Objective : This dissertation was designed to evaluate the effect of BCL(refinded Bambusae Caulis in Liqua-men) oral administration and herbal acupuncture on alcohol metabolism and liver function. Methods : Mice were damaged by a large quantity of alcohol and received treatment of either BCL $1mg/kg$ in oral or BCL $250{\mu}g/kg$ in herbal acupuncture-BL18 BL19 bilateral. and then such parameters as GOT, GPT, catalase and superoxide dismustase(CuZn-SOD, Mn-SOD) were measured. Results : 1. Compared with control group, the activity of GOT, GPT in serum was significantly reduced and the proper degree of alcohol in serum was not significantly differ from oral administration group and herbal acupuncture group. 2. The activity of catalase in liver cell tissue and the activity of CuZn-SOD in liver cell tissue, compared with control group, was not sigificantly affected either by oral administration and herbal acupuncture group. But the activity of Mn-SOD was significantly increased in oral administration group, while it was not the case in acupuncture group. Conclusion : we consider that BCL oral administration and herbal acupuncture is highly effective in recovering alcohol metabolism and liver disfunction induced by alcohol.

To consider potentially new sources which have hypoglycemic effect and accelerating alcohol detoxification, this study was designed to investigate the effect of Crataegus fructus and Morns alba L. in alcohol-treated rats. I compared the body weight, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alcohol dehydrogenase (ADH), and aldehyde dehydrogenase (ALDH) of rats administered both alcohol and extract of experimental plants to rats treated with alcohol alone. Administration of extracts of C. fructus and M alba, respectively, resulted in a significant reduction in the blood glucose level and the activities of ADH of liver compared to the control rats, and administration of extract of M. alba showed significantly lower on bodyweight gain in the rats than in other treated rats. In contrast, the activities of ALDH of liver were increased. The activities of AST and ALT between the only alcohol-treated rats and the alcohol and experimental plants-treated rats were no significant difference. The results suggest that C. fructus and M alba have a hypoglycemic effect, and reduce liver damage by accelerating acetaldehyde metabolism in alcoholic rats, so the combined effect of C. fructus and M alba may be considered as an alternative remedy for hangovers, alcohol-induced overweight and alcohol-induced diabetes.

The possible protective effects of highly zinc-containing yeast Saccharomyces cerevisiae, FF-10 strain, isolated from tropical fruit rambutan on acute alcoholic liver injury in rats were evaluated. Zinc concentration in this strain was 30.6mg%. The activities of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and $\gamma$-glutamyl transpeptidase ($\gamma$-GTP) were highly increased when alcohol was treated, relative to the normal rats. Also, a highly significant increase in the blood alcohol and acetaldehyde levels by alcohol treatment was observed. Administration of FF-10 strain markedly prevented alcohol-induced elevation of the activities of serum ALT, AST, and $\gamma$-GTP, and the levels of blood alcohol and acetaldehyde, and these reduced levels reached to that of normal rats. As compared with alcohol treated control rats, the FF-10 strain supplementation showed highly decreased the triglyceride concentration in serum. Alcohol treatment induced the marked accumulation of small lipid droplets, hepatocytes necrosis, and inflammation, but FF-10 strain administration attenuated to alcohol-induced accumulation of small lipid droplets and hepatocyte necrosis in the liver. Therefore, the current finding suggests that zinc-enriched yeast FF-10 strain isolated from tropical fruit rambutan may have protective effect against alcohol-induced hepatotoxicity.

Alcohol intake is known to affect various organs in the human body, causing reduction of salivation in the oral cavity. Hypo-salivation effect of alcohol is a common feature, but the mechanism in salivary glands is still poorly studied. Therefore, in this study, the changes in salivary secretion and water channel protein (aquaporin5, AQP5) in salivary glands of mice were investigated after ethanol administration. Animals were divided in to 4 groups with the control, 4 g/kg ethanol, 8 g/kg ethanol and 16 g/kg ethanol administration groups. One hour after ethanol administration, saliva was collected from the oral cavity, and the animals were killed and parotid and submandibular glands were extracted to analyze the histopathology, AQP5 immunihistochemistry and AQP5 protein level. According to the results, the salivation rate decreased irrespective of the ethanol dose in mice, and viscosities increased with increase in ethanol dose. However, there were no pathological changes in parotid and submandibular glands due to ethanol administration. Expression of AQP5 in parotid and submandibular glands decreased with increase ethanol administration These results indicate that the reduction of salivary secretion due to acute alcohol intake is closely related to decrease of the water channel protein such as AQP5 in parotid glands and submandibular glands, rather than the damage of salivary glands.

