Nephrolithiasis is the most common disorder of the urinary tract in hospitalized patients, more frequently increased in 30~50 years of age, more common in males than in females, prior right stone to left side, and than upper ureteral stone is found in cultural country, while lower ureteral stone is increased in uncultural country. Stone components are classified as calcium oxalate, calcium phosphate, magnesium ammonium phosphate, uric acid, cystine, and their mixed stone, respectively. According to the pathophysiology of urinary stones, supersaturation/crystalization of inorganic salt concentration in urine, organic matrix, inhibitor deficiency, and epitaxy theory could be based on the stone formation. Not only hypercalciuria, hyperparathyroidism, hyperoxaluria, hyperuricosuria, and cystinuria, but also renal tubular acidosis, hypervitaminosis D, and peptic ulcer, are significantly associated with nephrolithiasis. In this study upper ureteral stone component were analyzed with chemical analysis, infrared spectrum, and image analyzer from K43 patient wit erosive gastritis. As the results, mixed stone of calcium oxalate dihydrate and calcium phosphate apatite was identified, the values of clinical test in blood and urine maintained normal revels. The relapsing urinary stone from K43 have no correlation between factors for stone formation reported early, also have no evidence for risk from erosive gastritis.

This Study evaluated the inhibitory action of $luteolin-7-O-{\beta}-D-glucuronopyranoside$, luteolin which was isolated from Salix gilgiana leaves, and omeprazole on reflux esophagitis and gastritis in rats. Reflux esophagitis and gastritis were induced surgically and by the administration of indomethacin, respectively. The intraduodenal administration of $luteolin-7-O-{\beta}-D-glucuronopyranoside$ decreased the ulcer index, injury area, gastric volume and acid output, and increased the gastric pH compared with luteolin. $Luteolin-7-O-{\beta}-D-glucuronopyranoside$ significantly decreased the size of the gastric lesions that had been induced by exposing the gastric mucosa to indomethacin. The malondialdehyde content, which is the end product of lipid peroxidation, was increased significantly after inducing of reflux esophagitis. The malondialdehyde content was decreased by $Luteolin-7-O-{\beta}-D-glucuronopyranoside$ but not luteolin or omeprazole. $Luteolin-7-O-{\beta}-D-glucuronopyranoside$ has a more potent antioxidative effect than luteolin. $Luteolin-7-O-{\beta}-D-glucuronopyranoside$ is a promising drug for the treatment of reflux esophagitis and gastritis.

Two dogs (Case 1: Poodle, 4 years old, spayed female; Case 2: Bulldog, 3 years old, intact female) were referred to us for treatment of vomiting; Case 1 had a history of acute vomiting that started 1 day prior to presentation, and Case 2 had a history of chronic vomiting that started 2 years prior to presentation. The vomiting did not respond to medication in the local animal hospital. Results from abdominal ultrasound examinations showed that case 1 had gastric wall thickening, and case 2 had no remarkable findings. For both cases, we performed gastrointestinal endoscopic examinations, and several biopsy samples were obtained from different gastric areas. On the basis of the results of histopathological examinations, both dogs were diagnosed with atrophic gastritis concurrent with a Helicobacter infection. Clinical signs improved after antibiotic therapy. This case report describes the clinical, endoscopic, and histopathological findings of atrophic gastritis concurrent with a Helicobacter infection.

