This study was undertaken to investigate the effect of the levels of dietary Zn and alcohol consumption on lipid metabolism in Sprague-Dawley male rats weighing 80 to 90g for eight weeks. Ninety rats were divided into nine groups according to Zn levels and alcohol consumption such as no alcohol group[low Zn diet group(<1ppm. LZ) control Zn diet group(30ppm. CZ) high Zn diet group(60ppm, HZ)] 10% alcohol consumption group[the same Zn levels as no alcohol group LZLA, CZLA, HZLA] 20% alcohol consumption group[the same Zn levels as no alcohol group, LZHA, CZHA, HZHA] The results obtained were summarized as following : 1) In the serum total cholesterol increased with increasing dietary Zn levels but decreased with alcohol consumption. HDL-cholesterol decreased with alcohol consumption. Triglyce-ride in alcohol group was higher than no alcohol group. In alcohol group triglyceride increased with decreasing dietary Zn levels. 2) In the liver total lipid in alcohol group was higher than no alcohol group HA group showed a significant increase. Triglyceride increased with alcohol consumption. 3) In the serum and liver Zn content increased with increasing dietary Zn levels but decreased with alcohol consumption.

일반적으로 ECG(electrocardiogram)파형은 정상인의 경우에도 그 형태가 일정하지 않으며, 측정시간 및 측정인의 상태에 따라서도 파형이 변화하기 때문에 표준화된 ECG파형 검사로는 개인의 특성에 따른 정밀 진단이 어려웠다. 따라서 자동화된 개인별 맞춤형 진단을 위해서는 측정대상에 대한 사용자인식 기술이 필수적이다. 본 논문에서는 세 가지 잡음제거법을 이용하여 파형의 잡음성분을 제거하고, ECG Limb Lead III 파형의 다양한 신호간격(interval) 특성치와 미분변화량을 통한 꼭짓점 분석 등을 통하여 파형으로부터 특정인의 특징을 추출한 후 신경회로망을 이용하여 생체인식을 수행하였다. 실험은 동일한 연령대인 7명의 성인남녀를 대상으로 하였고, 재현성을 평가하기 위해서 인위적인 변화(커피, 담배, 알코올 섭취 및 스트레스)후의 ECG파형을 측정, 특정인 인식률을 실험한 결과 실험에 이용된 제한된 변동 내에서 90.9%의 인식률을 보였다.

Purpose: The purpose of this study was to investigate the recovery time and its related factors after sedative gastroscopy. Method: The subjects of this study consisted of 103 clients. The data were collected from clients who visited a health care system at S national university hospital in Seoul. The sedative gastroscopy was performed by gastrointestinal endoscopists. Patients' demographics and medical characteristics were assessed by reviewing the patients' charts. Degree of sedation and recovery were assessed by the Ramsay's sedation scale and the Aldrete score, respectively. Result: The mean recovery time was $37.8{\pm}16.9$ minutes(range, 5 to 90 minutes). Hypoxia was resent in four clients during recovery. Alcohol intake(p=0.02) and pulmonary function(p=0.003) were significant factors affecting recovery time, whereas midazolam dose and sedation level were not. Conclusion: Current alcohol intake, pulmonary function were predicting factors on recovery time.

Objectives : We investigated the relationship of the alcohol withdrawal symptoms with genetic polymorphism among alcohol dependence patients. Method : The measuring instruments used in this study were the Clinical Institute Withdrawal Assessment for Alcohol(CIWA-Ar). We analyzed DRD2 TaqI A polymorphism, dopamine transporter(DAT 1) polymorphism, and catechol-O-methyltransferase(COMT) polymorphism in 108 male alcoholics and 76 healthy controls. Results : The major findings was as follows. No significant differences for genotype distribution or allele frequency were revealed comparing controls and alcoholic patients. DRD2 Taq I : The subscale score of auditory hallucination among CIWA-Ar scale in homozygote was significantly higher than in heterozygote(OR=1.34). The total score of CIWA-Ar scale in heterozygote was significantly higher than in homozygote. DAT1 : In the subject without DAT-9 gene allele, it was significantly higher of the subscale score of sweating, anxiety among CIWA-Ar scale than in the subject with DAT-9 gene allele. And The total score of CIWA-Ar scale in the subject without DAT-9 gene allele was significantly higher than in the subject with DAT-9 gene allele. COMT : The total score of CIWA-Ar scale in heterozygote was significantly higher than in homozygote. Conclusion : Our results suggest the relationship between specific genetic factors and the withdrawal symptoms of alcohol dependent patients. As the candidate gene of the severity of alcohol withdrawal syndrome, DRD2 Taq1 gene was recommended.

