The suppressive effects of glutathione-enriched Saccharomyces cerevisiae FF-8 strain (FF-8 GY) on alcoholinduced hepatotoxicity have been studied. FF-8 GY (256 mg/L) from the fermentation at a large scale bioreactor was used. Either of 5% FF-8 GY or 5% commercial glutathione-enriched yeast extract (GYE) with or without 30% alcohol was tested with rats for 4 weeks. FF-8 GY and GYE were found to reduce those alcohol-elevated serum alanine aminotransferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) activities. Blood alcohol and acetaldehyde were also decreased by FF-8 GY and GYE. Interestingly, FF-8 GY drastically increased both hepatic alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities in comparison to GYE group, thus FF-8 GY would be more effective in blood alcohol and acetaldehyde reduction. Attenuated lipid droplet accumulation in hepatocytes was observed in both FF-8 GY and GYE when alcohol stimulated the accumulation. Therefore, FF-8 GY may be useful to protect liver from alcohol-induced hepatotoxicity.

Objectives : Alcohol hangover is a common phenomenon which basically occurs after heavy drinking. Moreover, heavy alcohol consumption leads to acute and chronic diseases. We investigated the effect of herbal mixture (SJ) on alcohol metabolism in serum or/and liver. Methods : 5W-old Sprague Dawley rats were used for the study. To overnight fasted rats, 0.9% saline or SJ extract was administrated per os before alcohol treatment. Then, 40% alcohol was orally administrated to all rats in 30 mins. Ethanol, acetaldehyde concentrations, alcohol dehydrogenase (ADH), acetaldehyde dehydrogenase (ALDH) activities were measured by assay kits. Aspartate aminotransferase (AST) and alanine transaminase (ALT) were measured by analyzer. Results : Ethanol and acetaldehyde concentrations lowered in SJ groups compared with CON group. Especially, acetaldehyde concentration significantly decreased in SJ groups compared with CON group. AST and ALT levels tended to increase in SJ groups compared with CON group but there was no significant difference between CON group and SJ groups. ADH activity in serum was higher in SJ groups than CON group but no significant difference in liver. ALDH activity in both serum and liver showed significantly increased in SJ groups compared with CON group. Conclusions : Treatment of SJ extract showed not only reducing concentration of alcohol and acetaldehyde but also increasing activities of ADH and ALDH. These results suggest SJ may influence in alcohol metabolism via control of metabolic enzyme activities and metabolite. Therefore, SJ, herbal mixture, might have a function of preventing hangover after drinking alcohol.

The term "hangover" refers to symptoms such as headache, heartburn, nausea, and dizziness caused by acetaldehyde created through alcohol decomposition in the body after alcohol intake. Many scientists have conducted research on diverse drugs, foods, and medicinal herbs aimed at eliminating hangovers. However, research on metabolism to objectively verify or measure their effects on hangover symptoms has been lacking. Accordingly, in this study, deep sea water minerals were administered orally at varying concentrations to rats that consumed alcohol, and changes in the levels of amino acids in their bodies were measured using nuclear magnetic resonance spectroscopy to gauge the minerals' effects on hangover symptoms. Thus far, biochemical research on hangover cures has been confined to basic research measuring changes in the levels of alcohol dehydrogenase and acetaldehyde dehydrogenase as well as in the concentrations of ethanol, acetaldehyde, and acetate using spectroscopes such as enzyme-linked immunosorbent assay kits or gas chromatography-mass spectrometers. In comparison, this study presents pharmacokinetic research that simultaneously tracked biomaterials including amino acids and organic acids, metabolites associated with hangover, to clarify hangover mechanisms more specifically. In addition, this study examined hangover mechanisms without an external supply of tracked materials not overlapping with alcohol metabolism-related materials, such as external amino acids and sugars.

본 연구에서는 숙취용 음료를 개발하기 위하여 알코올을 투여한 흰쥐를 대상으로 흑마늘 추출물 130 mg/kg과 260 mg/kg을 각각 40% 알코올(5 g/kg, B.W.) 투여 30 분 전과 30 분 후에 경구 섭취시키고 1, 3 및 5 시간 동안 경시적으로 혈액 중의 알코올 및 아세트알데히드 농도와 간조직 중의 alcohol dehydrogenase (ADH) 및 acetaldehyde dehydrogenase (ALDH)의 활성과 간지표 효소인 alanine aminotransferase (ALT) 및 aspartate aminotransferase (AST)의 활성을 측정하였다. 알코올 투여 30 분 전에 흑마늘 추출물을 경구 섭취시켰을 때 혈 중 알코올의 농도는 시간 경과에 따라 급격하게 감소하였으며 알코올 투여 후 5 시간 경과 시 알코올 투여 대조군에 비하여 흑마늘 추출물 투여군이 28.5%로 감소하는 경향을 나타내었다. 또한 혈 중 아세트알데히드의 농도는 알코올 대조군에 비하여 흑마늘 추출물 투여군이 매우 감소하였다. 알코올 투여 30 분 후 흑마늘 추출물을 투여한 것은 알코올 투여 30 분 전의 실험군과 비슷한 경향을 나타내었다. 간 조직중의 ADH 활성은 정상군과 흑마늘 추출물 투여군 모두 큰 변화는 찾아 볼 수 없었으나 ALDH의 활성은 약간의 차이를 확인할 수 있었다. 혈청 ALT, AST 활성은 대조군과 흑마늘 추출물 간에 유의적인 차이는 나타내지 않았으나, 흑마늘 추출물의 섭취가 간 기능에 나쁜 영향을 미치지 않는 결과로 보아 안전성이 있다고 사료된다.

