (iNOS) mRNA transcription 6 h after LPS stimulation in Raw 204.7 cells. Only n-butanol fraction, which mainly consists of flavonoids, inhibited NF-kB activation by decreasing IkBa degradation 90 min after LPS stimulation. horn the results, it is suggested that this plant could be a good candidate material for drug development based on its antioxidant and/or anti-inflammatory constituents.

The contents of quercetin glyciside in Saururus chinensis Baill was higher in the 2nd year, 1st year and 3rd year in leaves, and in the 1st year, 3rd year and 2nd year in stems in that orders. Content of lignans in the rhizome was not significantly different cultivated years. The total phenolics, quercetin glycoside and EDA of plant parts were higher in order of flower, leaf and chopping sample. The total phenolics and EDA of stem were much lower than parts and quercetin glycoside was not detected.

This study was conducted to investigate the antitoxic component in ethanol extract of Saururus chinesis (S. chinesis). The results were as follows: Generally, detoxication effects by s. chinesis extract increased in proportion to the extract concentration. non 8 $\mu\textrm{g}$/g dosage of S. chinesis extract was administered, it showed the highest antitoxic effects in metallothionein induction. After the extract treatment, body weights generally increased In proportion to the extract concentrations. from the above results, S. chinesis extract Increased Metallothionein concentration and decreased the toxicity of cadmium In rats. In vitro the antitoxic activity of ethanol extract of S. chinesis on NIH3T3 fibroblasts was evaluated by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide) and SRB (sulforhodamine B protein) assays. The light microscopic study was carried out to observe morphological changes of the treeated cells. $10^{-2}$mg/ml Concentrations of S. chinesis extract was shown significant antitoxic activity. The number of NIH 3T3 fibroblasts were increased and tend to regenerate. These result suggest that S. chinesis extract retains a potential antitoxic activity.

Objective We investigated the effect of Saururus chinensis (Lour.) Baill. aquacupuncture (SCB) on anaphylaxis in mice. Methods : We conformed compound 48/80-induced mesenteric mast cell degranulation, active systemic anaphylatic shock and histamine release. Also observed acetic acid-induced vascular permeability and anti-dinitrophenyl (DNP) IgE-mediated passive cutaneous anaphylaxis. Results : SCB inhibited mesenteric mast cell degranulation and active systemic anaphylatic shock induced by compound 48/80 dose-dependently. When SCB was pretreated by intra-peritoneal injection, the serum histamine levels were reduced. SCB also significantly inhibited acetic acid-induced vascular permeability. In addition, SCB showed a significant inhibitory effect on anti-dinitrophenyl (DNP) IgE-mediated passive cutaneous anaphylaxis. Conclusion : These results indicated that SCB inhibits anaphylatic reaction.