To investigate the effects of garlic and medicinal plants extracts (GP) on liver function and lipid metabolism of rat administered with ethanol chronically, Sprague-Dawly male rats were fed with a basial diet (Normal), a basial diet plus ethanol (Control, 10 mL of 20% ethanol/kg b.w/day), a control diet plus 0.5% garlic and 1.0% medicinal plants extracts (GP-I), and a control diet plus 1.0% garlic and medicinal plants extracts (GP-II) for 4 weeks. Blood glucose in GP group was significantly decreased, but not significantly different between GP-I and GP-II group. Albumin content of serum was significantly increased in GP groups, while total lipid, cholesterol and triglyceride of serum were significantly decreased in GP group. Total cholesterol and triglyceride were not significantly different between GP-I and GP-II group. LDL-cholesterol in blood was decreased to 58% in GP-I group and 73% in GP-II group compared to the control group, it's contents were the lowest amounts among the normal, control and experimented groups. Lipid levels in liver of rat administered with alcohol were decreased in GP group and significantly different in GP-II group. GOT and r-GTP activities were significantly higher in control than normal group, while GPT and ALP activities were not significant in groups administered with alcohol. Activities of GOT, GPT and r-GTP were significantly lower in GP group than control group, while ALP activity was not significant in all groups. TBARS contents were not significant in serum, but it's contents in liver were significantly decreased in GP groups than control group. DPPH radical scavenging ability in serum and liver was significantly increased in GP groups. These results indicate that garlic and medicinal plants extracts were effective in improving and protecting liver disorder induced from long-term alcohol consumption.

This study examined the effects of a soybean sprouts mixture containing 1.5% Hovenia dulcis Thunb. fruit concentrate (SHM) on relieving hangovers and improving liver function in chronically alcohol-treated rats. The ampelopsin and L-asparagine contents in the SHM were 10.52, 35.19 ppm. When chronic alcohol-induced rats were treated with SHM, the body weight increased and the liver weight decreased. The serum alcohol and acetaldehyde concentrations were lowest in the SHM group, and the hepatic ADH and ALDH activities were highest in the SHM group. Chronic alcohol induction increased the activity of liver function indicator enzymes such as ALT, AST, and GGT, but the activity was decreased significantly with the SHM treatment. The triglyceride content in hepatic and serum blood samples was lowest in the SHM group. The serum total cholesterol and LDL cholesterol contents decreased in the SHM group, and the HDL cholesterol content increased. The color of the hepatic observed morphologically in the SHM group was reddish brown, and the size and number of lipid droplets in the hepatic observed pathologically decreased. The hepatic and serum lipid peroxidation content of the SHM group decreased. The hepatic and serum GSH content increased in the SHM group. Therefore, SHM can be a functional food that can help hangovers and improve liver function.

Background and Objectives : Although many studies have examined the effect of drinking on voice change, its cause and degree remain unclear. Since voice change occurs more frequently the day following drinking, rather than immediately afterwards, we examined whether the voice change was correlated with reflux laryngitis due to gastroesophageal motor disturbances. Subjects and Methods : For this study, 10 patients were selected who had neither voice change nor symptoms of reflux laryngitis at baseline (male : female=5 : 5, mean age=28 years old) They were subjected to psychoacoustic, acoustic, and aerodynamic tests and video stroboscopy at 4:00 P.M. the day before drinking (test 1), at 8:00 A.M. (test 2) and 4:00 P.M. (test 3) on the following day. On the day of drinking, the subjects had to drink more than their usual amount of Soju(Korean liquor) and were not allowed to talk much. The stroboscopy findings were quantified using the PC Belafsky score. Results : The laryngeal response to gastric reflux after drinking was compared between tests 1 and 2. In both tests, laryngeal edema and injection were observed on video stroboscopy. The psychoacoustic test detected more severe hoarseness in test 2 than in test 1. In addition, the acoustic test detected a mild increase in both jitter and shimmer. However, the differences between tests 2 and 3, which were performed when there was reduced or no gastric reflux, were not significant. Conclusions : Drinking may cause gastric reflux, which produces reversible voice change by irritating the vocal cords and larynx. Therefore, reflux laryngitis should be suspected in a patient whose voice changes markedly after drinking.

