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.

This study was carried out to understand the macroscopic aspects of the digestive system symptoms occurring after taking oriental herb complex decoction as observing morphological changes in esophagus, stomach and duodenal bulb by endoscopy of upper gastrointestinal tract when these symptoms developed. The subjects of this study were 46 patients (male 22, female 24, mean age : $54.72{\pm}14.26$ years) who were chosen among ones who took oriental herb complex decoction for medical care and developed symptoms related to the gastrointestinal tract while taking an oriental herb decoction, which were assumed that the digestive symptoms were newly developed because of administration. The subjects were given morphological examination by endoscopy of the upper gastrointestinal tract. As a result of the endoscopy operated due to the digestive symptoms developed during the administration of oriental herb decoction, there were 2 cases of esophagitis, 5 cases of acute gastritis, 1 case of chronic gastritis A type, 15 cases of chronic gastritis B type, 1 case of duodenitis, 1 case of gastric ulcer, 1 case of gastric polyp, 2 cases of intestinal metaplasia, 1 case of gastric ptosis and 17 cases of normal findings which didn't have any abnormality macroscopically with endoscopy. With regards to the patients who complained of the digestive symptoms after taking oriental herb decoction, it has been found that the symptoms occurred as the oriental herbal medicine taken by the patients who had the digestive symptoms at ordinary times influenced on the gastrointestinal tract. Especially, many of them were had chronic gastritis and functional dyspepsia in the past. The disease accompanying macroscopic lesions at endoscopy which occurred due to the oriental herb decoction as direct cause, was acute gastritis, and it was the prescription to cure the pains and inflammations of skeletomuscular disease.

Background: Cancers of gastric and esophagus are the most frequent gastrointestinal (GI) tract cancers in Iran. This study aimed to analyze time trends of GI tract cancers in Guilan province by gender and age to provide solid scientific evidence for cancer prevention and control. Materials and Methods: The data were obtained from the Guilan Cancer Registry System and Guilan Provincial Health Center, over the 15 year period between 1997 and 2011. Crude incidence and age standardized (AS)incidence rates were calculated and annual percent change was estimated by Joinpoint software for long term trend analysis. Results: During the study period, 8,332 cases of GI malignances with a male to female ratio of 1:1.73 were registered in Guilan province. The AS rates for esophageal, gastric, colon and rectal cancers were 5.97, 14.5, 7.59 and 3.58 per 105 respectively. While the trend was declining and relatively constant for esophageal and gastric cancer, respectively, the incidence trend for colon and rectal cancers was of increase over the period of the study. Conclusions: The results indicated that the incidence of GI cancers was relatively low in Guilan province compared to neighboring provinces. An effective cancer control program including prevention measures, early detection and effective treatment needs to be implemented to reduce cancer morbidity and mortality.

Purpose: The most important prognostic factors in gastric cancer is the depth of invasion of the primary tumor and lymph node metastasis. The nodal staging of the 5th edition of the Union Internationale Contrala Cancrums (UICC) TNM classification in 1997 was changed based on the number of metastatic lymph node. We attempted to evaluate the prognostic significance of N2 group metastasis in pT3pN1 gastric cancer patients by comparing two different nodal staging systems. Materials and Methods: A retrospective analysis was made for 352 gastric cancer patients who underwent curative resection, including D2 dissection, from 1991 to 1997 at Asan Medical Center. A clinicopathologic comparison between two groups by using a nodal staging systems was summarized into a table. Cumulative survival rates were calculated by using the Kaplan-Meier method. The difference between the two groups was evaluated by using the log rank test with SPSS 11.5 for Windows Results: There were no statistical differences in clinicopathologic factors. However, there was a significant difference in survival rate between the two groups (P=0.0009). This suggests that N2 group metastasis in pT3pN1 gastric cancer patients has a clinical significance for predicting prognosis. Conclusion: Our results suggest a possibility of prognostic significance of N2 group metastasis. Therefore, anatomical location of the lymph node should be described.