BACKGROUND/OBJECTIVES: Excessive alcohol consumption has harmful health effects, including alcohol hangovers and alcohol-related liver disease. Therefore, methods to accelerate the alcohol metabolism are needed. Laurus nobilis is a spice, flavoring agent, and traditional herbal medicine against various diseases. This study examined whether the standardized aqueous extract of L. nobilis leaves (LN) accelerates the alcohol metabolism and protects against liver damage in single-ethanol binge Sprague-Dawley (SD) rats. MATERIALS/METHODS: LN was administered orally to SD rats 1 h before ethanol administration (3 g/kg body weight [BW]) at 100 and 300 mg/kg BW. Blood samples were collected 0.5, 1, 2, and 4 h after ethanol administration. The livers were excised 1 h after ethanol administration to determine the hepatic enzyme activity. The alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH), superoxide dismutase (SOD), and glutathione peroxidase (GPx) activities in the liver tissue were measured. RESULTS: LN decreased the serum ethanol and acetaldehyde levels in ethanol-administered rats. LN increased the hepatic ADH and ALDH activities but decreased the alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase activities in the ethanol-administered rats. In addition, LN inhibited lipid peroxidation and increased the activities of SOD and GPx. CONCLUSIONS: LN modulates the mediators of various etiological effects of excessive alcohol consumption and enhances the alcohol metabolism and antioxidant activity, making it a potential candidate for hangover treatments.

These studies were conducted to investigate the effects an herbal extract composition(MHE) containing $Hovenia$ $dulcis$ T., $Artemisa$ $capillaris$ T., $Pueraria$ $thunbergiana$ B., $Polygonatum$ $falcatum$ A., $Agastache$ $rugosa$ O., $Silybum$ $marianum$ L. and $Glycyrrhiza$ $uralensis$ F. in alcohol administered mice. Prophylactic administration of different doses of MHE(20~100 mg/kg) had beneficial actions toward alcohol degradation in acute alcohol treated mice. In addition, intraperitoneal administration of the MHE showed anti-inflammatory effects in inhibition tests of vascular permeability produced by acetic acid. MHE also reduced the concentrations of nitric oxide(NO) and tumor necrosis factor(TNF)-${\alpha}$ in macrophages that were activated by LPS. These results demonstrate that MHE possesses the potential to stimulate alcohol degradation and inhibit inflammatory effects in mice.

Alcohol is a major risk factor for several diseases and especially excessive, long-term alcohol consumption are caues the damage of immunity such as the inhibiton of secretion of lymphokine and proliferation of immune component cell. This study observed that the inhibition of T lymphocytic differentiation and secretion of interleukin 2(IL-2) induced in thymus of ICR mouse by chronic alcohol administration. After 8% alcohol voluntary administered for 120 days, the thymic tissue immunohistochemically stained by following ABC method that used monoclonal antibody including L3T4(CD4), Ly-2(CD8), and IL-2 receptor(CD25R) after embedding with paraffin. The results were as follows. 1. The size of thymic medulla in test group reduced than control group. 2. The number of helper T lymphocyte, cytotoxic T lymphocyte, and IL-2 receptor were decreased in thymic medulla and cortico-medullary junction of test group and the degree of CD4, CD8, and CD25R positive reaction were soften in test group. These results indicated that the secretion of IL-2 in thymus was inhibited by chronic alcohol administration and subsequently prevent to differentiate from thymocytes to T lymphocytes. As this view, cell mediated immunity were reduced by chronic alcohol administration.

