Objectives : Ulcerative colitis and Crohn's diseases are chronic inflammatory disease of the gastrointestinal tract identified mainly for diarrhea, stomachache, hemafecia. The source and pathologic mechanism about ulcerative colitis and Crohn's disease are still unknown but stress, infection, a genetic factor, environmental factors etc. may be the cause of chronic inflammatory disease of the gastrointestinal tract recently. Methods : Because ulcerative colitis and Crohn's disease is recognized as Ha-ri(下痢) or Jang-Byok(腸?) in Oriental Medicine, Rhizoma Coptidis Herbal acupunctures were injected in hapgok $(LI_4)$ which is used to treat intestinal disease in clinic. All animals were subjected to the injection of saline $(300\;{\mu}l,\;500\;{\mu}l)$ for a study control and TNBS $(300\;{\mu}l,\;500\;{\mu}l)$ into the lumen of the colon, 8cm proximal to the anus through the intestine. Rhizoma Coptidis Herbal (20 mg/ml, 0.4 ml) acupuncture solution was injected to the $LI_4$ (both hands) at the secondary injection time of TNBS in rats. And body weight, RBC count, WBC count, total protein, Paw edema rate, rate of protein leakage into CMC-pouch fluid, IgG levels and IgM levels were observed to study the effects of Rhizoma Coptidis Herbal acupuncture in hapgok $(LI_4)$. Results : In results, Rhizoma Coptidis Herbal acupuncture in hapgok $(LI_4)$ on TNBS-induced colitis reduced the rate of weight loss but had no effect on RBC and WBC count. And it reduced total protein concentration, paw edema, rate of protein leakage into CMC-pouch fluid, IgG levels and IgM levels. Conclusion : Data suggest that injection of Rhizoma Coptidis herbal acupuncture solution into hapgok has significant therapeutic effect on the colitis.

Malrotation is a congenital anomaly that becomes symptomatic more frequently during infancy. The indication for surgical treatment at that age is straightforward. In older children, the diagnosis may be more difficult because of chronic and vague complaint. The aim of this study is to compare the symptoms, rate of volvulus and surgical findings in children younger and older than one year. A retrospective study of 40 patients in a a single medical center diagnosed with malrotation from April 1996 to May 2010 was performed. There were 20 (50 %) boys and 20 (50 %) girls. At the time of operation, 27 (67.5 %) patients were younger and 13 (32.5 %) were older than 1 year. Vomiting was seen in 20 cases (74.1 %) of the younger group compared to 2 cases (15.4 %) of the older group. Abdominal sonography and upper gastrointestinal series showed a sensitivity of 100%. Operative findings: 12 (44.4 %) of the younger group presented with volvulus compared to none of the older group. The Ladd's procedure was routinely performed with appendectomy in all cases and bowel resection was requires when volvulus included bowel necrosis or other anomalies were found. After definite procedures, surgical correction for adhesive obstruction was necessary in 5 menbers (18.5 %) of the younger group and 1 patient (7.7 %) in the older group. There was 1 death due to respiratory failure and pneumonia. Abdominal pain was more frequent symptom and bilious vomiting was less frequent. Volvulus did not occur in the older group. Malrotation should be diagnosed promptly in children over 1 year of age by upper gastrointestinal series and abdominal ultrasonography even though symptoms are not as clear cut as in infants.