Formalin is a water-soluble, colorless, pungent, irritating and highly reactive gas. A 40% solution of formaldehyde in water, also known as formalin, is used as a disinfectant, antiseptic, deodorant, tissue fixative and embalming fluid. Ingestion can lead to immediate deleterious effects on almost all systems of the body including gastrointestinal tract, central nervous system, cardiovsacular system and hepato-renal system, causing gastrointestinal hemorrhage, cardiovsacular collapse, unconsciousness or convulsions, severe metabolic acidosis and acute respiratory distress syndrome. We treated a 39-year-old woman who ingested 300 ml formalin in a suicidal attempt. Despite hemodialysis, death occurred after 23 h.

An 89-year-old man was referred to our hospital for treatment of hepatolithiasis causing recurrent cholangitis. He had undergone a prior Whipple procedure. Computed tomography demonstrated left-sided hepatolithiasis. First, we conducted peroral direct cholangioscopy (PDCS) using an ultraslim endoscope. Although PDCS was successfully conducted, it was unsuccessful in removing all the stones. The stones located in the B2 segment were difficult to remove because the endoscope could not be inserted deeply into this segment due to the small size of the intrahepatic bile duct. Next, we substituted the endoscope with an upper gastrointestinal endoscope. After positioning the endoscope, the SpyGlass digital system (SPY-DS) was successfully inserted deep into the B2 segment. Upon visualizing the residual stones, we conducted SPY-DS-guided electrohydraulic lithotripsy. The stones were disintegrated and completely removed. In cases of PDCS failure, a treatment strategy using the SPY-DS can be considered for patients with hepatolithiasis after a Whipple procedure.

Intestinal absorption of ${\beta}-lactam$ antibiotics and angiotensin converting enzyme(ACE) inhibitors has been shown to use the carrier-mediated transport system. In vitro experiments have established that the efficacy of uptake by enterocytes depends on an inwardly directed proton gradient. It was suggested that benazepril was mediated by tripeptide transport system and that amoxicillin was transported by dipeptide transport carrier. The aim of this study is to assess the influence of amoxicillin on the intestinal absorption of benazepril using in vitro diffusion chamber and in situ single pass perfusion technique in the rat in order to elucidate whether the above transport systems are competitive or not. We obtained the gastrointestinal pemeability coefficient of amoxicillin, benazepril and both of them using in vitro diffusion chamber. And also the gastrointestinal absorption clearance of amoxicillin, benazepril and both of them using in situ single-pass perfusion method at steady state were calculated. Amoxicillin and benazepril were analyzed by HPLC. The results by the use of diffusion chamber in vitro indicated that the apparent intestinal permeability coefficient of benazepril was significantly(p<0.01) decreased by amoxicillin(45.2%) and vice versa significantly(p<0.01) decreased(89.1%). The results by the in situ gastrointestinal single-pass perfusion method indicated that the intestinal absorption clearance of benazepril was significantly(p<0.05) decreased by amoxicillin (40.2%) and vice versa significantly(p<0.05) decreased(54.8%). These results might suggest that they share the same peptide carrier pathway for oral absorption.

Functionally and physiologically active peptides are produced from several food proteins during gastrointestinal digestion and fermentation of food materials with lactic acid bacteria. Once bioactive peptides (BPs) are liberated, they exhibit a wide variety of physiological functions in the human body such as gastrointestinal, cardiovascular, immune, endocrine, and nervous systems. These functionalities of the peptides in human health and physiology include antihypertensive, antimicrobial, antioxidative, antithrombotic, opioid, anti-appetizing, immunomodulatory and mineral-binding activities.

Chicken is a major food source for humans, hence it is important to understand the mechanisms involved in nutrient absorption in chicken. In the gastrointestinal tract (GIT), the microbiota plays a central role in enhancing nutrient absorption and strengthening the immune system, thereby affecting both growth and health of chicken. There is little information on the diversity and functions of chicken GIT microbiota, its impact on the host, and the interactions between the microbiota and host. Here, we review the recent metagenomic strategies to analyze the chicken GIT microbiota composition and its functions related to improving metabolism and health. We summarize methodology of metagenomics in order to obtain bacterial taxonomy and functional inferences of the GIT microbiota and suggest a set of indicator genes for monitoring and manipulating the microbiota to promote host health in future.
