액상소화제의 법랑질 부식능을 알아보기 위하여 마트에서 쉽게 구입할 수 있는 2종의 액상소화제와 약국에서 판매하는 1종의 액상소화제 그리고 대조군으로 생수를 선정하였다. 음료의 pH와 적정산도를 측정하고, 시편을 제작하여 음료에 1, 3, 5, 10, 15, 30분을 침지한 후 나타나는 양상을 표면 미세 경도계로 측정하여 다음과 같은 결론을 얻었다. 대조군인 생수를 제외한 모든 액상소화제의 pH가 4.0 이하로 나타났으며 위청수에서 $2.93{\pm}0.00$으로 가장 낮았다. pH 5.5로 변환하는 데 필요한 적정산도 또한 위청수에서 1.27 ml로 가장 높게 나타났다. 모든 액상소화제에서 침지시간이 증가함에 따라 표면경도가 감소하였으며 음료 30분 처리 후 표면 경도값은 위청수에서 $207.80{\pm}15.52$ VHN으로 가장 낮았고, 까스활명수 $216.86{\pm}4.01$, 생록천 $223.28{\pm}9.56$ 순이었다. 실험에 사용된 모든 액상소화제는 치아 법랑질에 부식을 유발하였으며, 음료처리 후에 pH가 가장 낮고 적정산도가 가장 높은 위청수에서 가장 낮은 표면 경도 값을 보여 실험에 사용된 액상소화제 중 가장 많은 법랑질 부식을 유발하였다. 따라서 액상소화제의 섭취는 법랑질표면경도를 감소시켜 치아 부식을 유발할 수 있으므로 이에 대한 대처방안이 마련되어야 할 것이다.

Morphology, histology, and histochemical characteristics of the digestive tract of the guirine goby (Rhinogobius giurinus: Gobiidae), collected from the coast of Jeju Island, Korea, were investigated. The digestive tract of R. giurinus, which is a brackish water species, has a short (relative length of gut=0.42), simple, and narrow gut. The gastric glands are well developed in the stomach, but pyloric caeca are absent. The mucosal folds are regularly branched, and the muscularis extern a is thickest in the esophagus, which also contained the most mucus-secreting goblet cells (P<0.05). In R. giurinus, digestive function occurs in the anterior portion of the digestive tract, where mucus protects the tract from the actions of digestive enzymes and functions to activate digestion.

Portobiliary fistulas are rare but may lead to life-threatening complications. Biliary plastic stent-induced portobiliary fistulas during endoscopic retrograde cholangiopancreatography have been described. Herein, we present a case of portal cavernography and recurrent hemobilia after endoscopic retrograde cholangiopancreatography in which a portobiliary fistula was detected in a patient with portal biliopathy. This likely indicates a change in clinical presentation (from bilhemia to hemobilia) after biliary drainage that was successfully treated by placement of a fully covered, self-expandable metallic stent.

Purpose: The purpose of this study is to recognize menstrual pattern, stress, digestive disorder of female college students who have oligomenorrhea and effects of Gamiguibi-tang. Methods: We researched 30 female students who responded to have menstrual irregulation at ${\bigcirc}{\bigcirc}$ college by questionnaires investigating their menstruation, stress, digestive disorder, and changes of symptoms before and after taking Gamiguibi-tang. Results: 1. There was statistical correlation between menstrual pattern and Qi-Stasis Questionnaire symptoms. 2. There was statistical correlation between menstrual pattern and digestive disorder symptoms. 3. There was statistical correlation between improvement of Qi-Stasis Questionnaire symptoms and usage of Gamiguibi-tang. 4. There was statistical correlation between improvement of digestive disorder symptoms and usage of Gamiguibi-tang. Conclusions: This study showed the stress and digestive disorder symptoms are effectively relieved by Gamiguibi-tang. By this result we expect that Gamiguibi-tang can be used for oligomenorrhea caused by stress or digestive disorder.

