Effects of the extract of oriental herbal composition, Jang Baek Union (JBU), on hangover and liver function were studied in rats. To investigate anti-hangover effect, alcohol concentration and acetaldehyde concentration of blood were measured after oral ethanol treatment. Blood alcohol concentration was significantly reduced by pre-treatment of JBU extract. The effect of JBU extract on the blood acetaldehyde concentration was more significant than commercial product used as a positive control. To investigate hepato-protective effect, serum GOT and GPT levels and histological changes of liver tissue were analyzed in $CCl_4$-treated rats. JBU extract adminstration significantly inhibited the increase of serum GPT and GOT levels induced by $CCl_4$-treatment. Moreover, histological injuries of liver tissue such as fatty changes and sinusoidal leukocytosis were inhibited by JBU extract.

It has been estimated that up to $80\%$ of all marine accidents have human elements as a cause. Out of these, human elements of crew fatigue is one of the main causes of marine accident. Crew fatigue involves sleep, schedule, workload, off-time, alcohol, health and stress. With a ship handling simulator, the effect of alcohol on ship operational performance is studied for each 0.05 and 0.08 $\%$ blood alcohol concentrations(BAC). The main effect of alcohol was found that ship operational performance was significantly impaired by alcohol compared to that in the non-alcohol condition. The results of this research can be used as basic data to minimize marine accidents.

Purpose: This article tried to find the changes of the eye and a correlation depending on watching a smartphone and taking in alcohol. Methods: This paper conducted the refraction inspection, the radius of corneal curvature, tonometry and the corneal thickness measurement and analysis for 31 persons (18 males and 13 females) who have healthy drinking habit, not having the medical history of taking medicine related with disorders of the eye, a mental disease, systemic disease and alcohol metabolism. Results: Of respirations depending on watching a smartphone, the alcohol concentration was significantly decreased in 15 minutes, 30 minutes, 45 minutes, 60 minutes and the convalescent stage. (p<0.01, p<0.001) As the result of comparing the refraction inspection after and before watching a smartphone when drinking alcohol, there was a significant difference in the cylindrical power and the axis. (p=0.005, p=0.001) The change of intraocular pressure depending on watching a smartphone after drinking alcohol was decreased significantly from 30 minutes (p<0.001), and watching a smartphone didn't have any significant effect on the corneal thickness depending on the elapsed time from when drinking alcohol. Conclusions: Watching a smartphone and taking in alcohol had a significant effect on the cylindrical power and the axis. Watching a smartphone and taking in alcohol which may cause the visual function-strain are the factors that need to consider before the refraction inspection.

Purpose: This study was conducted to evaluate the role of adiponectin, leptin, and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) in obese children, and to elucidatethe relationship between these adipokines and insulin resistance. Methods: A total of 61 obese children (M : F=42 : 19, mean age 11.2${\pm}$1.3 years) admitted to our facility between March 2004 and June 2005 were included in this study. Patients were divided into three groups based on their NAFLD status obese children without fatty liver (N=23); obese children with simple steatosis (N=20); and obese children with non-alcoholic steatohepatitis (NASH) (N=18). The serum levels of adiponectin, leptin, and TNF-${\alpha}$ were measured, and insulin resistance determined by homeostasis model assessment (HOMA-IR) was calculated to estimate insulin resistance. In addition, the VSR (visceralsubcutaneous fat ratio) was estimated using abdominal computed tomography. Results: There was no difference in serum TNF-${\alpha}$ and leptin levels observed between the 3 groups (22.13${\pm}$6.37 vs. 21.35${\pm}$6.95 vs. 25.17${\pm}$9.30; p=0.342 & 20.29${\pm}$8.57 vs. 16.42${\pm}$6.85 vs. 20.10${\pm}$7.86; p=0.330). However, the serum adiponectin level was significantly lower in children with non-alcoholic steatohepatitis (NASH) than in the other two groups (6.08${\pm}$1.38 in children without steatosis vs. 5.69${\pm}$0.79 in simple steatosis vs. 4.93${\pm}$1.75 in NASH; p=0.026). In addition, the VSR was significantly increased in the NASH group (0.31${\pm}$0.08 vs. 0.32${\pm}$0.11 vs. 0.47${\pm}$0.14; p=0.001), and HOMA-IR revealed a significant difference among the three groups (4.77${\pm}$3.67 vs. 6.89${\pm}$7.05 vs. 10.42${\pm}$6.73; p=0.000). However, there was no significant correlation observed between the adiponectin levels and the HOMA-IR or the VSR (r=-0.117; p=0.450 & r=-0.106; p=0.499). Conclusion: Insulin resistance may affect the development of hepatic steatosis and steatohepatitis in children, and the results of this study suggest that, of several adipokines evaluated, adiponectin is important in the progression of steatosis to steatohepatitis in obese children.

