The present stduy was undertaken to investigate the possible effect of Puffer fish skin extract (Pf) on the heptic acetaldehyde metabolism . It was obsrved that PF markedly decreased the acetaldehyde levels in blood and liver. The activity of mitochondrial aldehyde dehydrogenase (Ald DH) increased by induction of acute intoxicatiion of alcohol (5 g/kg) was further increased through pretreatment with PF for 2 weeks. When PF was given to rat fed with 25% alcohol solution instead of water for 6 weeks. the activity of Ald DH in mitochondrial fraction decreased to about 28% compared with sucrose-treated group. But after pretreatemnt of PF, the activity was restored to the normal level. By the treatment with disulfiram (300 mg/kg, once a day for 3days) was restored to the control after the pretreatment with PF. And also mitochondrial Ald DH activity in vitro was not changed. All these observations suggest that reduction of acetaldehyde levels are partly due to increase activity of mitochondrial Ald DH. Therefore, the recovery from intoxication of acetaldehyde may be enhanced by treatment with PF.

Purpose: Alcohol intoxication is frequently observed in patients with brain hemorrhage. The purpose of this study was to determine whether intoxication affects the Korean Triage and Acuity Stage (KTAS) level and the emergency medical process in emergency departments. Methods: This study was a retrospective observational study enrolled 253 brain hemorrhage patients (47 of those intoxicated) who visited the emergency medical center on public EMS ambulance from January. 1, 2017 to April, 30, 2019. Data were collected through the electronic medical record (EMR). KTAS level and time to computerized tomography (CT) were compared to evaluate whether inebriation affects care and examination processes. All data were analyzed using SPSS program. Results: Of the 47 patients intoxicated patients, 85.1% were male, and 74.5% accompanied by trauma. Initial KTAS level showed significant differences (77.2%; p=.000) when the level 3,4 was not drunk. The average time taken from triage to CT scans showed a significant difference of 24.81±23.72 (min) when the drunken state was not 58.38±56.54 (min)(p=.000). Conclusion: In patients with brain hemorrhage admitted to ED from public EMS, undertriage and delay after initial assessment were detected in inebriated patients. Careful initial evaluation and prompt medical response should be considered for patients transported by EMS.

Liver and serum rhodanese activities were determined in acute ethanol intoxicated rats with extrahepatic cholestasis induced by common bile duct ligation (CBD) to manifest the biochemical background of alcohol drinking hazard under the hepatobiliary disease. Liver cytosolic and microsomal rhodanese activities and these Vmax values in CBD ligated rats with acute ethanol intoxication were found to be decreased much more than that in CBD ligation alone. However, the difference of Km value on above hepatic enzyme was not found between the experimental groups. On the other hand, serum rhodanese activity in CBD ligated rats with acute ethanol intoxication was greater increased more than that in CBD ligation alone. These results indicate that the biosynthesis of the hepatic rhodanese decreases and the serum rhodanese activity increases in cholestasis combined with acute ethanol intoxication, reflecting damage of aggravated hapatocytic membrane. Accordingly, the resulting data supported the fact that alcoholic drinks were enzymologically harmful to the hepatobiliary disease.

The purpose of this study was to determine the effects of Puerariae flos herb-acupuncture on hippocampal neural cell proliferation. Sprague-Dawley rats were randomly assigned into 4 groups; control group, control with herb-acupuncture group, alcohol group, alcohol with herb-acupuncture group group. Control groups were received with NaCl, while alcohol intoxication groups were injected intraperitoneally with alcohol (2 g/㎏) twice per day for 3 days. Herb-acupuncture groups were injected on Zhongwan (CV 12) for 5 consecutive days. Bromo-deoxyuridine (BrdU) was injected into all animal per day for 5 days. For the detection of BrdU-positive cells in dentate gyrus of hippocampus, immunohistochemistry was performed. In alcohol group, a significant decrease in BrdU-positive cells was observed compared to control group. In alcohol with herb-acupuncture group, BruU-positive cells increased significantly compared to alcohol group. In conclusion, the present results revealed that new cell proliferation is enhanced in the dentate gyros of young Sprague-Dawley rats through Puerariae flos herb-acpuncuture in an acute alcoholic intoxication condition.

Previous research indicates that depressive symptoms and alcohol consumption are highly correlated with each other. However, there is lack of consensus on the causal relationship between depressive symptoms and alcohol use. In order to address this limitation, this paper examines causal relationship between the two variables using non-recursive structural equation modeling, controlling sociodemographic and psycho-socio-behavioral variables. Data included 14,469 community dwelling individuals who participated in Korea Welfare Panel Study in 2006. Results showed that the effects of alcohol consumption on depressive symptoms was statistically significant, whereas the effects of depressive symptoms on alcohol consumption was not. Significant portions of the effects of psycho-socio-behavioral variables on depressive symptoms were indirect through their effects on alcohol consumption. Based on the results, implications for intervention and future research were discussed.

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.

Hepatic subcellular $\alpha$-D-mannosidases activities and its Km and Vmax values were determined in chronic ethanol intoxicated rats with extrahepatic cholestasis induced by common bile duct ligation to manifest the biochemical background of alcohol drinking hazard under the hepatobiliary disease. In case of extrahepatic cholestasis, chronic ethanol intoxication in animals led to the increased activities of liver Golgi and microsomal $\alpha$-D-mannosidase as well as the Vmax values of these enzymes. However, the difference of Km values on hepatic subcellular enzymes were not found between the experimental groups. Therefore, the results indicate that the liver Golgi and microsomal $\alpha$-D-mannosidase may be more induced in chronic ethanol intoxication animals in case of cholestasis. Accordingly, the resulting data supported the fact that alcoholic drinks may led to enhancement of the hepatobiliary liver damage.

Persimmon has been known to help alcohol intoxication in Korea for a long time and is prepared as a processed food. The effect of dried persimmon snacks on alcohol metabolism was determined in vivo. Eight Korean men (25~27 years old) were administered 3.5 mL/kg of alcohol (22.5%, w/v) with or without a dried persimmon snack (2g/kg). The levels of alcohol in the blood and of acetaldehyde in the blood and the urine were determined by alcoholmeter and assay using alcohol dehydrogenase and HPLC, respectively. All subjects showed decreased levels of alcohol in blood, and six subjects showed a decrease of alcohol in urine after consumption of ethanol with dried persimmon snacks. Concentration of acetaldehyde in the blood an urine decreased significantly in three and five of the eight subjects, respectively. Reduction was more significant for alcohol than for alcohol than for acetaldehyde with administration of ethanol and dried persimmon snacks. This in vivo result suggests that dried persimmon snacks are effective in decreasing th concentration of alcohol after alcohol intake.

The influence of Panax ginseng on alcohol-induced hyperuricemia were observed. Changes of uric acid blood levels and hepatic xanthine oxidase activities were studied by means of treating alcohol intoxication with ginseng. It was found that a single dose (4 mg/Kg) of ginseng saponin administered intraperitoneally significantly inhibits the hepatic xanthine oxidase activities and decrease urate blood levels in ethanol-induced hyperuricemic mice. It was also observed that there were some difference in pharmacological aspect between Panax ginseng and allopurinol which is a potent inhibitor of xanthine oxidase from any sources.
