  • Cotinine, one of nicotine metabolites, has been blown to reduce 4-(methylnitro samino)-1-(3-pyridyl)-1-butanone(NNK)- induced $O^{6}$MeG DNA adducts significantly in A/J mice when administered together with NNK. In order to examine the effects of phyto-extract mixture on the conversion of cotinine from nicotine, cellular and clinical experiments were carried out. When the phyto-extract mixture was added to culture media, human liver cells (FLCFR5) produced cotinine from nicotine 2~3 times compared to the control. The phyto-extract mixture which was microinjected into Xenopus oocyte along with nicotine showed the almost similar production of cotinine compared with the results of hepatic cell culture. In clinical test employing 17 to 20 healthy men, concentrations of urinary cotinine derived from smoking after taking photo-extract mixture increased up to 2 times compared to the control group. These results indicatethat the phyto-extract mixture can increase the metabolic efficiency of nicotine to cotinine, leading to the reduced formation of $O^{6}$MeG DNA adducts.

  • The antioxidants and packaging methods affecting on lipid oxidation of the plain dried large anchovy were investigated. Antioxidants resulted in decrease of lipid oxidation of dried large anchovy. The addition of BHT remarkably repressed lipid oxidation during storage of the dried large anchovy at $37^{\circ}C$, followed by ${\alpha}-tocopherol$, rosemary extract and sage extract. The addition of rosemary extract mixed with 0.1{\%} {\alpha}-tocopherol$ showed similar effect to BHT during storaBe at $25^{\circ}C\;in\;0.1{\%}$ rosemary extract mixed with $0.1{\%}\;{\alpha}-tocopherol$. When the dried anchovy were packed in polyethylene film after treatment with antioxidants, the vacuum package increased the antioxidative effect in repression of lipid oxidation during storage of dried large anchovy.

  • ${\gamma}$-aminobutyric acid (GABA) is a non-proteinogenic amino acid biosynthesized through decarboxylation of L-glutamic acid by glutamic acid decarboxylase. GABA is believed to play a role in defense against stress in plants. In humans, it is known as one of the major inhibitory neurotransmitters in the central nervous system, exerting anti-hypertensive and anti-diabetic effects. In this report, we wanted to enhance the GABA production from the barley leaf and corn silk by culturing them with lactic acid bacteria (LAB). The barley leaf and corn silk were mixed with various weight combinations and were fermented with Lactobacillus plantarum in an incubator at $30^{\circ}C$ for 48 h. After extracting the fermented mixture with hot water, we evaluated the GABA production by thin layer chromatography and GABase assay. We found that the fermented mixture of the barley leaf and corn silk in a nine to one ratio contained a higher level of GABA than other ratios, meaning that the intermixture and fermentation technique was effective in increasing the GABA content. We also tested several biological activities of the fermented extracts and found that the extracts of the fermented mixture showed improved antioxidant activities than the non-fermented extracts and no indication of cytotoxicity. These results suggest that our approach on combining the barley leaf and corn silk and its fermentation with LAB could lead to the possibility of the development of functional foods with high levels of GABA content and improved biological activities.

  • In this study, the cell viability, radical scavenging ability, elastase activity, moisturizing activity, and antimicrobial activity of mixed fermented extract of vitamin tree fruit, acai palm fruit, mango, lemon, apricot and blueberry as an active ingredient were measured. The experiment was performed at three concentrations(0.5 / 1.5 / 2%), since cytotoxicity was not shown at these three concentrations. Based on this, a radical scavenging experiment was conducted to compare with L-ascorbic acid, a representative raw material of an antioxidant material. The results showed that the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging ability was 95.1 ± 0.6%, 94.3 ± 0.7%, 95.3 ± 0.6%, 95.1 ± 0.7%, 95.1 ± 0.3%, 95.5 ± 0.3%, and 95.4 ± 0.4% respectively, when the concentration of the mixed fermentation extract was 2%. As the concentration increased at the three concentrations (0.5/1.5/2%) and the content of blueberry extracts increased, sample 7 showed excellent elastase activity at a concentration of 2% to 0.9 cm, such as retinol crystal, and moisturizing activity was also found to be 71.5%, 75.6%, and 81.6%, respectively. Particularly, at the 2% concentration of the mixed fermented extract, the antibacterial activity effect on Propionibacterium was very excellent in sample 7. Therefore, it is considered that it is worth developing the mixed fermented extracts of 2% concentration as a cosmetic component with antioxidant, moisturizing, and antibacterial properties.

