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.

Saururus chinensis (SC) belongs to the dicotyledonous plants, and its roots, leaves and flowers are white, so it is named three hundred and seconds. It is mainly distributed in Korea, China and Japan. In Korea, it is a native plant distributed in Jejudo and Jirisan areas. It has been known to improve blood circulation, anticarcinogenic effects and purge. However, studies of the efficacy on digestive system is few. This study was conducted to evaluate the effects of oral administered-SC extract in loperimide-induced constipation rats. The amount, weight and water content of the stools were measured. The number and type of stools in the large intestines were measured, and the amount of intestinal mucus was analyzed by serological analysis and histologic special staining. The severity of constipation in SC groups was significantly less than that in control group (non-SC rats). Digital Image processing also showed weaker inflammation on the large intestines of SC groups than that of control group (non-SC group). Especially, with increased dose dependent manner of SC extract, the amount and integrity of intestinal mucus increased. These results suggest that SC extract may prevent the symptoms of constipation.

This paper aims to compare and verify the antibacterial effects of cotton fabrics naturally dyed with extracts of Ulmus davidiana var. japonica Nakai, Caesalpinia sappan, Saururus chinensis, and Artemisia princeps against antibiotic-resistant strains of bacteria. After natural dyeing of the test fabric, Al, Cu, Fe mordants were used. The color fastness against washing, rubbing, and perspiration of the cotton fabrics dyed with the 4 types of extracts were mostly excellent. However, the color fastness against light showed poor results for all four types. As for the antibacterial test method, MRSA (ATCC 33591) was applied to the cotton fabrics dyed with the four kinds of extracts and cultured for 24 hours. After that, the bacteria that proliferated on the fabrics were collected and spread on a solid medium. The bacteria were measured to find out the bacteriostatic reduction rate for the antibiotic-resistant strains. As a result of the analysis, all four extracts showed a high bacteriostatic reduction rate of more than 99% when the copper mordant was used. Even with the lack of a mordant, the bacteriostatic reduction rate was high, at 99.9% for Caesalpinia sappan and 94.6% for Saururus chinensis.

In this study, the functional cosmetic activity of water and ethanol extracts from Saururus chinensis by elicitor treatment are examined. Anti-oxidative activity 1,1-diphenyl-2-picrylhydrazyl and antioxidant protection factor of elicitor treated S. chinensis extract increased in concentration dependent manner as concentration increased from 1.5 mg elicitor/leaf 1 g (group A) to 3.0 mg elicitor/leaf 1 g (group B). Also, 70% ethanol extract showed higher anti-oxidative activity than water extract. Elicitor treated S. chinensis extract showed similar inhibitory effect on elastase activity and whitening effect indicating low effect of elicitor on elastase inhibition and whitening effect. However, it showed high anti-inflammatory and anti-microbial activity compared to control group. Both group A and B showed high anti-inflammatory and anti-microbial activity then control group indicating that elicitor treatment is suitable for biomass method used for industrializing useful compounds. Therefore, elicitor treatment during S. chinensis cultivation will increase bioactivity in the plant source which will yield high quality for industrialization.

In this study, the biological activity of water and ethanol extracts from Saururus chinensis by ultra-fine grinding for functional food source are examined. It is more effective to use ethanol than water when extracting phenolic compounds. Approximately 2.5 times higher extraction yield were shown when it was ultra-fine grinded because the particle size decreases, thereby increasing the extraction yield. Normal grinded sample extracts showed 69.8% of DPPH inhibition effect, while fine grinded and ultra-fine grinded sample extracts showed 70.7% and 83.8% each, respectively. Normal extract, as well as fine grinded and ultra-fine grinded extracts, showed over 97% of ABTS inhibition effect, thereby indicating only a slight difference in the anti-oxidative activity with the grinding method. Higher PF was determined with fine grinded and ultra-fine grinded extracts than the normal grinded extract, while ultra-fine grinded 50% ethanol extracts showed the highest anti-oxidative activity value of 1.8 PF. The fine grinded and ultra-fine grinded particle sizes are smaller than the normal grinded particle size, thus increasing the inhibition rate of the TBARS. Furthermore, the ethanol extract was revealed to have a higher effect than the water extracts. The xanthin oxidase inhibition, on the other hand, was identified as ultra-fine grinded that led to the increase in the enzyme inhibition effect. In the angiotensin-converting enzyme, water extracts with normal grinding did not show inhibition activity, while 50% ethanol extracts showed 24% inhibition activity. Moreover, the ethanol extracts showed higher inhibition effect compared to the water extracts. Ultra-fine grinded 50% ethanol extracts showed a slight antibacterial effect on the Staphylococcus aureus and Escherichia coli, while the other extracts showed none. The result suggests that Saururus chinensis extracts by ultra-fine grinding may be more useful than normal grinding as potential sources due to anti-oxidation, angiotensin converting enzyme and xanthine oxidase inhibition.

The purpose of this study was to investigate the hypoglycemic effect of Saururus chinensis Baill in vitro and in vivo. Methanol extract of S. chinensis Baill inhibited yeast ${\alpha}$-glucosidase activity by 49.8%, which was twice as strong as that of acarbose at a concentration of 0.5 mg/mL in vitro. The effect of S. chinensis Baill methanol extract on the postprandial increase in blood glucose levels was studied in streptozotocin-induced diabetic rats using a carbohydrate load test. Oral administration of S. chinensis Baill extract (500 mg/kg) significantly decreased incremental blood glucose levels at 60 and 90 min (p<0.05) after oral ingestion of starch (1 g/kg). The area under the glucose response curve of the S. chinensis Baill group was significantly decreased compared to that of the control group (p<0.05). The effect of prolonged feeding of S. chinensis Baill was studied in an animal model of type 2 diabetes. Three-week-old db/db mice were fed an AIN-93G diet or a diet containing 0.5% S. chinensis Baill extract for 7 weeks after 1 week of adaptation. Plasma glucose, insulin, and blood glycated hemoglobin levels of the mice fed S. chinensis Baill extract were significantly lower than those of the control group (p<0.05). Therefore, we conclude that S. chinensis Baill is effective in controlling hyperglycemia in animal models of diabetes mellitus.
