  • This study was performed to develop functional vinegar by using cucumbers through two stages of fermentation. The alcohol content was maximized (7.8%) after 6-days of alcohol fermentation at $25^{\circ}C$ by adjusting the initial sugar concentration to $15^{\circ}Brix$, and vinegar with an acidity of 5.8% was obtained after 12-days of acetic acid fermentation at $30^{\circ}C$. The major sugars in the produced vinegar were glucose and fructose, which were present in concentrations of 3,067.26 and 395.73 mg%, respectively. The major organic acids were acetic acid and succinic acid, which were present in concentrations of 4,410.5 and 841.11 mg%, respectively. The total free amino acid content of the cucumber vinegar was 181.45 ${\mu}g/mL$ and citrulline, valine, aspartic acid, asparagine, and ornithine were the major amino acids. The inorganic components included various alkaline elements, such as K, Ca, and Mg. In addition, experimental methods to assess the DPPH and $ABTS^+$ radical-scavenging ability, reducing power, and ${\beta}$-carotene bleaching activity showed that the cucumber vinegar had strong antioxidant properties. The total polyphenol content, which are the major components responsible for the antioxidant activities of the cucumber vinegar, was 40.14 mg/100 mL. The cucumber vinegar showed significantly higher hepatic aldehyde dehydrogenase activity when compared to the alcoholic control (negative) and the marketing drink (positive), resulting in decreased plasma acetaldehyde concentrations in rats. These results demonstrate that cucumber vinegar possesses antioxidant properties and holds great promise for use in preventing hangovers.

  • Cucumber fermentation has been used as a means of preservation. This study was performed to investigate the effects of fermented cucumber beverage (CF) containing beneficial materials for an ethanol hangover based on Hovenia dulcis (SKM) on ethanol-induced hepatotoxicity. Male Sprague-Dawley rats were randomly divided into three groups: ethanol control, ethanol plus SKM, and ethanol plus CF+SKM. SKM or CF+SKM was orally administered at a dose of 7 mL/kg body weight once per day for 5 weeks. Control rats were given an equal amount of water. CF+SKM significantly lowered plasma ethanol levels, whereas SKM tended to decrease the levels compared to the control. Both SKM and CF+SKM significantly lowered the plasma acetaldehyde levels and serum transaminase activities compared to those in the control. SKM and CF+SKM did not affect hepatic alcohol dehydrogenase activity; however, it significantly inhibited cytochrome P450 2E1 (CYP2E1) activity. Hepatic aldehyde dehydrogenase (ALDH) activity was significantly higher in the SKM and CF+SKM groups than that in the control group. Plasma acetaldehyde concentration was significantly correlated with hepatic CYP2E1 (r=0.566, p<0.01) activity and ALDH (r=-0.564, p<0.01) activity. Hepatic superoxide dismutase and catalase activities as well as glutathione content increased with the SKM and CF+SKM administration, whereas lipid peroxide content decreased significantly. Furthermore, SKM and CF+SKM lowered plasma and hepatic lipid content and lipid droplets compared to those in the control group. These results indicate that SKM and CF+SKM exhibit hepatoprotective properties partly by inhibiting CYP2E1 activity, enhancing ALDH activity and stimulating the antioxidant defense systems in ethanol-treated rats.

  • Lemon myrtle (Backhousia citriodora), a plant in the Myrtaceae family, is native to the semitropical rain-forests of Queensland and is presumably the most commercialized native spice. In Australian thousands of lemon-myrtle trees are under tillage. This study was carried out to investigate the alcohol metabolism, hepatoprotective effects and antidiabetic, tyrosinase inhibitory activity of hot-water (LMW) and 80% ethanol (LME) extracts from lemon-myrtle leaves. The alpha-glucosidase (${\alpha}$-glucosidase) inhibitory activities of the LMW and LME extracts were 7.66% and 40.29% at 1 mg/ml (p<0.05), respectively. The tyrosinase inhibitory activity of the LME extract was about 38.26 % at 1 mg/ml. The effects the LMW and LME extracts had on alcohol-metabolizing activities were determined by measuring the generation of reduced nicotinamide-adenine dinucleotide (NADH) by acetaldehyde dehydrogenase (ALDH) and alcohol dehydrogenase (ADH). The ADH activities of the LMW and LME extracts significantly increased in a dose-dependent manner and were about 154.40% and 192.03% at 1 mg/ml, respectively (p<0.05). The ALDH activities of the LMW and LME extracts also significantly increased in a dose-dependent manner and were about 151.14% and 192.34% at 1 mg/ml, respectively (p<0.05). At $100{\mu}g/ml$, the LMW and LME extracts showed significant protective effects against tacrine-induced cytotoxicity in Hep G2 cells. The results suggested that Backhousia citriodora leaf extracts have the potential to be significant sources for natural health products.