Persimmon has been known to help alcohol intoxication in Korea for a long time and is prepared as a processed food. The effect of dried persimmon snacks on alcohol metabolism was determined in vivo. Eight Korean men (25~27 years old) were administered 3.5 mL/kg of alcohol (22.5%, w/v) with or without a dried persimmon snack (2g/kg). The levels of alcohol in the blood and of acetaldehyde in the blood and the urine were determined by alcoholmeter and assay using alcohol dehydrogenase and HPLC, respectively. All subjects showed decreased levels of alcohol in blood, and six subjects showed a decrease of alcohol in urine after consumption of ethanol with dried persimmon snacks. Concentration of acetaldehyde in the blood an urine decreased significantly in three and five of the eight subjects, respectively. Reduction was more significant for alcohol than for alcohol than for acetaldehyde with administration of ethanol and dried persimmon snacks. This in vivo result suggests that dried persimmon snacks are effective in decreasing th concentration of alcohol after alcohol intake.

본 연구에서는 알코올을 섭취한 흰쥐에서 알코올 대사와 혈액가스 불균형에 대한 꾸지뽕 나무 뿌리 추출물 (이하 CTE)의 효과를 확인하고자 하였다. 알코올을 10 ml/kg의 농도로 흰쥐에게 경구 투여하였고, 섭취 30분 후 CTE를 500 mg/kg 및 750 mg/kg의 농도로 투여하였다. 혈액은 알코올 섭취 1시간, 3시간, 5시간 후 꼬리 정맥을 통하여 채취하였다. 양성 대조군은 시판되고 있는 숙취해소 음료 (컨디션)를 사용하였다. 약물 처리는 모두 단회 경구 투여로 진행되었다. CTE의 섭취는 흰쥐의 혈액과 간 조직 내 알코올 대사 효소인 알코올 분해효소 (alcohol dehydrogenase)와 아세트알데히드 분해효소(acetaldehyde dehydrogenase)를 증가 또는 유지시킴으로써 혈중 알코올 농도를 감소시켰다. 또한, CTE는 알코올섭취에 의한 혈액가스 (pH, $CO_2$, $HCO_3{^-}$, lactic acid)의 불균형을 회복시켰다. 결론적으로, CTE는 현재 시판되고 있는 숙취해소음료 보다 우수한 숙취 해소 효과를 나타내었다. 따라서 본 연구자는 CTE를 숙취 해소 및 예방을 위한 천연물 유래의 안전하고 새로운 물질로써 제시하는 바이다.

Objectives : This study was designed to investigate the effects of Chungganhaeju-tang on expression of alcohol metabolizing enzymes, cell viability and alcohol-induced apoptosis. Materials and Methods : For this study, the human hepatoma cell line HepG2 was used. HepG2 cells were treated with ethanol-or acetaldehyde, chungganhaeju-tang, anti-Fas neutralizing antibody and were investigated by using quantitative RT-PCR, MTT and Trypan blue exclusion assays. Results : The results are summarized as follows: 1. Quantitative RT-PCR analysis demonstrated that ethanol-or acetaldehyde-mediated increase of ALDH gene expression was not affected by Chungganhaeju-tang treatment. 2, Ethanol-or acetaldehyde-induced apoptosis was remarkably inhibited by Chungganhaeju-tang in a dose-dependent manner. 3, Ethanol-or acetaldehyde-induced apoptosis was significantly blocked by anti-FasL neutralizing antibody, suggesting apoptosis induced by alcohol might be mediated by FasL/Fas signaling pathway. Conclusions : Taken all together, these results indicate that the FasL/Fas signaling plays a critical role in alcohol-induced apoptosis and Chungganhaeju-tang increases viability of liver cells by suppression of the FasL/Fas-mediated apoptosis-signaling pathway.

