Purpose: There are many patients visited to ED in an alcohol intoxicated state. For these patients, it is difficult to predict by only clinical examination whether he/she would have brain lesion. The purpose of this study is to research whether it is possible to predict brain lesion by only clinical examination findings, with comparing patients with/without actual brain lesions. Methods: A retrospective study was performed at a university hospital for the period 11 months with the medical records. As for the inclusion group, head trauma patients with objectively proved drunk, judging by their blood ethanol concentration, and performed the brain CT were selected. In terms of medical record, Glasgow coma scale (GCS), the presence of neurologic abnormalities, the presence of lesion on brain CT of the patients, were examined. From laboratory results, blood ethanol concentration, platelet count, prothrombin time (PT), activated partial thromboplastin time (aPTT) and glucose concentration were identified. Results: For this study, there were total 80 patients of inclusion group. There was no statistically significant difference in terms of GCS score and neurological examination abnormalities, between the group with brain lesion and the group without brain lesion on brain CT. Conclusion: Alcohol intoxicated patient with head trauma visits the ED, it is not possible to distinguish or determine whether brain lesion exists or not by only clinical findings. In order to check the lesion existence, the image examination, therefore, should be considered and performed.

Over-consumption of alcohol leads to many side-effects such as malnutrition, liver disease, and neuronal disorders and many investigators have tried to identify methods for preventing the side-effects of drinking. This study was carried out to investigate the effect of the beverage contained green tea catechins (GTC) on the alcohol administered rats. We observed that blood alcohol concentration level decreased significantly in plasma. GTC (200 mg/kg) also reduced the aspartate aminotransferase (AST) and alanine aminotransferase (ALT) level of the intoxicated rats. These results suggest that GTC may be useful for the prevention and therapy of hepatotoxic pathogenesis.

Background: This study was carried out for the purpose of comprehensively evaluating the mercury exposure level of residents in several areas and the correlation between hair mercury concentration and blood mercury concentration. Method: One thousand one hundred ninety seven subjects were sampled from 30 sites using random assignment sampling. We performed a questionnaire survey and measured the level of total mercury in hair and blood samples from all subjects. Results: The geometric mean concentrations of hair and blood mercury in all subjects were 1.27 mg/kg [95% confidence interval (CI): 1.23-1.32 mg/kg] and 5.24 ${\mu}g/L$ [95% CI: 5.07-5.41 ${\mu}g/L$], respectively. Male (1.56 mg/kg in hair, 6.00 ${\mu}g/L$ in blood) was significantly higher than that of female (1.03 mg/kg in hair, 4.56 ${\mu}g/L$ in blood), and the concentrations were elevated as age increased up to the 50s. Education, smoking, alcohol drinking, and using of pesticides were also shown to influence mercury concentrations in hair and blood. The ratio of hair/ blood mercury concentration was 261.3. The total mercury concentration in hair was identified to be significantly related with total mercury concentration in blood (r=0.814, p<0.001). Conclusion: The geometric mean concentrations of hair and blood mercury were higher than the levels provided in international recommendations. The total mercury concentration in hair was positively correlated with the concentration in blood. The results of this study suggest that hair mercury be considered as a useful tool for the evaluation of mercury exposure.

To examine the effects of alcohol consumption on body fluid restoration and fat mobilization following exercise induced dehydration, nine healthy collegiate men ($24{\pm}2yrs,\;177{\pm}5cm,\;72{\pm}8kg,\;10.5{\pm}2.3%$ body fat) underwent three experiments. In each experiment, subjects ran on a treadmill to reduce individual body mass to $2.2{\pm}0.1%$ and consumed one of three beverages containing 0, 4, or 8% alcohol over 60 min followed by 4 hr of resting recovery. They consumed approximately 150% of weight loss $(2053{\pm}204,\;2091{\pm}149,\;and\;1943{\pm}295mL)$ and content of alcohol was $9.9{\pm}1.0(0%),\;71.9{\pm}5.1(4%)$, and $132.2{\pm}20.1g$ (8% trial). Body weight, urine volume and samples, blood samples, and thirst sensation were measured five times; at baseline, immediately after exercise, and 0, 1st, and 4th hr of recovery. Blood alcohol concentration after ingestion was $0.0{\pm}0.0(0%),\;0.1{\pm}0.02(4%)$, and $0.2{\pm}0.03%$ (8% trial). No differences in blood sodium and potassium concentrations, and urine specific gravity were noticed over time periods and trials. Thirst sensation tended to be elevated in all trials immediately after exercises and urine output was elevated during the recovery. The magnitude of changes in these variables was proportional to the alcohol concentrations, but not statistically significant. While serum osmolality was not different among trials and time periods in 0 and 4% trials, it was higher during recovery than the baseline in the 8% trial (P<0.01). Triglycerides did not change throughout the time period and among trials. Free fatty acids were elevated after exercise in all trials and 4th hr of recovery in 0% (P<0.05). Subjects' net body fluid balance at 4th hr of recovery was negatively maintained and proportional to alcohol concentrations. Only 8% trials showed a significant reduction at 1st and 4th hr of recovery compared to 0 hr. The results suggested that diuretic effect of alcohol after moderate level of dehydration appeared dose dependent, but beverage containing alcohol up to 4% did not induce impaired rehydration than alcohol free drinks. Alcohol effects on fat mobilization during recovery appeared to be minimal and the mechanism is unclear.

