Sanguisorba officinalis L. has been used as a traditional remedy for arthritis, neuralgia, diarrhea, vomiting, gastric ulcer and gastro-intestinal disorders. This study was performed to investigate the protective effects of ethylacetate fraction of Sanguisorba officinalis L. ethanol extract (SOE) on the gastric mucosal damage and gastric ulcer induced by HCI-ethanol, indomethacin, Shay-ligation method, restraint and water-immersion stress, and cysteamine in rats. The experiment animals were divided into four groups: a negative control group (CON), positive control group (cimetidine 100 mg/kg-CMT or omeprazol 100 mg/kg administrated group-OMT), SOE 200 mg/kg administrated group (SOL) and SOE 400 mg/kg administrated group (SOH), respectively. Rats were given an oral or intraduodenal administration of SOE, and all SOE treatment groups compared with the CON significantly inhibited HCI-ethanol-induced acute gastritis and indomethacin-induced gastric ulcers in dose-dependent manner, of which effects were lower in a positive control drug (CMT). The inhibition rates ($\%$) on the acute gastritis induced by HCI-ethanol and the gastric ulcers induced by indomethacin in rats, 17.66$\%$ and 48.28$\%$ in SOL, 21.71$\%$, and 51.08$\%$ in SOH, and 47.26$\%$ and 58.26$\%$ in CMT compared with CON, respectively, In pylorus ligated rats, the groups of SOE showed decreases in the volume of gastric secretion and acid output. However, no significant differences were observed in the pepsin activity between treated groups . In addition, SOH also depressed gastric ulcers induced by restraint and water-immersion stress and duodenal ulcers induced by cysteamine. These results suggest that Sanguisorba officinalis L. has remarkable antigastric ulcer effects and could be developed as a new antigastric ulcer agents.

Helicobacter pylori is a Gram-negative bacterium which causes chronic gastritis and is associated with gastric ulcer, duodenal ulcer and gastric carcinoma. In the process of screening of antibacterial activities against H. pylori from soil microorganisms, fungus No. 60686 was isolated. After fermentation of No.60686, the antibacterial compound was isolated, purified and followed by extraction of mycelium with organic solvents, acetone and ethyl acetate, through silica gel chromatography, LH-20 gel chromatography and HPLC. As a result of the structural analyses of the compound by IR, $^1$H- and $^{13}$C-NMR, FAB/Mass spectrophotometer, the compound having the antimicrobial activity was identified as chaetoglobosin A ($C_{32}H_{36}N_2O_5$), a cytochalasan derivative. The antimicrobial activity of chaetoglobosin A was tested against Gram-positive and negative bacteria by paper disk method. Among the test strains of 9 Gram-positive bacteria and 18 Gram-negative bacteria containing 4 H. pylori strains, the growth of 4 H. pylori strains and 3 S. aureus strains (SG 511, 285 and 503) was only inhibited by chaetoglobosin A. Also it was shown that its growth inhibition against H. pylori strains was stronger than that against S. aureus strains at the treatment of the same concentration. Therefore it was concluded that chaetoglobosin A has a specific growth inhibition against H. pylori of the tested bacteria.

Objectives : We investigated the characteristics of perceived stress response and relationship between some variables of gastrointestinal symptoms(esp., dyspepsia) and subscales of perceived stress response inventory(PSRI) in patients with upper gastointestinal disorder when they perceived stress. Methods : 84 patients with upper gastrointestinal disorder(gastritis, gastric ulcer, duodenal ulcer etc.) and 94 normal controls completed the PSRI developed by Korean psychiatrists. The patient group performed the questionnaire including some variables of gastrointestinal symptoms. Results : Internal consistency was statistically significant in all subscales of PSRI. The patient group was significantly higher at total score of PSRI, general somatic symptom subscale score, specific somatic symptom score than control group. As the result of stepwise regression analysis for relationship between some variables of gastrointestinal symptoms ans subscales of PSRI, specific somatic symptom subsclae closely related with illness duration, past illness history and severity of symptom, and the lowered cognitive function & general negative thinking subscale related with the existence of emotional distress. Conclusion : Patients with upper gastrointestinal disorder showed stronger perceived stress response than control group and they experiences somatic symptoms related to autonomic nervous system and/or gastrointestinal symtoms rather than emotional, cognitive, behavioral symtoms when they perceived stress. They also responded to stress as they expeirenced specific somatic symtom when they had long illness duration, past illness history, and high severity of symptom and the existence of emotional distress could develop lowered congnitive function and general negative thinking.

