간은 우리 몸에 필요한 단백질과 여러 가지 영양소를 만들고 저장하며 건강에 해로운 물질을 해독하는 일을 한다. 이러한 간에 이상이 생기면 간장질환이 발생하게 되며, 간장질환은 급격히 발생하는 A형 간염에서부터 6개월 이상 지속되는 만성간염, 지방간, 간경변, 간암까지 매우 다양하다. 이 중 대표적인 질환으로 지방간을 들 수 있다. 연말 각종 모임이나 회식, 송년회 등 잦은 술자리로 인한 문제는 과음으로 오는 지방간이다. 지방간은 과음으로 인한 알코올성 지방간과 비만, 당뇨, 고지혈증 등으로 인한 비알코올성 지방간이 있다.

지방간이라고 하면 으례 술 때문이라고 생각하기 쉽지만, 술을 거의 마시지 않는 사람이라하더라도 비만이나 당뇨병, 고지혈증 등과 같은 원인에 의해서 2차적으로 발생하는 지방간 질환도 있는데 이것을 의학적으로는 '비알코올성 지방간질환'이라고 부른다.

This study was carried out to investigate of the associations of Alcoholic & Nonalcoholic fatty liver disease(AFLD & NAFLD) with metabolic syndrome(MS) defined by IDF criteria. We conducted a cross-sectional study of 799 adult males with alcohol consumption underwent laboratory investigation(control 297, alcoholic 206, nonalcoholic 296). The ultrasound scan of the liver was performed to determine the presence and the severity of FLD. We analyzed the association between the severity of AFLD & NAFLD and MS by logistic regression analysis. The distribution of metabolic syndrome was 7.4%, 48.8%, 34.9% in control, AFLD & NAFLD. The association of blood pressure, glucose, triglycerides, obesity were risk factor in AFLD & NAFLD. According to the severity of FLD, AFLD was significantly increased with MS, Obesity, low HDL-cholesterol. MS, High triglycerides was increased significantly in NAFLD(p<0.05). The prevalence of AFLD & NAFLD was increased with increasing the number of features of metabolic syndrome. This study shows that AFLD & NAFLD was closely associated with MS and its components. The patients of AFLD & NAFLD should managed and monitored to prevent metabolic abnormalities.

이번 특집에서는 최근에 관심이 높아지면서 그 발병률이 증가하고 있는 비알코올성 지방간 질환의 발병 원인과 기전을 알아보고, 당뇨병환자에서의 지방간질환의 임상증상, 진단 등에 대해 살펴보고, 현재 응용되고 있는 치료방향에 대해서 알아보고자 한다.

Although alcohol drinking may cause fatty liver to induce hepatocytic injury, other factors lead to it. We designed this study to investigate the differences in serum iron, cardiac, and biochemical indices in men with fatty liver and the difference between alcohol drinkers (Alcohol group) and non-drinkers (Non-alcohol group). The alcohol group had higher body indices than the non-alcohol group. Systolic and diastolic blood pressure (SBP and DBP), and right and left intraocular pressure in the alcohol group were higher than those in the non-alcohol group. Hemoglobin, hematocrit, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and monocyte counts were higher in the alcohol group than in the non-alcohol group. Alanine aminotransferase, ${\gamma}$-glutamyltranspeptidase, total cholesterol, triglyceride, low-density lipoprotein cholesterol, glucose, creatinine, uric acid, iron, total iron binding capacity, and ferritin levels in the alcohol group were greater than those in the non-alcohol group. The present data reveals that alcohol-induced fatty liver has more elevated level of iron indices than in non-alcohol fatty liver as well as biochemical and cardiac indices, indicating that alcohol- induced fatty liver may cause possibility of adult diseases including cardiovascular disease and metabolic syndrome.

