The purpose of this study was to observe the effects of the feeding physiological activity substance in Saururus chinensis Baill extract on the improvement of the blood glucose, electrolyte (Na, K, CI) concentration and lipid metabolism in the serum of streptozotocin (STZ, 55 mg/kg B.W., I.P. injection)-induced hyperglycemic rats fed the experimental diets for 5 weeks. Concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglyceride (TG) and phospholipid (PL) in serum were significantly higher in the hyperglycemic group (group NSW), STZ (I.P.)+Saururus chinensis Baill leaf 3.5 g% extract group (group NSSL) and STZ (I.P.)+Saururus chinensis Baill root 3.5 g% extract group (group NSSR) than those in the control group (group Normal, basal diet+water). But the concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, TG and PL in serum were remarkably lower in the groups NSSL and NSSR than those in the NSW, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the groups NSSL and NSSR were significantly higher than in the group NSW. Electrolyte and creatinine concentrations in serum were significantly lower in the groups NSSL and NSSR than those in the group NSW. The activities of aminotransferase (AST, ALT), creatine phosphokinase (CPK), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) in serum were remarkably lower in the groups NSSL and NSSR than in the hyperglycemic group NSW. However, no significance was found in the comperative effect of the groups NSSL and NSSR. From the above results, it was suggested that Saururus chinensis Baill was effective in the improvement of the blood glucose, electrolyte, glucide and lipid metabolism in serum of STZ-induced hyperglycemic rats.

Background: This study was performed to evaluate the protective effect of Saururus chinensis ethanol extract (SCE) against styrene toxicity in mouse spermatocyte cells [GC-2spd (ts) cell line]. Methods and Results: Cytotoxicity in mouse spermatocyte cells was measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Generation of reactive oxygen species (ROS) was determined using 2',7'-dichlorodihydrofluorescein diacetate (DCF-DA) assay. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) and western blotting were performed to quantify the mRNA and protein expression levels, resepectiviely, of stress or apoptosis-related genes including p21, p53, heat shock protein 70 (Hsp70), heat shock protein 90 (Hsp90), Bax, Bcl-2, and caspase-3. The results of the MTT assay showed that $50 {\mu}g/m{\ell}$ SCE did not affect cell viability. ROS generation in mouse spermatocyte cells increased by treatment with $100{\mu}M$ styrene, and decreased by co-treatment with SCE. SCE repressed the mRNA expression of stress-related genes, which increased by styrene treatment. In addition, SCE inhibited the apoptosis of mouse spermatocyte cells by ameliorating mRNA and protein levels of apoptotic genes that were altered by styrene treatment. Conclusions: These results suggest that SCE may alleviate styrene toxicity in mouse spermatocyte cells by reducing ROS stress and regulating genes related to styrene toxicity.

In the course of our search for intercellular adhesion molecule-1 (ICAM-1)/leukocyte function-associated antigen-1 (LFA-1) mediated cell adhesion inhibitors from natural sources, new type of cell adhesion inhibitors were isolated from the MeOH extract of Saururus chinensis roots. On the basis of spectral evidence, the structures of the active compounds were identified as manassantin A and B. Manassantin A and B inhibited phorbol 12-myristate 13-acetate (PMA)-induced homotypic aggregation of the human promyelocytic leukemia HL-60 cells without cytotoxicity with MIC value of 1.0 and 5.5 nM, respectively.

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.

In order to develop natural food preservatives, the ethanol and water extracts of the Saururus chinensis Baill were prepared. Antimicrobial activity was examined against 10 kinds of harmful microorganisms. The ethanol and water extracts showed the most active antimicrobial activity against B. subtilis and E. coli. The ethanol extract showed stronger antimicrobial activity than that of the water extract. However, the extracts did not show any antimicrobial activity against lactic acid bacteria and yeast. The minimum inhibitory concentrations (MIC) of ethanol extracts against B. subtilis and E. coli were 5 to 10 mg/mL, respectively. Antimicrobial activity of the ethanol extract was not destroyed at 40-12$0^{\circ}C$ and pH 3∼11. The ethanol extract was fractionated in the order of hexane, diethyl ether, ethyl acetate, and water fractions. The highest antimicrobial activity was found in the diethyl ether fraction.