Purpose: The aim of this study was to evaluate the clinical characteristics, endoscopic findings and risk factors related to the upper gastrointestinal bleeding (UGIB) seen in full-term infants. Methods: A clinical analysis for 9 cases with UGIB confirmed by endoscopy was carried out retrospectively. Patients were admitted to the Department of Pediatrics, Eulji Hospital, from January to December 2003. Results: UGIB from gastric or duodenal mucosal lesions has been seen in 0.13% in newborns infants. All patients were full-term AGA neonates without asphyxic findings at birth. Hematemesis, melena or recurrent vomiting developed within $4.4{\pm}3.8days$ after birth. Vital sign and laboratory test was normal on admission. Endoscopic findings showed hemorrhagic gastritis in 6 cases and peptic ulcers in 3 cases. All patients were successfully managed by medical treatment for $18.6{\pm}5.0days$. On treatment, clinical symptoms improved within $0.9{\pm}0.3days$. Follow-up endoscopy was not performed because there was no recurrence of symptoms in all patients. Case mothers had no history of gastritis, ulcer or anti-ulcer medications before and during pregnancy. Conclusion: If the healthy full-term infants express UGIB within a few days after birth, it is necessary to take careful history of family, mother and delivery process and to practice endoscopy for mucosal lesions of the patients. A follow-up endoscopy dose not seem to be necessary if the infant is clinically well.

Cimetidine is a histamine $H_2-receptor$ antagonist, used for the treatment of endoscopically or radiographically comfirmed duodenal ulcer, pathologic GI hypersecretory conditions, and active, benign and gastric ulcer. Simple method for determining cimetidine in human plasma has been developed and validated. The analytical procedure for cimetidine showed a linear relationship in the concentration ranges from $0.05\;to\;5\;{\mu}g/ml$. Coefficient of variance (CV, %) for intraday and interday validation and relative error (RE, %) were less than ${\pm}15%$. Based on this analytical method, the bioequivalence of two cimetidine 400 mg tablets, reference (Tagamet 400 mg) and test drug (Sinil CIMETIDINE 400 mg) was evaluated according to the guidelines set by the Korea Food and Drug Administration (KFDA). Release of cimetidine from the tablets in vitro was tested using KP VIII Apparatus II with various dissolution media (pH 1.2, 4.0, 6.8 buffer solutions and water). Twenty-four healthy volunteers, $21.38{\pm}1.86$ years in age and $68.71{\pm}8.68\;kg$ in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was performed. After oral administration of a tablet containing 400 mg of cimetidine, blood samples were taken at predetermined time intervals and concentrations of cimetidine in plasma were determined using HPLC equipped with UV detector. The dissolution profiles of the two tablet formulations were very similar at all dissolution media. In addition, pharmacokinetic parameters such as $AUC_t$ and $C_{max}$ were calculated and ANOVA was employed for the statistical analysis of parameters. The results were revealed that the differences in $AUC_t$ and $C_{max}$ between the two tablets were 4.17 % and 0.97% respectively. At 90% confidence intervals, the differences in these parameters were also within ${\pm}20%$. All of the above mentioned parameters have met the criteria of KFDA guidelines for bioequivalence, indicating that the test drug tablet (Sinil CIMETIDINE tablet) is bioequivalent to Tagamet 400 mg tablet.

Objective : This study was undertaken to determine whether Gamibaegi-eum (BGU) in vitro and in vivo exerts a beneficial effect against cell injury induced by reactive oxygen species (ROS) in the human intestine. Methods : Effects of BGU in vitro on cell injury were examined using Caco-2 cells, cultured human intestinal cell line. Exposure of cells to H₂O₂ induced increases in the loss of cell viability in a time and dose-dependent fashion. Results : BGU prevented H₂O₂-induced cell death and its effect was dose-dependent over a concentration range of 0.05­1%. H₂O₂-induced cell death was prevented by catalase, the hydrogen peroxide scavenger enzyme, and deferoxamine, the iron chelator. However, the potent antioxidant DPPD did not affect H₂O₂-induced cell death. H₂O₂ increased lipid peroxidation, which was inhibited by BGU and DPPD. H₂O₂ caused DNA damage in a dose-dependent manner, which was prevented by BGU, catalase, and deferoxamine, but not DPPD. BGU restored ATP depletion induced by H₂O₂. BGU inhibited generation of superoxide and H₂O₂ and scavenged directly H₂O₂. Oral administration of mepirizole in vivo at a dose of 200mg/kg resulted in ulcer lesions in the stomach and the proximal duodenum. Pretreatment of BGU(0.1%/kg, orally) and catalase (800Units/kg, i.v.) significantly decreased the size of ulcers. Mepirizole increased lipid peroxidation in the mucosa of the duodenum, suggesting an involvement of ROS. Pretreatment of BGU and catalase significantly inhibited lipid peroxidation induced by mepirizole. Morphological studies showed that mepirizole treatment causes duodenal injury and its effect is prevented by BGU. Conclusion : These results indicate that BGU exerts a protective effect against cell injury in vitro and in vivo through antioxidant action. The present study suggests that BGU may playa therapeutic role in the treatment of human gastrointestinal diseases mediated by ROS.