Objectives : Pyeongwi-san is widely used in Korean medicine for acute indigestion or gastrodynia. As a therapeutic agent for digestive diseases of modern people, in order to confirm the mechanism of Pyeongwi-san on digestive tract disease and the difference of therapeutic efficacy between its formulation, a comparative efficacy test was conducted on digestive tract disease animal model. Methods : For LPS enteritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san, and then intraperitoneally administered LPS one hour later to induce enteritis. After 5 hours, blood was collected and TNFα, IL-1β, IL-6 and PGE2 were confirmed by ELISA. For acute gastritis animal model, male SD rats were intraorally treated with different formulation types of Pyeongwi-san according to the prescribed concentration, and then intraorally administered 60% ethanol and 150 mM HCl one hour later to induce acute gastritis. After 5 hours, blood was collected and TNFα,IL-6 were confirmed by ELISA. Results : In the LPS-administered enteritis animal model, Pyeongwi-san decreased TNFα, IL-1β, PGE2 and especially IL-6. Pyeongwi-san also decreased IL-6 in acute gastritis animal model. In addition, there was no significant difference in efficacy between the two formulations when compared with inflammatory markers. Conclusions : The efficacy of Pyeongwi-san was confirmed in the inflammatory markers related to digestive inflammatory diseases, and the efficay between two formulations of Pyeongwi-san was relatively similar. Further studies are needed to investigate the new applicability of Pyeongwi-san on different inflammatory diseases that have similar inflammation markers identified in this experiment.

Background: There are various Helicobacter species colonizing the stomachs of animals. Although Helicobacter species usually cause asymptomatic infection in the hosts, clinical signs can occur due to gastritis associated with Helicobacter in animals. Among them, Helicobacter pylori is strongly associated with chronic gastritis, gastric ulcers, and gastric cancers. As the standard therapies used to treat H. pylori have proven insufficient, alternative options are needed to prevent and eradicate the diseases associated with this bacterium. Cheonwangbosim-dan (CBD), a traditional herbal formula that is popular in East Asia, has been commonly used for arterial or auricular flutter, neurosis, insomnia, and cardiac malfunction-induced disease. Objectives: The present study investigated the antimicrobial effect of CBD on H. pylori-infected human gastric carcinoma AGS cells and model mice. Methods: AGS cells were infected with H. pylori and treated with a variety of concentrations of CBD or antibiotics. Mice were given 3 oral inoculations with H. pylori and then dosed with CBD (100 or 500 mg/kg) for 4 weeks or with standard antibiotics for 1 week. One week after the last treatment, gastric samples were collected and examined by histopathological analysis, real-time quantitative polymerase chain reaction, and immunoblotting. Results: Our results showed that CBD treatment of AGS cells significantly reduced the H. pylori-induced elevations of interleukin-8, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2). In the animal model, CBD treatment inhibited the colonization of H. pylori and the levels of malondialdehyde, inflammation, proinflammatory cytokines, iNOS, and COX-2 in gastric tissues. CBD also decreased the phosphorylation levels of p38 mitogen-activated protein kinase family. Conclusions: This study suggests that CBD might be a prospective candidate for treating H. pylori-induced gastric injury.

The objective of this study was to make a comparison between chronic superficial gastritis and gastric ulcer patients regarding stress responses, anger expression and alexithymia. The subjects included 100 patients with chronic superficial gastritis and 40 patients with gastric ulcer confirmed by gastroscopy. Stress responses were measured by the Stress Response Inventory(SRI) and anxiety, depression, somatization and hostility subscales of the Symptom Checklist-90-revised(SCL-90-R). Anger expression and anger suppression were assessed by the Anger Expression Scale. The level of alexithymia was assessed by the Toronto Alexithymia Scale(TAS). Multiple regression analysis showed that the patients with chronic gastritis scored significantly higher on tension subscale and somatization subscale of the SRI, and anxiety subscale of the SCL-90-R than those with gastric ulcer. However, no significant differences were found in the score of anger expression and anger suppression subscales and total score of TAS between the two groups. In chronic gastritis patients, women scored significantly higher on somatization subscale of the SRI than men, whereas in gastric ulcer patients, men scored significantly higher on somatization subscale of the SRI than women. These results suggest that chronic gastritis patients are more likely to have higher level of stress responses and higher susceptibility to stress than gastric ulcer patients. In addition, in chronic gastritis patients, women are more likely to somatize than men, but in gastric ulcer patients, men are more likely to somatize than women. However, there were no differences between the two groups in anger expression, anger suppression and alexithymia.

