Paeoniae Radix has been used as a traditional medicine for various diseases including hepatic disease. However, the inhibitory effect of Paeoniae Radix on intestinal inflammation has not been fully understood yet. The aim of this study was to evaluate the effect of Paeoniae Radix on colitis induced by dextran sulfate sodium in mice. To investigate the protective effects of Paeoniae Radix, the colitis mice were induced by drinking water containing 5% dextran sulfate sodium for 7 days. Mice were randomized into groups receiving Paeoniae Radix (100 mg/kg), sulfasalazine (150 mg/kg) as a positive control, or water as a negative control. We evaluated the effects of Paeoniae Radix on clinical signs induced by dextran sulfate sodium, measuring weight loss, colon length, and disease activity index. Additionally, to find a possible explanation for the anti-inflammatory effects of Paeoniae Radix, we evaluated the effects of Paeoniae Radix on the interleukin-6 and cyclooxygenase-2 levels in colitis tissue. The results indicated that mice treated with dextran sulfate sodium showed measurable clinical signs, including weight loss and reduced colon length. However, Paeoniae Radix treatment significantly improved the weight loss and disease activity index as clinical symptoms. Moreover, Paeoniae Radix inhibited the interleukin-6 and cyclooxygenase-2 expression levels in colon tissues treated with dextran sulfate sodium. Taken together, the findings of this study suggest that Paeoniae Radix may be useful for treating intestinal inflammation, including ulcerative colitis.

Toxic megacolon is a fatal complication of inflammatory or infectious bowel disease. Prognosis depends on the severity of the disease. In cases of poor prognosis, clinical outcomes range from intestinal resection to death, so early diagnosis and appropriate treatment are very important. However, the prevalence of toxic megacolon in children is very low, and in those without underlying diseases such as inflammatory bowel disease, early diagnosis may be delayed. A previously healthy 12-year-old boy presented to our hospital with lower abdomen pain, fever, and hematochezia. Despite antibiotic therapy, the symptoms worsened. On the third day, abdominal computed tomography revealed severe dilatation of the transverse colon, which indicated toxic megacolon. Stool culture was positive for Salmonella enteritidis group D, and rectal endoscopy showed no signs of inflammatory bowel disease. Ceftriaxone and intravenous methylprednisolone were administered, and the patient's condition improved without any complications. We report a case of toxic megacolon as a complication of infectious colitis caused by S. enteritidis group D, which was diagnosed using early imaging and successfully treated without surgical intervention.

Purpose : Children with acute colonic diverticulitis(ACD), can be misdiagnosed with acute appendicitis. Methods : We reviewed 15 cases of ACD during five years, from January 1998 to June 2002 retrospectively. Results : Most patients(80%) with ACD in children presented with right lower quadrant pain. The primary diagnosis on admission was mostly acute appendicitis(87%), and all ACD in children occurred in the right colon. Fourteen patients were managed by conservative treatment including antibiotics. A follow-up study was performed in 15 patients. There were symptomatic recurrences in two patients, but no significant complication was noted. The frequency of ACD was 11.7 per 1000 acute appendicitis. Conclusion : ACD in children can mostly be cured by conservative treatment. It is prudent to choose the management through the diagnostic work up, including abdominal sonography and computed tomography, because there was no significant difference of clinical findings between ACD and acute appendicitis.

We present a case of a colonic involvement associated with necrotizing pancreatitis, with a review of the literature. A 10 year old boy had an appendectomy at the local clinic ten days ago. On admission, he complained nausea, vomiting and severe constipation. His abdomen was distended and he had tenderness on the left abdomen. Laboratory and radiologic studies revealed findings consistent with acute pancreatitis with colonic complication. He was treated conservatively for 30 days but did not improve. On hospital 30th day, abdominal pain developed and his vital sign changed. Abdominal CT suggested ischemic change of the transverse colon. At laparotomy, the left colon showed stenosis. The greatly distended transverse colon was resected and a transverse end colostomy was done. He was discharged at postoperative 45th day with improvement and colostomy closure was performed 8 months later.

