목 적: 소아비만의 중요한 합병증 중 하나인 지방간을 진단함에 있어 ALT치와 CT 및 간생검 소견간의 상관관계를 살펴봄으로써, 선별검사로서 ALT치의 유용성과 확진검사로서 CT 및 간생검의 필요성을 알아보고자 한다. 대상 및 방법: 1990년 3월부터 1997년 12월까지 서울적십자병원 소아과에 내원하여 단순비만으로 진단 받은 78명 중 지방간 진단을 위해 CT를 실시한 26명을 대상으로 하였으며, 생화학검사 중 지방간의 선별검사로서 보다 특이성이 높은 ALT치가 지나치게 높거나 비만도가 심한 비만아들 중 15례에서 간생검을 실시하였다. 이들을 ALT치에 따라 3개 군으로 분류하고 각 군별로 신체계측지수, CT 및 간생검상 지방침착도 간의 상관관계를 비교 분석하였다. 결 과: 1) ALT치와 신체계측지수간의 상관관계: 대상 비만아 26례 중 ALT치는 17례(63.4%)에서 이상 상승(>30 IU/L)되었으나, ALT치의 상승과 신체계측지수들(비만도, RI, BMI, 체지방률) 간에는 유의한 상관관계가 없었다(p>0.05) 2) CT상 지방침착도와 ALT치 및 신체계측지수 간의 상관관계: 26례 중 13례(50%)에서 CT상 정상이었고, 나머지 13례는 정도의 차이는 있으나 모두 간음영이 증가된 지방간 소견을 보였다. CT상 지방간의 정도와 ALT치의 상승간에는 유의한 상관관계가 있었으나(p=0.01), 신체계측지수와는 유의한 상관관계가 없었다(p>0.05). 3) 간 생검상 지방간의 정도와 비만도, ALT치와의 상관관계: 26례 중 15례에서 간 생검을 실시한 결과, 1례에서 정상이었고 나머지 14례에서 모두 지방간 소견을 보였다. 그러나 간 생검상 정상인 1례는 고도비만이었으나 ALT치는 정상치였고, 중등도의 지방간 소견 보인 3례 중 1례는 고도비만이었음에도 ALT치는 정상이었으며 2례는 ALT치가 정상이거나 약간 증가하였으며, 심한 지방간 소견 보인 9례 중 1례는 경한 비만이었으나 ALT는 158 IU/L로 심한 상승을 보였다. 간 생검상 지방간인 14례를 지방침착도에 따라 3개 군으로 분류하여 비만도와 ALT치를 비교분석한 결과 비만도와 간 생검 소견간에는 유의한 차이가 없었으나(p>0.05), ALT치와 간 생검상 지방간의 정도간에는 유의한 차이가 있었다(p=0.01). 4) CT와 간 생검 소견간의 상관관계: 26례 중 15례에서 CT와 간 생검 모두를 시행한 결과, CT상 6례는 정상이었고, CT상 지방간 소견 보인 9례에서는 간의 지방침착도에 따른 음영의 변화를 기준으로 한 CT소견과 간 생검상 지방침착도간에 유의한 상관관계를 보였다(r=0.6094). 결 론: 최근 소아비만이 급증 추세에 있고 그에 따른 여러 가지 합병증들은 물론 성인비만으로 이행될 수 있으므로 학교보건 등을 통해 경각심을 높이도록 해야 하며, 특히 비만에 따른 지방간을 진단하기 위한 선별검사인 ALT치 등 생화학적인 간 기능 검사로는 간 손상 정도를 평가할 수 없기 때문에 보다 저비용이며 비침습적인 초음파검사를 적극 활용토록 하고 선별검사 등으로 선정된 고위험군에 대해서는 간 생검을 통해 간 손상 정도를 정확히 평가하고 지속적으로 추적 관리해야 할 것이다.

