Effects of $Biozyme_{R}$ and $\textrm{Business}_{R}$ on alcohol metabolism in rats, and on the activities of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH) were studied in vitro. Alcohol concentration in rat blood was decreased after the treatment of Business(3.3 mι/kg, Biozyme 1.67 mg/wι) and Biozyme(3.3 mι/kg, 1.67 mg/mι) prior to the administration of ethanol(25%, 0.83 g/kg). And the acetaldehyde concentration of rat blood was also decreased when compared with control values in the same condition. Effects of Biozyme on ADH and ALDH activity were also studied. While the ALDH activity was elevated in the presence of Biozyme(2 $\mu\textrm{g}$/assay), the ADH activity was not influenced by Biozyme at the concentration range from 2 $\mu\textrm{g}$/assay to 0.2 mg/assay. In summary, Biozyme accelerated the rate of ethanol metabolism and the acceleration might be due to the increase in ALDH activity.vity.

These studies were conducted to investigate the alcohol degradation effects of the extract of herbal composition (DTS20) containing Viscum album L., Lycium chinense L., Inonotus obliquus and Acanthopanax senticosus H., on the alcohol administered mice. To investigate anti-hangover effect, alcohol and alcohol dehydrogensae (ADH) concentration of blood were measured after oral administration of ethanol. The administration of DTS20 (200-500 mg/kg) had beneficial actions toward alcohol degradation in acute alcohol treated mice model. The oral administration of DTS20 showed decreased gastric mucous membrane damage produced in ethanol treated mice. In addition, intraperitoneal administration of DTS20 showed anti-inflammatory effects in inhibition tests of vascular permeability produced by acetic acid. DTS20 also reduced the concentration of nitric oxide (NO), tumor necrosis factor (TNF)-${\alpha}$ in macrophages that were activated by LPS. These results demonstrate that DTS20 possesses potential to stimulate the alcohol degradation and inhibit the inflammatory effects in mice.

This study aims to suggest the partition ratio (Q-factor) of healthy Koreans and the comparison results of breath alcohol concentration (BAC) measurements using two methods (photoacoustic and electrochemical methods) for developing breath alcohol ignition interlock devices (BAIIDs). Given the relationship between BACs and BrACs and the Q-factor, the alcohol metabolism of healthy Koreans (96 males and 91 females) is revealed for understanding the digestion of alcohol and surveying the fundamental data of alcohol-related problems, CO₂ concentrations vs. alcohol concentrations, and the performance of alcohol sensors in the marketplace. The average Q-factor of healthy Korean males and females are 1,913 (95% confidence interval from 1,889-1,937) and 1,991 (95% confidence interval from 1,945-2,036). Photoacoustic measurements could be applied to predict the BACs of drinkers, which is confirmed by the Bland-Altman plots presented in this study. The biases based on the partition ratios (Q=1,913 and Q=1,991) in the Bland-Altman plots were -0.0004% (95% CI from -0.0011 to +0.0003% for males) and -0.0017% (95% CI from -0.020 to +0.017% for females).

Drunk driving defines a driver as unable to drive a vehicle safely due to drinking. To crack down on drunk driving, alcohol concentration evaluates through breathing and crack down on drinking using S-shaped courses. A method for assessing drunk driving without using BAC or BrAC is measurement via biosignal. Depending on the individual specificity of drinking, alcohol evaluation studies through various biosignals need to be conducted. In this study, we measure biosignals that are related to alcohol concentration, predict BrAC through SVM, and verify the effectiveness of the S-shaped course. Participants were 8 men who have a driving license. Subjects conducted a d2 test and a scenario evaluation of driving an S-shaped course when they attained BrAC's certain criteria. We utilized SVR to predict BrAC via biosignals. Statistical analysis used a one-way Anova test. Depending on the amount of drinking, there was a tendency to increase pupil size, HR, normLF, skin conductivity, body temperature, SE, and speed, while normHF tended to decrease. There was no apparent change in the respiratory rate and TN-E. The result of the D2 test tended to increase from 0.03% and decrease from 0.08%. Measured biosignals have enabled BrAC predictions using SVR models to obtain high Figs in primary and secondary cross-validations. In this study, we were able to predict BrAC through changes in biosignals and SVMs depending on alcohol concentration and verified the effectiveness of the S-shaped course drinking control method.

The present study was conducted to investigate the effects of beverages containing fermented Akebia quinata extracts on alcoholic hangover. For this study, 25 healthy young men were recruited. All participants consumed 100 mL of water (placebo), commercial hangover beverage A or B, fermented A. quinata leaf (AQL) or fruit (AQF) extract before alcohol consumption. After 1 h, all participants consumed a bottle of Soju, Korean distilled liquor (360 mL), containing 20% alcohol. Blood was collected at 0 h, 1 h, 3 h, and 5 h after alcohol consumption. The plasma alanine transaminase (ALT) activity was highest in the placebo group. Compared with the control group, the AQL and AQF groups showed decreased ALT activity at 5 h after alcohol consumption. Plasma ethanol concentration was increased after alcohol intake and peaked at 3 h after alcohol consumption. Compared with the control group, the A group showed a higher plasma ethanol concentration at 1 h (P<0.05). At 3 h after alcohol consumption, the AQF group showed the lowest mean plasma ethanol concentration compared to the other groups; however, there were no statistical differences. After 5 h of alcohol consumption, the AQL and AQF groups showed lower plasma ethanol concentrations compared with the B group. The sensory evaluation score for the fermented A. quinata fruit extract was lower than for the commercial hangover beverages. In conclusion, the present intervention study results suggest that fermented A. quinata extracts alleviate alcoholic hangover and reduce plasma ethanol concentrations.

Alcohol consumption has numerous health consequences for the human body. For example, heavy drinking on a daily basis causes liver diseases, and certain products such as acetaldehyde produced from alcohol metabolism are more toxic than alcohol itself. Accordingly, the current study evaluated the role of Lactobacillus fermentum MG590 to enhance the removal of the toxic effect of alcohol in alcohol metabolism. The maximum activities of the alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) by L. fermentum MG590 were observed after 6 h of culture. The production of ADH and ALDH by L. fermentum MG590 was also confirmed by SDS-PAGE. Six hours after the addition of alcohol to a culture broth of L. fermentum MG590, the alcohol concentration decreased from 7.5 to 2.7％. From an in vitro evaluation based on hepatocytes, the viability of hepatocytes in a medium containing alcohol and the cytosol of L. fermentum MG590 was higher than that in a medium containing only alcohol. From an in vivo test using SD rats fed a 22％ alcoholic drink, the blood alcohol concentration (BAC), glutamic-oxaloacetic transaminase (GOT), and glutamic-pyruvic transaminase (GPT) in the rats fed a medium containing L. fermentum MG590 were lower than those in the rats fed a medium containing only the alcohol drink. These results demonstrate that the ADH and ALDH produced by L. fermentum MG590 play an important role in detoxicating alcohol in vivo. Therefore, a fermentation broth of L. fermentum MG590 could be used as an effective alcohol detoxification drink.
