본 연구는 다량 미네랄 6종 및 미량 미네랄 8종이 함유된 천연 미네랄 워터의 기능성을 확인하기 위해 역류성 식도염 유발 동물모델을 이용하여 개선 효과를 분석하였다. RAW264.7에서의 세포 생존율 측정 결과를 통해 미네랄 워터는 세포에 대한 독성이 없음을 확인하였으며, 역류성 식도염 동물모델에서 위 내용물 역류에 의한 식도 손상을 감소시켰으며, 식도 점막 보호 작용으로 인해 세포 연접 단백질 발현을 억제하였다. 따라서, 미네랄 워터의 식도 보호 작용은 조직 내 염증성 단백질 및 점막 재생 관련 단백질을 조절함으로써 나타난 것으로 사료된다. 이러한 연구 결과를 통해, 미네랄 워터의 기능성을 확인함으로써 음용수, 식품 생산 등의 다양한 산업 분야에서의 활용성과 가축 생산에 있어 면역증진 및 염증 관련 질병에 대처할 수 있는 친환경 기능성 사료첨가제로서의 미네랄 워터의 이용 가치를 확인할 수 있었다.

Purpose: To evaluate the prevalence of esophageal reflux-induced symptoms after gastrectomy owing to gastric cancer and assess the relationship between esophageal reflux-induced symptoms and quality of life. Materials and Methods: From January 2012 to May 2012, 332 patients were enrolled in this cross-sectional study. The patients had a history of curative resection for gastric cancer at least 6 months previously without recurrence, other malignancy, or ongoing chemotherapy. Esophageal reflux-induced symptoms were evaluated with the GerdQ questionnaire. The quality of life was evaluated with the European Organization for Research and Treatment QLQ-C30 and STO22 questionnaires. Results: Of the 332 patients, 275 had undergone subtotal gastrectomy and 57 had undergone total gastrectomy. The number of GerdQ(+) patients was 58 (21.1%) after subtotal gastrectomy, and 7 (12.3%) after total gastrectomy (P=0.127). GerdQ(+) patients showed significantly worse scores compared to those for GerdQ(-) patients in nearly all functional and symptom QLQ-C30 scales, with the difference in the mean score of global health status/quality of life and diarrhea symptoms being higher than in the minimal important difference. Additionally, in the QLQ STO22, GerdQ(+) patients had significantly worse scores in every symptom scale. The GerdQ score was negatively correlated with the global quality of life score (r=-0.170, P=0.002). Conclusions: Esophageal reflux-induced symptoms may develop at a similar rate or more frequently after subtotal gastrectomy compared to that after total gastrectomy, and decrease quality of life in gastric cancer patients. To improve quality of life after gastrectomy, new strategies are required to prevent or reduce esophageal reflux.

This study was designed to determine the protective effect of Rumex Aquaticus Herba extracts containing quercetin-3-${\beta}$ -D-glucuronopyranoside (ECQ) on experimental reflux esophagitis. Reflux esophagitis was induced by surgical procedure. The rats were divided into seven groups, namely normal group, control group, ECQ (1, 3, 10, 30 mg/kg) group and omeprazole (30 mg/kg) group. ECQ and omeprazole groups received intraduodenal administration. The Rats were starved for 24 hours before the experiments, but were freely allowed to drink water. ECQ group attenuated the gross esophagitis significantly compared to that treated with omeprazole in a dose-dependent manner. ECQ decreased the volume of gastric juice and increased the gastric pH, which are similar to those of omeprazole group. In addition, ECQ inhibited the acid output effectively in reflux esophagitis. Significantly increased amounts of malondialdehyde (MDA), myeloperoxidase (MPO) activity and the mucosal depletion of reduced glutathione (GSH) were observed in the reflux esophagitis. ECQ administration attenuated the decrement of the GSH levels and affected the MDA levels and MPO activity. These results suggest that the ECQ has a protective effect which may be attributed to its multiple effects including anti-secretory, anti-oxidative and anti-inflammatory actions on reflux esophagitis in rats.

Objectives: The purpose of this study was to report the effectiveness of Korean medicine in the treatment of reflux esophagitis. Methods: A 62-year-old male patient had reflux esophagitis that occurred one year after a proximal gastrectomy for gastric ulcer in 2020. The patient underwent drug treatment in 2021 and inpatient treatment in 2022 at Mokpo Hankook Hospital, but he did not improve. We treated him with Korean medical treatments, including herbal medicines (Pyungjingunbi-tang-gami), acupuncture, and moxibustion. His symptom severity was assessed with a daily visual analog scale (VAS) for heartburn, upper abdomen pain, and acid reflux. Results: After treatment, the patient's symptoms were improved. The severity of heartburn and acid reflux was reduced from VAS 7 to VAS 1, and his upper abdomen pain was improved from VAS 6 to VAS 1. The symptom frequency was also reduced. Conclusion: Korean medicine treatment could be an effective and quick treatment for reflux esophagitis.

