  • Hepatic cirrhosis is a common response to chronic liver injury from many causes and is one of the most common cause of all deaths. This study was carried out to compare experimental hepatic cirrhosis in rats to understand this disease and to apply for the pharmacokinetics in disease state. Following three kinds of experimental models were induced; 1) Bile duct ligation/scission (BDL/S), 2) N, N-dimethylnitrosamine(DMN), 3) Carbon tetrachloride. The hepatic cirrhosis was characterized by examing the liver/body weight ratio, serum biochemical values, hydroxyproline content in liver and histopathological lesions in cirrhotic rat liver. The results are as follows : (1) In BDL/S, the liver was enlarged to 250% of normal liver. In contrast the liver was shrinked to 48% and 78% of the normal liver in DMN and carbon tetrachloride, respectively. (2) In carbon tetrachloride and BDL/S, the serum ALT, AST, ALP and total bilirubin levels were significantly increased to 200~300% of normal level, while ALT and total bilirubin levels were significantly increased in DMN group. (3) Hydroxyproline content in cirrhotic rat liver was significantly 200~500% higher than that of normal liver. (4) Nodular formation with fibrosis was observed in BDL/S, DMN, carbon tetrachloride induced cirrhotic rat liver.

  • Nonalcoholic fatty liver disease (NAFLD) is recognized one of the leading metabolic diseases globally, and the younger age population with the disease is rapidly growing, especially in developed countries. Since there has been no approved medicine, losing weight is known to be the only best remedy to control or reverse the disease. Recently, the field of microbiome has attracted much attention to offer more practical choices for patients. Here, we provide experimental evidence that Streptococcus thermophilus LM1012 (LM1012), a safe probiotic strain, is effective for improving NAFLD indexes. In the methionine-choline deficient (MCD) diet induced C57BL/6 mouse model, administration of LM1012 promoted marked reductions of aspartate transaminase (23.8%), total bilirubin (27.8%), hydroxycholesterol (64.2%), triglyceride (29.7%) and IL-1β (68.3%) compared to the MCD diet alone group. Also, the histopathological data imply that LM1012 inhibited fat accumulation and inflammation in the liver, which are the key biomarkers for progression of the disease. Together, these findings suggest that human consumption of LM1012 as a healthy nutritional supplement, may be helpful in reducing the risk of liver damages in NAFLD patients.

  • Purpose: This study aimed to investigate LDQOL (Liver Disease Quality of Life) and its related factors of patients with Hepatitis B. Method: A cross-sectional descriptive study. The LDQOL was formally translated to Korean and reliability was examined. One hundred thirty eight patients following gastroenterology outpatient clinic of S. hospital in Seoul, Korea participated. Results: The mean age of the patients was 45.43 years and 87.7% were men. The mean score of LDQOL was 77.34, and mean scores of subscale were followed; symptom of liver disease (SxLD) (82.12), effect of liver disease (ELD) (25.50), concentration (Conc) (84.47), memory (Mem) (83.24), health discomfort, (HD) (75.18), sexual function (SFun) (75.71), sexual problem (SProb) (84.70), Loneliness (85.50), Hopeless (67.43), and stigma of liver disease (SLD) (91.64). Women had a lower LDQOL score for Loneliness (p=.034), and over 45 year-old patients had a lower LDQOL overall score (p=.000). Patients who were HBV carriers, or who had Chronic Hepatitis B or Liver Cirrhosis reported lower QOL respectively(p=.032). Conclusion: Although the liver disease itself seemed to be stable, patients with HBV experienced poor QOL in ELD, SProb, SFun, and Hopeless. Therefore nursing interventions in these aspects are needed.