The principal objective of this study was to compare the effects of whole and hydrolyzed cells (bifidobacteria) treated with gastrointestinal digestive enzymes on the activation of cloned macrophages. Seven different strains of Bifidobacterium obtained from swine, chickens, and rats, were digested with pepsin followed by pancreatin and the precipitate (insoluble fraction) and supernatant (soluble fraction) obtained via centrifugation. The RAW 264.7 murine macrophages were incubated with either whole cells, the precipitate, or supernatant at various concentrations. Pronounced increases in the levels of nitric oxide (NO), interleukin $(IL)-1{\beta}$, IL-6, IL-12, and tumor necrosis factor $(TNF)-{\alpha}$ were observed in the whole cells and precipitates, but these effects were less profound in the supernatants. The precipitates also evidenced a slight, but significant, inductive activity for NO and all tested cytokines, with the exception of $(TNF)-{\alpha}$ in the macrophage model as compared with the whole cells. By way of contrast, $(TNF)-{\alpha}$ production when cultured with whole cells (100 ng/ml) resulted in marked increases as compared with what was observed with the precipitates. The results of this study indicated, for the first time, that digested Bifidobacterium sp. can induce the production of NO and several cytokines in RAW 264.7 murine macrophage cells. In the current study, it was demonstrated that Bifidobacterium strains treated with digestive enzymes, as compared with whole cells, are capable of stimulating the induction of macrophage mediators, which reflects that they may be able to modulate the gastrointestinal immune functions of the host.

Cimetropium bromide, a quaternary ammonium compound which is chemically related to scopolamine, exhibits its antispasmodic activity by competing with acetylcholine for the muscarinic receptors of the smooth muscle of gastrointestinal tract. The drug has been used for the treatment of various disorders involving spasms of the musculature of the gastrointestinal, biliary and genitourinary tracts. The purpose of the present study was to evaluate the bioequivalence of two cimetropium bromide tablets, $Algiron^{TM}$ (Boehringer Ingelheim Korea Ltd.) and $Alpit^{TM}$ (Hana Pharmaceutical Co., Ltd.), according to the prior and revised guidelines of Korea Food and Drug Administration (KFDA). The cimetropium bromide release from the two cimetropium bromide tablets in vitro was tested using KP VII Apparatus II method with various different kinds of dissolution media (pH 1.2, 4.0, 6.8 buffer solution and water). Twenty normal male volunteers, $25.25{\pm}2.10$ years in age and $65.76{\pm}6.39$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After three tablets containing 50 mg of cimetropium bromide per tablet were orally administered, blood was taken at predetermined time intervals and the concentrations of cimetropium bromide in serum were determined using HPLC method with UV detector. The dissolution profiles of two cimetropium bromide tablets were very similar at all dissolution media. Besides, the pharmacokinetic parameters such as $AUC_t,\;C_{max}\;and\;T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters using non-transformed and logarithmically transformed $AUC_t\;and\;C_{max}$. The results showed that the differences in $AUC_t,\;C_{max}\;and\;T_{max}$ between two tablets based on the $Algiron^{TM}$ were 2.19%, -5.97% and 3.49%, respectively. Minimum detectable differences $({\Delta})\;at \;{\alpha}=0.05\;and\;1-{\beta}=0.8$ were less than 20% (e.g., 13.71 %, 19.05% and 15.11% for $AUC_t,\;C_{max}\;and\;T_{max}$, respectively). The powers $(1-{\beta})\;at\;{\alpha}=0.05,\;{\Delta}=0.2\;for\;AUC_t$, $C_{max}\;and\;T_{max}$ were 97.79%, 83.22% and 95.60%, respectively. The 90% confidence intervals were within ${\pm}20%$ (e.g., $-5.84{\sim}10.21,\;-17.11{\sim}5.18\;and\;-5.35{\sim}12.33\;for\;AUC_t,\;C_{max}\;and\;T_{max}$, respectively). There were no sequence effect between two tablets in logarithmically transformed $AUC_t\;and\;C_{max}$. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log(1.25) (e.g., $0.94{\sim}1.10\;and\;0.85{\sim}1.05\;for\;AUC_t\;and\;C_{max}$, respectively). Two parameters met the criteria of prior and revised KFDA guideline for bioequivalence, indicating that $Alpit^{TM}$ tablet is bioequivalent to $Algiron^{TM}$ tablet.

