본 연구에서는 페피노(Solanum muricatum Ait.) 과실추출액이 흰쥐의 알코올 대사에 미치는 영향을 알아보기 위하여 페피노 추출액이 알코올 투여 쥐의 혈 중 알코올과 아세트알데히드 농도, GOT와 GPT에 미치는 영향에 대하여 알아보았다. 페피노 추출액($11.4^{\circ}$ Brix) 투여 시, 혈 중 알코올농도는 대조군에 비하여 유의적으로 31.5% 감소하였으며 혈 중 아세트알데히드 농도는 유의적 차이는 없었다. 페피노 추출액을 농도별로 알코올 투여 30분 전에 투여 시, 혈 중 알코올 농도는 $1^{\circ}$ Brix 페피노 추출액 투여군이 대조군보다 56.4% 유의적으로 낮았으며, 혈 중 아세트알데히드 농도는 유의적 차이는 없었다. 혈중 알코올 농도 감소효과는 페피노 추출액 농도가 $1^{\circ}$ Brix일 때 가장 좋았다. $1^{\circ}$ Brix 페피노 추출액을 투여하여 시간 경과에 따른 혈 중 알코올 농도는 알코올 투여 1, 3, 5시간 후 대조군보다 유의적으로 각각 19.9%, 45.4%, 60.7% 감소하였다. 혈 중 아세트알데히드 농도는 알코올 투여 5시간 후, 대조군보다 약 19% 낮게 나타났다. GOT, GPT 활성은 모두 정상범위에 속해 알코올의 1회 투여로는 간 손상을 일으키지 않았다. 페피노 추출액은 알코올을 투여한 흰쥐의 혈중 알코올을 낮추어 흰쥐의 알코올 대사에 긍정적으로 영향을 미치는 것으로 사료된다.

The purpose of this work was to investigate pharmacokinetics of alcohol as a function of dose and time of administration of ethanol. The pharmacokinetics of alcohol 15 min after and before oral administration of aspartate-containing compositions to rats were also evaluated. The retention time of acetaldehyde, alcohol and isopropyl alcohol an internal standard in gas chromatogram was 3.6, 6.0 and 10.5 min, respectively. The maximum concentration of alcohol $(C_{max})$ and area under the blood concentration (AUC) were significanly increased as a function of ethanol dose in a nonlinear fashion. The significant diurnal variation of alcohol pharmacokinetics was also noted, showing fast metabolism and elimination when given orally in the night time. When APAP was given after administration alcohol (1g/kg) to rats, AUC and $C_{max}$ were increased when compared to alcohol only. However, AUC and $C_{max}$ were decreased when aspartate or standard complex compositions containing aceaminophen (APAP, 250mg). sodium L-aspartate(25 mg), dl-methionine (125 mg) and anhydrous caffeine (25 mg) was orally given by coupling malate/asparate shuttle in hepatocyte. The blood alcohol concentration profiles between aspartate and standard complex compositions were similar when given before or after administration alcohol (1g/kg) to rats. No significant difference of administration sequence was observed. However, it was noted that AUC and $C_{max}$ of standard complex compositions given before alcohol administration were significantly lower when compared with alcohol only. Based on these findings, dose, time of administration and composition of drugs to improve alcohol metabolism and elimination were considered to be important in the pharmacokinetics of alcohol. The administration sequence of drug compositions and alcohol might be also considerd.