  • In this study, antioxidant and anti-inflammatory effects of ethanol extracts from medicinal herb mixtures were investigated in vitro. Contents of total polyphenols in ethanol extracts from Houttuynia cordata Thunb. (HC), Carthamus tinctorius L. (CT), and MIX-2 (Houttuynia cordata Thunb., Acanthopanax gracilistylus Smith, Carthamus tinctorius L., Kalopanax pictus) were 58.98, 60.79 and 57.74 mg/g respectively. Radical scavenging activities of the ethanol extracts were examined using ${\alpha},{\alpha}$-diphenyl-${\beta}$-picrylhydrazyl radicals and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) assay. Anti-inflammatory effects of ethanol extracts from medicinal herbs composites were examined using 5-lipoxygenase (5-LO), cyclooxygenase-2 (COX-2) and nitric oxide (NO) inhibition assays. The ethanol extracts from medicinal herb mixtures showed higher 5-LO and COX-2 inhibition activities than those from single medicinal herbs. The ethanol extracts from medicinal herb mixtures also showed strong anti-inflammatory activity through inhibition of NO production.

  • Recently, arbutin, oil soluble licorice extact (GLY), ascorbyl glucoside (AA2G), and ethyl ascorbyl ether (EAE) have been widely used as functional whitening ingredients. To Investigate which combination between the above agents could be more effective for whitening effect, tyrosinase activity and MSH-induced melanin production in B-16 melanoma cells were investigated. Both GLY and arbutin dose-dependently inhibited purified tyrosinase activity. The inhibitory effects of GLY with AA2A or EAE on Drosinase activity were more potent than those of GLY alone, whereas that of arbutin with other ingreadients did not show those effects. In MSH-induced melanin production in B-16 melanoma cells, the mixture of Gly and EAE more significantly reduced melanin formation than Gly alone. Stability of mixture of GLY, arbutin, AA2A and EAE exposed at the temperature of $25^{\circ}C\;or\;45^{\circ}C$ for 30 days were also investigated. All of the combinations of whitening agents did not show any critical changes in their composition stability. These data suggest that the combination of GLY and vitamin C derivatives such as AA2G and EAE may be useful for the promotion of whitening effect.

  • Atopic dermatitis is a chronic, relapsing inflammatory skin disease. This study aimed to investigate the therapeutic benefits of Aronia melanocarpa (AM) and Moringa oleifera seed extract (MO) on experimental atopic dermatitis. We examined the effects of AM or MO and their combination on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis in BALB/c mice as well as tumor necrosis factor $(TNF)-{\alpha}$ and interferon $(IFN)-{\gamma}-stimulated$ HaCaT keratinocytes. Mice were orally treated with extract during repeated application of DNCB to shaved dorsal skin. Our results show that treatment with AM and MO in combination reduced histological manifestations such as epidermal hyperplasia and inflammatory cell infiltration. Furthermore, it significantly decreased skin thickness and serum immunoglobulin E (IgE) level compared to the AM or MO alone treated group. Combined extract of AM and MO suppressed expression of $TNF-{\alpha}/IFN-{\gamma}-induced$ T helper 2 (Th2) chemokines such as thymus and activation-regulated chemokine and macrophage-derived chemokine. To sum up, combination of AM and MO suppressed the inflammatory response and serum IgE as an indicator of several allergic diseases in DNCB-induced experimental atopic dermatitis and Th2 chemokine expression in HaCaT cells. This result suggests that combination of AM and MO could be a valuable strategy to improve atopic dermatitis.

  • In the present study, we investigated the quality characteristic of old pumpkin extract treated with enzymes. As a results, all the groups treated with pectinase were better in quality characteristic than control group and the group treated with 0.15%(w/w) pectinase was specially great. All the groups treated with simultaneous pectinase and cellulase were higher in the extraction rate than the groups treated with pectinase or cellulase. The experimental groups were divided into non-treated control(I) and three treatment groups(II- IV) for optimum condition of enzyme treatment. The II and IV groups were treated with 0.15%(w/w) pectinase and 0.15%(w/w) cellulase, respectively, and the ill group was treated with both 0.15%(w/w) petinase and 0.05%(w/w) cellulase. Yield for old pumpkin extract of the III group (86.94%) was higher than that of other groups, but there were no significant difference among the groups in soluble solide content and pH of the extract. Reducing sugar and total sugar contents in the ill group were 2.81% and 4.60%, respectively. Total carotene content in the II group (5.36 mg%) was higher than other groups. Old pumpkin extracts in all the groups showed nitrite-scavenging ability to pH 1.2, 3.0 and 4.0. Total free amino acid content in the III group (176.7 mg%) was higher than other groups. Citrulline contents in the II and III groups were detected 1.66 and 1.41 mg%, respectively but the contents in other groups were not detected.