Distress in patients with digestive cancers can considerably impact not only their treatment adherence but also their health-related quality of life. Early distress recognition in patients, appropriate interventions by the oncology team, or referral to mental health professionals, can enhance the treatment efficiency. This review aims to provide an overview of distress evaluation and its management in patients with cancer, specifically digestive cancers, and to address the psychological responses and distress that occur in those patients during treatment. Furthermore, the review will introduce possible psychological interventions for patients with digestive cancers who experience significant distress, depending on the duration and planning of the treatment.

본 연구는 3종의 이매패류를 대상으로 소화맹낭의 소화효소 구성 및 활성도에 대해 조사하였다. 본 연구에 사용된 이매패류는 지중해담치, 개조개 및 꼬막이며, 이들은 한국 남해안에서 2010년 11월에 채집하였다. 지중해담치, 개조개, 꼬막의 소화맹낭을 구성하는 소화효소는 amylase와 cellulase가 약 95%로 대부분을 차지하였다. 소화맹낭에서 amylase와 cellulase 활성도는 지중해담치는 2.6과 0.8 U/mg, 개조개는 2.4와 8.8 U/mg, 꼬막은 7.3과 11.8 U/mg였다. 그리고 소화맹낭의 소화효소 가운데 protease의 활성도는 지중해담치, 개조개, 꼬막에서 각각 0.00019, 0.00028, 0.00022 U/mg로 가장 낮았다.

Tongue acupuncture is not only a body acupuncture treatment for the tongue but also a new microacupuncture treatment. Tongue acupuncture is a very promising treatment from a diagnostic and therapeutic point of view. According to several studies, Guan's tongue acupuncture and tri-tongue acupuncture are frequently used. Tongue acupuncture can be used for dysphagia, dysarthria, aphasia, insomnia, autism spectrum disorder, burning mouth syndrome, and cerebral palsy.

Background/Aims: Transoral incisionless fundoplication (TIF) is an accepted anatomic treatment for gastroesophageal reflux disease in selected patients. In this report, we analyze our institution's programmatic allocation of resources during the safe implementation of TIF as a new procedure. Methods: A retrospective analysis of all patients who underwent TIF from January 2020 to February 2021 at our institution was performed. The process of initially allocating the operating room (OR) with overnight admission and postoperative esophagram for added safety, and subsequently transitioning TIF to the endoscopy suite (ES) as an outpatient procedure was described. Patient safety and outcomes were evaluated during transition. Results: Thirty patients who underwent TIF were identified. The mean age was 51.2±16.0 years. TIF was performed in an OR in nine patients (30%) and 21 (70%) in the ES. All the OR patients were admitted overnight and had routine esophagogram. In contrast, four (19%) from the ES group required clinically-indicated admission and three (14.2%) required esophagram. The mean procedure duration was significantly lower in the ES group (65.7 min vs. 84 min, p=0.02). Conclusions: A stepwise, resource-efficient process was described that allowed safe initiation of TIF as a new technique and its effective transition to a fully outpatient procedure.

Objective: To investigate the association between the gene polymorphisms of angiotensin-converting enzyme (ACE) and digestive system cancer risk. Method: A search was performed in Pubmed, Medline, ISI Web of Science and Chinese Biomedical (CBM) databases, covering all studies until Sep 1st, 2013. Statistical analysis was performed by using Revman5.2 and STATA 12.0. Results: A total of 15 case-control studies comprising 2,390 digestive system cancer patients and 9,706 controls were identified. No significant association was found between the I/D polymorphism and digestive cancer risk (OR=0.93, 95%CI = (0.75, 1.16), P=0.53 for DD+DI vs. II). In the subgroup analysis by ethnicity and cancer type, no significant associations were found for the comparison of DD+DI vs. II. Results from other comparative genetic models also indicated a lack of associations between this polymorphism and digestive system cancer risks. Conclusions: This meta-analysis suggested that the ACE D/I polymorphism might not contribute to the risk of digestive system cancer.
