After pretreatment with ginseng followed by induction of acute intoxication of alcohol, the activities of alcohol dehydrogenase (ADH), microsomal ethanol-oxidizing system (MEOS) and aldehyde dehydrogenase(Ald DH) increased respectively compared to the groups treated with alcohol alone. In case that ginseng was given to rats fed with 5% alcohol instead of water for 60 days, the activities of ADH and MEOS increased compared to the groups treated. On the contrary, the activity of Ald DH in mitochondrial fraction decreased to an extent of about 35% in chronic alcoholism, but after pretreatment of ginseng the activity was restored to the control level. On the other hand, the catalase activity was not significantly affected by either treatment. Ginseng butanol fraction significantly increased the serum isocitrate dehydrogenase activity which is inhibited by alcohol-treated in rat. Alcohol-induced lactate dehydrogenase activity was decreased to control level in liver by ginseng treatment. And the serum level of lactic acid also decreased by ginseng treatment in alcohol-intoxicated rat. Ginseng butanol fraction markedly decreased the xanthine oxidase activity in the ethanol-treated rat liver. It was also observed that ginseng reduced the blood concentration of uric acid on experimentally reduced hyperuricemia by alcohol treatment. Uricase activity was not affected by either treatment. Ginseng butanol fraction decreased the hepatic aniline hydroxylase activity which was induced by alcohol-treated rat. These results suggest that the treatment with ginseng can be promoted the recovery from alcohol intoxication and some therapeutic effect on alcoholinduced metabolic disease.

Allyl alcohol is metabolized in the liver through two steps, first to reactive acrolein by alcohol dehydrogenase (ADH), subsequently to acrylic acid by aldehyde dehydrogenase (ALDH). Since ethanol could compete the same enzymes to be metabolized in the liver, we have determined the plasma concentrations of allyl alcohol and ethanol followed by combined treatment. Pretreatment of rats with 2g/kg ethanol followed by ip administration of 40mg/kg allyl alcohol increased the lethality significantly. Determination of in vivo blood concentrations revealed that ethanol pretreatment caused the apparent decrease in allyl alcohol clearance, whereas acetaldehyde level in blood increased significantly by allyl alcohol treatment, as determined by head space GC analysis. Treatment of 4-methylpyrazole, an inhibitor of ADH, delayed allyl alcohol elimination significantly and reduced its lethality. Collectively, these findings suggested that reduction of allyl alcohol clearance in the presence oj ethanol was mediated through ADH competitive inhibition.

Objectives : This study was performed to review the research trends in treatment for acute alcohol intoxication in traditional Chinese medicine. Methods : 19 studies were selected by searching CNKI(China National Knowledge Infrastructure) from 2006 to 2011, and we performed a systemic review of them. Results : All studies are controlled clinical trials using pharmacopuncture therapy. Each experimental group was given various kinds of pharmacopuncture therapy, whereas each control group was given another western medicine or treatment. Emergent treatment was used in both groups. The results of 15 studies showed that pharmacopuncture therapy has an effect on the treatment of acute alcohol intoxication. However the quality of these clinical trials wasn't high. Conclusions : It seems that the researches for acute alcohol intoxication have been performed actively in traditional Chinese medicine. We hope that our study can activate clinical research for this disorder in Korean traditional medicine.

To evaluate the effect of cyclohexane(CH) treatment on the liver cytochrome P-450 dependent aniline hydroxylase(CYPdAH) activity in alcohol-pretreated animals, CH(1.56 g/kg body weight) was intraperitoneally administered to Sprague-Dawley male rats, which had been drunk 15％ alcohol in distilled water for 1,3 and 6 weeks. CH was injected to rats 4 times every other day and the animals were sacrificed at 24 hours after injection of CH. In the alcohol-pretreated rats, liver injuries were not demonstrated on the basis of the liver weight per body weight, the levels of serum alanine aminotransferase and hepatic microsomal glucose-6-phosphatase activities. By the CH treatment, alcohol-pretreated animals showed the significantly increased activity of hepatic microsomal CYPdAH. Concomitantly $V_{max}$ value in CYPdAH was more increased, whereas $K_{M}$ value more decreased in alcohol-pretreated animals by the treatment of CH. In conclusion, the increasing cause of microsomal CYPdAH in CH-treated rats pretreated with alcohol may be due to induction of enzyme protein in rat liver.r.r.

This study was carried out for the purpose of improving the persimmon vinegar. Crushed persimmon(persimmon pulp) was used at alcohol fermentation using Saccharomyces bayanus for persimmon alcohol medium preparation. Glucose(8.39%) and fructose(7.96%) were the dominant free sugar in persimmon pulp before the at cohol fermentation. They decreased abruptly during alcohol fermentation and glucose was consumed more rapidly than fructose. Final alcohol concentration was finally reached to 8%(v/v) in 5 days for mentation of persimmon pulp. Pectinase pre-treatment of persimmon pulp resulted in tusker contents of galacturonic acid, galactose, methyl alcohol and isoamyl alcohol in main mash for alcohol fermentation than those in main mash prepared without pectinase pre-treatment. After alcohol fermentation tannin concentration was 350ppm and astringency was not perceived.

The effects of drying agents and ethyl alcohol treatment on the flower color of Gentiana uchiyamai. The flower color was not much changed in flower sheet, in the case of absorbtion papers only. The color was least changed in Korean and China hwasunjis, in the case of absorbtion papers and silica gel treatment. The color was less changed in flower sheets, window papers, and China hwasunjis, and was most changed in newspapers, in the case of absorbtion papers and Na$_2$SO$_4$ treatment. The color was least changed in China hwasunjis, and most changed in dampened papers, in the case of absorbtion papers and CaO treatment. The color tended to change far from the original one, as treatment time got longer, in the case of 0.01M and 0.lM of tartaric acid. The longer the treatment time and the bigger the concentration of ethyl alcohol, the bigger flower color.

