Purpose : Acute gastroenteritis is a frequent childhood disease. The purpose of this study is to determine if certain pathogens are related to more severe clinical disease in children with acute gastroenteritis. Methods : Two hundred seventy one stool samples were obtained from pediatric patients with acute gastroenteritis that was associated with virus, bacteria and protozoa infection between January 2006 and December 2006. The clinical severity was assessed by using the 24 point scale Clark score. We evaluate the Clark score according to the pathogens. Results : One hundred thirty seven children were noted to have virus, bacteria or protozoal infection. Rotavirus was the most common pathogen found in the children with gastroenteritis (20.6%). Other frequent pathogens were norovirus (10.7%) and E. coli (12.9%). Vomiting (P=0.049) and diarrhea (P=0.003) symptoms were more frequent in the rotavirus group than that in the rotavirus negative group. There were no statistical differences in the Clark score between the virus positive group and the virus negative group. Conclusion : We concluded that rotavirus was the most common pathogen in children with gastroenteritis, yet the clinical severity was not dependent on the presence of viral or bacterial pathogens.
Purpose: Palliative procedures or surgical interventions not only manage various symptoms of malignant gastrointestinal obstruction, but also improve the quality of life. We investigated the clinical characteristics and prognostic factors of terminal cancer patients with palliative procedures for malignant gastrointestinal obstruction. Methods: We retrospectively reviewed the medical records of 48 terminal cancer patients with palliative procedures for malignant gastrointestinal obstruction at Sam Anyang hospital from May in 2002 to May in 2005. We excluded patients with palliative tumor resection. We analyzed prognostic factors in symtom-free survival and overall survival using Kaplan-Meier method, univariate and multivariate analysis. Results: There were 25 males (52%) and 23 females (48%), and median age of 48 patients was 65 years. The most common cause of malignant gastrointestinal obstruction was colorectal (26 patients, 55%), followed by stomach (10, 21%). Twenty patients (42%) received previous treatment (chemotherapy, surgery, and radiotherapy) and 28 (58%) never received any. Eighteen of 20 had received chemotherapy. The most common symptom was pain (15 patients, 31%). Twenty three patients (48%) had Eastern Cooperative Oncology Group(ECOG) performance status of 1 or 2 score and 25 patients (52%) 3 or 4 score. The most common palliative procedure was colostomy and there was no mortality concerning the palliative procedures. By univariate and multivariate analysis, performance status was the only independent prognostic factor in overall survival and symptom-free survival. Overall survival was 150 days and symptom-free survival was 90 days. Conclusion:. We confirmed that perftatdormance status is significant independent prognostic factor in terminal cancer patients with palliative procedures for malignant gastrointestinal obstruction.
The objective of this study is to investigate the anti-Helicobacter pylori and anti-cancer activities of the live cells (LC), cell-free culture supernatants (CFCS), and bacteriocin solution (BS) obtained from Lactobacillus acidophilus BK13 and Lactobacillus paracasei BK57 strains. After incubation for 30 h in MRS broth, the concentration of lactic acid produced by L. paracasei BK57 ($155.9{\pm}10.2mM$) was higher than in MRS broth using L. acidophilus BK13 ($126.8{\pm}7.9mM$). Maximum bacteriocin activity (128 AU/ml) of BK13 strain was observed after 30 h of cultivation at $37^{\circ}C$, however its magnitude was significantly lower than that of BK57 strain (256 AU/ml). The LC of L. acidophilus BK13 and L. paracasei BK57 were able to inhibit the growth of H. pylori ATCC 43504 at different incubation times, depending on the initial inoculum of the LAB. These CFCS and BS obtained from BK13 and BK57 strains dramatically inhibited the growth, adhesive ability, and enzymatic activity of H. pylori. Meanwhile, the anti-cancer effect of the lactic acid from L. acidophilus BK13 and L. paracasei BK57 strains on AGS cells had significant differences with the control group. Therefore, these antagonistic substances-producing strains are potentially useful as new potential antimicrobial agents for the management and prevention of H. pylori infections.