Objectives : Alcoholic fatty liver is an early and reversible consequence of excessive alcohol consumption. The initial hepatocyte cell death stimulates subsequent inflammatory responses, leading to further liver injury and fibrosis. The objective of this study is to investigate the effects of Injinsaryung-san extract on the alcoholic fatty liver by chronic EtOH administration. Method : Male Sprague Dawley rats were used in this study. All animals were randomly divided into Normal group, treated with saline (n=10); EtOH group, treated with ethanol (n=10); EtOH+IS group, treated with ethanol+Injinsaryung-san extract (n=10). For oral administration of ethanol in Control and Sample group, the ethanol was dissolved in distilled water in concentrations of 25%(v/v). Throughout the experiment of 8 week, the rats were allowed free access to water and standard chow. Sample group were administrated by Injinsaryung-san extract daily for 8 weeks. Results : The levels of hepatic marker such as aspartate aminotransferase and alanine aminotransferase were altered. Histopathological changes were reduced and the expression of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) was markedly attenuated by Injinsaryung-san extract. Conclusion : These data suggest that Injinsaryung-san extract could be effective in protecting the liver from alcoholic fatty liver. The hepatoprotective mechanisms of Injinsaryung-san may be related to attenuation of $TNF-{\alpha}$ protein, as well as to the inhibition of inflammatory response in the liver. Therefore, Injinsaryung-san can be a candidate to protect against alcoholic fatty liver.

Purpose: The rising prevalence of childhood obesity in the past decades has caused non-alcoholic fatty liver disease (NAFLD) to become the most common cause of pediatric chronic liver disease worldwide. This study was aimed at determining the effect of vitamin D (Vit D) on ultrasonography and laboratory indices of NAFLD and some blood biochemical indicators in children. Methods: In this interventional study liver ultrasonography was performed in 200 children with overweight and obesity. A 108 had fatty liver among which 101 were randomly divided into two groups of study (n=51) and control (n=50). The study group was treated with Vit D, 50000 U once a week whereas the control group received placebo with the same dose and package, both for 12 weeks. At the end of the intervention lab tests and ultrasound study was performed once again to evaluate the response to treatment. Results: It was found out that Vit D supplementation improved the fatty liver grade in the study group. The mean changes in hemoglobin (Hb), uric acid, highdensity lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), insulin, albumin and alanine aminotransferase (ALT) was significantly higher in the study group compared to controls (p<0.05). After the intervention and means adjustment, a significant difference was obtained in HDL-C, insulin, LDL-C and homeostasis model assessment of insulin resistance (HOMA-IR) between the two groups. Conclusion: Vit D supplementation in addition to improving the fatty liver grade in ultrasonography and increasing the blood Vit D level, increases the HDL and Hb level besides decreasing uric acid, LDL, HOMA-IR, insulin and ALT levels.

The purpose of this study is to investigate dietary factors which influence the conditions of Korean fatty liver patients. The subjects were 83 fatty liver patients living in city, ages of 10 to 60 yrs old, and they were the same patients studied 9 months ago in previous study. The patients were groupsed into 3 groups(improved, similar, worsened groups) according to the changes in disease condition. Nutrient and alcohol intakes and health status were investigated. In improved group, the patients tended to lose weight, the number of exercising patients was increased, the consumptions of calorie, carbohydrate, calcium, phosphorus were decreased. And alcohol intake was decreased markedly and serum total amino acids(AA), EAA, NEAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios were increased. In worsened group, patients tended to gain weight, the number of exercising patients decreased, the consumptions of calorie, protein, carbohydrate, calcium, phosphorus and niacin decreased but vitamin. A intake increased. And also, in this group, alcohol intake of male patients decreased and that of female slightly increased, and serum EAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios, and total fatty acid contents increased and total AA and NEAA contents decreased. In conclusion, it is desirable to reduced weight, stress, alcohol, salt and animal fat consumptions, and to exercise, and to take adequate amount and quality of protein to improve conditions of fatty liver patients.