Purpose : For the early diagnosis of Henoch-Schonlein purpura(HSP) presenting with acute abdominal pain preceding skin rash. Methods : The clinical, endoscopic and radiological records of 23 cases of HSP, presenting with gastrointestinal symptoms preceding skin rash were reviewed. Results : The intervals from the onset of abdominal pain to the development of the skin rash were one day to 30 days(median five days), most of them were within two weeks. The presenting abdominal symptoms were abdominal pain(23 cases), vomiting(16 cases), hematochezia or melena(eight cases) and hematemesis(three cases). The abnormal endoscopic findings include coalescing erythematous lesions, areas of submucosal hemorrhage and superficial erosions and ulcers. The upper gastrointestinal endoscopy showed the abnormalities in 21 of 23 cases, which were observed in the duodenum( 21 cases), the stomach(12 cases) and the esophagus(one case). Duodenitis with hemorrhage and/or erosions in the descending duodenum was the sole endoscopic abnormality in two cases and was the most marked finding in three cases. Sigmoidoscopy showed the abnormalities in six of eight cases. The abdominal ultrasonogram showed abnormalities in 12 of 17 cases, which included small bowel wall thickening(eight cases) and intramural hemorrhage(three cases). Recurrences after three months of symptom free intervals developed in four cases; three of them had persistent nephritis beyond one year. Conclusion : The erosive hemorrhagic duodenitis in the descending duodenum in the upper endoscopy and the small bowel wall thickening in the abdominal ultrasonogram can be useful findings in the diagnosis of HSP presenting with acute abdomen.

The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and combination with herbal medicine on dextran sodium sulfate (DSS)-induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n = 9): group I-normal group, group II-DSS control group, group III-DSS + sulfasalazine (30 mg/kg), group IV-DSS + sulfasalazine (60 mg/kg), group V-DSS + sulfasalazine (30 mg/kg) + Radish Extract mixture (30 mg /kg) (SRE). DSS-treated mice developed symptoms similar to those of human UC, such as severe bloody diarrhea and weight loss. SRE supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SRE treatment significantly reduced the expression of pro-inflammatory signaling molecules through suppression both MAPK) and nuclear factor-kappa B (NF-${\kappa}B$) signaling pathways, and prevented the apoptosis of colon. Moreover, SRE administration significantly led to the up-regulation of anti-oxidant enzyme including SOD and Catalase. This is the first report that Radish extract mixture combined with sulfasalazine protects against experimental UC via the inhibition of both inflammation and apoptosis, very similar to the standard-of-care sulfasalazin.

Recently we operated on two cases of PDA in premature infant. In both cases, indomethacin therapy had failed to close the PDA. The extremely small baby(body weight 540gm) died 28hrs postoperatively by unexpe ted intrathoracic bleeding probably due to coagulopathy related to septic condition and thrombocytopenia. The clinical course of the second case(body weight 1395gm) was complicated by ileal perforation sec- ondary to necrotizing enterocolitis. The baby underwent segmental resection of ileum with ileostomy on the 8th hospital day. On the 34th hospital day surgical closure of the PDA was done and the ile'ostomy was repaired simultaneously. Ventilator weaning was possible on the postoperative 6th day. The baby discharged on the postoperative 33th day with the body weight of 2050gm.

This study was carried out to improve quality and increase anticancer effect of baechu kimchi by changing various kinds of salt. The baechu cabbages were brined with purified salt (P), natural sea salt (NS), natural sea salt without bittern (NS-B) or baked (Guwun) salt (G) and mixed with other ingredients. Thereafter, the kimchis were fermented for 7 days at $15^{\circ}C$. The changes in pH and acidity of the P and G kimchis were slower than those of NS and NS-B kimchis. NS-B and G kimchis promoted the growth of Leuconostoc sp.; however, it inhibited the growth of Lactobacillus sp. when compared with P and NS brined kimchis. The sensory evaluation results indicated that NS-B and G kimchis were better than P and NS kimchi in taste, color and overall acceptability. Rheological property of texture (cutting strength) of NS-B and G brined kimchis was also much better. Anticancer effects of the kimchi juices and methanol extracts were investigated on AGS human gastric adenocarcinoma cells and HT-29 human colon carcinoma cells by MTT assay. NS-B and G kimchis significantly retarded the growth of both cancer cells compared to P and NS kimchis. From these results, kind of salt is very important when kimchi is prepared. It proved that removing bittern from natural sea salt is good ancient tradition when brining the cabbage. Using the baked salt is also a better method to improve the quality and anticancer effect of kimchi.