A dose, 1g/kg of ethanol produced experimental hyperuricemia in mouse. Ginseng saponins were tested for their ability to alter the hepatic xanthine oxidase activity and the blood level of uric acid in the ethanol-treated mouse. Intraperitoneal injection of ginseng saponin 4mg/kg markedly decreased the xanthine oxidase activity in the ethanol-treated mouse liver. It was also observed that ginseng saponin reduced the blood concentration of uric acid in experimentally induced hyperuricemia by alcohol treatment. In vitro, it was found that a low concentration of ginseng saponin in the reaction mixture incresed the hepatic xanthine oxidase activity, while a high concentration inhibited both enzyme preparations of normal and ethanol treated mice. In contrast with the xanthine oxidase, uricase activity was not influenced by ginseng saponin as well as in vivo. These results suggest there is a possibility that ginseng saponin may have some therapeutic effect on gout and other hyperuricemia syndrome.

Objectives : Oxidative stress seems to play a major role in mechanisms by which ethanol causes liver injury. Previous studies have shown that treatment with Chungganhaeju-tang (Qingganjiejiu-tang, CGHJT) has protective effects on alcoholic liver disease. The aim of this study was to investigate the effects of Chungganhaeju-tang on oxidative stress. Materials and Methods : In vitro, we evaluated the inhibitory activities of CGHJT on DPPH (1,1-diphenyl-2-picryl-hydrazyl), xanthine oxidase, trypsin, and hyaluronidase, and measured cell viability, and proliferation. In the cell culture model, we measured the activities of superoxide dismutase (SOD), and catalase (CAT) after CGHJT treatment in C34 and E47 cell lines, HepG2 cells transfected with/without the cytochrome P450 2E1 (CYP2E1) gene. In vivo, we measured malondialdehyde levels in the liver tissue and alcohol concentration in the blood. Results : CGHJT showed significant free radical scavenging activity against DPPH and xanthine oxidase in the in vitro study, and increased cell viability, proliferation, and activities of superoxide dismutase, catalase in C34 and in E47 cell lines. CGHJT reduced malondialdehyde levels and blood alcohol concentration in vivo, as well. Conclusions : This study suggests that CGHJT has antioxidant effects on oxidative stress by reducing lipid peroxidation and inhibiting the ethanol induced suppression of antioxidant enzyme activities.

Recently, much attention has been paid to developing various kinds of fermented herbal extracts, a new type of traditional herbal medicine, in the field of Korean traditional medicine. The fermentation of medicinal herbs is intended to exert a favorable influence on digestability, bioavailavility and pharmacological activity of herbal extract in the gastrointestinal tract. It also produces a number of fermentation products that intensify the nutritional and pharmacological aspects of the medicinal herbs. In order to develop a functional beverage of alleviating the aftereffects of the previous drinks, the extracts (HP-1) of fermented herbal mixture, including Artemisia capillaris Thunb., Lonicera japonica Thunberg, and Hovenia dulcis Thunb., were prepared and the medicinal effect as a hangover cure was evaluated in ethanol-loaded rats. The enzyme activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase-2 (ALDH2) were analyzed by measuring the concentration of blood ethanol and acetaldehyde. The mRNA expression of ADH and ALDH2 was also investigated through RT-PCR analysis. In the HP-1-treated group, the concentration of blood ethanol was significantly reduced at one hour after loading of ethanol, as compared to that in the saline-treated group. The reduced ethanol was converted to acetaldehyde, which resulted in rapid increase in acetaldehyde concentration in an hour. Acetaldehyde was started to decrease at 5 hours after ethanol loading. It implies that HP-1 is highly effective to stimulate the activities of ADH and ALDH2. The HP-1 treatment also activated the mRNA expression of ADH and ALDH. This study suggests that fermented herbal extract, HP-1 can be used as a functional beverage of alleviating the alcohol-induced hangover symptoms by stimulating the activities and gene expression of hepatic alcohol metabolizing enzymes.

