Objectives : Ulcerative colitis is a chronic relapsing inflammatory disease in the gastrointestinal tract. We investigated whether Aurantii fructus immaturus (AFI) pharmacopuncture has antioxidative and anti-inflammatory effects. Methods : in vitro experiments, 1,1-diphenyl-2-picryl hydrazyl (DPPH) free radical scavenging activity, superoxide dismutase (SOD) activity, prevention on $H_2O_2$-induced cell death in RAW264.7 cell line, DNA fragmentation, and cyclooxygenase-2 mRNA expression induced by lipopolysaccharide (LPS), were analyzed to investigate antioxidative and anti-inflammatory effect of AFI pharmacopuncture. in vivo experiment, a murine model of dextran sulfate sodium (DSS)-induced colitis was used to examine the effect of AFI pharmacopuncture on CV12 at different doses of 5 ${\mu}l$, 0.5 ${\mu}l$, 0.05 ${\mu}l$ for 10 days. Body weight, colon length and macroscopic features were investigated. Results : AFI pharmacopuncture showed DPPH free radical scavenging and SOD active effects in a dose-dependent manner. AFI pharmacopuncture showed a protective effect against $H_2O_2$-induced cell injury and also attenuated LPS-induced COX-2 mRNA expression. In a DSS- induced colitis murine model, however, AFI pharmacopuncture at CV12 had no anti-inflammatory effects. Conclusions : The present results suggest that AFI pharmacopuncture extract may have anti- inflammatory and antioxidative effects in vivo test, but further research on the underlying mechanism is required.

Background: Red ginseng (RG) alleviates psychiatric disorders. Fermented red ginseng (fRG) alleviates stress-induced gut inflammation. Gut dysbiosis causes psychiatric disorders with gut inflammation. To understand the gut microbiota-mediated action mechanism of RG and fRG against anxiety/depression (AD), we investigated the effects of RG, fRG, ginsenoside Rd, and 20(S)-β-D-glucopyranosyl protopanaxadiol (CK) on gut microbiota dysbiosis-induced AD and colitis in mice. Methods: Mice with AD and colitis were prepared by exposing to immobilization stress (IS) or transplanting the feces of patients with ulcerative colitis and depression (UCDF). AD-like behaviors were measured in the elevated plus maze, light/dark transition, forced swimming, and tail suspension tests. Results: Oral gavage of UCDF increased AD-like behaviors and induced neuroinflammation, gastrointestinal inflammation, and gut microbiota fluctuation in mice. Oral administration of fRG or RG treatment reduced UCDF-induced AD-like behaviors, hippocampal and hypothalamic IL-6 expression, and blood corticosterone level, whereas UCDF-suppressed hippocampal BDNF⁺NeuN⁺ cell population and dopamine and hypothalamic serotonin levels increased. Furthermore, their treatments suppressed UCDF-induced colonic inflammation and partially restored UCDF-induced gut microbiota fluctuation. Oral administration of fRG, RG, Rd, or CK also decreased IS-induced AD-like behaviors, blood IL-6 and corticosterone and colonic IL-6 and TNF-α levels, and gut dysbiosis, while IS-suppressed hypothalamic dopamine and serotonin levels increased. Conclusion: Oral gavage of UCDF caused AD, neuroinflammation, and gastrointestinal inflammation in mice. fRG mitigated AD and colitis in UCDF-exposed mice by the regulation of the microbiota-gut-brain axis and IS-exposed mice by the regulation of the hypothalamic-pituitary-adrenal axis.

Crohn ' s disease (CD)와 ulcerative colitis (UC)의 원인은 아직 확실하지 않다. 확립된 연구보고는 없으나 여러 가지 세균이나 바이러스가 원인일수도 있고, 장내세균이 증강인자일수도 있다. 또한, 서양식 식사도 장 점막의 상태와 점막투과성에 영향을 미치기 때문에 역시 증강인자라고 할 수 있다. 각가지의 생활습관도 inflammatory bowel disease (IBD) 발병에 영향을 미치는 요인으로 알려져 있지만, 이들에 대한 다 기능성인자를 규명하는 것은 아직 많은 기초적 연구가 필요하다.

The incidence of inflammatory bowel disease is increasing rapidly in Korea and one quarter of the new patients present in childhood. Crohn's disease and ulcerative colitis are incurable conditions associated with significant morbidity, therefore the focus of treatment in children should be to reduce or eliminate symptoms, optimize nutritional status and growth, prevent complications. This review will deal with the evidence supporting the treatments currently used in children with inflammatory bowel disease.

