This paper investigates the association of among alcohol consumption and blood vitamin D and lead concentrations. Subjects to 4,074 with adults over the age of 20 in the 5th Korea National Health and Nutrition Examination Survey, correlation analysis is used to validate the relations between an average daily alcohol consumption and blood vitamin D and lead concentration, and to study the effects of blood vitamin D to the lead concentration is carried out regression analysis. The correlation analysis shows that alcohol consumption has the correlation with blood vitamin D and lead concentration(p<0.01). As the results of regression analysis, age(p<0.01), education(p<0.01), occupation(p<0.05), alcohol consumption(p<0.01), vitamin D(p<0.05) appear significant influence on lead concentration in male. Alcohol consumption increases not only lead concentration but also vitamin D. Blood vitamin D also contributes to the rise in lead concentration, but in the reverse the metabolic activity of blood vitamin D by influence of lead receives a negative effect in our body.

In this study, we investigated the antioxidant activities, alcohol metabolizing activities, nitrite scavenging ability, angiotensin converting enzyme (ACE), and elastase inhibitory effects of hot water extract from Makgeoly (HWM). Antioxidant activities were measured by using 2,2.diphenyl.1.picryl.hydrazyl (DPPH) free radical scavenging activity and SOD (superoxide dismutase).like activity. The DPPH radical scavenging activity and SOD.like activity of HWM were remarkably increased in a dose.dependent manner and were 48.0% and 98.7% at 10 mg/ml, respectively. To determine the influence of HWM on alcohol metabolizing activity, the generating activities of reduced.nicotinamide adenine dinucleotide (NADH) by alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) were measured. The facilitating rates of ADH and ALDH activity by HWM were remarkably increased in a dose.dependent manner and were 70.2% and 64.1% at 10 mg/ml, respectively. The inhibitory activity against angiotensin converting enzyme (ACE) of HWM was increased in a dose.dependent manner and was 74.2% at 10 mg/ml. The nitrite scavenging ability of HWM showed the most remarkable effect at pH 1.2 and 2 mg/ml. These results indicated that HWM may have valuable biological properties owing to their antioxidant activities, ADH and ALDH activity, nitrite scavenging ability, and ACE inhibitory activity.

The purpose of this study was to investigate the effects of ingestion of rabies and ginseng fruit extracts on alcohol hangover, liver damage protection, fatigue recovery, and physical strength improvement. A total of 64 volunteers aged over 20 were participated in this study and the randomized and repeated measures design method was used to divide a group of participants with a random assignment. All participants were divided into 4 groups (n=16) treated with hoveni dulcis thunb extract + ginseng berry extract (ARI 1000), hoveni dulcis thunb extract, ginseng berry extract, and placebo. As a result of respiratory alcohol concentration change, the group treated with ARI 1000 was significantly lower than the group treated with hoveni dulcis thunb extract, ginseng berry extract, and placebo in 1 hour of drinking, and significantly lower than the placebo group in 2 hours and 3 hours of drinking (p<0.05). After 2 and 3 hours of alcohol consumption, blood alcohol concentration of the group treated with rabies ARI 1000 was significantly lower than those of the other 3 groups (p <0.05). In conclusion, ingestion of ARI 1000 before drinking may significantly reduce the respiratory and blood alcohol concentrations, which may induce an effect on the hangover effect.

Effect of combined preparation (DWP715) containing Alaska pollack extract, maltol, ascorbic acid and nicotinamide on decreasing of blood alcohol was evaluated in human blood. Treatment of DWP715 prior to administration of 25% alcohol (100 mL) decreased alcohol concentration in blood and showed significant difference after 2 hours. The pharmacokinetic parameters such as area under the concentration-time curve (AUC), $C_{max},\;T_{max}\;and\;T_{1/2}$ were also decreased and delayed when compared with control values. Effects of DWP715 on anti-fatigue and anti-oxidation activities were also studied in the restraint stress model using various parameters (GOT, GPT, LDH values and organ weights) on mild condition and examined through the content of lipid peroxide induced by 2% $CCl_4$ in mouse livers. While GPT level, thymus and adrenal weight were not influenced by DWP715 dosing, LDH, GOT level and spleen weight used as a parameter against fatigue and stress states were recovered almost to the nomal level. Furthermore, lipid peroxidation due to $CCl_4$ was significantly inhibited by DWP715 treatment. These results suggest that DWP715 seems to metabolize the blood alcohol rapidly and to restore the damaged liver and fatigue conditions which was caused by alcohol metabolism to normal condition.

Recently, many hangover cure products containing natural ingredients have been made available in the market that are effective for alcohol-related liver damage or for improved liver function. However, the cure for of liver damage or medication for improved liver function are different from hangover cure. Therefore, the efficacy hangover cure products needs to be verified. In this study, we investigated and compared the ameliorating effect of four commercially available hangover cure products on acute ethanol-induced hangover in Sprague - Dawley rats. The four samples were labeled as C, M, R, and S. The efficacy of the samples was evaluated based on the serum concentration and area under the curve (AUC) of blood ethanol and acetaldehyde concentrations to quantitatively assess the hangover cure effect. Ethanol administration to the rats significantly raised the serum alcohol and acetaldehyde levels. The Cmax reduction rates of ethanol for the samples C, M, R, and S were 5.9%, 3.1%, 8.4%, and 11.7%, and the AUC were 8.9%, 2.2%, 12.1%, and 19.6%, respectively, whereas the Cmax reduction rates of acetaldehyde were 14.2%, 15.2%, 28.2%, and 35.0%, and the AUC were 21.6%, 7.5%, 22.4%, and 29.9%, respectively. In conclusion, all samples showed a tendency to relieve hangover in the order of S, R, C, and M in terms of the ethanol concentration, but only sample S showed a statistically significant decrease in both Cmax and AUC for ethanol and acetaldehyde. These results suggest that an objective method for verifying the efficacy of hangover cure products is lacking.