There was not noticeable differences in decreasing blood alcohol concentrations between Korea and China-produced Hovenia dulcis $T_{HUNB}$, showing only 1-2 % higher decreasing rate for Korea-produced seed extracts than those from China. It was also found that the blood alcohol decreasing ability was greatly enhanced by partitioning the crude extracts produced from both places. The both extracts (crude and partitioned) accelerated the reducing rate of blood alcohol concentrations down to 1-2 hours, compared to that of control (taking only ethanol). The crude extracts from imported seeds seemed to have slightly better effect on improving in vivo ADH and ALDH activities than domestic ones; however, not for partitioned extracts. It was interesting that the partitioned extracts from both countries enhanced ADH enzyme activity up to 60% than the crude, compared to the control, while ALDH activity was not much affected by the partitioned extracts. It was also confirmed that both ADH and ALDH activities were well balanced in controlling blood alcohol concentration maintaining 28-29% of enzyme activities in vivo. The extracts proved to have better effect on enhancing ALDH activity than ADH activity, which is one of possible explanation that Hovenia dulcis $T_{HUNB}$ can effectively relieve the hangover by fast decreasing acetaldehyde concentration in the liver and blood. GST activity was also increased in the range of 120 to 300% by adding crude or partitioned extracts from both countries; however, there was no difference in enhancing GST activity between the extracts from two countries. The extracts showed competitive inhibition with GST activity, showing the reduction of enzyme activity at higher than 0. 6 (g/L) of the imported extracts.

This study was carried out to assess whether feeding of alcohol-fermented feeds (AFF) affects the nutritional metabolism and growth characteristics of Korean native steers. Ten steers were randomly assigned to one of two treatment groups. The dietary treatments were AFF (50% commercial beef cattle feed+30% alcohol-fermented soybean curd dregs+20% rice straw) and control (80% commercial beef cattle feed+20% rice straw). The change of serum metabolites and growth characteristics were measured every two months during the whole twelve months experimental period and the relationships between serum metabolites and growth characteristics were simultaneously analyzed. Four hours after feeding AFF, serum alcohol concentration reached its peak with a significantly higher value than that after control feeding (11.9 and 4.9 mg/dl, respectively). Serum glucose and inorganic phosphorus (IP) concentrations (63.1 and 8.4 mg/dl, respectively) of steers fed AFF were higher than those (56.6 and 7.0 mg/dl) fed the control diet. In both treatments, the serum glucose concentration rapidly increased when body weight (BW) of the steer reached about 600kg, while IP concentrations were rapidly diminished at that BW. Lower concentrations of both blood urea nitrogen (BUN) and cholesterol were observed in steers fed AFF up to 450 kg of BW. The IP concentration was correlated with concentrations of BUN, cholesterol and glucose in AFF fed cattle but not in the cattle fed control diets. Average daily gain was higher in steers fed AFF than steers fed control, particularly during the growing stage of cattle. These findings indicated a capability of AFF to improve BW gain of Korean native steers by decreased protein degradation as well as increased fat synthesis.

Alcoholic fatty liver disorder has become a frequent health concern worldwide. To investigate the effects of Brassica oleracea (B. oleracea) sprout extract (BOE), the present study was designed with alcoholic fatty liver in the rat. Initially, the effects of BOE on liver parameters were examined. Male rats were divided into five groups. The normal control group was fed the normal diet, and the BOE group was fed the high fat diet and ethanol with/without BOE for 4 weeks. After 4 weeks feeding period, rats were sacrificed and their livers and blood were used for fatty liver-related biomarkers analyses. As a result, BOE ameliorated fatty liver-related enzymes profiles in liver tissues and also reduced blood alcohol concentration in rat model. We demonstrated that BOE protected the high fat diet and alcohol-induced fatty liver in rat model. Furthermore, BOE increased detoxificative abilities against alcohol.