  • Semisulospira libertine (SL) has been used as a folk medicine for quenching a thirst, hepatic fever and inflammation in oriental countries. Although SL has been anecdotally ascertained to ameliorate the hepatic diseases, there are no sufficient experimental evidences. The purpose of this study was to examine the effect of Bitam-S, in which SL is a main component, on non-alcoholic fatty liver disease manifested in C57BL/6J ob/ob mice. At 6 week old, the ob/ob mice were randomly divided into four groups; control and three treatment groups. The control mice was to receive a regular diet, and the treatment groups were fed a regular diet with either 250mg/kg, 500mg/kg of Bitam-S (BS250 and BS500) or 300mg/kg of metformin (MT300) for a 8-week period. Bitam-S exerted beneficial effects on lipid homeostasis in ob/ob mice that are not necessarily due to its ability to decrease food intake but its specific effects on hepatic lipogenesis related genes (SREBP1a, FAS and SCD-1). The combined effects of Bitam-S to reduce body weight and lipogenic gene expressions, and reduce the deposition of triglyceride in the liver are indicative of a marked improvement in obesity-related non-alcoholic fatty liver disease. Taken together, Bitam-S has potential as a treatment agent for non-alcoholic fatty liver disease and deserves clinical trial in the near future.

  • Background: Calprotectin in feces seems to be a more sensitive marker for gastrointestinal (GI) cancers than fecal occult blood, but its specificity may be too low for screening average risk populations. This study aims at evaluating the diagnostic value of fecal calprotectin as a screening biomarker for GI malignancies. Materials and Methods: In a case-control study, 100 patients with GI malignancies (50 patients with colorectal cancer and 50 patients with gastric cancer) and 50 controls were recruited in Tabriz Imam Reza and Sina hospitals during a 24-month period. One to two weeks after the last endoscopy/colonoscopy, fecal specimens were collected by the patients and examined by ELISA method for quantitative measurement of calprotectin content. The results were compared between the three groups. Results: The mean fecal calprotectin level was $109.1{\pm}105.3$ (2.3-454.3, median:74), $241.1{\pm}205.2$ (3.4-610.0, median:19.3) and $45.9{\pm}55.1{\mu}g/g$ (1.3-257.1, median:19.3) in gastric cancer, colorectal cancer and control group, respectively, the differences being significant (p<0.001) and remaining after adjustment for age. The optimal cut-off point for fecal calprotectin was ${\geq}75.8{\mu}g/g$ for distinguishing colorectal cancer from normal cases (sensitivity and specificity of 80% and 84%, respectively). This value was ${\geq}41.9{\mu}g/g$ for distinguishing gastric cancer from normal cases (sensitivity and specificity of 62%). Conclusions: Our results revealed that fecal calprotectin might be a useful and non-invasive biomarker for distinguishing colorectal cancer from non-malignant GI conditions. However, due to low sensitivity and specificity, this biomarker may not help physicians distinguishing gastric cancer cases from healthy subjects.

  • Purpose: The incidence of non-alcoholic fatty liver disease (NAFLD) in children is gradually increasing. The aim of this study was to investigate the use of serum adiponectin and soluble adiponectin receptor 2 (soluble Adipo R2) levels for the diagnosis of fatty liver disease in obese and overweight children. Methods: The study included 51 obese and overweight children between the ages of 6 and 18 years diagnosed with NAFLD using ultrasonography and 20 children without fatty liver disease. Patients whose alanine transaminase level was two times higher than normal (${\geq}80U/L$) were included in the non-alcoholic steatohepatitis (NASH) group. Results: NASH was observed in 11 (21.6%) of the patients with NAFLD. The incidence of obesity was higher in patients with NASH (80% and 45%, p=0.021). While the adiponectin levels were similar in patients with NAFLD and those without, they were below the normal level in the whole study group. Adiponectin and soluble Adipo R2 levels of patients with NASH were lower than those in patients without NASH; however, this difference was not statistically significant (p=0.064 and p=0.463). Soluble Adipo R2 levels in obese patients with NAFLD were higher than those in obese children without NAFLD (p<0.001). Conclusion: Soluble adiponectin receptor 2 level is a noninvasive marker that can be used for the diagnosis of NAFLD in obese children.