Increased alcohol consumption is a burden on the world because it is associated with various health problems. However, the effects of silkworms on alcohol metabolism have not been studied yet. The hard-to-eat mature silkworms have become easier to ingest recently due to the development of technology, steam-lyophilising mature silkworm larvae. In this study, we investigated and compared the effects of SMSPs from three silkworm varieties, Baekokjam, Golden-silk and Yeonnokjam weaving white, golden, and light green cocoons on alcohol metabolism in vivo. Sprague-Dawley rats pretreated with three SMSPs (0.1 g/kg or 1 g/kg body weight) or normal diet (AIN-76A) for 2 weeks were subjected to intragastric administration of absolute ethanol (3 g/kg body weight, 3 h). Three SMSPs did not affect the final body weight and liver weight. All 3 SMSPs were effective to reduce the enzymes in alcohol metabolism, alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), and liver damage and enzymes involved in liver damage, aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Among SMSP from 3 varieties of silkworm, preadministration of 1 g/kg Baekokjam SMSP showed the most effective suppressive effect on the activities of ADH, ALDH, AST and ALT. The Baekokjam SMSP contained higher amounts of beneficial amino acids than Golden-silk or Yeonnokjam SMSP. These results suggest that Baekokjam SMSP might be used as a new and promising candidate for improving alcohol metabolism and liver injury through promoting rapid alcohol metabolism.

The purposes of this studies were to investigate the effect of dietry Se levels and alcohol administration on the lipid hyperoxidation and the lipid metabolism in the rat. Seventy two male rats of Sprague-Dawley Strain weighting about 58~629 were divided into 12groups. The dietary Se levels were 10, 0.4 and Omg, and the dietary a-tocopherol levels were 150 and 0mg per kg diet, respectively. Alcohol-administrated groups received drinking water solution containing 10% of ethanol from the 3-weeks of experimental periods. The obtained experimental results are summarized as follows. 1. Food intake, body weight gain and food efficiency ratio were significantly lower in H-, L-and alcohol administrated groups(-A) by administrated Se and alcohol in diet. The weight of liver and spleen tended to be greater in H- and alcohol administrated groups. 2. The glutathione values in liver tend to be lower in alcohol or Vit. E administrated groups than nonadministrated groups. Also there were higher in H- and L- than C-groups, but the increasing range decreased due to administrated alcohol. The lipid peroxide values In liver were significantly higher in alcohol groups, and L- and tocopherol groups were higher values. Specially the increasing of lipid peroxide values were significantly effected by alcohol in low Se and Vit. E groups. 3. The contents of total glyceride in plasma were higher in alcohol groups, there were significantly higher values in alcohol administrated groups under low Se and Vit. E groups. The contents of total cholesterol and HDL-cholesterol In plasma were significantly higher in alcohol groups. 4. The contents of total lipid in liver were higher alcohol groups, and slightly higher values in low Se groups(L-groups) than other groups, also higher values in low Vit. E groups. Those of total glyceride in liver were significantly higher in alcohol groups, appeared highest values when alcohol was administrated in low Se and Vit. E groups. The increasing of total glyceride content was significantly effected by alcohol in low Se groups than that in C-groups.

Excessive alcohol consumption can have serious negative consequences on health, including addiction, liver damage, and other long-term effects. The causes of hangovers include dehydration, alcohol and alcohol metabolite toxicity, and nutrient deficiency due to absorption disorders. Additionally, alcohol consumption can slow reaction times, making it more difficult to rapidly respond to situations that require quick thinking. Exposure to a large amount of ethanol can also negatively affect a person's righting reflex and balance. In this study, we evaluated the potential of lactic acid bacteria (LAB) to alleviate alcohol-induced effects and behavioral responses. Two LAB strains isolated from kimchi, Levilactobacillus brevis WiKim0168 and Leuconostoc mesenteroides WiKim0172, were selected for their ethanol tolerance and potential to alleviate hangover symptoms. Enzyme activity assays for alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) were then conducted to evaluate the role of these bacteria in alcohol metabolism. Through in vitro and in vivo studies, these strains were assessed for their ability to reduce blood alcohol concentrations and protect against alcohol-induced liver damage. The results indicated that these LAB strains possess significant ethanol tolerance and elevate ADH and ALDH activities. LAB administration remarkably reduced blood alcohol levels in rats after excessive alcohol consumption. Moreover, the LAB strains showed hepatoprotective effects and enhanced behavioral outcomes, highlighting their potential as probiotics for counteracting the adverse effects of alcohol consumption. These findings support the development of functional foods incorporating LAB strains that can mediate behavioral improvements following alcohol intake.