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.

Gunshot wounds are rare in Korea, but they have tended to increase recently. We experienced an interesting case of penetrating gunshot injuries to the cervical spine with migration the fragments of the bullet within the dural sac of the cervical spine, so discuss the pathomechanics, treatment and complications of gunshot wounds to the spine and present a review of the literature. A 38-year-old man who had tried to commit suicide with a gun was admitted to our hospital with a penetrating injury to the anterior neck. the patient had quadriplegia. A Computed tomography (CT) scan and 3-dimensional CT of the spine showed destruction of the left lateral mass and lamina of the 5th cervical vertebra; the bullet and fragments were found at the level of the 5th cervical vertebra. The posterior approach was done. A total laminectomy and removal of the lateral mass of the 5th cervical vertebrae were performed, and bone fragments and pellets were removed from the spinal canal, but an intradurally retained pellets were not totally removed. A dural laceration was noted intraoperatively, and CSF leakage was observed, so dura repair was done watertightly with prolene 6-0. The dura repair site was covered with fibrin glue and Tachocomb$^{(R)}$. Immediately, a lumbar drain was done. Radiographs included a postoperative CT scan and X-rays. The postoperative neurological status of the patient was improved compared with the preoperative neurological status. however, the patients developed symptoms of menigitis. He received lumbar drainage(200~250 cc/day) and ventilator care. After two weeks, panperitonitis due to duodenal ulcer perforation was identified. Finally, the patient died because of sepsis.

The aim of this study was to evaluate the anti-helicobacter activity of the ethanol extract of Sohamhyoongtang (Coptidis Rhizoma, Pinelliae Tuber and Trichosanthis Semen) and Coptidis Rhizoma total alkaloids, which is one of the components of Sohamhyoongtang. Crude ethanol extract of Sohamhyoongtang (ESHHT) and Coptidis Rhizoma total alkaloids (CRTA) were used for this experiment. Five different types of H. pylori (including H. pylori 26695) were used as test strain. To determine anti-helicobacter activity, minimum inhibitory concentration (MIC) was determined by agar dilution method. The effect of ESHHT and CRTA on the gene expression of H. pylori was investigated by quantitative realtime-PCR (qRT-PCR). MICs of ESHHT against five H. pylori strains were $250{\sim}500{\mu}g/ml$ and MICs of CRTA against five H. pylori strains were $50{\sim}200{\mu}g/ml$. Four representative virulence genes of H. pylori, cagA, ureA, ureB and ureI were tested as target genes for qRT-PCR. According to the qRT-PCR results, both ESHHT and CRTA markedly repressed the expression of cagA gene of H. pylori 26695 (6.91 and 20 folds respecively). These results showed that the ESHHT and CRTA demonstrated antihelicobacter properties, suggesting their potential use in gastritis or duodenal ulcer.

Bezoars are collections or concretions of indigestible foreign material that accumulate and coalesce in the gastrointestinal tract; they usually occur in patients who have undergone gastric surgery and have delayed gastric emptying. Treatment options include dissolution with enzymes, endoscopic fragmentation with removal or aspiration, and surgery. Recently, the efficacy of nasogastric lavage or endoscopic infusion of Coca-Cola for the dissolution of phytobezoar have been reported. We report a case of phytobezoar successfully treated by oral administration and endoscopic injection of Coca-Cola. A 62-year-old woman was referred to Yeungnam University Hospital for epigastric pain. Upper gastrointestinal endoscopy revealed one very large, dark-greenish, solid bezoar in the stomach with gastric ulcer and duodenal bulb deformity. We performed endoscopic injection of Coca-Cola into the bezoar. The patient was instructed to drink four liters of Coca-Cola per day. At endoscopy two days later, the phytobezoar was easily broken into pieces. At endoscopy on the $11^{th}$ day of admission, the phytobezoar was decreased in size and removed by endoscopic fragmentation with a polypectomy snare. At follow up endoscopy after 13 days, the bezoar was completely dissolved.