Nonalcoholic fatty liver disease (NAFLD) is accumulation state of fat in liver cells without excessive alcohol intake, and it has been studied that is closely related to obesity. The purpose of this study is to identify risk factors for NAFLD and may prevent or to manage risk factors. This study was in progress for six months (2011 May 1 to October 31), of the 83 people who underwent abdominal ultrasound 11 people eventually were selected. Research results was as follows : First, the decreased body weight and body mass index (BMI), and the second, a decrease of the deepening of fatty liver in ultrasound diagnosis, and the third, steady movement reduces the deepening of fatty liver regardless of calories. Thus, the implication of this research is that long-term exercise programs have positive effects in the treatment of fatty liver.

Nonalcoholic steatohepatitis (NASH) is the progressive stage of nonalcoholic fatty liver disease (NAFLD) that highly increases the risk of cirrhosis and liver cancer, and there are few therapeutic options available in the clinic. Poricoic acid (PoA), a component of Poria cocos Wolf, has a wide range of pharmacological activities; however, little is known about its effects on NASH. The preventive effects of PoA on NASH were examined in vivo and in vitro by analyzing triglyceride synthesis, inflammation and fibrosis. In the high fat and methionine-choline deficient diet (HFMCD)-induced NASH mice, PoA reduced the liver weight and the levels of alanine aminotransferase and aspartate aminotransferase compared with non-treated HFMCD group. The staining with Oil Red O and hematoxylin and eosin revealed that PoA administration reduced red staining and the size of lipid droplet. qPCR analysis showed that PoA also reduced the expression of genes related to triglyceride synthesis. Further, immunostaining with CD68 and qPCR analysis revealed that PoA reduced the staining with CD68 and the expression of inflammatory genes induced by HFMCD. Moreover, PoA reduced the staining with sirius red and antibody of α-smooth muscle actin and also reduced the expression of genes related to fibrosis. The treatment of PoA to AML12 cells reduced the increase in triglyceride amount and expression of genes associated with triglyceride synthesis, inflammation and fibrosis. Taken together, our study indicate that PoA has therapeutic effect on NASH through preventing triglyceride synthesis, inflammation and fibrosis.

Non-alcoholic fatty liver disease is the most common cause of chronic liver diseases. This study was to characterize early hepatic lipid changes in fatty liver rat model by in vivo short-echo time(TE) $^1H$-MRS(Proton - Magnetic Resonance Spectroscopy). Each the examinations were measured from liver parenchyma in rats at 0, 2, 4, 6, 8 weeks followed by high fat diet, respectively. Significant increase in lipid signals. 0.9, 1.3, 2.3, 2.8, and 5.3 ppm was found in animals with 2 weeks(p<0.01). Therefore, $^1H$-MRS is useful in detecting and characterizing various hepatic lipid alterations as early as 2 weeks for the start high fat diet.

The aim of the present study was to investigate effects of a 12-week aerobic exercise training program and a gym-ball exercise training program on body composition, aspartate aminotransferase (AST), alanine aminotransferase (ALT), adipokines, and cardiovascular risk factors in obese children with nonalcoholic fatty liver disease. The subjects were separated into two groups, an aerobic exercise group (n=10), which practiced moderate aerobic exercise training for 12 weeks, and a gym-ball exercise group (n=13), which practiced resistance exercise training for 12 weeks. The results of the analyses are as follows: Weight, body mass index, and body fat were significantly lower (p<0.01, respectively), whereas the $VO_2$ max was higher in both groups (p<0.01). Fasting glucose, insulin and HOMA-IR levels were significantly decreased in the gym-ball exercise group (p<0.05), whereas adiponectin, AST, and ALT levels were significantly increased (p<0.05, p<0.001, p<0.001, respectively) in both groups after the 12-week exercise training program. In addition, our results showed that HOMA-IR, insulin, and concentrations of C-reactive protein (CRP) were significantly lower in both groups. They demonstrate that a 12-week program of regular aerobic exercise or gym-ball exercise yields beneficial effects such as an amelioration of cardiovascular risk factors, body indices, and liver function in obese children with nonalcoholic fatty liver disease.
