Effects of cheonggukjang on immunohistochemical reactions in gastrointestinal (GI) tract of rats were investigated. $CD4^+/CD8^+$ immunoreactive cells of cheonggukjang-fed diet groups were more strongly stained in lamina propria of mucosa and submucosa than those of basal diet group. Universal nitric oxide synthase immunoreactive density in colon was mildly stained in surface epithelium and mucous secretory gland, and strongly stained in submucosa and myenteric plexus in muscle layers of all cheonggukjang-fed diet groups. Protein kinase C-${\alpha}$ immunoreactive cells in colons of 15 and 25% cheonggukjang-fed diet groups were more strongly stained in mucosa, submucosa, and muscle layers than those of basal diet group. These results indicate mucosal immune activity, gastrointestinal motility, blood circulation, and physiological activities of enteroendocrine cells in GI tract could be increased with cheonggukjang intake.

The gastrointestinal tract(GI) is the most frequently involved site of mucosa associated lymphoid tissue(MALT) lymphoma. Stomach is the most common site of involvement among the GI tract. In some case of MALT lymphoma, it is detected in colon. Almost all diagnosis is established by pathological examination of the surgical or endoscopic specimens. We reported a case of rectal MALT lymphoma by colonoscopic polypectomy.

위장관 출혈은 단일 질환이 아니라 광범위한 위장 질환의 증상 및 임상적 발현이다. 임상적 양상에 따라 명백한 출혈, 잠재 출혈, 원인 불명 출혈로 나눌 수 있으며, 출혈 위치에 따라 Treiz 인대를 기준으로 상부 또는 하부 위장관 출혈로 분류할 수 있다. 혈관 질환, 용종, 종양, 크론병, 이소성 췌장 및 이소성 위조직 등 다양한 질환이 위장관 출혈을 일으킬 수 있다. 명백한 출혈을 위한 영상 검사기법은 CT 혈관조영술, 고식적 혈관조영술 및 핵의학적 검사 등이 사용된다. 잠재 위장관 출혈을 평가하기 위한 영상검사로는 CT 소장조영술이 주로 사용되며, 위장관을 적절히 팽창해서 영상을 획득해야 위음성 혹은 위양성을 최소화하여 진단능을 높일 수 있다. CT 소장조영술에서 진단이 확실하지 않은 경우, Meckel scan이 보완적으로 사용될 수 있다. 원인 불명 위장관 출혈에 대한 검사는 임상 양상과 임상의 혹은 영상의학과 의사의 선호도에 따라 다양한 검사가 시행될 수 있으며, 이에 대한 추가적인 연구가 필요하다.

Objective: Pyungwi-san (PWS) plays a role in a number of physiologic and pharmacologic functions in many organs. Interstitial cells of Cajal (ICCs) are pacemaker cells that generate slow waves in the gastrointestinal (GI) tract. We aimed to investigate the beneficial effects of PWS in mouse small-intestinal ICCs. Methods: Enzymatic digestion was used to dissociate ICCs from the small intestine of a mouse. The whole-cell patch-clamp configuration was used to record membrane potentials from the cultured ICCs. Results: ICCs generated pacemaker potentials in the GI tract. PWS produced membrane depolarization in the current clamp mode. Pretreatment with a $Ca^{2+}$-free solution and a thapsigargin, a $Ca^{2+}$-ATPase, inhibitor in the endoplasmic reticulum, eliminated the generation of pacemaker potentials. However, only when the thapsigargin was applied in a bath solution, the membrane depolarization was not produced by PWS. Furthermore, the membrane depolarizations due to PWS were inhibited not by U-73122, an active phospholipase C inhibitor, but by chelerythrine and calphostin C, protein kinase C inhibitors. Conclusions: These results suggest that PWS might affect GI motility by modulating the pacemaker activity in the ICCs.