Purpose: Nodular gastritis is a characteristic finding of Helicobacter pylori infection in children. The aim of this study was to evaluate the difference in gene expression in the gastric mucosa of H. pylori-infected and non-infected children, and to analyze the difference in gene expression using cDNA microarray analysis of nodular gastritis caused by H. pylori infection. Methods: Twelve children (6 boys and 6 girls; mean age 9.8 years) who underwent upper gastrointestinal endoscopy and biopsy at Seoul National University Bundang Hospital were included in the study. The subjects were divided into three groups according to the presence of H. pylori infection and nodular gastritis on endoscopic examination. Gastric mucosa tissue was kept at $-70^{\circ}C$ and RNA was extracted to perform cDNA microarray analysis in each patient. Results: cDNA microarray analysis in children revealed a clear distinction between H. pylori-infected and non-infected gastric mucosa. Specifically, 182 over-expressed genes and 29 under-expressed genes were identified in H. pylori-infected gastric mucosa compared to non-infected mucosa. H. pylori-infected nodular gastritis revealed different gene expression patterns from H. pylori-infected normal gastric mucosa; five genes were over-expressed and five genes were under-expressed. Conclusion: In the presence of H. pylori infection, gastric mucosa shows distinct differences in gene expression, and nodular gastritis with H. pylori infection in children may be associated with over- or under-expression of some genes. Further studies are required to clarify the host response and the pathogenesis of nodular gastritis in children.

In the previous study, we demonstrated that ginsenoside $Rb_1$ isolated from the butanol fraction of the head of Panax ginseng had significant gastroprotective activity on gastritis and gastric ulcer models in rats. It has been well established that drugs to have capacity of scavenging or inhibiting the generation of reactive oxygen radicals prevent the gastric mucosal injury. Ginsenoside $Rb_1$ was tested on HCl ethanol-induced gastritis in rats, DPPH-induced free radical scavenging effect, MDA assay, GSH activity, and SOD activity in gastric tissue. It showed significant inhibition in HCl ethanol-induced gastritis, and al~o significantly increase of GSH activated SOD. We speculate that the protective effect of ginsenoside $Rb_1$ against HCl ethanol-induced gastric mucosal damage is originated from the increase of GSH and the activation of SOD.

Roots of Astragalus membranaceus (A. membranaceus) (Astragali Radix, AR) has been used as a herbal medicine for gastrointestinal disorders in China, Korea, Japan, and other Asia countries. In this study we investigated the effects of the AR 70% ethanol extract and compounds isolated from AR on gastritis in rats and growth of human gastric cancer cells. AR 70% ethanol extract showed the potent acid-neutralizing capacities and partly cytotoxicity of Helicobacter pylori and human AGS gastric cancers cell. Astragaloside I and daucosterol, which were isolated from AR, significantly inhibited HCl/ethanol-induced gastric lesions. In addition, daucosterol increased the mucus content to almost the same as the positive control. The results of this study suggest that astragaloside I and daucosterol may be good candidates for the development of new drugs or neutraceuticals which can be used for the treatment or prevention of gastritis.

Cirsium japonicum var. ussuriense (CJ) is used as a folk medicine for diuretic, arthritis, dyspepsia, and bleeding in Korea. Until now, more than fifteen kinds of CJ were identified and among them, Cirsium japonicum var. nakaianum Nakai was selected as experimental material. Both that from The Medical Herb Garden of Seoul National University located at Gayang-dong, Koyang city and native that from a hillock near Dangjin, Chungnam were collected and analyzed to determine whether it is varied in efficacy on their habitats. Extracts and fractions of CJ had a strong effect of antibacterial activity on H. pylori and antioxidant effects. And the CJ from Garden and Dangjin were showed to be more efficient in acute gastritis through the HCl${\cdot}$ethanol-induced gastric lesion test and chronic gastritis through the indomethacin-induced gastric lesion test, respectively. This study proved that the effects of CJ are varied by their habitats. Also, these results suggest that the CJ has potentials for use as functional food and medicine.
