Disturbance of antioxidant system is very common in chronic alcoholics and herbal or natural products with antioxidant activity have been used for its treatment. This study was to investigate the effect of Vitis vinifera extract(V), Schisandra chinensis extract(S), Taraxacum officinale extract(T), Gardenia jasminoides extract(G), Angelica acutiloba extract(A) and Paeonia japonica extract(P), and their combinations on the antioxidant and ethanol oxidation system. Male Sprague-Dawley rats were subjected to Lieber-DeCarli ethanol liquid diet(ED) and were then given different herbal extract mixtures for 6 weeks including VST(V 100+S 150+T 150mg/kg/day), VSG(V 100+S 150+G 150mg/kg/day), VTG(V 100+T 150+G 150mg/kg/day), and VAP(V 100+A 150+P 150mg/kg/day). When the activity of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH) were compared between ED only group and herbal extracts treatment group, the differences were statistically significant. Phase I and II(glutathione-S-transferase, phenol sulfatransferase) enzyme activities were found to be significantly higher in the VAT treatment group compared to the ED group. Herbal extracts not only repressed the ethanol-induced elevation of malondialdehyde level, but also protected against ethanol-induced decrease in glutathione content, glutathione reductase, glutathione peroxidase, catalase and superoxide dismutase activities. The administration of the herbal extracts was found to be effective in eliminating lipid-peroxides induced by long-term consumption of alcohol by activating various enzyme systems and physiological active compound formation system. After a chronic consumption of alcohol, Angelica Radix protected the liver via activating the ethanol-metabolism enzyme system, and Paeoniae Radix via activating the ethanol-metabolism enzyme and the phase I, II-metabolism enzyme system. Taraxaci Herba was also effective in liver protection via activating the ethanol-metabolism enzyme system and the phase I, II-metabolism enzyme system, Gardeniae Fructus via activating the phase II-metabolism enzyme system and the anti-oxidation system enzyme, and Schisandra Fructus and a grapestone via activating the anti-oxidation system. Our data suggest that these herbal extracts may be useful as a health functional food or new drug candidate for fatty liver and hepatotoxicity induced by chronic alcohol consumption.

This study was conducted to investigate the detoxification effect of extract from soy-sprout grown using high concentrated oxygen water extract (SE) against alcohol-induced hangover in male Sprague-Dawley (SD) rats. The rats were orally administered with different concentrations of SE beverage [26, 260 and 2,000 mg/kg body weight (b.w.)] and, after 30 min, with alcohol at a dose of 3 g/kg b.w. After 1 and 3 h of alcohol administration, blood was collected from the retro-orbital plexus, while after 5 h, blood was collected from the heart. In the 2,000 mg/kg b.w. SE group, the concentration of blood alcohol was significantly reduced after 1-5 h of alcohol loading as compared with that in the other groups. In addition, the blood acetaldehyde concentration was reduced by SE (2,000 mg/kg b.w.). These results suggest that SE beverage can alleviate alcohol hangover symptoms by stimulating the activities related to hepatic alcohol-metabolizing enzymes.

The antioxidant and alcohol-degrading enzyme activities of soybean sprout sugar solutions (oligosaccharide and sucrose, $50^{\circ}Bx$) were characterized under different soaking conditions. The ratio of sugar solution to sprout content was 25%, 50%, and 75% (w/w), and the soaking times studied were 1, 3, 6, 12, and 24 h. Higher 1,1-diphenyl-2-pycrylhydrazyl (DPPH) radical-scavenging activity was detected in case of the oligosaccharide solution, compared to the sucrose solution. A similar tendency was observed for alcohol-degrading enzyme activity. When the ratio of sugar solution to sprout content was 50% (w/w), the total phenol and flavonoid contents were found to be higher, compared to those observed at 20% (w/w). However, we did not observe a significant difference between 50% and 75% (w/w). Soaking time did not significantly affect the antioxidant and alcohol-degrading enzyme activities of the solutions. As a result, when oligosaccharide solution was used for soaking soy sprouts at a ratio of >50% (w/w), higher antioxidant and alcoholdegrading enzyme activities were observed.