Mongolian dandelion (Taraxacum mongolicum H.) extracted with solvents having different polarities were prepared to investigate protection activity of gastric mucosa. Ethanol extracts were successively reextracted with methylene chloride, and n-butanol. Concentrations of total flavonoids and luteolin in n-butanol extracts were 27.75 and 1.14%, respectively, much higher than those of other solvent extracts. Results of anti-microbial acitivity test against Helicobacter pylori and urease inhibition test revealed n-butanol extract exerted higher inhibition (13.16%) than other solvent extracts. Based on 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, n-butanol extract showed the highest efficiency of free radical-scavenger activity among the extracts ($SC_{50}\;47{\mu}g/mL$). Erythrocytic photohemolysis tests, for the protection of cell membrane showed that half-life of human erythrocytes was increased by the addition of n-butanol extract $({\tau}_{50}=172min;C=5.0{\mu}g/mL)$. These results indicate n-butanol extract of Mongolian dandelion may be useful as a adjuvant for gastric diseases.

The present experiment was intended to determine the effect of pollen load on chloroform-induced hepatic and renal damage in rats. The subjects were administered with the graded concentration of chloroform and an additional amount of pollen to some groups, and the result of which was: 1. The content of total lipid in liver and kidney increased in proportion to the chloroform concentration, but decreased in the chloroform and pollen administration groups. 2. The amount of total cholesterol in serum, liver and kidney of the chloroform administration group was higher than that of the control group, and it decreased gradually with pollen administration. 3. The activity of sGOT, sGPT, and LDH increased in proportion to the chloroform concentration, but decreased in the pollen-treated groups. 4. It is not significant that the cellulose acetate electrophoresis of LDH isozymes showed the increased of $LDH_5$ in liver of the pollen administration group. LDH isozymes in kidney are not significantly changed, too.
The conventional histochemical stains were used to study the properties of mucosubstances of the intestine in four teleostean species, i. e., Agramus agramus, Inimicus japonicus, Epinephelus chlorostigma, and Helicolenus dactylopterus, all belonging to the order Perciformes. The following methods were used; periodic acid Schiff (PAS), alcian blue (AB) pH at 2.5, AB pH at 1.0, AB pH at 2.5-PAS, and aldehyde fuchsin (AF) pH at 1.7-AB pH at 2.5 stain. The mucosal folds of intestines show differences in species and regions. Widely distributed in all portions studied, goblet cells situated between cylinderical epithelial cells are round or ovoid in shape. They were most densely distributed in distal intestine. In the middle and. distal intestine of Epinephelus chlorostigma and all regions of intestines of Agramus agramus, Inimicus japonicus, and Helicolenus dactylopterus, the presence of both acidic and neutral mucin was confirmed. The property of acidic mucosubstance was sialomucin. Neutral mucin was only encountered in the proximal intestine of Epinephelus chlorostigma. The amount and property of mucin showed differences in species and regions. In the distal intestine of Inimicus japonicus, the amount of acidic mucin is similar to that of neutral mucin. In all regions of intestine of Agramus agramus, proximal and middle intestine of lnimicus japonicus, middle and distal intestine of Epinephelus chlorostigma, and distal intestine of Helicolenus dactylopterus, acidic mucin occured more frequently than neutral mucin. The proximal and middle intestine of Helicolenus dactylopterus have more neutral mucin than acidic mucin.