  • Liver cirrhosis (LC) is defined as comprising diffuse fibrosis and regenerating nodules of the liver. The biochemical and anatomical dysfunction in LC results from both reduced liver cell number and portal vascular derangement. Although several studies have investigated dysregulated genes in cirrhotic nodules, little is known about the genes implicated in the pathophysiologic change of LC or about their relationship with the degree of decompensation. Here, we applied cDNA microarray analysis using 38 HBsAg-positive LC specimens to identify the genes dysregulated in HBV-associated LC and to evaluate their relation to disease severity. Among 1063 known cancer- and apoptosis-related genes, we identified 104 genes that were significantly up- (44) or down- (60) regulated in LC. Interestingly, this subset of 104 genes was characteristically correlated with the degree of decompensation, called the Pugh-Child classification (20 Pugh-Child A, 10 Pugh-Child B, and 8 Pugh-Child C). Patient samples from Pugh-Child C exhibited a distinct pattern of gene expression relative to those of Pugh-Child A and B. Especially in Pugh-Child C, genes encoding hepatic proteins and metabolizing enzymes were significantly down-regulated, while genes encoding various molecules related to cell replication were up-regulated. Our results suggest that subsets of genes in liver cells correspond to the pathophysiologic change of LC according to disease severity and possibly to hepatocarcinogenesis.

  • 현대사회에 있어서 질병은 매우 다양하게 발견되고 있다. 또한 한번 발병하면 아니면 적절한 검진시기를 놓쳐 돌이킬 수 없는 상황을 접하게 되는 경우가 종종 있다. 사회가 발전하면서 과도한 비즈니스와 음주 흡연 등으로 우리의 간은 매우 피곤한 상태에 놓이게 되며 질병 발생율도 매우 높다. 여러 질병 중 특히 간에 관련된 질병은 회복이 불가하여 장기이식수술에 의존하는 편이다. 이와 관련하여 본 연구는 MDCT로 얻어진 영상을 3차원 영상 기법으로 간의 형상을 렌더링 하여 체적을 구하고 간 이식 수술시 혈관과의 분리 작업을 통해 절개 라인을 결정할 수 있도록 미리 시물레이션 할 수 있는 영상처리 기법을 개발하고자 간 영역 자동 추출 알고리즘을 적용하여 시물레이션 한 결과 수술을 용이하게 집도할 수 있도록 새로운 장을 열게 되었다.

  • Objectives : This study was aimed to investigate current status researches and to provide source in setting development strategy on Liver-tonification acupuncture(LTA) and Liver-sedation acupuncture(LSA). Methods : We searched databases of Pubmed, KISS, OASIS, Google scholar and CNKI up to February 2017. We included articles that using LTA or LSA as main treatment, using the partial acupoints combination of LTA or LSA, or using each acupoint of LTA or LSA. We analyzed disease, details of acupuncture and control treatment and clinical outcomes from included studies. Results and Conclusions : Among the included clinical studies, case report was the most used methodology. LTA used to treat obesity, myopia, bartholinitis, tinnitus, hiccup and sleep disorder, prostate cancer and tremor. LSA used to treat panic disorder, gastroesophageal reflux disease and irritable bowl syndrome, herpes zoster and neuralgia. Obesity and tremor were the most studied diseases using LTA or LSA. Amyotrophic lateral sclerosis was the only disease which LTA or LSA have no therapeutic effect. Each acupoints was not used as a meaning of Saam acupuncture but as affiliated meridian acupoint. Since animal researches were not fully conducted, mechanism of LTA and LSA was hard to be proved. Thus, more clinical studies and basic animal research are needed.

  • Purpose: The purposes of this study were to examine self-efficacy, severity, social support, and self-care compliance of patients with liver cirrhosis and to identify the factors that affect their self-care compliance. Methods: A total of 160 outpatients with liver cirrhosis visiting the gastroenterology clinic at an university hospital located in Busan were enrolled in this study. Data were collected via self-report questionnaires including self-efficacy, severity of disease, social support, and self-care compliance measures. The collected data were analyzed using t-test, ANOVA, $Scheff\acute{e}-test$, Pearson correlation coefficients, and multiple linear regression analysis. Results: The factors affecting self-care compliance were self-efficacy, severity of disease, age, and sex. These factors explained 28.4% of the variance in self-care compliance of patients with liver cirrhosis. Conclusion: Therefore, nursing interventions that enhance patients' self-efficacy are needed to promote self-care compliance in patients with liver cirrhosis. In addition, patients must be taught of the importance of self-care compliance so that even young patients and those with relatively mild disease. That would also be motivated to comply with self-care instructions.