The purpose of this study is to investigate the hangover relieving effect of HO-series. HO-S1 is an herbal mixture, which consists of extracts from Flower of Pueraria lobata Ohwi, Glycyrrhiza glabra Linné, Fruit of Lycium chinense Miller, Poria cocos Wolf, Acanthopanax sessiliflorum Seeman, Scutellaria baicalensis Georgi, Atractylodes lancea De Candlle and Zingiber officinale Roscoe. HO-S2 is a candidate that has been performed to ultra filtration based on HO-S1. HO-S3 is a mixture of amino acids and vitamins based on HO-S2. HO-01 is the final beverage base produced based on HO-S3. The antioxidant activity of HO-series was similar to that of vitamin C or trolox. The production of t-BHP induced reactive oxygen species(ROS) was significantly blocked in the presence of HO-series. In vivo study, AUC of alcohol and acetaldehyde concentrations in HO-S2 and HO-S3 treated groups significantly decreased. Hepatic alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH) activity were significantly higher in HO-S2 and HO-S3 treated groups. And 2E1 activity and glutathione were significantly elevated, while the malondialdehyde level was not significantly in liver tissue. After alcohol exposure, the sensitivity scores of blood alcohol and acetaldehyde concentration and hangover symptoms were significantly decreased in the HO-01 intake group compared with the non-intake group. ALDH activity was significantly increased in the HO-01 intake group. HO-series have antioxidant activity and a protective effect from ROS. HO-S2, HO-S3 and HO-01 are potentially highly beneficial in relieving hangover, as it scavenges reactive free radicals and boosts the endogenous antioxidant system.

본 연구에서는 숙취해소에 좋은 것으로 알려진 식품 소재의 주요 아미노산을 포함하여 효소 활성에 영향을 미치는 것으로 알려진 아미노산을 선택하였고, 효소 활성도가 상대적으로 높은 yeast와 rat liver 유래의 ADH 및 ALDH 효소를 대상으로 알코올 대사에 관련된 효소 활성의 촉진 효과에 대하여 검토하였다. Rat liver 유래의 ADH 활성은 처리한 아미노산 중에서 arginine에서 가장 높았다. Arginine의 첨가 농도를 달리하여 효소 활성을 측정한 결과 $10{\sim}50\;mg$/ml 농도에서 $118{\sim}120.6%$로 양성대조구의 90.6% 보다 약간 높은 것으로 나타났다. 또한, yeast 유래의 ADH 활성은 methionine에서 가장 높은 활성을 보였고, methionine의 처리 농도를 달리한 경우에서는 첨가 농도 의존적으로 높은 활성을 보였다. Rat liver 유래의 ALDH 활성은 methionine이 가장 높은 활성을 보였다. Methionine의 첨가 농도별 측정에서는 10 mg/ml에서 30 및 50 mg/ml 첨가 농도에서 보다 높은 활성을 보였으며, 이들 모든 처리 농도에서 양성대조구 보다 상당히 높은 활성을 보였다. 한편 yeast 유래의 ALDH 활성은 각 아미노산별 큰 차이는 없었으나, arginine에서 높은 활성을 보였다. Arginine의 첨가 농도별 측정에서는 처리 농도 의존적으로 활성이 약간씩 증가하는 경향을 보였으며, 양성대조구 보다 높은 활성을 나타내었다. 효모 유래 ALDH 및 rat liver 유래 ADH 효소 활성을 촉진시키는 작용을 가진 arginine을 효모 배양에 첨가시킬 경우 세포 내 ALDH 및 ADH 활성 염색 정도가 증가함으로써 arginine은 ALDH 및 ADH 활성을 촉진시키는 효능이 in vivo 실험계에서도 확인되었다. 이상의 실험 결과에서 아미노산 중에서는 arginie과 methionine이 ADH 및 ALDH 활성을 촉진시키는 작용에 의해 알코올 분해뿐만 아니라 acetaldehyde의 분해도 촉진시킬 가능성이 높아 숙취해소 효과는 물론 간 보호 효과도 동시에 있을 것으로 시사 되어 진다. 따라서 arginine과 methionine과 같은 아미노산을 주류 제품에 첨가하게 될 경우 숙취해소 경감과 간 보호 효능을 어느 정도 나타낼 수 있을 가능성이 제기되었다.

Alcohol is the most widely psychoactive drug and has known in almost all civilization since ancient time. Recently increase consuming alcoholic beverages, alcohol is on of the major public health problems in the world. Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) play important roles in the metabolism of alcohols and aldehydes. The drink consists of medicinal herbs, Puerariae Radix, Phyllostachyos Folium, Citri Pericarpium, Polygonati Rhizoma, Rehmanniae Rhizoma (Vinegar), which have been widely used in oriental medicine. This study was designed to investigate effects of medicinal herbal drink (MHD) on alcohol metabolism in drunken SD rats subjects. In experiment, rats were treated to ethanol (EtOH, 3 g/kg, PO) at 60 min. after saline (CON) or MHD (1 ml/kg, PO) administration. The blood alcohol concentration (BAC), blood acetaldehyde concentration (BALC) activities of ADH, ALDH, AST and ALT were significantly decreased in MHD group than in control group as a time-dependent manner. And drinking water volume in MHD group with duplicate treatment, were significantly decreased than in CON group. These results suggested that MHD intake could give an influence upon the reduction in BAC and BALC may alleviate acute ethanol-induced hepatotoxicity by altering alcohol metabolic enzyme activities.
