Objectives: Yijin-tang-gamibang has been used in the Korean Medicine for treating various digestive disease. This study was aimed to investigate the effects and safety of Yijin-tang-gamibang in reflux esophagitis through the analysis of articles. Method: A total of 9 articles about Yijin-tang-gamibang and reflux esophagitis were used to develop this article. Results: According to basic research and clinic research data, it is supported that Yijin-tang-gamibang was useful prescription in reflux esophagitis. Yijin-tang-gamibang has favorable protective effects on the reflux esophagitis induced by pylorus and forestomach ligation in rats. After treatment with Yijin-tang-gamibang, patients showed improvement in all symptoms associated with reflux esophagitis and functional dyspepsia, including general condition. And Yijin-tang-gamibang did not show any toxic effect in single oral dose toxicity test. Conclusion: The results of this study suggest that Yijin-tang-gamibang showed favorable protective effects on the reflux esophagitis. However, it proved insufficient to confirm its efficacy owing to lack of clinical studies of high quality. So, we need well designed studies to verify clinical efficacy of Yijin-tang-gamibang hereafter.

Objectives: This aim of this study is to compare the reflux esophagitis improvement effects of Sepiae Os, Arcae Concha, Ostreae Concha, and Proton Pump Inhibitor(esomeprazole) through rat experiments. Methods: NO production inhibitory effect was measured by NO production amount and iNOS mRNA expression level in cell lines. iNOS, $TNF-{\alpha}$ and $p-I{\kappa}B$, and serotonin were compared using immunohistochemistry at the rat reflux esophagitis. Reflux esophagitis connection external form, lower esophageal sphincter, and gap were observed and an esophageal inflammatory indicator, IL-6 activity was also evaluated by immunohistochemistry. Results: NO production and iNOS mRNA expression was showed concentration dependent decrease in cell lines treated with Sepiae OS, Arcae Concha, and Ostreae Concha at the experiments of cell lines. In the suppression of iNOS and $p-I{\kappa}B$ at the rat reflux esophagitis, Sepiae Os treat group(SOT) and Ostreae Concha treat group(OCT) were more effective. In the increase of serotonin at the rat reflux esophagitis, ACT, MT and OCT were more effective. Damage of lower esophageal sphincter, and gap between esophageal keratin and mucosa were observed less at the SOT, ACT, OCT. In the suppression of IL-6 at the rat reflux esophagitis, SOT and OCT were more effective than GE and, SOT was more effective than MT significantly. Conclusions: The anti-inflammatory effect was the best in the SOT and lower esophageal sphincter muscle contraction was the best in the ACT at the rat reflux esophagitis. Sepiae OS was more effective than esomeprazole in the suppression of iNOS, $TNF-{\alpha}$, and IL-6.

Objectives : This study was carried out to investigate the inhibitory effect of Banhasasim-tang on early reflux esophagitis by control of gastric peristalsis and the lower esophageal sphincter in mice. Methods : Experimental mice were classified into three groups. The normal group were mice with no inflammation. The control group were mice with gastroesophageal reflux elicited by alcohol. The sample group were mice administered Banhasasim-tang after gastroesophageal reflux elicitation. We observed morphological change and production of ghrelin, substance P, and inducible nitric oxide synthase (iNOS) in gastroesophageal junction mucosa. In addition, we examined change of epithelial junction in esophageal mucosa and change of lower esophageal sphincter distribution. Results : The migration of inflammation-related cells in lamina propria of gastroesophageal junction decreased more in the sample group than in the control group. The positive reaction of ghrelin, substance P, and iNOS significantly decreased more in the sample group than in the control group (p<0.05). Injury of the epithelial junction in the esophageal mucosa and outer oblique layer in the lower esophageal sphincter were significantly mitigated by Banhasasim-tang administration in the sample group (p<0.05). Conclusions : According to the above results, it is supposed that Banhasasim-tang inhibits early reflux esophagitis by controlling not only gastric peristalsis and acid secretion through ghrelin, and substance P but also the lower esophageal sphincter through iNOS.