  • This study was performed using animals to confirm the effect of tourmaline-ionized water (TIW) the properties of which were changed by tourmaline energy and electric discharge. In the ICR mice fed high-fat diet, body weight increasing rate of the TIW-treated group (Exp) was generally decreased and moreover exhibited significance at 11th week (P<0.05) compared with the control (Con) group fed distilled water, although water intake of the Exp group was lower than that of the Con group. In the ICR mice with $CCl_4$-induced hepatotoxicity, AST and ALT activities of the Exp group were not significant but showed some decreasing trend, and histological damage of liver was less compared with thatof the Con group. On the study of ethanol-induced hangovers in Sprague-Dawley rat, blood alcohol concentration was significantly decreased (P<0.01), activity of GST, antioxidant enzyme related to the alcohol metabolism, was increased in liver tissue (P<0.05), and AST and ALT show a tendency to be decreasedin the Exp group. These results suggest that drinking TIWhas not only some obesity preventing effect but also an alcohol detoxification effect and liver protecting effect in vivo. It is supposed due to a structural change of water cluster and a property which maintains the changed structure through tourmaline energy and electric discharge. Therefore, TIW has a potentiality to be developed as functional water with several beneficial effects as well as for daily drinking, but further study on the mechanism related with efficacy will be necessary.

  • This study investigates the effects of a hangover beverage (MIX) that contains minerals (highly-salty mineral water, HSMW) and several medicinal plant extracts, on antioxidant and alcohol-metabolizing enzymes in alcohol administered Sprague-Dawley rats. HSMW is pumped from below the sedimentary rock layer of Dadaepo, Busan, South Korea, which is 1,050 m below the land surface; it tastes salty, like sea water. In terms of medicinal plant extracts, the total phenolic and flavonoid contents of Rubus coreanus and Cornus officinalis were measured as being significantly higher than those in Curcuma longa. The results suggest that treatment with MIX significantly increases superoxide dismutase (SOD) activity and DPPH radical scavenging activity. In the 10% HSMW-, for MIX- and company product (CP)-treated groups, the concentration of blood alcohol was significantly reduced 1~5 hr after alcohol loading, compared to that in the control group. In hepatic alcohol-metabolizing enzyme activities, alcohol dehydrogenase (ADH) activity was found to be higher in the MIX- and CP-treated groups than in controls, whereas acetaldehyde dehydrogenase (ALDH) activity was significantly higher in the CP-treated groups than other groups. This study concludes, therefore, that MIX (HSMW) minerals, like as Zn, Ca, Mg, Mn, and others stimulate alcohol-metabolizing enzymes, while the antioxidants of plant extracts prevent the damage otherwise incurred by alcohol toxicity. These results suggest that the hangover beverage (MIX) alleviates alcohol hangover symptoms by stimulating activities related to hepatic alcohol-metabolizing enzymes and antioxidant effects.

  • Microbulbifer sp. was used to acquire the degrading products from Ecklonia cava (DPEC) and the products were investigated to determine the physiological activities. Firstly, 2,2-diphenyl-1-picrylhydrazyl (DPPH) activity and superoxide dismutase (SOD) assay were about 84.1% and 89.6% at 2.5 mg/ml, respectively. In addition, nitrite scavenging ability was shown to be 56.3% at 0.5 mg/ml on pH 1.2. ${\alpha}$-Glucosidase inhibitory activity was increased in a dose-dependent manner and was about 58.7% at 2.5 mg/ml. To determine the influence of DPEC on alcohol metabolism, the generating activity of reduced-nicotinamide adenine dinucleotide (NADH) by alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) were measured. Facilitating rates of ADH and ALDH activities by DPEC were 123.3% and 215.2% at 2.5 mg/ml, respectively. For analyses of anti-wrinkling and whitening effects, its elastase and tyrosinase inhibitory activities were measured and were about 73.1% and 42.2% at 2.5 mg/ml, respectively. These results indicated that DPEC has valuable biological attributes owing to its antioxidant, nitrite scavenging, and alcohol metabolizing activities and ${\alpha}$-glucosidase, elastase, and tyrosinase inhibitory activities.