Schisandra chinensis (SC) and Lycium chinense (LC) were widely distributed in Asia and the fruit has been used traditionally for medicinal herbs. The processing method was solid-state fermentation using Aspergillus oryzae for 48 h after stir-frying treatment at $220^{\circ}C$ for 12 min. In this study, in vitro the anti-inflammatory effect and in vivo hangover reduction were compared to unprocessed SC and LC water extract. Anti-inflammatory effects have been evaluated in pro-inflammatory mediators which were secreted by lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Nitric oxide (NO) was determined using Griess reaction. Proinflammatory cytokines such as tumor necrosis factor $(TNF)-{\alpha}$ and interleukin $(IL)-1{\beta}$ were measured by enzyme-linked immunosorbent assays (ELISA). Alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities were compared to processed SC or LC and mixtures thereof (1:1). In vivo study was compared to hangover relief in alcohol-fed mice. After administering a mixture of SC and LC (300 mg/kg) water extract (1:1), mice were fed 3 g/kg of ethanol. Serum was collected at 1, 3, and 5 h intervals to analyze ethanol and acetaldehyde levels using a colorimetric assay kit. The processed SC and LC water extracts compared to raw materials significantly inhibited LPS-induced NO and inflammatory cytokine production in RAW 264.7 cells. The results of the hangover mouse model are also consistent with anti-inflammatory effects. These results suggest that processed SC and LC extracts may be functional materials for the treatment of inflammation and hangover.

This study was carried out to investigate the effect of memory impairment in rats fed alcohol liquid diets. The rats were randomly divided into 4 groups. While the control(C) group received a diet containing 12% of the daily calories with isocarbohydrate, the other groups received a diet containing 12% of the daily total calories with 36% Soju (A), 25% Cynanchi wilfordii radix liquors (WA), and 25% Polygoni multiflori radix liquors (RA) for 6 weeks. After 6 weeks, ADH activity in the brain tissue of the Group A was found to be significantly lower than Group C but significantly higher than both Groups WA and RA(p<0.05). ADLH activity was revealed to be the highest in the Group WA (p<0.05). The concentration of acetaldehyde, a highly toxic metabolite, was the highest in the Group A, but its concentration decreased significantly if fed a liquid diet containing WA. The concentration of acetylcholine, which has a high correlation with memory impairment, was significantly lower in Group A, although Group RA group was the highest compared to the other groups (p<0.05). AChE activity of the Group A was higher than Group C but lower in Groups WA and RA (p<0.05).

This study was designed to investigate the effect of flower of Pueraria lobata on liped peroxidation and activities of alcohol metabolic enzymes in alcohol-treated rats. Male Spra gue-Dawley rats were given 25% ethanol (Alcohol), 25% ethanol and 5 mg tectorigenin/kg B.W.(Alc.-Tec), 25% ethanol and 5mg kaikasaponin III/kg B.W. (Alc-Kai). The contents of serum total lipid, triglyceride and phospholipid were increased by ethanol treatment and were lower in the Alc.-Tec and Alc.-Kai group than in the Alcohol group. Decreased serum HDL-cholesterol by alcohol treatment was recovered by tectorigenin and kaikasaponin III. Microsomal cytochrome P-450, aniline hydroxylase and aminopyrine N-demethylase activities were increased by ethanol and were lower in the Alc. Tec and Alc.-Kai group than in the Alcohol group. Activity of hepatic alcohol dehydrogenase was increased by ethanol and was higher in the Alc.-Tec and Alc.-Kai group than in the Alcohol group. Microsomal ethanol oxidizing system activity was higher in Alc.-Tec group than in the other group. No significant difference was found in catalase activity among treatment groups. These data indicate that tectorigenin and kaikasaponin III were effected alcohol metabolic enzyme system and the liver damage associated with chronic ethanol consumption.

This study was conducted to investigate the eliminatory effect of health drink containing Hovenia dulcis Thunb extract on ethanol-induced hangover in rats. Male Sprague-Dawley rats weighing $200{\pm}10\;g$ were given health drink (10 mL/kg) or other company product(10 mL/kg) 30 min before or after 40% ethanol (5 g/kg body weight) ingestion. To study the effect of health drink on blood ethanol concentration, blood was taken from caudal artery at 1, 3, 5 hr and the animal were sacrificed 24 hr after ethanol ingestion. From 1 to 5 hr, health drink pre- or postdosing significantly decreased the ethanol levels in the blood. The acetaldehyde concentration showed decrement in health drink group and other company product group. The activities of ethanol, alcohol dehydrogenase and aldehyde dehydrogenase measured at postdosing, were also not altered by the administration of health drink. Alanine aminotransferase and aspartate aminotransferase activities showed unaltered resulted in all experimental groups compared with the normal group. These results suggest that oral intake of health drink containing Hovenia dulcis Thunb is effective on elimination of ethanol-induced hangover.
