To investigate an effect of the ethanol extract of Lycium chinense(EELC) on the activities of enzymes scavenging oxygen free radicals or detoxicating alcohol. The ground Lycium chinense was extracted with 30% edible ethanol and then diluted with 6% ethanol to contain 2% EELC(w/v). Three different groups of male Sprague-Dawley rats had taken a drink EELC, ethanol(ETH) or water(control), respectively for 2 months. At the end of experimental period, the animals were sacrificed and obtained the following findings. The EELC-treated animals showed the highest activity of hepatic glucose-6-phosphatase among three groups. The activities of xanthine oxidase and cytochrome p-450 from EELC treatment group were lower than those from ETH-treated group. However, the activity of superoxide dismutase was higher in the EELC-treated group than the ETH-treated(p<0.005). Furthermore, hepatic alcohol or aldehyde dehydrogenase activity, and glutathione content and glutathione peroxidase were significantly higher in EELC-treated animals than in ETH-treated those. The activity of glutathione S-transferase in liver was appeared the orderly higher value in EELC, ETH and control-treated group. As the result, EELC may affect the reduction of oxygen free radical production and help the detoxication of ethanol.

Saccharomyces cerevisiae and Zygosaccharomyces rouxii are known to produce alcohol in gochujang. To reduce alcohol production, garlic and chives were applied to gochujang solution to find their inhibitory effect on S. cerevisiae and Z. rouxii. The 70% ethanol extract of garlic and chives showed significant inhibition activity against S. cerevisiae and Z. rouxii, showing growth inhibition zone of 14.00±0.00~25.33±0.58 mm by disc diffusion method. In addition, the addition of 70% ethanol extract of garlic and chives in 10% gochujang solution spiked with S. cerevisiae and Z. rouxii reduced the numbers of total aerobic bacteria (below 7 Log CFU/g) and yeast (below 4 Log CFU/g), alcohol content (below 0.30%), respectively. In conclusion, the addition of garlic ethanol (70%) extract or chives ethanol (70%) extract to gochujang inhibited the growth of S. cerevisiae and Z. rouxii, resulting in reduced alcohol content in gochujang. For further study, it is necessary to conduct food application experiments by using real gochujang paste.

Objectives : Our study was designed to assess whether the extract of Angelica gigas can lower serum alcohol and acetaldehyde concentration in drunken rats. Methods : We divided Sprague-Dawley male rats into 3 groups of a Vehicle control, Positive control and Angelica gigas group. Serum alcohol and acetaldehyde levels were checked at baseline, 0.5, 1, 2 and 4 hours after drinking ethanol. Independent t-test was performed to assess the difference of the serum concentrations between the Angelica gigas induced group and the control group. Results : Angelica gigas lowered the serum acetaldehyde concentration. However, it did not lower alcohol concentration effect. Conclusions : We assume that Angelica gigas could be effective for alcohol induced hangover.

Traditionally, aqueous extracts of Puerariae radix had been used for the treatment of alcohol-related problems. In the present study, the effect of Puerariae radix on cell proliferation and expression of nitric oxide synthase (NOS) in the dentate gyrus of alcohol-intoxicated rats were investigated via 5-bromo-2' -deoxyuridine (BrdU) immunohistochemistry and nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) histochemistry, respectively. Sprague-Dawley rats weighing 150 ± 10 g were divided into four groups: the control group, the Puerarias radix-treated group, the alcohol-treated group, and the alcohol- and Puerariae radix-treated group. The numbers of both BrdU-positive and NADPH-d-positive cells in the dentate gyrus were inhibited significantly by alcohol administration, while Puerariae radix treatment was shown to increase those numbers. In this study, it was revealed that Puerariae radix possesses protective effect against alcohol-induced suppressed new cell formation and NOS expression in the dentate gyrus. Based on the results, it is possible that NO, which might play an important role in the regulation of cell proliferation, is a major target of the toxic effects of alcohol.

