Reflux esophagitis is a common disease in developed nations. We describe the case of a female patient with endoscopic reflux esophagitis complicated by gastric dysmotility. Both electrogastrography and enterotachography were performed to detect gastric myoelectrical activity and pyloric sphincter function and evaluate gastric motility. The patient was treated only with herbal medications and general acupuncture, with electrical stimulation of the ST.36 (Zusanli) point, in addition to moxibustion therapy. After each primary and secondary treatment, the therapeutic effect was immediately evaluated. At the final follow-up 5 mon after the end of the secondary treatment, the patient’s general condition was assessed, in addition to the mucosa of the esophagus. At follow up, all the patients’ symptoms had disappeared, and the mucosa of the esophagus had returned to normal. We attributed these therapeutic effects to improved gastric dysmotility. To confirm the usefulness of this treatment method, studies of larger numbers of patients with reflux esophagitis treated with Korean traditional medicine are needed.

현대인들은 과거에 비해 풍부한 먹거리와 다양한 삶의 형태를 가지게 되었으나 바쁜 생활 속에 아침을 거르게 되고, 제 시간에 식사를 하지 못하는 등의 올바르지 못한 식습관을 형성하게 되었다. 이러한 식습관은 장기간 유지되면서 소화기관 장애로 이어지게 된다. 그에 가장 쉽게 발생하는 증상이 역류성 식도염과 삼킴 장애라고 불리는 연하 곤란이 있으며, 그 중 연하 곤란은 다양한 합병증의 형태로 발전하거나 위암, 후두암등의 전조증상으로 확인되기도 하여 빠르고 정확한 진단이 요구된다. 이에 따른 진단 결과는 현재도 의사가 수동적으로 판단하며 그 결과가 제각각이다. 여기서 말하는 진단 결과는 중증 정도를 말하는 것이며, 그에 따른 치료법이나 합병증을 파악할 때의 잘못된 진단으로 과한 치료나 부족한 대처로 이어지게 될 수도 있다. 본 논문에서는 연하 곤란의 심각 정도를 파악하기 위해 연하 곤란 진단 과정에서 식도로 이어지는 구간에 후두개곡과 이상와 부에 남는 잔여 음식물을 확인하기 위한 X-ray 이미지 처리에 K-means 알고리즘을 사용하는 프로그램을 개발하는 것을 연구하였다.

Gastroesophageal reflux disease (GERD) is a gastrointestinal disorder in which stomach contents reflux into the esophagus, causing complications such as mucosal damage. The purpose of this study was to determine the effect of Rhei Rhizoma and Scutellariae Radix mixture (RS) in chronic acid reflux esophagitis (CARE), one of the GERD. After inducing reflux esophagitis through surgery, the group was separated and the drug was administered for 2 weeks; Normal rats (Normal, n=8), chronic acid reflux esophagitis rats (Control, n=8), tocopherol 30 mg/kg-treated chronic acid reflux esophagitis rats (Toco, n=8), Rhei Rhizoma and Scutellariae Radix mixture 100 mg/kg-treated chronic acid reflux esophagitis rats (RSL, n=8), Rhei Rhizoma and Scutellariae Radix mixture 200 mg/kg-treated chronic acid reflux esophagitis rats (RSH, n=8). Gross lesion of esophageal mucosa after RS treatment showed a superior enhancement compared with that of Control group. Additionally, RS significantly decreased the levels of MPO and MDA, effectively inhibited NADPH oxidase, and regulated the expression of the AMPK/LKB1/NF-κB pathway. Moreover, it significantly increased the expression of tight junction proteins. Taken together, RS not only alleviates inflammation of the esophageal mucosa via the AMPK/LKB1/NF-κB pathway by reducing oxidative stress, but also improves esophageal function by modulating tight junction proteins.

Gastroesophageal reflux disease (GERD) is a disease that stomach contents continually refluxing, and is currently on the rise worldwide. The purpose of this study is to find natural materials that can reduce side effects and effectively treat chronic acid reflux esophagitis (CARE), one of GERD. First, the antioxidant activity was confirmed by varying the mixing ratio of Coptidis Rhizoma and Evodiae Fructus, which are effective against chronic reflux esophagitis. After, animal experiments were conducted using a 1:1 (CE) and 1:2 (CEE) combination ratio of Coptidis Rhizoma and Evodiae Fructus, which had the best antioxidant efficacy. Gross lesion of esophageal mucosa after CE or CEE treatment showed a superior enhancement compared with that of CARE control rats. Additionally, its inhibited MAPK phosphorylation and led NF-κB inactivation through the suppression of IκBα phosporylation by regulating Nrf2/Keap-1, and NF-κB inactivation induced reduced protein expressions including inflammatory mediators and cytokines. Moreover, its improved esophageal barrier function through upregulating protein expressions of tight junction protein, whereas downregulating protein expressions of MMPs. Taken together, a mixture of Coptidis Rhizoma and Evodiae Fructus can attenuate the esophageal mucosal ulcer by inhibiting MAPK and NF-κB pathway, and upregulating proteins associated with tight junction.