담낭용종의 잘 알려진 위험요소는 대사증후군, 연령, 이상지질혈증 등이다. 제주도는 한반도에서 가장 큰 섬으로 한국의 본토에서 약 80km 떨어져 있으며 행정구역상 제주시와 서귀포시로 나뉘어 있지만 기업들과 편의시설들, 학교들 때문에 자연스럽게 시내와 시외로 더 나누어진다. 많은 이주민들과 젊은 성인들은 상업 활동이 활발한 시내 지역에 사는 경향이 있다. 고령 성인들은 어업이나 농업에 종사하기 때문에 시외 지역에 사는 경향이 있다. 고령의 성인들은 전통적인 식이를 유지하고 있고, 그들 중 다수는 힘든 노동으로 인해서 고위험 알코올 음주자의 비율이 높다. 이러한 요인들로 인해 두 지역간의 담낭용종 유병률에도 차이가 있을 것이다. 따라서 이 연구의 목적은 제주도 두 지역간에 담낭용종의 유병률을 알아보고 그 유병률과 관련된 다양한 요인들을 비교해 보고자 하는 것이다. 이 연구는 2009년 1월부터 2019년 12월까지 제주대학교병원 단일 건강검진센터에서 건강검진을 시행한 21,734명을 대상으로 하였다. 시내 지역과 시외 지역 거주민들의 담낭용종 유병률은 각각 10.1%와 8,7% (P = 0.006)로 의미있게 차이가 있었다. 평균 총콜레스테롤 수치가 시내 지역 거주민들에서 시외 지역 거주민들보다 높았고, 음주와 관련된 평균 알카라인 인산분해효소와 감마-글루타밀전이효소 수치들과 평균연령은 시외 지역 거주민들이 시내 지역 거주민들보다 더 높았다. 나이, 알코올 섭취와 평균 콜레스테롤 수치가 이러한 두 지역 간에 담낭용종 유병률의 차이를 만들었을 것이다.

This study was carried out to examine the effects of vitamin E on chronic gastric ulcer induced by alcohol treatment in rats. Chronic gastric ulcer model was established by oral administration of 70% ethanol at one time and supply of 15% ethanol for additional 7 days. Male Sprague-Dawley rats, approximately 200 g, were fasted for 24 hours and orally gavaged with 1 mL of 70% ethanol for the induction of acute ulcer. A supply of 15% ethanol dissolved in distilled water for 7 days were followed to maintain chronic gastric ulcer. Acute ulcer group was sacrificed at 3 hours after oral administration of 1 mL of 70% ethanol. Chronic groups were divided into three groups according to vitamin E levels; low-vitamin E (LVE, 0 mg/mL oil/day), normalvitamin E (NVE, 1 mg/mL oil/day) and high-vitamin E (HVE, 10 mg/mL oil/day). These groups were fed vitamin E free diets which were made of vitamin E free vitamin mix followed AIN-93M pattern for 7 days. Histological findings of congestion, hemorrhage and necrosis in gastric tissue were shown severely in acute ulcer group and LVE group of chronic ulcer groups. The concentration of gastrin in serum was significantly higher in LVE group. The content of histamine in stomach was lower in acute ulcer group but there was no significant difference among the chronic groups regardless of vitamin E levels. Content of malondialdehyde (MDA) in gastric tissue was higher in HVE group and activities of antioxidant enzyme, glutathione peroxidase (GPx) and catalase, were lower in HVE group. Myeloperoxidase (MPO) activities as a marker of neutrophils infiltration was significantly higher in LVE group. These results suggested that vitamin E supplementation has positive effects on healing of alcohol-induced chronic gastric ulcer through alleviation of gastric tissue injuries and reduction of the MPO activity in gastric tissue and gastrin in serum.