We conducted a single blind, randomized and crossover clinical trial in order to test the effect of curcuma longa herbal mixture on blood alcohol level and alcohol hangover in 19 healthy volunteers. The herbal mixture did not show a statistical significance in $C_{max}$, $T_{max}$ and AUC in alcohol disposition. The herbal mixture did not also ameliorate blood laboratory result after alcohol consumption. In contrast, the herbal mixture is shown effective on alcohol hangover. In behavior tests, the fewer subjects in the herbal mixture group were impaired with alcohol than in reference group. Moreover, the symptom severity score in the herbal mixture was lower than that in reference group. The symptom severity score was statistically especially in stomach pain, diarrhea, concentration disorder, memory and bad breath at drinking day and one day after drinking. These results indicate that the general symptoms seemed to be recovered as time goes on. From these results, it was suggested that the herbal mixture have a beneficial effect on modulating alcohol hangover.

Objectives: This pilot study tested the effectiveness of a brief alcohol-related intervention delivered by the social media app WeChat to teach about ethanol-induced facial flushing and increase the willingness of students who see another student flushing to suggest that he or she should reduce or stop drinking. In the context of Chinese drinking culture, it is sometimes socially difficult to refuse a drink, even when experiencing physical discomfort, such as flushing. Methods: Classrooms of students in a medical university in China were randomly assigned to the intervention or control group. Students in the intervention group were invited to view 3 alcohol education lessons on WeChat during a 2-week period. A pretest and posttest before and after the 2-week period assessed changes in students' willingness to intervene if they saw someone flush while drinking. Data were collected about students' alcohol use and their ratings of the lessons. Results: Mixed-design analysis of variance yielded a significant time-by-treatment interaction effect on the variable of willingness to suggest that a flushing person stop or slow down their drinking, and the change was significant between the intervention and control groups. One-way analysis of covariance yielded a significant treatment effect at the posttest, after controlling for the pretest score. Students rated the lessons above the midpoint of the scale for being informative, interesting, and useful. Conclusions: The pilot study showed that a brief alcohol-related intervention delivered by WeChat could produce a measurable positive change in the willingness of university students to suggest that a student who flushes should stop drinking. This pilot study also suggested improvements for future lessons and evaluation design.

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.

Objectives : This study sought to examine relationships between alcohol drinking and cardiovascular disease mortality and all-cause mortality. Methods : From March 1985 through December 1999, 2,696 males and 3,595 females aged 55 or over as of 1985 were followed up for their mortality until 31 December 1999. We calculated the mortality risk ratios by level of alcohol consumption. Among the drinker, the level of alcohol consumption was calculated by the frequency of alcohol comsumption and the type of alcohol. Cox proportional hazard model was used to adjust for confounding factors. Results : Among males, compared to abstainer, heavy drinker had significantly higher mortality in all cause(Risk ratio=1.35), cardiovascular disease(Risk ratio=1.52) and cerebrovascular disease(Risk ratio =1.66). Although not significant, moderate drinker had lower ischemic heart disease mortality(Risk ratio =0.38). Among females, there was no statistically significant association between alcohol comsumption and mortality. Conclusion : The results of this study suggest that alcohol drinking has harmful effect on all-cause mortality, cardiovascular disease mortality and cerebrovascular disease mortality among males, especially in heavy drinker among males. Minimal evidence on protective effect for cardiovascular disease mortality in low or moderate drinker is observed.

To investigate the effect of alcohol on the ultrastructural changes of liver the experiment was undertaken by dividing in 3 groups (control, alcohol and alcohol-camitine groups). Chronic administration of ethanol to adult rats led to striking fat accumulation and ultrastructural changes in the liver. Mitochondrial abnormalities. dilation of endoplasmic reticulum, focal cytoplasmic degradation, dilation of bile canalicli and swelling of nucleus were observed. In alcohol-carnitine group, there were less fat accumulation and ultrastructural changes than alcohol group. These alterations suggest that ethanol is very toxic to the liver and carnitine prevents fat accumulation induced by alcohol. 알콜이 흰쥐 간장의 미세구조에 미치는 영향을 관찰하기위해 대조군, 알콜 처리군, 알콜-carnitine처리군으로 나누어 실험하였다. 만성적인 알콜 투여는 간에서의 지방축적을 유발하였으며 미토콘드리아의 이상, 소포체의 팽대, 세포질의 손상 Bile canaliculi의 확장 및 핵의 수축 등의 미세구조적 변화를 가져왔다. 알롤- carnitine으로 처리한 군에서는 지방의 축적과 미세구조의 변화가 알콜 처리군에서 보다는 약하였다. 이러한 구조적 변화는 알콜이 간에 매우유독하며 carnitine은 알콜에 의해 유발된 지방의 축적을 방지해 보여주는 것으로 사료된다.
