This study is purposed to check up the natural 12 kinds of herbal extracts suitable for hangover and based on the results of contents of phenolic compounds, ABTS radical scavenging activity, alcohol dehydrogenase (ADH), and acetaldehyde dehydrogenase (ALDH). Selected 8 kinds of herbal extracts are blended according to the efficacy and the pearson's correlation between each content and activity. C. sinensis var. sinensis, P. densiflora Gnarl and P. lobata Ohwi showed excellent ADH activity, P. lobata Ohwi had a strong correlation between the content and efficacy, and C. sinensis var. sinensis, P. densiflora Gnarl had a negative correlation. Through the ADH and ALDH activity test of F.1 to F.7, the F.7 showed the highest synergic effect and selected as an optimal formulation. F.7 intake-group, the breath alcohol concentration was significantly reduced to 58% after 30 minutes and 27% after 120 minutes, compared to right after alcohol consumption. After alcohol consumption, there was a significant improvement effect (p<0.05) in tired and thirst in the intake group compared to the non-intake group.

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 effect of Paecilomyces tenuipes water extract (PTWE) on the alcohol metabolism was examined on rats. PTWE of 0, 30, 100 mg/kg body weight was administrated orally to the rats 30 min before oral treatment of 3 g/kg body weight of alcohol. Blood alcohol and acetaldehyde concentrations were measured 0.5, 1, 3, 6, 9 hr after alcohol treatment. Hepatic alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ADH), microsomal ethanol oxidizing system (MEOS) activities were measured 9 hr after alcohol treatment. There were no differences in blood alcohol concentrations and area under the curve (AUC) of alcohol. PTWE decreased acetaldehyde concentration and there were significant differences after 6 hr in 30 mg/kg PTWE and after 3 and 9 hr in 100 mg/kg PTWE, respectively. In particular, 100 mg/kg PTWE decreased AUC of acetaldehyde by 44%. However, there were no changes in the hepatic ADH, ALDH, and MEOS activities.

White breads containing Korean blue mussel (Mytilus edulis) powder were prepared and characterized. WB (white bread without blue mussel) and four different MBs (white breads containing blue mussel; number in front of MB means added % of blue mussel powder per wheat flour) were prepared by the straight dough method. With addition of blue mussel to bread, lightness decreased, whereas redness and yellowness increased. Addition of blue mussel did not significantly affect specific volumes of breads. DPPH and ABTS radical scavenging activities significantly increased with increasing blue mussel content. Addition of blue mussel to breads also increased alcohol dehydrogenase and acetaldehyde dehydrogenase activities. In the sensory test, 1MB acquired relatively high points for taste, flavor, texture, and preference. The results indicate that blue mussel can be applied to white bread to improve physiological functions without reduction of physicochemical characteristics.

Excessive alcohol consumption causes various degenerative brain diseases including Alzheimer's disease and Parkinson's disease. Absorbed ethanol is metabolized to acetaldehyde and acetic acid by alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). Acetaldehyde is well known as a toxicant through generation of reactive oxygen species (ROS). Therefore, ALDH2 activity may play important roles in the pathogenesis of alcohol-induced brain diseases. In this study, we demonstrated the effects of ALDH2 enzyme activity on lipid peroxidation in brain tissues and urine of mice exposed to ethanol for 8 weeks. Five male, 8-week old Aldh2 (+/+) and Aldh2 (-/-) mice (C57BL/6J strain) in each group were exposed to ethanol for 8 weeks (2 g/kg wt./day) using gavage, and those in the control group received 0.9% saline alone. Thiobarbituric acid reactive substances (TBARS) level, a marker for lipid peroxidation, was measured in whole brain tissue and urine by high performance liquid chromatography. As a result, chronic ethanol treatment did not show any statistical change on the TBARS level of brain tissue in both Aldh2 (+/+) mice and in Aldh2 (-/-) mice. However, following ethanol exposure for 8 weeks in Aldh2 (-/-) mice, the urinary TBARS levels were significantly increased to more than double compared to the pretreatment group. This result was not observed in Aldh2 (+/+) mice. These results suggest that although ALDH2 enzyme activity plays a role in the generation of ROS in the whole body, it does not seem to be important in the pathogenesis of alcohol induced degenerative brain diseases.

To identify normal levels of ethanol, acetaldehyde and alcohol dehydrogenase(ADH) activity in blood of Koreans, ethanol and acetaldehyde levels, activity of ADH in blood of Koreans, ethanol and acetaldehyde levels, activity of ADH in blood were measured in 97 subjects(male : 36, female : 61), 45 subjects(male : 21, female : 24) were not exposed to organic solvents and any other chemicals. Fifty two subjects(male : 15, female : 37) were exposed to organic solvents including toluene and xylene. The results were summerized as follows : 1. The blood ADH was not detected in exposed and non-exposed group. 2. The average blood ethanol level of non-exposed group was 0.0490 mg/dl, and exposed group was 0.0363 mg/dl. They were statistically significant(p<0.05). 3. The blood acetaldehyde levels in exposed group were significantly higher than that of non-exposed group was not statistically significant (p>0.05). 4. The average blood ethanol level of males in both groups was significantly higher than that of females, however, they were not statistically significant (p>0.05).

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.
