  • To develop new therapy for prevention and treatment of hair loss is very important according to increase of the number of hair loss people. The aim of this study was to investigate the hair growth promoting effects of pectin lyase-modified red ginseng extract (GS-E3D). We examined antioxidant and anti-inflammatory effects, human hair dermal papilla cells (HHDPC) proliferation, and testoterone-induced $5{\alpha}$-reductase inhibitory effects. GS-E3D show not only 1,1-diphenyl-2-picryhydrazyl (DPPH) radical scavenging activity and xanthine oxidase inhibitory effects as an anti-oxidant property, but also lip-oxygenase and hyaluronidase inhibitory effects as an anti-inflammatory property. Human hair dermal papilla cells proliferation by GS-E3D was higher than those of minoxidil or finasteride, using the positive controls. Moreover, GS-E3D exhibited $5{\alpha}$-reductase inhibitory activities after stimulating by testoterone. The present results indicate that GS-E3D has a potential to be as an hair growth promoting agent for cosmetic materials.

  • In an attempt to find natural sources of antioxidants and whitening agents, Comparisons of the antioxidative and tyrosinase inhibitory activities of various ethanol extracts of Astragali Radix, Atractylodis Rhizoma Alba and Acanthopanacis Cortex were carried out. Comparison of the four ethanol extracts revealed that, Astragali Radix had the highest electron-donating ability(72.5%) and the highest SOD-like ability(26.1%). The xanthine oxidase experiment exhibited a hindrance effect of 88.5% in Atractylodis Rhizoma Alba, 81.1% in Acanthopanacis Cortex, 75.8% in Astragali Radix. A tyrosinase inhibitory activity assay was conducted to evaluate the whitening effects of the extracts, The tyrosinase inhibitory activity was 42.1% in the Acanthopanacis Cortex, 37.2% in the Atractylodis Rhizoma Alba, 6.0% in the Astragali Radix. Based on these results, we suggest that the ethanol extracts of Astragali Radix, Atractylodis Rhizoma Alba and Acanthopanacis Cortex can be used as food and cosmetic ingredients.

  • In order to investigate the effect of Korean green tea, oolong tea and black tea beverage on the antioxidative detoxification in cadmium(Cd) poisoned rat liver, male Sprague-Dawley rat weighing 143$\pm$3.2g were divided into control and experimental groups. The experimental groups were fed standard diet containing 40ppm Cd and were given distilled water(CD), 5% black tea(BT), oolong tea(OT) and green tea(GT), respectively. Tea beverages were extracted from 5G dry leaves of teas in 100ml hot distilled water by the treatment at 85$^{\circ}C$ for 3 min. Liver xanthine oxidase(XOD) activity was increased by the administration of Cd except GT group. Liver superoxide dismutase(SOD), glutathione peroxidase(GSH-px), glutathione S-transferase(GST) activities were decreased by te administration of Cd but did not decreased by the administration of green tea(in GT group). Vitamin E and reduced glutathione contents were significantly decreased in Cd administered groups. Liver lipid peroxide value in Cd administered groups were increased compared to control group, but was not increased in GT group. Serum glutamic oxaloacetic transaminase(GOT) activities in CD, OT, BT groups were higher than control, but that in GT group was similar to control group. Serum glutamic pyruvic transaminase(GPT) activity was not significantly different among various groups. It was concluded that green tea might alleviate peroxidative damage in Cd-administered rat liver by reinforcing antioxidative detoxification system.

  • Free radical scavengers or quenching agents for reactive oxygen species (ROS) present in consumable fruits, vegetables, and beverages have received considerable attention as potential antioxidants, and thus uses for treatment of several human diseases. In this study, grapevine shoot extract (GSE) containing high concentration of resveratrol and viniferine was evaluated for antioxidant potential and inhibition of pro-inflam-matory mediator production. Utilizing 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity and xanthine oxidase (XOD) inhibition assay the GSE showed inhibitory effects of DPPH radical scavenging and XOD activity with the $IC_{50}$/ values of 34.5 and 155 $\mu\textrm{g}$/ml, respectively. In addition, GSE also exhibited the inhibition of prostaglandin E$_2$ (PGE$_2$) and nitric oxide (NO) production in lipopolysaccharide (LPS)-induced mouse macrophage RAW264.7 cells with the $IC_{50}$/ value of 6.4 and 14.5 $\mu\textrm{g}$/ml, respectively. This result suggests that grapevine shoot extract has the potential activity as a natural antioxidant or antiinflammatory agent.

  • The inhibitors of prostaglandin biosynthesis and nitric oxide production by corresponding inducible isozyme have been considered as potential anti-inflammatory and cancer chemopreventive agents. In our continuous search for cancer chemopreventive agents from natural products, we have evaluated the inhibitory potential of PGE$_2$and NO production in lipopolysaccharide (LPS)-induced mouse macrophage RAW264.7 cells. As a result, pinosylvin (3,5-dihydroxy-trans-stilbene), a stilbenoid, mainly found from the heartwood and leaves of the Pinus sylvestris, showed potential inhibitory activity of LPS-induced PGE$_2$and NO production in a dose-dependent manner. Pinosylvin also suppressed the LPS-induced iNOS protein expression. Further study revealed that pinosylvin exhibited antioxidant activity by the DPPH free radical scavenging potential and inhibitory effect of xanthine oxidase activity. In addition, pinosylvin inhibited COX -2 overexpressed human colon cancer cell (HT-29) growth in a time- and dose-dependent manner. These findings suggest that pinosylvin might be a promising candidate for developing cancer chemopreventive agent.

  • Decoction of oriental medicinal preparation is prepared in various manners, and changes of chemical constituents might be occurred depending on the processing techniques. The present study was undertaken to investigate the phγsio-chemical and pharmacological equivalence between two extraction methods of Nokyong-sagunja-Tang. Samples were Prepared as follows ; Sample-I was prepared by simultaneously extracting Sagunja-Tang and velvet antler in one vessel. Sample-lI was prepared by adding velvet antler exact to the water extract of Sagunja-Tang. Both sanples showed similar results of physiochemical parameters such as pH, yield, TLC and HPLC chromatogram, and contents of ginsenoside $Rb_1$ and glycyrrhizin. Also, there were little different between two samples in pharmacological effects such as DPPH free radical scavenging effect, and inhibitory effects on xanthine oxidase, hyaluronidase, trypsin, TBA-Rs formation and hemolysis in vitro. And both samples showed no significant difference in antifatigue activities in mice. These results suggest that there might be little difference between two extraction process when velvet antler added to Sagunia-Tang.