Objectives: This study investigated the administration of Jeungmiyijin-tang (JYT) to rats with reflux esophagitis (RE) induced by pylorus and forestomach ligation operations. Methods: Twenty laboratory rats were divided into three groups with 5~7 rats in each group. The control group consisted of rats with no inflammation (CON). The RE group had rats with gastroesophageal reflux elicited by pylorus and forestomach ligation operations. The JYT group had rats that were orally administered Jeungmiyijin-tang (1.5 ml/day/300 g) once a day for 14 days before reflux esophagitis was induced by the pylorus and forestomach ligation operations. Six hours after the operations, the rats were sacrificed, morphological changes were observed, and histological examinations were done in the stomach and esophagus lesion areas. If apoptosis was observed, the apoptotic cells in the esophagus lesion areas were counted. Results: The morphological and histochemical changes consisted of various injuries from hemorrhagic erosion in the RE group, while there were significantly fewer in the JYT group. The RE group marked increases of gastric mucosa erosion and infiltration of inflammatory cells in the submucosa, as well as cell division in the epithelial layer, the proliferation and degranulation of mast cells, and increases in the IL-$1{\beta}$, TNF-${\alpha}$, and MMP-9 expressions in the esophagus of the rats. The JYT group was inhibited above expression compared with the RE group. Apoptosis was statistically significantly decreased in the JYT group compared with the RE group. Conclusions: According to the above results, it appears that Jeungmiyijin-tang inhibits the expression of pro-inflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$, and MMP-9) and apoptosis in the esophagus mucosa, thereby preventing esophageal mucosal damage from esophageal reflux.

1. Objectives: This case study reports a Taeumin patient with Gastro-esophageal reflux disease who had suffered from chest pain, heartburn, acid regurgitation and dyspepsia who improved after Yeoldahanso-tang(Reduohanshao-tang) medication. 2. Methods: This patient had started treatment with Yeoldahanso-tang(Reduohanshao-tang), three times per day for three months and assessed the changes of the main symptoms such as chest pain, heartburn and acid regurgitation from baseline to post-treatment using a questionnaire with visual analogue scale(VAS). Electrogastrography(EGG) was also performed for assessment of gastric function from baseline to post-treatment. 3. Results: After the treatment, symptoms of GERD such as chest pain, heartburn, and acid regurgitation are almost disappeared. The patient don't need to take the proton pump inhibitor therapy. There was significant increase of % bradygastria parameters in fed EEG after treatment with Yeoldahansotang(Reduohanshao-tang). And significant increase of the power ratio after treatment was shown (20.5), compared with initial EGG(0.0). 4. Conclusions: This results show Yeoldahanso-tang(Reduohanshao-tang) can be used to treat GERD with Dry-heat symptom of Taeumin. This results suggest that Sasang Constitutional treatment for GERD patients who has a chronic condition with highly recurrence rate, might be a candidate for a therapeutic agent. Also effects of Yeoldahanso-tang(Reduohanshaotang) on GERD need further studies such as clinical trials.

Objectives : The object of this study was to observe the protective effects of 8 types of individual herbal components of Yijintang-gamibang, on the reflux esophagitis (RE) in rats as compared with omeprazole. Methods : Each 100 mg/kg individual herbal component was orally pretreated, at 1 hr before and 6 hrs after pylorus and forestomach ligation, the changes on the esophageal lesion areas, gastric volumes, acid and pepsin outputs, antioxidant effects, esophageal total hexose and sialic acid contents were observed with changes on the esophageal histopathology. The results were compared with an omeprazole 10 mg/kg treated group. Results : Pylorus and forestomach ligation-induced RE were inhibited by treatment of all 8 herbal components and omeprazole except for Pinella Rhizoma and Massa Meicata Fermentata, in order of Atractylodis Rhizoma, Citri Pericarpium, omeprazole, Glycyrrhizae Radix, Hordei Fructus Germiniatus, Holelen and Citri Pericarpium, as compared with RE control. Pinella Rhizoma and Massa Meicata Fermentata did not show any favorable protective effects against RE nor antioxidant effects in the present study. Conclusions : The main active herbal components showing favorable protective effects on RE of Yijintang-gamibang mediated by antioxidant effects, were Atractylodis Rhizoma, Citri Pericarpium, Glycyrrhizae Radix, Hordei Fructus Germiniatus, Holelen and Citri Pericarpium. Furthermore Atractylodis Rhizoma and Citri Pericarpium showed more favorable protective effects as compared with omeprazole, therefore, it is expected that Atractylodis Rhizoma and Citri Pericarpium have potential as new alternatives or safe therapeutics against RE.