Purpose: Ulcerative colitis is a common inflammatory bowel disease. Prolonged colitis can be a risk factor for the development of colorectal cancer. Mulberry twig (MT, Sangzhi), a dry branch of Morus alba L., which is widely distributed throughout East Asia, has been shown to have anti-inflammatory activities in the cells. However, the effects of MT extracts on colitis in in vivo are limited. Therefore, in this study, we investigated the anti-inflammatory effects of MT extracts in the dextran sulfate sodium (DSS)-induced mouse colitis model. Methods: Six week-old, male ICR mice were divided into 3 groups: Control (n = 5), DSS (n = 7), and DSS+MT (n = 7) groups. Mice in the DSS and DSS+MT groups were administrated 3% DSS in drinking water for 5 days to induce colitis. At the same time, water extracts of MT (5 g/kg body weight/day) were orally administered to mice in the DSS+MT groups for 5 days. Results: The MT extracts significantly reduced the clinical and pathological characteristics of colitis. Disease activity index, mucosal thickness, and colonocyte proliferation were significantly reduced in the DSS+MT group compared with the DSS group. Furthermore, MT administration reduced the levels of plasma $TNF-{\alpha}$, IL-6, and the colonic myeloperoxidase activity as well as mRNA expression of $TNF-{\alpha}$, IL-6, Cox-2, and iNOS. Conclusion: Taken together, these results suggest that MT water extracts have potent anti-colitis activities in the mouse colitis model.

Purpose: Primary sclerosing cholangitis (PSC) is a rare condition that can be associated with inflammatory bowel disease (IBD). The aim of this study was to evaluate PSC and its association with IBD in children. Methods: We retrospectively enrolled 13 pediatric patients (<18 years) with PSC treated at Asan Medical Center between June 1989 and December 2013. Clinical findings and long-term outcomes were investigated. During the same period, the incidence of PSC among IBD patients was evaluated among 600 Crohn disease (CD) and 210 ulcerative colitis (UC) patients. Results: All 13 study patients diagnosed with PSC also presented with IBD. Eleven boys and two girls with a median age of 15.0 years old (9.0-17.8 years) were included. The cumulative incidence of PSC for UC was 5.7% (12 of 210) and 0.2% for CD (1 of 600), respectively. PSC occurred during follow-up for IBD for five patients (38.5%) whereas, IBD developed during follow-up for PSC for two patients (15.4%), and was diagnosed during the initial work-up for PSC for 6 patients (46.2%). For the 77.3 month median follow-up period, 9/13 patients (69.2%), neither the clinical symptoms nor blood test results worsened. Two cases (15.4%) developed liver cirrhosis and underwent liver transplantation. Among 13 PSC patients with IBD, two (15.4%) developed colorectal cancer, and no one developed cholangiocarcinoma. Conclusion: All patients with PSC in this study had associated IBD. The incidence of PSC was not rare compared to reports in adults. PSC should be considered during the management of IBD and vice versa in children.

Purpose: There is increasing prevalence of psychiatric disorders among inflammatory bowel Disease (IBD) population. Further, presence of psychiatric disorders has been shown as an independent predictor of quality of life among patients with IBD. We intended to explore the prevalence of various psychiatric disorders among pediatric and young adult population with IBD as a population-based analysis. Methods: We did a retrospective case control analysis using a deidentified cloud-based database including health care data across 26 health care networks comprising of more than 360 hospitals across USA. Data collected across different hospitals were classified and stored according to Systematized Nomenclature of Medicine-Clinical Terms. We preidentified 10 psychiatric disorders and the queried the database for the presence of at least one of the ten psychiatric disorders among IBD patients between 5 and 24 years of age and compared with controls. Results: Total of 11,316,450 patients in the age group between 5 and 24 years and the number of patients with a diagnosis of IBD, Crohn's disease or ulcerative colitis were 58,020. The prevalence of psychiatric disorders was 21.6% among IBD mainly comprising of depression and anxiety disorder. Multiple logistic regression analysis showed, IBD is 5 times more likely associated with psychiatric disorders than controls, p<0.001). We showed a steady increasing trend in the incidence of psychiatric disorders among IBD patients (2% in 2006 to 15% in 2017). Conclusion: Largest population-based analysis demonstrated an increased prevalence of psychiatric disorders among IBD patients. Our study emphasizes the need for psychological and mental health services to be incorporated as a part of the routine IBD clinic.

Backgrounds: Inflammatory bowel disease (IBD) including ulcerative colitis (UC) and Crohn's disease (CD) increased prevalence and economic burden. Objectives: This study aimed to investigate drug use pattern in IBD patients in a real world. Methods: National Health Insurance claim data from 2010 to 2014 were used in this population-based study. All IBD patients diagnosed during study period were enrolled. IBD medications included 5-aminosalicylic acid (ASA), glucocorticoid, immunomodulator and anti-tumor necrosis factor-${\alpha}$ agent(anti TNF-${\alpha}$). Growth rate of IBD prevalence, prescribed drug classes, duration of drug therapy and medication cost were analyzed. Number and percentage of patients for categorical variables, and mean and median for continuous variables were presented. Results: Total numbers of patients were 131,158 and 57,286 during 5 years, and their annual growth rate were 3.2 and 5.7% for UC and CD. UC and CD were prevalent in the 40-50 (41.2%) and 20-30 age groups (36.0%). About 60% of IBD patients was prescribed any of medications. 5-ASA was the most frequently prescribed, followed by corticosteroid and immunomodulator. Anti TNF-${\alpha}$ use was the lowest, but 5 times higher than UC in CD. Combination therapies with different class of drugs were in 29% for UC and 62% for CD. Mean prescription days per patient per year were 306 and 378, and the median medication cost per patient per year was KRW 420,000 (USD 383) and KRW 830,000 (USD755), for UC and CD, respectively. Conclusions: Increasing prevalence of IBD requires further studies to contribute to achieve better clinical outcomes of drug therapy.