This study was purposed to compare the activity of alcohol dehydrogenase and antioxidative effects of several plant extracts in the alcohol-treated rat liver. Sprague-Dawley rat weighing about 200 g were divided into the following 6 groups : normal, alcohol group and 4 different plant extracts administrated groups(Soybean sprout, Pine needle, Lentinus edodes, acanthopanacis cortex). Each plant extract was administrated orally by 200mg/kg b.w./day for 8 days before the alcohol treatment (5 g of 30% alcohol /kg b.w. by i.p.injection). All rats were sacrificed at 90 min after the alcohol treatment. The alcohol concentrations in serum of Soybean sprout and pine needle group were significantly lower than the Lentinus edodes and Acanthopanacis cortex group. The activity of alcohol dehydrogenase in the hepatic cytosol of Soybean sprout and Pine needle group was also significantly higher than the alcohol and the other groups However, the activity of catalase seemed not to be affected, although the extract groups showed slightly higher activities of catalase than the alcohol group. These results may indicate that the extracts of Soybean sprout and Pine needle were relatvely effective on the alcohol degradation. the activity of blutathione-peroxidase and lipid peroxidaton of all of the extract groups were significantly lower than the activity of alcohol group. These results can suggest that all of the use plant extracts more or less have an antioxidative effect on the alcohol-induced oxidation and especially, extracts of Soybean sprout and Pine needle have an stimulating effect on the alcohol absorption and degradation.

The aim of this study was to investigate the potential effects of extracts from silkworm (Bombyx mori L.) that was fermented with Bacillus subtilis KACC 91157 at the levels of 1%(v/w), 2.5%(v/w), and 5%(v/w) in alcohol-fed rats. Sprague-Dawley rats were divided into seven groups: normal group (N), alcohol treated group (C), silymarin treated group (PC, positive control), 5% silkworm powder treated group (SP5), 1% Bacillus subtilis-fermented silkworm powder treated group (BSP1), 2.5% BSP treated group (BSP2.5), and 5% BSP treated group (BSP5). The activities of AST, ALT, ALP, and LDH in the serum and the triglyceride concentrations in the liver and serum were increased by alcohol feeding but were reduced in the BSP5 group. In addition, the contents of total lipids, free fatty acids, and total cholesterol were increased in the alcohol-fed group but were reduced in the BSP5 group. The activities of ADH, ALDH and ADH, ALDH protein levels in the liver were increased in the BSP5 group. The TBARS contents in the liver, serum, liver mitochondria, and liver microsomes were slightly decreased in the BSP5 group compared to the C group. The hepatocytes in alcohol-fed rats contained numerous large droplets; however, BSP5 treatment prevented alcohol-induced lipid droplet accumulation in the hepatocytes. Based on these results, extracts from Bacillus subtilis-fermented silkworm (Bombyx mori L.) have significant potential for development into a functional health food that can improve alcoholic fatty liver conditions.

This study was designed to investigate whether consumption of onion wine can reduce serum biomarkers of ethanol-induced fatty liver in rats. Male Sprague-Dawley rats were initially trained for meal feeding to prevent reduction of food intake. After the training period, rats were weight-matched and assigned to the following three groups: 1) a control group fed a control liquid diet containing maltose-dextrin, 2) an ethanol group fed an ethanol liquid diet with 95% ethanol, and 3) an onion wine group fed the same ethanol liquid diet but containing onion wine extract at 1 mL/d/group. All three groups were fed daily for 6 weeks. At 0, 3, and 6 weeks, blood was collected via the orbital sinus following overnight food deprivation and terminally organs collected. Blood lipids and transaminase activities significantly increased in the ethanol-fed group but significantly reversed in the onion wine-fed group. The hepatic levels of fat and cholesterol at 6 weeks were significantly elevated by ethanol administration but significantly reduced by onion wine. These findings indicate that onion wine may ameliorate ethanol-induced fatty liver by lowering hepatic and blood lipid levels.

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.

This study investigated whether or not Citrus unshiu peel extract (CPE) affects fat accumulation in livers of rats fed an ethanol-containing liquid diet. Initially, male Sprague-Dawley rats were housed individually in stainless steel, wire-bottomed cages with free access to a Lieber-Decarli control liquid diet. Rats were divided by body weight into three groups of eight each: one group of rats was fed the Lieber-Decarli control liquid diet devoid of ethanol (control), another was fed the Lieber-Decarli ethanol diet (ethanol), and third was fed the same ethanol diet except containing CPE. All three groups were fed their respective diets for 6 weeks. Serum and liver lipids were analyzed and liver histology performed. Body weight did not differ among the groups over the 6-wk duration. Histology images showed that CPE administration significantly improved fat accumulation in livers, which was induced by ethanol diet. Serum levels of transaminases and lipids also were reduced by CPE consumption. Taken together, the results indicate that CPE may protect ethanol-induced fatty liver by lowering fat accumulation in both the liver and blood. The protective effects of CPE appear to be due to its phenolic contents.

Zinc is an essential trace element participating in many physiological functions and notably an important function for sperm physiology. Zinc-enriched yeast strain, Saccharomyces cerevisiae, isolated from tropical fruit rambutan. This strain contained 306 ppm zinc concentration and other components contained by K 28,640 ppm, Mg 2,342 ppm, Na 1,048 ppm, Ca 366 ppm, Fe 236 ppm and Mn 4 ppm. The serum concentration of testosterone was decreased in ethanol treatment rats. As compared with ethanol treated control rats, the zinc-enriched yeast strain supplementation showed significantly increased the testosterone concentration in serum. In addition, zinc concentration in serum was decreased in alcohol treatment, but this reduction was significantly increased by zinc-enriched yeast strain supplementation in ethanol feeding rats. These results indicate that zinc-enriched yeast Saccharomyces cerevisiae strain could play an important role in the sperm physiology by the marked elevation of serum testosterone concentration.