  • 옻나무 유래 Flavonoid(F)는 항암 효과, 숙취해소 등의 효능이 있으며, 신장의 기능을 촉진하고 생식에도 영향을 준다고 알려져 있다. 그 주성분으로는 fustin, fisetin, sulfuretin, butein으로 추정되고 있다. 본 연구팀의 예비실험에서 성숙 흰쥐에게 F를 30일간 5mg씩 구강투여 하여 정소 중량 및 혈액 내 Testosterone 농도를 분석한 결과, 정소 중량이 증가되고 혈중 Testosterone의 농도도 대조구에 비해 유의적으로 높은 결과를 얻었다. 이에 본 연구의 목적은 옻나무 유래 F가 성숙 수컷 횐쥐의 생식 기능에 직접 미치는 영향을 알아보고자, 흰쥐 Leydig 세포를 분리, 회수하여 체외배양에서 Testosterone농도를 조사하였다. SD계 흰쥐(약 12주령, 체중 250g 전후)의 정소를 적출 한 후, Leydig 세포를 회수하기 위해 0.25% collagenase용액에 넣어 34$^{\circ}C$에서 15분간 진탕 수조에서 배양하였다. 배양된 정소조직은 D-MEM 배양액(10% FCS와 antibiotics 첨가)으로 2~3회 세척한 후 세포 수를 1$\times$$10^{6}$ cells/$m\ell$/well로 분주하여, F(20, 40, 80, 160ng), IGF-I(50, 100ng) 와 LH(10, 100ng) 용량별 각각 첨가하여 배양하였다. 각 처리 후, 배양시간(3, 6, 12, 24, 36시간)에 따라 배양액을 회수하여 COAT-A-COUNT(DPC, USA) kit를 이용하여 RIA방법에 의해 Testosterone을 분석한 결과는 다음과 같다. 대조구 Leydig 세포를 36시간까지 체외 배양하여 Testosterone의 농도를 조사한 결과, 24시간 배양구가 가장 높은 농도를 나타내었다. F를 단독 첨가하여 12시간 배양한 실험에서 F 80ng 첨가구에서 유의적으로 높은 농도를 보였다. LH 10ng 및 100ng 첨가구의 시간별 변화로는, LH 10ng 첨가구에서는 6~12시간 이후, LH 100ng 첨가구에서는 3~6시간 사이에서 유의적인 증가를 보였다. 또한, LH 10ng 첨가 실험에서는 LH 10ng+F 40ng에서 12시간 배양 시, 유의적으로 높은 Testosterone 분비를 확인하였으며, LH 100ng을 첨가하여 3시간 배양 시는 각 처리구 마다 높은 유의적 차이를 보였다. 한편, GH에 관여하는 IGF-I 첨가효과를 비교 검토한 결과, LH 100ng+IGF-I 100ng, 6시간 배양구에서 유의적으로 높게 나타내었다. 이상의 결과로, F 단독 처리 시의 적정량은 약 80ng이며, 흰쥐 정소 Leydig 세포의 Testosterone분비를 촉진하는 작용을 하는 것으로 사료되며, 특히 LH+F구에서 Testosterone분비를 더욱 향상시킴으로써 정소 Leydig 세포의 Androgen 생성을 촉진시키는 역할이 있는 것으로 보여진다 따라서 옻나무 유래 F는 포유동물의 생식기능에 중요하게 작용하는 것으로 사료된다.

  • Physiological activities of hot water (BRW) and 80% ethanol (BRE) extracts from brown rice were investigated in this study. The highest activity (94.9%) of nitrite reductase was observed for BRE at 1 mg/ml at pH 1.2, while the activity for BRW was about 75.4% under the same conditions. The inhibitory effects of BRW and BRE on xanthine oxidase activity were about 39.0 and 72.9% at 10 mg/ml, respectively. The digestibility of starch was lower for brown rice than for milled rice and the highest inhibition (93.1%) of ${\alpha}$-glucosidase activity occurred with BRE. Superoxide dismutase (SOD)-like activities of BRW and BRE were weakly increased in a dose-dependent manner and were about 56.4 and 44.9% at 10 mg/ml, respectively. The influences of BRW and BRE on alcohol metabolizing activity were determined by measuring the generation of reduced nicotinamide adenine dinucleotide (NADH) by alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH). Increases in ADH and ALDH activities were only detected with BRE.

  • $Microbulbifer$ sp. AJ-3 was used to acquire the degrading products from $Capsosiphon$ $fulvescens$ (DPCF), which were investigated to determine its physiological activities. A crude enzyme extract from $Microbulbifer$ sp. AJ-3 hydrolyzes polysaccharide substrates such as agar, agarose, alginic acid, fucoidan, laminaran, starch, and chitin. Among them, agarose, laminaran, and alginic acid showed higher activities, especially alginic acid. The antioxidant activity of DPCF was measured by using 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and superoxide dismutase (SOD)-like activities and were about 32% and 93% at 2 mg/ml, respectively. In addition, the nitrite-scavenging activity of DPCF was about 82%, 53%, and 12% at pH levels of 1.2, 3.0, and 6.0, respectively. To determine the influence of DPCF on alcohol metabolism, the generating activity of reduced-nicotinamide adenine dinucleotide (NADH) by alcohol dehydrogenase (ADH) was measured. The facilitating rate of ADH activity by DPCF was 130% at 2 mg/ml. The tyrosinase inhibitory activity of DPCF was slightly increased in a dose-dependent manner and was about 28% at 2 mg/ml. These results indicated that the enzymatic products from DPCF have a strong antioxidant, nitrite scavenging, and alcohol metabolizing activity.