Purpose: A new classification of gastrointestinal food allergy was published, but the changes of terminology between previously reported terms and the new ones were in a state of disorder. This has resulted in confusion between medical communication and diagnostic and therapeutic approaches. The clinical observations of infants presenting with gastrointestinal cow milk allergy (GI-CMA) were performed, and the changes in the terminology reviewed through the published Korean literature. Methods: Between March 2003 and July 2003, data from 37 consecutive infants with GI-CMA, aged 2 weeks to 15 months, were reviewed. The challenge and elimination test of cow milk, and the endoscopic and histologic findings, were used for the seven subdivisions of GI-CMA according to a new classification on the basis of patients' ages, clinical manifestations and location of gastrointestinal lesions. Results: The 37 patients had a mean age of $5.4{\pm}4.8$ months, with those observed in 26 (70.3%) of patients being below 6 months of age. The seven final diagnoses were; cow milk protein-induced enterocolitis (CMPIE) in 12 (32.4%), cow milk protein proctitis (PROC) in 12 (32.4%), IgE-mediated (IGE) in 6 (16.2%), gastroesophageal reflux-associated cow milk allergy (GERA) in 5 (13.5%) and eosinophilic gastroenterocolitis in 2 (5.4%). CMPIE was revealed as the typical type in 7 (18.9%) and the atypical type in 5 (13.5%), and all of typical CMPIE revealed cow milk protein-induced enteropathy. The mean age at symptom onset was $4.3{\pm}0.8$ months, and for those with typical and atypical CMPIE, and PROC and GERA were $3.8{\pm}4.6$, $10.4{\pm}3.8$, $3.4{\pm}3.9$ and $7.8{\pm}5.7$ months, respectively (p<0.05). The period from onset of symptom to diagnosis was $2.4{\pm}3.3$ (0.5~12) months, with those observed in atypical CMPIE and GERA being over 3months. Although the birth weights in all patients were within the 10~90 percentile range, the body weights on diagnoses were below the 3 percentile in 48.6%; IGE 16.7%, EOS 0%, typical CMPIE 85.7%, atypical CMPIE 60.0%, PROC 25.0% and GERA 100% (p<0.05). Through the review of the Korean literature, 8 case reports and 14 original articles for GI-CMA were found. Conclusion: GI-CMA is not a rare clinical disorder and is subdivided into seven categories on the basis of the patient's age, clinical manifestations and location of the gastrointestinal lesions. The terms for GI-CMA are changing with new classifications, and careful approaches are necessary for medical communications.
Purpose : Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP) is a systemic vasculitis, characterized by cutaneous palpable purpura, gastrointestinal(GI) symptoms, arthritis and renal involvement. In general, the prognosis is determined by GI complication as well as the severity of nephritis. In this study, we analyzed the statistical relationship between the GI symptom and other clinical findings for assessing the prognosis, and evaluated abdominal ultrasonographic findings for early diagnosis of this disease with atypical clinical presentation and early detection of serious GI complications. Methods : One hundred seventy seven patients with HSP in the Department of Pediatrics, Wonkwang University Hospital from January 1994 to June 2004, were enrolled. We retrospectively analyzed charts about clinical and abdominal ultrasonographic findings, and classified our patients into two groups(GI-Sx(-), GI-Sx(+)) for statistical analysis. Results : The ratio of female to male is 1.5 : 1. The peak age incidence was five to eight years in 95 cases(53%). The GI symptoms appeared in 117 cases(66%), which include abdominal pain 115 (98 %), tenderness 45(38%), nausea and vomiting 35(30%), bloody stool 10(8.5%), diarrhea four(3.4%), rebound tenderness four(3.4%), and also intussusception and appendicitis were complicated in five and two cases respectively. GI-Sx(+) group had an increased risk of renal involvement and relapse than the GI-Sx(-) group. But there were no relationships about sex and age incidence, or other clinical and laboratory findings between two groups. Ultrasonographic findings in 98 patients with GI symptoms included small bowel thickening in 70 cases(71%) in which duodenum, jejunum and ileum were involved in 71%, 45.7%, 40% respectively, small bowel dilatation in 41 cases(42%), lymph node swelling in 46 cases(47%), and ascites in 25 cases(25.5%). Conclusion : GI symptoms in patients with HSP suggested increased risk of renal involvement and relapse. Abdominal ultrasonography could be helpful in the early diagnosis on atypical clinical presentation and early detection of serious GI complication in these patients.

