Alcohol concentration in the blood was effectively decreased by extracts from Hericium erinaceum hypha cultivated with Artermisia capillaris medium(HEAC), Hericium erinaceum hypha and Artermisia capillaris after dirnking. Also, the activities of alcohol dehydrogenase and acetaldehyde dehydrogenase in the blood was studied. As a result of testing an alcohol concentration in the blood, the alcohol in the blood was not detected after 170 min, in case of HEAC and after 210 min, in case of Hericium erinaceum. Compared to control, each activities of alcohol dehydrogenase of HEAC and Hericium erinaceum hypha was showed up to 154% and 148% respectively. The activities of the acetaldehyde dehydrogenase of both extracts from HEAC and Hericium erinaceum was maintained in the range of 104 to 110% compared to control. In conclusion, such extracts represent significant effect to facilitate decomposition of alcohol.

The physiological activities of cultivated Korean blue mussel (Mytilus edulis) and New Zealand green-lipped mussel (Perna canaliculus) were analyzed and compared. Both hot water extracts of blue mussel flesh (BMF) and green-lipped mussel flesh (GMF) showed increased activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH). BMF showed increased ADH and slightly decreased ALDH activities compared to GMF. 1,1-Diphenyl-2-picrylhydrazyl radical scavenging activity of BMF was higher than that of GMF at the same concentration. BMF and GMF showed similar inhibitory activity against angiotensin converting enzyme at a concentration of 30 mg/mL. These results suggest that cultivated Korean blue mussel has similar physiological activity with New Zealand green-lipped mussel.

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.

Alcohol consumption causes numerous consequences on the health of the human body. Heavy drinking on a daily base has caused liver diseases. Furthermore, some products such as acetaldehyde produced from alcohol metabolism are more toxic than alcohol itself. This study was carried out to evaluate the role of Lactobacillus casei on alcohol metabolism, especially, the removal of the toxic effect of alcohol. The maximum alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities from L. casei were observed at 4 hr of culture. L. casei was confirmed to produce the ADH and ALDH by the SDS-PAGE. From in vivo test using SD rats with 22% alcoholic drink, blood alcohol concentration (BAC), glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) of the rats feeding the medium containing L. casei were lower than those of the rats feeding the medium containing an alcoholic drink only This demonstrates that the ADH and ALDH produced by L. casei have virtual functions to detoxicate the alcohol in vivo and the fermentation broth of L. casei can be used as an alcohol detoxification drink.

Objectives : The aim of this study was to investigate effects of the Sungjuchunggan-tang(Xingjiuqinggan-tang), which has been used for alcoholic diseases in Oriental medicine, on alcoholic metabolism and alcoholic liver damage. Methods : We evaluated the activities of alcohol dehydrogenase(ADH)and aldehyde dehydrogenase(ALDH), and measured the levels of AST, ALT, glucose, triglyceride, HDL-cholesterol, LDL-cholesterol and phospholipid in serum of guinea pigs. Results and Conclusions : In this experiment, Sungjuchunggan-tang, Pharbitidis Semen and Puerariae Radix significantly suppressed the activity of ADH which is a precursor enzyme of acetaldehyde. Sungjuchunggan-tang and Pharbitidis Semen significantly suppressed the activity of ALDH, which is a catabolic enzyme, and increased its level. Due to alcohol consumption, level of ALT and AST were significantly reduced. These experimental results suggest that Sungjuchunggan-tang and Pharbitidis Semen inhibit the formation of acetaldehyde in the metabolism of alcohol, and affect the recovery of weakened liver functions caused by alcohol.

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.

Membrane-bound alcohol dehydrogenase(ADH) was purified to homogeneity from the acetic acid producing bacteria, Acetobacter sp. KM. The enzyme was solubilized and extracted with Triton X-100 and purified using the Mono-Q ion exchange chromatography and Superose 12 gel filtration chromatography. The enzyme was purified to 12-fold with a yield of 30%. The molecular weight of the purified enzyme was to be 335 KDa. SDS-PAGE of the enzyme showed two subunits with molecular weights of 79 KDa and 49 KDa. It indicated that the enzyme consisted of three subunits of the 79 KDa and two subunits of the 49 KDa. The purified .ADH preferentially oxidized straight chain aliphatic alcohol except methanol. Formaldehyde, acetaldehyde and glutaraldehyde were also oxidized. The apparent Km for ethanol was 1.04 mM and the optimum pH and temperature were 5.0∼6.0 and 32$^{\circ}C$, respectively. V2O5 and divalent cation such as ZnCl2 and NiCl2 inhibited enzymatic activity.

Possibility of Lactobacillus strains able to metabolize ethanol and acetaldehyde in vitro and in vitro was studied. Lactobacillus brevis strains showed higher alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activities than those of other lactic acid bacteria strains. L. brevis HY7401 exhibited the highest ADH and ALDH activities and decreased considerable amounts of ethanol and acetaldehyde in vitro. L. brevis HY7401 cell intake significantly decreased serum ethanol levels in rats fed ethanol (4g/kg BW) compared to control groups. Ethanol level in small intestines of rats fed L. brevis HY7401 was about 50%, and their acetic acid concentration was twofold higher than control. Results reveal L. brevis HY7401, isolated from human, metabolizes ethanol and acetaldehyde in vitro and in vivo.

The objective of this study was to determine the processing conditions for salt dried rockfish Sebastes schlegeli by sun drying and cold-air drying, as measured by alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activity. We processed salt dried rockfish samples. The salinity of rockfish samples was within 1% following salting with 25% salt brine for 3 h. The moisture content of salt dried rockfish was found to reduce linearly from 70.12 to 39.5 g/100 g over the same time interval. The water activities of salt dried rockfish by sun and cold-air drying were 0.94 and 0.87, respectively, after three days of drying. Acid values (AV) were 10.71 and 5.96 mg KOH/g, respectively, after the three day drying period. The ADH activity in a water extract from salt dried rockfish following sun and cold-air drying for 24 h was 228.5% and 226.1% at 13.3 mg/mL, respectively, and was higher than that when drying lasted for 48 and 72 h. The ALDH activity was not affected but both ADH and ALDH activity tended to decrease as the drying time increased from 24 to 72 h. The conditions of processing for the best quality of salt dried rockfish were determined to be drying with a cold-air system for 24 h. These results indicated that water extracts from salt dried rockfish have valuable biological attributes owing to the metabolizing of alcohol and can provide useful information for the design of drying systems for salt dried rockfish.