The purpose of this study was to identify the effect on plasma levels of lipid and lipid peroxidation by administration of lactic acid bacteria (Lactobacillus bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus) fermented Orostachys malacophyllus (FOM) in alcohol fed rats. Male Sprague-dawley rats were randomly divided into seven groups: normal diet group (N), alcohol treated group (C), 2.5% (w/w) or 5% (w/w) OM treated group (2.5OM, 5OM), 2.5% (w/w) or 5% (w/w) fermented OM treated group (2.5FOM, 5FOM) and silymarin treated group (SM) as a positive control. As a result of measuring serum total lipid, C group were increased total lipid, free fatty acid content and were decreased HDL-cholesterol content, but 5FOM group were significantly decreased lipid content and were increased HDL-cholesterol content and accordingly reduced the incidence of atherosclerosis. Serum total protein content was similarly measured in all groups and serum albumin content was decreased in alcohol feeding groups compared to the N group. The 5FOM group had significantly decreased liver and serum triglycerides compared to the C group. The TBARS content in the liver, serum, testis, kidney, spleen, and heart were slightly decreased in the 5FOM group compared to the C group and the 5FOM group had an increased glutathione concentration. The 5FOM treatment was showed analogous results to those of the SM treatment, suggesting that FOM is can improve the lipid profiles of alcohol-fed rats.

It has long been recognized that dropwort contains specific funtional subtances for protecting human liver and preventing and curing its diseases, and thus it has been widely utilized in traditional folk remedy. In the present study. fresh of fermented extract of dropwort shoots grown on dryland and fresh extract of those grown on flooded fie1d were fed to the rats suffering from acute, subacute or chronical toxication induced by alcohol administration, and their affects were investigated. Administration of alcohol to rats and mice for 2 days at 5ml of 30% EtOH/kg/day raised total cholesterol and total glyceride which were, however, great1y supressed when alcohol was administered to the laboratory animals previously fed on fresh or fermented extract of dryland dropwort, or fresh extract of flooded field-grown dropwort for 20 days, without significant differences among the extracts. The levels of alanine aminotransferase and aspartate aminotransferase which were raised by alcohol adminstration were also lowered by feeding dropwort extract, among which that of fermented dryland-grown one was more effective than the other two. Chronic alcohol toxication was induced to rats by administering 10% alcohol for 10 months and fermented dropwort extract or tap water was fed to the rats for 5 days. The rats fed on fermented dropwort extract were lower in total cholesterol by 40% and in tota1 glyceride by 60% than the control. Alanine aminotransferase and aspartate aminotransferase in the rats fed on fermented dropwort extract were decreased by 87.2% and 91.7%, respectively, compared to the control, and the rats recovered almost to normal. Activity of alkaline phosphatase, catalase, superoxide dismutase or glutathione peroxidase changed greatly by alcohol administration in the rats suffering from chronic as well as acute toxication. The extract of fermented dry land dropwort significantly lowed the activity of those enzymes, especially, alkaline phosphatase and superoxide dismutase. The present results suggesting the possible medicinal effect of fermented dropwort extract to liver diseases.

The researcher examined the relationship between dating violence and drinking behaviors. Study participants included 440 Korean College students(184 males and 256 females) currently involved in heterosexual dating relationships. Participants' ages ranged from 17 to 30(M=20.08, SD=1.89). Questionnaires and psychological tests used included: Straus' Conflict Tactics Scale, Alcohol Use Disorder Identification Test(AUDIT), Cooper's Revised Drinking Motives Questionnaire(DMQ), and Index of Family Alcohol Use. Research designs were 2(gender) × 2(experience of inflicting dating violence), i.e. 2-way MANOVAs. Results suggest students who drink one or more times a week are more likely to commit acts of violence toward their dating partners than students drinking less often. The study revealed males tend to drink with higher social, enhancement, conformity and coping motives than females. The study also showed that students inflicting dating violence drank with higher coping motives than students who did not. Males showed more hazardous, dependent and harmful drinking patterns than females. Also, students who had inflicted dating violence showed a higher degree of these characteristics (hazardous, dependent and harmful drinking patterns) along with a greater family history of alcohol use than participants who had not inflicted dating violence. The findings showed significant 2-way interactions in dependent and harmful drinking patterns. Simple main effect analysis revealed that differences in dependent and harmful drinking patterns in males are more significant than the same differences in females.

Formaldehyde has widely been used for the cross-linking of polyvinyl alcohol polyvinyl alcohol polymer. The effects of formaldehyde on the water resistance of MDF cement composites were investigated as a function of types of catalyst, base or acid, and the amount of formaldehyde. The acetalization, reaction of OH group of PVA with aldehyde, was ended incompletely under base atmosphere. However, by addition of citric acid, the cross-linking of PVA polymer could be acheved through acetalization of PVA and formaldehyde. The effects of these different patterne according to the types of catalyst on the water resistance of MDF cement were studied by the preparation of PVA films and MDF composites. Thanks to the cross-linking reaction of PVA polymer chains by formaldehyde, the modified PVA films and MDF composites showed a good water-resistant propety. The modified MDF cement composite to which 3 wt% formaldehyde and 1 wt% cirtic acid were added showed 80% of initial flexural strength and good interfacial state between cement grain and polymer matrix. However, 4 wt% formaldehyde deteriorted the processing conditions, microstructures and eventually the flexural strength, causing sharp increase in the viscosity of sample dough during the mixing process. To study the relatins of flexural strength and interface of cement grain and polymer matrix, SEM and MIP measurement were performed.