Purpose : This study was performed to characterize clinical features of benign convulsions with gastroenteritis(CwG) in infants. Methods : We reviewed clinical features of 67 episodes in 64 patients with afebrile seizure accompanied gastroenteritis admitted to Dept. of Pediatrics Bundang CHA hospital from January 2001 to June 2004. Patients with meningitis, encephalitis/encephalopathy or apparent history of epilepsy were excluded. Results : There were 32 boys and 35 girls. The age of onset ranged from 1 to 42 months($18.5{\pm}6.1$ months). The number of children admitted to the hospital with acute gastroenteritis was 2,887 in the same period. The percentage of patients with CwG was 2.3. Seizure type was exclusively generalized tonic or tonic-clonic seizure. The average number of seizures during a single episode was 3.1 (range, 1-13). Two or more seizures occurred in 53(79.1%) of the 67 episodes. Antiepileptic drugs were administered for 42 episodes. Seizure did not cease after the administration of one kind of antiepileptic drug in 23 episodes(54.7%). The seizures were rather refractory to initial antiepileptic treatment. There were no abnormalities in serum biochemistry test including glucose and electrolytes. Cerebrospinal fluid was normal in all 54 episodes. Stool cultures were negative in 49 episodes. Rotavirus was positive in stools in 51(82.3%) of 62 episodes. Norovirus was positive in stools in 2 episodes and astrovirus in 1 of 18 episodes. CT and/or MRI were performed in 15 cases and demonstrated no neuroradiologic abnormalities. Of 73 Interictal EEG, initial 24 cases showed occasional spike or sharp wave discharges from the mid-line area during stage I-II sleep, which were apparently differentiated from vertex sharp transient or K-complexes. The mean follow-up period was 5.7 months(1-36 months). Three patients experienced a recurrence of CwG, but all patients exhibited normal psychomotor development at the last follow-up. Conclusion : Afebrile infantile convulsions with gastroenteritis are brief generalized seizure in cluster with normal laboratory findings and good prognosis. Therefore CwG is likely to be categorized as situation-related seizure of special syndrome. Recognition of this entity should lead to assurance of the parents and long-term anticonvulsant therapy is not usually warranted.

Purpose : Rotavirus is the main cause of infantile diarrheal disease worldwide, especially in patients 3-24 months of age. Infants younger than 3 months of age are relatively protected by transplacental antibody. So the purpose of this study is to evaluate the clinical features and severity of neonatal rotaviral gastroenteritis less than 1 month of age. Methods : A retrospective chart review was established of 62 neonates less than 1 month of age and with a diagnosis of rotaviral gastroenteritis who had been admitted to Pochon CHA University between June 2002 through July 2004. The rotavirus was examined by stool latex agglutination. Results : During 2 years, the total number of admitted patients for rotaviral gastroenteritis was 688 and among these, less than 1 month of age accounted for 9%(62). The occurrence was generally even distribution from January to July($7.14{\pm}1.0$) but since then decreased($2.4{\pm}1.8$). The most common chief complaint was mild fever(46%) when admitted which subsided within 1 hospital day in most patients. 4 patients had seizure and cyanosis with no typical symptoms of rotaviral gastroenteritis. During admission, all the patients had diarrhea. 17% of the patients had leukocytosis and positive C-reactive protein. In one patient, stool occult blood test was positive but there was no necrotizing gastroenteritis evidence. The mean period of hospital day was $5.8{\pm}2.5$ and breast-milk feeding was 62.9%. Conclusion : Neonatal rotaviral gastroenteritis is not a rare disease. Most patients have fever and diarrhea and improve through conservative therapy but a few patients may have severe complications so we must be more cautious about the hygiene for prevention.