Purpose: The aim of this study was to compare the efficacy and safety of band ligation and injection sclerotherapy in the endoscopic treatment of children with variceal bleeding. Methods: The study population included 55 children, all of whom were treated at the time of endoscopic diagnosis of esophageal varices at Asan Medical Center, Seoul, Korea, between January 1994 and January 2011. The primary outcomes included initial success rates and duration of hemostasis after endoscopic management (band ligation vs. injectionsclerotherapy). Results: The mean age was $6.7{\pm}5.2$ years and the mean follow-up time was $5.4{\pm}3.7$ years. The most common cause of esophageal varices was biliary atresia. Of 55 children with acute variceal bleeding, 39 had band ligation and 16 had injection sclerotherapy. No differences between groups were observed in terms of the size, location, and presence of red color sign. The success rates of band ligation and sclerotherapy in the control of acute bleeding episodes were 89.7% and 87.5%. The mean duration of hemostasis after endoscopic intervention was $13.2{\pm}25.1$ months. After one year, 19 of 39 patients (48.7%) treated with band ligation and 7 of 16 patients (43.8%) with injection sclerotherapy had experienced rebleeding episodes. Complications after the procedures were observed in 10.3% and 18.8% of children treated with band ligation and injection sclerotherapy. Conclusion: The results of our current study suggest that band ligation and injection sclerotherapy are equally efficient treatments for the control of acute variceal bleeding and prevention of rebleeding.

Purpose: Febrile urinary tract infection (UTI) is one of the commonest bacterial infections in children. The purpose of this study is to investigate the clinical characteristics of the first episode of febrile UTI occurring in children over 5 years compared to those in infants younger than a year. Methods: We retrospectively reviewed the medical records of 10 patients over 5 years, having febrile UTI, and 25 controls under 1 year. Clinical characteristics including symptoms at admission, the time interval between symptom onset and hospital visit and/or diagnosis, duration of fever, urinalysis, and other laboratory and imaging test results were compared between the two groups. Results: Most patients in the control group showed only high fever at the time of presentation to the hospital. However, 60% of the case group had fever along with gastrointestinal (GI) symptoms such as abdominal and flank pain, vomiting, as well as relatively mild pyuria. The case group showed a longer duration between symptom onset and hospital visit and/or diagnosis. Conclusions: Delay in diagnosis and initiation of treatment of UTI increases the risk of permanent renal scarring and associated complications. Therefore, early diagnosis and treatment of febrile UTI is vital for very young infants, as well as children considering that febrile UTI could be an important cause of febrile illness in children over 5 years.

4-tert-octylphenol (OP) is a surfactant additive widely used in the manufacture of a variety of detergents and plastic products. Also, OP is known to have estrogenic activity by interacting with development and functions of endocrine system. This study was carried out to obtain toxicokinetic parameters of OP in male Sprague-Dawley rats. Male rats were administered OP, by either single oral (gavage) applications of 50, 100 or 200 mg/kg body weight. or a single intravenous injections of 1, 5 or 10 mg/kg body weight. Blood samples taken at several time intervals after administration were obtained from the femoral artery. Analysis of blood samples for OP was performed by gas chromatography mass spectrometry (GC/MS). The detection limit of OP was 1.9 ng/$m\ell$ at SIM (selected ion monitoring) mode of GC/MS. Calibration curve for analysis of the concentrations of OP in plasma was (OP/butylphenol peak area ratio) = 0.0294 $\times$ (plasma cone.) + 0.028 ($r^2$= 0.9991). The OP plasma concentration was 3921 ng/$m\ell$ immediately after single intravenous application, decreased rapidly within 45 min, and was detectable at low concentration up to 6 hr after application. When administered orally in rats (50, 100 and 200 mg/kg), OP was detected in the blood early after gavage administration, indicating the rapid initial uptake from gastrointestinal tract, with Tmax obtained from 0.67~0.83 hr. Using the AUC (area under the curve) of plasma concentration vs. time, low oral bioavailabilities of 1.2, 5.0 and 5.3% were calculated for the 50, 100 and 200 mg/kg groups, respectively.