This study was conducted to investigate the effects of oral supplementation of alanine and glutamine on alcohol metabolism. The subjects were 70 male ICR mice weighing 25-30 g. The animals were raised on standard rations artier weaning. After 24 hours of fasting, all the animals were given a peritoneal injection of 20% alcohol. Then, they were randomly divided into two groups: control and experimental. Fifteen minutes after the injection of alcohol, the mice in the experimental group wer given an oral solution of alanine(5 mM, 2 g/kg B. W) and glutamine (5 mM, 2g/kg B.W). The concentration of alcohol in the blood was measured in all the mice 20 minutes after they received the alochol, and the measurements continued every 20 minutes up to 140 minutes. The experimental group sustained lower blood alcohol levels at every 20 minute time interval compared to the control group, showing that oral supplementation of alanine and glutamine increases the rate of alcohol metabolism. Furthermore, the total amount of alcohol remaining in the blood, determined by using the Area Under the Curve (AUG) method, was lower in the group supplemented with alanine and glutamine, However, the effectiveness of alanine and glutamine in increasing the rate of alcohol metabolism, compared to the control group, diminished with time throughout the experiment. In conclusion, alanine and glutamine supplementation appears to promote alcohol metabolism shorthy after alcohol intake.

This study was conducted to evaluate the hangover relieving effect of Sanghwang mushroom mycelium extract (SME). The extract showed 1,1-diphenyl-2-picrylhydrazyl radical scavenging effect in a concentration-dependent manner and high antioxidant capacity ($56.67{\pm}1.77%$) when administered at $120{\mu}g/mL$. In addition, SME significantly increased (p < 0.005) the aldehyde dehydronase (ALDH) activity ($126.03{\pm}9.11%$) when applied at 8 or $16{\mu}L/mL$. A locomotor activity test showed that the alcohol-water treated group showed significantly decreased motor activity at 90 min post-administration. However, the alcohol-SME treated group showed a 20-fold higher motor activity than that observed in the alcohol-water treated group at 90 min post-administration. Blood was harvested from each mouse at 90 min post-administration, and both alcohol and aldehyde concentrations were measured. The alcohol-SME treated group showed significantly lower (p < 0.5) alcohol ($120.13{\pm}12.83{\mu}g/mL$) and aldehyde ($7.26{\pm}1.22{\mu}g/mL$) concentrations than the values observed in the alcohol-water treated group. These results suggest that the hangover relieving effect of SME results from increased ALDH activity, which reduces the aldehyde concentration in the blood.

Chunggansan was tested for the effects on detoxication mechanism of alcohol. Chunggansan was treated firstly into samples, and then ethanol intoxicated animal models were set with them. The administration of Chunggansan to the rats increased proportionally in alcohol dehydrogenase activities in liver in relation to the level of concentration and days of treatment. Especially, the alcohol dehydrogenase was the most active when the concentration of extract was 200mg/kg and it was 7th day. The enzyme activities of alcohol dehydrogenase and aldehyde dehydrogenase in liver highly increased in Chunggansan pre-medicating group compared to that of ethanol treated group. Also, the blood ethanol concentration in rats was considerably decreased. In conclusion, Chunggansan recovers the damage of liver due to acute alcohol intoxication by the increased enzyme activities of alcohol dehydrogenase and aldehyde dehydrogenase.

An eight-week-old male ICR mouse, which was induced with acute alcohol and sub-acute alcohol poisoning condition, was administered with bohee tea(Camelia sinensis L) extract. Under the inducement of the sub-acute alcohol poisoning condition, no considerable differences could be found in the blood alcohol concentration of the positive control group and the bohee tea group(p<0.05). The GOT activity of the three groups: bohee tea, Drink, and Alcodex decreased than that of the normal control group(9.064±4.687 unit)(p<0.05). In addition, the blood GOT activity of the dark green tea group dropped by 81.44% compared with that of the positive control group. On the other hand, the blood GTP activity of the bohee tea group decreased by 5.2% as opposed to that of the positive control and the Drink that decreased by 7.5% as opposed to that of the positive control. The hepatic ADH activity of the bohee tea increased by 22.7%, as opposed to that of the positive control group. The Drink, however, had an increase rate of 33.6%. In the case of the hepatic ALDH activity of the liver, no significant differences were ever recorded among all groups, except for the positive control group. Due to an intake of bohee tea extract, the hepatic ALDH activity decreased by 77.27% which could not be seen in the positive control group. However, Drink and A1codex had a decrease could be seen(p<0.05).
