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.

This study was conducted to investigate the effect of Pepino extract on alcohol metabolism in male Sprague-Dawley rats. When the rats were given Pepino extract 30 min before 60% alcohol (4 g/kg B.W) administration, alcohol concentration in blood was significantly reduced, but acetaldehyde concentration was not significantly different, compared with the control group after 3 hrs of alcohol administration. When the rats were given Pepino extract ($1^{\circ},\;5^{\circ},\;10^{\circ},\;&\;15^{\circ}$ Brix) 30 min before 60% alcohol administration, alcohol concentration in blood with $1^{\circ}$ Brix Pepino extract was 44% after 3 hrs of alcohol administration, compared with the control group. When the rats were given with $1^{\circ}$ Brix Pepino extract at 30 min before 60% alcohol administration, alcohol concentration in blood was significantly reduced after one hour and acetaldehyde concentration was reduced by 19% after 5 hrs of alcohol administration, compared with the control group. Glutamate-oxaloacetate transaminase and glutamate-pyruvate transaminase activities were not significantly different in all experimental groups, compared with the control group. These results suggest that Pepino extract can be effective in alcohol metabolism in the alcohol-treated rats.

The purpose of present study was to investigate the protective effect of silkworm excrement powder (SEP) on alcohol-induced hepatotoxicity in rats. Semisynthetic diet supplemented with SEP (3%, w/w) given to alcohol-feeding rats for 30 days, then blood and tissues were collected, processed and used for alcohol concentration mensuration, various biochemical estimations and histopathological examination. Chronic alcohol administration resulted in significantly increase in the activities of the clinically important liver marker enzymes, alanine aminotransferase (ALT), aspartate aminotransferase (AST), $\gamma$-glutamyl transpeptidase ($\gamma$-GTP) and lactate dehydrogenase (LDH). Also, a highly significant increase in the blood alcohol level by alcohol treatment was observed. But alcohol-induced elevation of ALT and LDH levels markedly prevented and the level of blood alcohol decreased in SEP treated rats as compared to alcohol-administered control rats. SEP supplementation showed highly decreased the concentrations of total lipid, triglyceride and cholesterol in serum, as compared with alcohol treated control rats. Alcohol treatment induced the marked accumulation of large lipid droplets, hepatocytes necrosis and inflammation in the liver, but SEP administration attenuated to alcohol-induced accumulation of lipid droplets and hepatocyte necrosis. The results indicated that SEP may exert a protective effect against alcoholic hepatotoxicity through decreasing the activity of hepatic marker enzymes.

This study investigated the effect of improved liver function in rats administered with ethanol by kimchi lactic acid bacteria with high GABA producing capacity. Sprague-Dawley male rats were divided into four groups; normal diet control (NC), ethanol control (EC), ethanol＋Lactobacillus sp. OPK2-59 normal powder (EL1), ethanol＋Lactobacillus sp. OPK2-59 GABA powder (EL2) and fed for 6 weeks. Analysis showed that there were no significant differences in body weight and feed consumption among the groups during the experimental period. Also, there were no significant differences in organ weight among the groups. The test results showed total cholesterol and triglyceride in the blood concentration that were increased by ethanol administration were significantly lowered in EL2 group. Liver triglyceride was also significantly lowered in the EL2 group compared with the EC group. Serum GOT and GPT, and liver GOT levels were significantly lower in the EL2 group compared with the EC group. Serum ethanol concentration was lower in the EL1 and EL2 groups compared with the EC group. SOD activities in liver were significantly increased in the EL1 and EL2 groups compared with the EC group. These results suggest that Lactobacillus sp. OPK2-59 GABA powder improves lipid and enzyme profiles of rats administered with ethanol.

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 effects of Monascus-fermented Korean red ginseng (MFRG) on the contents of serum lipids and tissues lipid peroxidation was investigated in alcohol feeding rats (AC group). Serum contents of total lipid and free fatty acid in alcohol feeding rats were significantly increased, but these increases tended to decrease in the AMFRG group. Serum triglyceride content was also significantly decreased in the AMFRG group compared to other groups. Serum content of total-cholesterol was significantly increased in AC group compared to normal control (NC) group, whereas there was no significant difference between the AC and AMFRG groups. Content of HDL-cholesterol in serum was slightly increased in the AC group compared to the NC group, but this increase in the AC group was more significantly increased in the AMFRG group. At the same time, atherogenic index (AI) was also significantly decreased in the AMFRG group compared to the AC group. Contents of thiobarbituric acid reactive substances (TBARS) in the liver, heart, spleen and testes were significantly increased in the AC group compared to the NC group, but these increases were significantly less in the AMFRG group. Contents of liver nonheme ion was increased in the AC group and was significantly decreased in the AMFRG group, which suggested that lipid peroxidation contents are inversely correlated with liver nonheme ion content. Hepatic glutathione concentration was significantly decreased in the AC group, but this content was significantly increased in the AMFRG group and it showed the antioxidant abilities of glutathione. These results suggested that Monascus-fermented Korea red ginseng has anti-atherogenic index (AI) effects as well as antioxidative activities through reduced tissue oxidative stress in alcohol feeding rats.

We investigated whether or not Schisandra chinensis (SC), a traditional herbal medicine, has protective effects against alcohol-induced fatty liver and blood alcohol clearance. Two tests focused on acute intoxication and chronic ethanol treatment were carried out. For the chronic ethanol treatment test, rats were fed ethanol by intragastric administration everyday for 8 weeks to induce alcoholic fatty liver. Ethanol treatment significantly increased blood alcohol concentration at 90 min after acute ethanol intoxication. Compared with the two ethanol-treated groups, rats administered ethanol along with SC extracts showed an approximately 13% increased blood alcohol clearance rate at 360 min. Chronic ethanol treatment significantly increased serum and hepatic triglyceride (TG) levels, and caused fatty degeneration of liver. Ethanol treatment also elevated the serum total-cholesterol (TC) level. However, after feeding of ethanol plus SC extracts, ethanol-induced elevation of hepatic TG levels reversed, whereas elevation of serum TG and TC levels was not observed after treatment with SC extracts. Ethanol treatment significantly increased ${\gamma}$-GT, aspartate aminotransferase, and alanine aminotransferase activities after 8 weeks. Compared with the ethanol-fed group, rats administered ethanol plus SC extracts for 4 weeks showed attenuated fatty degeneration as well as decreased hepatic function test values. SC administration also significantly increased intracellular lipid accumulation in hepatocytes and reduced steatosis score and hepatic TG levels, as measured by biochemical and histolopathological analyses. Our results indicate that the protective effects of SC are accompanied by a significant decrease in hepatic TG levels, thereby suggesting SC has the ability to prevent ethanol-induced fatty liver, by reducing hepatic TG and enzyme levels in alcoholic rats.