The effect of treatment with pine needle oil upon rat hepatocytes exposed to alcohol was investigated. The body weight gain, ratio of liver and kidney to body weight, and serum biochemistry of rats administered both alcohol and pine needle oil were compared to control rats treated with alcohol alone. Normal untreated control rats, negative control rats with ethanol treatment, positive control rats with both alcohol and the commercially available hangover cure solution (HCS) treatment and the test group with both alcohol and pine needle oil treatment exhibited aspartate aminotransferase (AST) levels of $84.43{\pm}47.88\;U/L$, $254.57{\pm}463.20\;U/L$, $70.29{\pm}12.60\;U/L$ and $67.00{\pm}5.06\;U/L$, respectively, and cholesterol levels of $95.71{\pm}6.86\;mg/dl$, $113.80{\pm}38.19\;mg/dl$, $91.57{\pm}6.30\;mg/dl$ and $82.29{\pm}4.98\;mg/dl$, respectively. Alanine aminotransferase (ALT) levels were $44.00{\pm}9.04\;U/L$ in normal untreated control rats, increased to $215.43{\pm}428.93\;U/L$ with the administration of ethanol, but interestingly were significantly reduced to $37.83{\pm}6.57\;U/L$ in the test group (p<0.05). Triglyceride (TG) levels were $39.57{\pm}8.62\;mg/dl$ in normal untreated rats, increased to $73.71{\pm}61.20\;mg/dl$ in rats administered alcohol, but were reduced to $26.14{\pm}4.82\;mg/dl$ in the test group (p<0.0l). The pine needle oil treatment significantly reduced the levels of AST, ALT and TG compared to the control rats. These results indicate that pine needle oil can positively mediate the effects of alcohol on hepatocytes and general liver functions.

Purpose: This study was conducted to investigate the effect of freeze-dried Gastrodiae rhizoma powder (GR) on the liver function and alcohol metabolism in alcohol treated rats. Methods: The rats were administered various concentrations of GR (100 mg, 200 mg, 300 mg/kg B.W.) for 3 days 1 hour before 50% (v/v) ethanol (3 g/kg B.W.) administration. Two tests focusing on liver function and alcohol metabolism in acute alcohol treatment were carried out. Results: Glutamic oxaloacetic transaminase activity was significantly increased by alcohol treatment, and was decreased by 100 mg GR administration. Acute ethanol treatment led to significant increase in alcohol and acetaldehyde levels of serum and liver. However, 100 mg GR administration led to a significant reduction in increased alcohol level in the serum with decreased alcohol dehydrogenase (ADH) activity and increased acetaldehyde level in liver was significantly reduced by three levels. Conclusion: These results suggest that GR can be effective in enhancing liver function and alcohol metabolism in the alcohol-treated rats. Studies on the appropriate dosage of GR should further be developed to treat alcohol detoxification and stimulate liver function.

Objectives : The effect of pear extract with Daekumeumjagami and vitamin C medication(PDV) on alcohol metabolism and hepatic injury was assessed following hepatic injury induced by alcohol in mice. Methods : The model of alcoholic hepatic injury was established by orally administration with 3 g/kg 25% alcohol in mice. PDV was orally administrated once a day for 5 days. Mice were randomly divided into 5 groups : normal group, control group, and PDV groups (PDV-A, PDV-B and PDV-C). The activities of aspartate amino transferase (AST) and alanine amino transferase (ALT) and alcohol dehydrogenase (ADH) in serum, superoxide dismutase (SOD) and catalase in liver were determined after alcohol exposure. Results : Compared with control group, treatment with PDV-B and PDV-C significantly elevated activities of ADH. Moreover, the index of hepatic injury in serum was significantly decreased by treatment with PDV-B and PDV-C in ALT activity and PDV-C in AST activity. Additionally, enhanced catalase activities in liver was found in PDV-C treated mice after exposure to alcohol. Also, WBC in blood was significantly lower by treatment with PDV-B and PDV-C. Conclusions : This study suggests that PDV treatment could enhance alcohol metabolism, and prevent hepatic injury after alcoholic hepatic injury and that this effect is likely related to its modulation on the alcohol metabolizing and antioxidant enzymes.

This study investigated the effect of the addition of alcohol on the quality change of Chungkukjang during the aging, The Cung-kuk-jang was made by the degree of 3, 5, 10%, respectively, and determined NH2-N, NH3-N, total acidity, cell numbers, lactate, succinate and phenolic acid to measure the change of flavor component in the aging of 2$0^{\circ}C$. 1. In the treatment groups of different amount of alcohol and salt added and aging period of Chung-kuk-hang, NH2-N was more decreased with more addition of alcohol and salt in the 3-and 10-day of aging. NH3-N was increased gradually in the addition of up to 2.0% alcohol and then decreased in the 3-and 10-day of aging. 2. In the treatment groups of different amount of alcohol added and aging period Chung-kuk-hang, the total acidity was more decreased with more addition of alcohol and higher degree of salt. Cell number was decreased rapidly with the addition of 1.0% alcohol in the 3-day and then decreased relatively and in the 10-day of aging, and it was increased with the addition of alcohol 3. With the addition of alcohol and the different growing temperature, the content of phenolic acid was more browning changed at 3$0^{\circ}C$ than that of at 2$0^{\circ}C$ and the phenol content of each group was decreased with increasing the addition amount of alcohol. Thus, the more addition of alcohol amount would the more extend the period of Chung-kuk-hang aging.