Objective : Reflux esophagitis is a disease caused by reflux of stomach contents, stomach acid, and pepsin into the esophagus, and is currently increasing worldwide. This study was conducted to evaluate the effect of a mixture of Rhei Rhizoma and Scutellariae Radix (RS) extract on acute reflux esophagitis in rats. Methods : Rats were divided into five groups for examination: Normal group (Nor, n=8), water-treated acute reflux esophagitis rats (Con, n=8), tocopherol 30 mg/kg body weight/day-treated acute reflux esophagitis rats (Toco, n=8), RS 100 mg/kg body weight/day-treated acute reflux esophagitis rats (RS100, n=8), RS 200 mg/kg body weight/day-treated acute reflux esophagitis rats (RS200, n=8). All rats fasted for 18 h and then were derived by linking the metastatic junction between pylorus and forestomach and corpus. And rats were sacrificed 5 h after surgery. We analyzed the expression of NADPH, MAPK, inflammatory, anti-inflammatory, and tight junction related proteins by western blot in esophageal tissue and observed the level of reactive oxygen species (ROS), alanine aminotransferanse (ALT), and aspartate aminotransferase (AST) in serum. Results : RS administration significantly protected the esophageal mucosal damage of reflux esophagitis, and ROS, AST, and ALT levels were significantly reduced in RS administration compared to Con group. In addition, RS administration effectively suppressed MAPK and NF-κB pathways and upregulated protein expressions of tight junction protein. Conclusions : These results suggest that RS protected the esophageal mucosa by inhibiting the MAPK and NF-κB pathways and upregulating tight junctions.

Objectives: The object of this study was to observe the suppressive effects of Yijintang-gamibang (YJGMB), Yijintang being traditionally used in the Korean Medicine for treating various digestive diseases, on the rat reflux esophagitis (RE) as compared with omeprazole, a well-known proton pump inhibitor. Methods: Three different dosages of YJGMB, 50, 100 and 200 mg/kg, were orally pretreated once a day for 28 days before pylorus and forestomach ligation. Seven groups of 8 rats each were used in the study. Six hrs after pylorus and forestomach ligation, changes to the stomach and esophagus lesion areas, gastric volumes, acid and pepsin outputs, invasive lesion percentages, fundic mucosa, esophageal submucosa and total thicknesses were measured by histomorphometry. The results were compared with omeprazole 10 and 30 mg/kg treated groups in which the effects on RE were already confirmed. Results: As results of pylorus and forestomach ligation, marked increases of esophageal and gastric mucosa lesion areas, gastric volumes, acid outputs, pepsin outputs were observed with histopathological changes of RE, such as hemorrhages, ulcerative lesions and edematous changes on the esophageal and fundic mucosa. However, these pylorus and forestomach ligation induced RE were dose-dependently inhibited by treatment of 50, 100 and 200 mg/kg of YJGMB. YJGMB 50 mg/kg showed similar suppressive effects as 30 mg/kg of omeprazole, but more favorable effects were observed as compared with omeprazole 10 mg/kg. Conclusion: The results suggest that YJGMB showed favorable suppressive effects on the RE induced by pylorus and forestomach ligation. It is therefore expected that YJGMB will show favorable effects on RE as corresponds to the suggestion of traditional Korean medicine. However, more detailed mechanism studies should be conducted in future with the screening of the biological active chemical compounds in herbs.

Because Lonicerae Flos has effects of antiinflammatory and antioxidant, we studied an effect of Lonicerae Flos on reflux esophagitis (RE) through those effects. Rats were treated with three different dosages of LF (500, 250 and 125 mg/kg) orally for 14 days before pylorus and forestomach ligation. Six hrs after pylorus and forestomach ligation, we dissected a stomach and examined a stomach volume, gastric acid output, pepsin release in the stomach, total hexose, sialic acid in stomach tissue and histamine contents of sera. The results were compared with an ${\alpha}$-tocopherol (once orally, 1hr before operation, 30 mg/kg) treated group in which the effects on RE were already confirmed. Lonicerae Flos extract (LE) reduced gastric volumes compared to RE control. This indicate that LE protect a stomach mucosa by depressing of gastric acid release and corresponse with a reducing histamine content of serum. And LE decreasd a volume of pepsin in stomach compraed to RE control, LE increased contents of total hexose and sialic acid based on esophageal and gastric mucus. This indicated that an increased mucus by LE protected inflammation of esophagus mucosa and gastric mucosa induced by gastric acid. So, LE suppressed a gasric acid by decreasing a pepsin release in stomach, suppressed an injury of esophagus inducted by gastric acid with increasing esophageal mucus and a minimum dose of LE to RE was 250 mg/kg. The results suggest that antioxidant effects of LF could attenuate the severity of reflux esophagitis and prevent the esophageal mucosal damage, and validate its therapeutic use in esophageal reflux disease.