Objectives : This study was to evaluate inhibitory effects of Naegwan-acupuncture($PC_6$) on acute RE(reflux esophigitis) rat induced by pylorus and forestomach ligation operation. Methods : Twenty seven SD rats were divided three groups (intact normal rat; RE control rat; RE control rat respectively stimulated by Naegwan point($PC_6$)). All rats was fasted for 18 h but free water, we induced RE by pylorus and forestomach ligation operation. Six hour after the operation, rats were sacrified, collected bloods in the abdominal vein, dissected a esophagus and stomach. The stomach was washed a 1 ml PBS to research gastric volume, pH, acidity and mucin release of gastric juice, esophagus was cut longitudinally and pictured a innter mucosa area to research damages in esophagus. The proinflammatory cytokine and chemokine including IFN-${\gamma}$, TNF-${\alpha}$, IL-$1{\beta}$, IL-6 and MCP-1 were analyzed by ELISA kit. Results : 1. Significantly, death rate of $PC_6$ acupuncture rat group was decreased compared to that of RE control group. 2. Gastric Volume, gastric injury and esophageal mucosa demage were decreased significantly, too. 3. Compared with RE, all of the proinflammatory cytokine and chemokine analyzed in serum of $PC_6$ were decreased remarkably. Especially, there were significant meanings TNF-${\alpha}$, IL-6 and MCP-1 in serum of $PC_6$ were decreased. Conclusion : The results suggest that antiinflammatory and protecting effects of PC6 could attenuate the severity of reflux esophagitis and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.

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.

Objectives : This study investigated oriental diagnosis and treatment of reflex esophagitis (RE) such as syndrome differentiation and herbal medicine by reviewing Chinese journals. Methods : A journal search was performed using China National Knowledge Infrastructure (CNKI) from January 2006 to December 2010. The keywords were the various combinations of 'reflex esophagitis', 'Chinese medicine', 'syndrome differentiation', and 'herbal medicine'. All types of journal entries that explained or referred to herbal medicines and definite syndrome differentiations were included. The Types of the journals were randomized clinical trials (RCT), reviews, essays, case series and reports. Vague syndrome differentiations and experimental studies were excluded. Selected journals were extracted and summarized by two researchers independently. Results : 47 Chinese entries were finally selected. 61% of them were case-control trials that had non-randomized, active controlled clinical trials. 36 kinds of syndrome differentiations about RE were investigated. We summarized and divided them into 10 syndrome differentiation groups. 肝胃不和(syndrome of liver qi invading the stomach) in syndrome differentiation, 和胃降逆 (harmonize the stomach and direct qi downward) in method of treatment, and Jwa kum-whan (左金丸) were cited with high frequency in RE. Conclusions : We find that many kinds of syndrome differentiation groups and herbal medicines for reflex esophagitis are used in China, compared with Korea. Further studies will be required about oriental syndrome differentiation and treatment of this disease.

Objectives : The present study was conducted to evaluate protective effects of Combined Extract of young persimmon fruit and citrus peel (PCM) in Reflux Esophagitis(RE) rats.Methods : Twenty-four Sprague-Dawley (SD) rats were divided four groups and each group had six rats ; Normal group, RE control group, RE group treated PCM 50 ,100 mg/kg body weight group. Reflux esophagitis was induced that tied the pylorus and fundus in SD rats stomach. PCM was administered at 50, 100 mg/kg body weight 2 hrs prior to induction of RE. After 6 hrs, the effects of PCM treated rats were compared with those of normal and control rats. We have performed an analysis such as pH of stomach secretion, oxidative stress biomarkers in serum, and western blot.Results : The increased esophageal mucosa damage by RE was markedly improved by PCM treatment in a dose-dependent manner. Also, the administration of PCM decreased the elevated serum reactive oxygen species (ROS) and peroxynitrite (ONOO^-) in serum. The protein expressions of anti oxidant such as SOD, catalase, GPx exhibited down-regulation by PCM treatment in tissues. And, PCM effectively reduce inflammatory cytokines such as inflammation-related proteins cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), Tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) in RE rats. In addition, NFκB and p-IκBɑ were decreased in PCM-adiministrated RE rats. But there was no difference on stomach secretion pH between reflux esophagitis rats and PCM administration rat group.Conclusions : In conclusion, administration of PCM (50, 100 mg/kg body weight) made esophagus have less inflammation and injury by decreased NFκB path way. These findings suggest that PCM could have Improving effects on reflux esophagitis.