The pathophysiology of Gastroesophageal reflux disease (GERD) has been known that it is developed when the offense-primarily the gastric acid-pepsin content of the refluxate-overcomes a 3-tiered esophageal protective defense. consisting of antireflux mechanisms, luminal clearance mechanisms, and tissue resistance. Laryngopharyngeal reflux (LPR), which is known as an extraesophageal variant of GERD, has been considered to be developed by transient lower esophageal sphincter relaxation (TLESR), direct mucosal injury by gastric contents, more sensitive mucosa compared to esophagus, and absence of buffering effect and aggravation of the injury due to pepsin. However, hypothesis of the pathophysiology in both entities are numerous and still lack of understanding for being a theory. There is no conflict that understanding the pathophysiology is necessary for resolving the problems of these diseases and numerous studies and results have been releasing. This review could provide clinicians dealing with GERD and LPR with applicable new information and help for overcoming the clinical obstruction.

This study was conducted to examine the current status of traditional korean medicine studies on gastroesophageal reflux disease in Korea, identify deficiencies, and suggest the direction of future medicine research methods to lay the foundation for traditional korean medicine treatment. All domestic papers on the korean traditional treatment of gastroesophageal reflux disease were selected among the literature published until August 2022 in six domestic databases. A total of 52 selected research data were classified into experimental research papers, clinical research papers, and review papers. In experimental papers, to evaluate the effectiveness of treatment, improvement of esophageal mucosal lesions, anti-inflammatory mechanisms, antioxidant mechanisms, esophageal mucosal protection mechanisms, gastric peristalsis control, and gastric acid secretion inhibition mechanisms were used as evaluation measures. In the clinical research paper, the basis for diagnosis of cases was clinical symptoms through medical history listening and diagnosis through visits to hospitals in the past. The average treatment period was 40.7 days, and the duration of treatment was not significantly affected by the duration of the disease. The most widely used Korean medicine treatment intervention was herbal medicine. There were 3 literature review studies, 3 systematic literature review and meta-analysis studies, 1 comparative review study for clinical trial guideline development, all using Chinese papers. This study included all domestic papers on gastroesophageal reflux disease to identify the research trend of the Korean oriental medicine community, and based on this, it is meaningful to confirm areas that need to be supplemented in future research plans.

The aim of this study was to investigate the effects of Ulmi Pumilae cortex extracts on acute reflux esophagitis rats induced by pylorus and forestomach ligation operation. 40 rats were divided into five groups; Normal group, Sham group, Control group, T1 group and T2 group. 4 groups has a laparotomy after controled 2weeks and sham group, T1 group, T2 group has ligation in stomach. After laparotomy, all group`s body weight, gastric volume, gastric juice PH, SOD activities, catalase activities, lipid peroxidation, total glutathione, the effects on esophageal and stomach mucosa damage were checked. There was significant statistical differences between control group and Ulmi Pumilae cortex extracts adminitration groups(T1 and T2 group) in terms of gastric volume decreasing. Also, adminitration groups has significant effect than control group in decreasing mucosa damage. SOD(superoxide dismutase) and catalase activities has a significant statistical differences between control group and T2 group not in T1 group. These results suggest that the medication of Ulmi Pumilae cortex extracts is effective for the treatment of acute reflux esophagitis in terms of decerasing gastric volume and mucosa damage. Especially, the results were shown to be more positive in High-dose administration group (T2 group) than in Low-dose administration group (T1 group) in SOD and catalase activities.

A laparoscopic wedge resection for a submucosal tumor, which is close to the gastroesophageal junction, is technically challenging. This can be a dilemma to both patients and surgeons when the tumor margin involves the gastroesophageal junction because a wedge resection in this situation might result in a deformity of the gastroesophageal junction or an injury to the lower esophageal sphincter, which ultimately results in lifelong gastroesophageal reflux disease. The patient was a 42 year-old male, whose preoperative endoscopic ultrasonographic finding did not rule out a gastrointestinal stromal tumor. He underwent a laparoscopic gastric wedge resection and prophylactic anterior partial fundoplication (Dor) and was discharged from hospital on the fifth postoperative day without any complications. There were no symptoms of reflux 5 months after surgery. A laparoscopic wedge resection and prophylactic anti-reflux surgery might be a good surgical option for a submucosal tumor at the gastroesophageal junction.