Objectives : The aim of this study was to understand application of Ganhap(干合) theory to human body. Methods : We investigated 5 important sphincters along the alimentary tract (Larynx, Pharynx, Cardia, Pyrolus, Iliocecal portion) comparing with the function of Viscera and Bowels, also with Meridian and collateral theory. Results & Conclusions : We can analyze 5 important sphincters along the alimentary tract into relationship of Ganhap. 1. Larynx are related with the combination of Byeong-Sin(丙辛合). 2. Pharynx are related with the combination of Jeong-Im(丁壬合). 3. The Cardia is related with the combination of Mu-Gyu(戊癸合). 4. The Pyrolus is related with the combination of Gap-Gi(甲己合). 5. Ileocecal portion is related with the combination of Eul-Gyeong(乙庚合).

Biliary tract cancer (BTC) is a rare cancer and is associated with a poor prognosis. To understand the genetic characteristics of BTC, we analyzed whole-exome sequencing data and identified somatic mutations in patients with BTC. Tumors and matched blood or normal samples were obtained from seven patients with cholangiocarcinoma who underwent surgical resection. We discovered inactivating mutations of tumor suppressor genes, including APC, TP53, and ARID1A, in three patients. Activating mutations of KRAS and NRAS were also identified. Our analyses identified somatic mutations in Korean patients with BTC.

To research the trends of study and the guidelines of investigation and management about gastrointestinal (GI) disease in oriental medicine, we reviewed and analysed articles published in Korea from 2004 to 2009. The western medicine in medical treatments of GI tract is notorious for their side effects. But, in oriental medicine, we couldn't find any side effects. Although we treat or manage clinical practices of the GI disease every day, however, we do not have abundant evidences about scientific mechanisms of those treated with oriental medicine therapy. Therefore, we suggest that the upward of qualities of life and the improvement of health-care system through the development of oriental medicine therapies in Korea will be need.

Objective: To determine the impact of dedicated subspecialized radiologists in multidisciplinary team (MDT) discussions on the management of lower gastrointestinal (GI) tract malignancies. Materials and Methods: We retrospectively analyzed the data of 244 patients (mean age ± standard deviation, 61.7 ± 11.9 years) referred to MDT discussions 249 times (i.e., 249 cases, as five patients were discussed twice for different issues) for lower GI tract malignancy including colorectal cancer, small bowel cancer, GI stromal tumor, and GI neuroendocrine tumor between April 2018 and June 2021 in a prospective database. Before the MDT discussions, dedicated GI radiologists reviewed all imaging studies again besides routine clinical reading. The referring clinician's initial diagnosis, initial treatment plan, change in radiologic interpretation compared with the initial radiology report, and the MDT's consensus recommendations for treatment were collected and compared. Factors associated with changes in treatment plans and the implementation of MDT decisions were analyzed. Results: Of the 249 cases, radiologic interpretation was changed in 73 cases (29.3%) after a review by dedicated GI radiologists, with 78.1% (57/73) resulting in changes in the treatment plan. The treatment plan was changed in 92 cases (36.9%), and the rate of change in the treatment plan was significantly higher in cases with changes in radiologic interpretation than in those without (78.1% [57/73] vs. 19.9% [35/176], p < 0.001). Follow-up records of patients showed that 91.2% (227/249) of MDT recommendations for treatment were implemented. Multiple logistic regression analysis revealed that the nonsurgical approach (vs. surgical approach) decided through MDT discussion was a significant factor for patients being managed differently than the MDT recommendations (odds ratio, 4.48; p = 0.017). Conclusion: MDT discussion involving additional review of radiology examinations by dedicated GI radiologists resulted in a change in the treatment plan in 36.9% of cases. Changes in treatment plans were significantly associated with changes in radiologic interpretation.

Gastrointestinal (GI) hemangiomas are relatively rare benign vascular tumors. The choice of an appropriate diagnostic method depends on patient age, anatomic location, and presenting symptoms. However, GI hemangiomas are not a common suspected cause of GI bleeding in children because of their rarity. Based on medical history, laboratory results, and imaging study findings, the patient could be treated with either medication or surgery. Herein, we report 3 cases of GI hemangioma found in the small bowel, rectum, and GI tract (multiple hemangiomas). Better knowledge and understanding of GI hemangioma could help reduce the delayed diagnosis rate and prevent inappropriate management. Although rare, GI hemangiomas should be considered in the differential diagnosis of GI bleeding.