Complete oxidation of fatty acid in the liver of ketotic cows was investigated. Serum non-esterified fatty acid (NEFA), beta-hydroxybutyric acid (BHBA) and glucose concentrations were measured using biochemical techniques. Carnitine palmitoyl transferase II (CPT II), 3-hydroxy acyl-CoA dehydrogenase (HAD) and oxaloacetic acid (OAA) concentrations in the liver were detected by ELISA. Serum glucose was lower in ketotic cows than controls (p<0.05). Serum BHBA and NEFA concentrations were higher in ketotic cows than controls (p<0.05). OAA, CPT II, and HAD contents in the liver of ketotic cows were lower than in controls (p<0.05). There were negative correlations between serum NEFA concentration and OAA, CPT II and HAD, but no correlation between serum BHBA concentration and capacity for complete oxidation of fatty acid. Overall, the capacity for complete fatty acid oxidation in the liver of ketotic cows might have been decreased. High serum NEFA concentrations may be unfavorable factors for the pathway of complete oxidation of fatty acid in the liver.

Chronic alcohol consumption causes alcoholic liver disease, which is associated with the initiation of dysregulated lipid metabolism. Recent evidences suggest that dysregulated cholesterol metabolism plays an important role in the pathogenesis of alcoholic fatty liver disease. Ecklonia stolonifera (ES), a perennial brown marine alga that belongs to the family Laminariaceae, is rich in phlorotannins. Many studies have indicated that ES has extensive pharmacological effects, such as antioxidative, hepatoprotective, and antiinflammatory effects. However, only a few studies have investigated the protective effect of ES in alcoholic fatty liver. Male Sprague-Dawley rats were randomly divided into normal diet (ND) (fed a normal diet for 10 weeks) and ethanol diet (ED) groups. Rats in the ED group were fed a Lieber-DeCarli liquid diet (containing 5% ethanol) for 10 weeks and administered ES extract (50, 100, or 200 mg/kg/day), silymarin (100 mg/kg/day), or no treatment for 4 weeks. Each treatment group comprised of eight rats. The supplementation with ES resulted in decreased serum levels of triglycerides (TGs), total cholesterol, alanine aminotransferase, and aspartate aminotransferase. In addition, there were decreases in hepatic lipid and malondialdehyde levels. Changes in liver histology, as analyzed by Oil Red O staining, showed that the ES treatment suppressed adipogenesis. In addition, the ES treatment increased the expression of fatty acid oxidation-related genes (e.g., PPAR-${\alpha}$ and CPT-1) but decreased the expression of SREBP 1, which is a TG synthesis-related gene. These results suggest that ES extract may be useful in preventing fatty acid oxidation and reducing lipogenesis in ethanol-induced fatty liver.

This study was performed to investigate the effect of dietary intakes and nutritional status for fatty liver male patients with fatty livers. General characteristics, nutritional knowledge, and dietary intakes were obtained from fatty liver male patients aged 20-60yr living in Seoul and Kyunggi province by individual interview and blood samples. The Results were as follows : the mean age of the subjects was 39yrs. Old and over half the subjects were overweight. Although nutritional knowledge, recognition, and accuracy scores were good, these did not affect the subject's health. The average alcohol intake of subjects was 79.8g/day and the drinking duration was 5-40yrs(average : 17yrs). The subjects drank alcohol over 4tiles/week and preferred Soju. Most side dishes taken with alcohol drinking by the subjects were foods from animal sources. Half of the subjects also drank alcohol the next day for breakfast as a hangover-chaser. The reasons for drinking were due to social relationships and by habit. Vitamin D and folate were lower than the RDA for Koreans, and other nutrient amounts were higher than the RDA. The amounts of aspartate amino-transferase(AST), Alanine amino-transferase(ALT), ${\gamma}$-glutamyl transpeptidase(${\gamma}$-GTP), Triglyceride(TG) for the subjects were higher. In conclusion, fatty liver patients drank excessively and frequently. It seems that heavy alcohol drinking is more prone to overweight or obese people and contributes to fatty livers. Therefore, the subjects need to be taken effectively educated about alcohol-induced liver damage and the importance of a balanced diet for on healthy liver.
