Objectives : This study was carried out to investigate the effects of Sasammaickmoondong-tang(SME) on duodenal mucosal lesions induced by indomethacin in mouse. Methods : The normal group is that no inflammation elicitated mouse. Control group is that gastro-inflammation elicitated mouse. Sample group is that SME administered mouseice after gastro-inflammation elicitation. Results : In the common morphology and histochemical change, control group was observed various injury-mucous surface cell, micro-villi, paneth cell, surface epithelial cell, goblet cell-by hemorrhagic erosion, while sample group was as same as normal group. In the immunohistochemical change, the distributions of COX-1, Bcl-2, and BrdU treated with SME noticeably increased than control group(p<0.05). The distributions of TUNEL, $NF-{\kappa}B$, COX-2, $IL-2R-{\alpha}$, NK-1.1, ICAM-1, and CD11b/18 treated with SME noticeably decreased than control group(p<0.05). And the distribution of SBA was as same as normal group. Conclusion : According to the above results, it is supposed that Sasammaickmoondong-tang is applicable to duodenal mucosal lesions.

The in vitro permeation of thyrotropin-releasing hormone (TRH) through rabbit nasal, rectal and duodenal mucosae was studied in the absence and presence of an enzyme inhibitor and permeation enhancer. TRH in the donor and receptor solutions was assayed by HPLC. When thimerosal (TM, 0.5 mM) was added to the donor cell as an inhibitor, the permeation rate of TRH (200 $\mu\textrm{g}$/ml) increased linearly as a function of time. Fluxes of TRH through the nasal, rectal and duodenal mucosae were found to be 33.3$\pm$5.9, 11.8$\pm$1.9 and 9.6$\pm$0.7 $\mu\textrm{g}$/$\textrm{Cm}^2$/hr, respectively. The addition of sodium glycocholate, glycyrrhizic acid ammonium salt, sodium taurodihydrofusidate or L-$\alpha$-lysophosphatidylcholine to the donor solution containing TM did not result in the significant increase of permeation flux except for the duodenal mucosa, comparing with that in the presence of TM alone. Consequently, it was suggested that the nasal route was advantageous for systemic delivery of TRH, and the addition of TM and/or an enhancer was necessary to maximize the transmucosal permeation of TRH.

Ganglioneuroma of the gastrointestinal tract is a rare tumor that consists of ganglion cells, nerve fibers, and supporting cells of the enteric nervous system. Ganglioneuromas are usually associated with genetic disorders such as the multiple endocrine neoplasia syndrome or neurofibromatosis. Ganglioneuromas of the gastrointestinal tract predominantly involve the colon and rectum, and reports about duodenal ganglioneuromas are few. Herein, we report a case of duodenal ganglioneuroma treated with endoscopic resection. A 56-year-old female patient visited our hospital because of a subepithelial tumor in the second portion of the duodenum. She had no remarkable medical or family history and revealed no history of genetic disorders. Endoscopic ultrasonography and abdominal computed tomography revealed a tumor located mainly in the submucosal layer, without any regional lymph node involvement. Endoscopic resection of the lesion was performed, and the pathological examination confirmed a duodenal ganglioneuroma.

Cdc25B is a mitotic regulator that might act as a starter phosphatase to initiate the positive feedback loop at the entry into mitotic (M) phase. In the present study, distribution of Cdc25B mRNA in duodenal mucosa of the chicken was demonstrated by means of in situ hybridization histochemistry (ISHH) using sense and antisense digoxigenin (DIG)-labeled RNA probes. The results showed that there were many labeled cells distributing in the duodenal mucosa of the adult chicken. Of these labeled cells, 81.60${\pm}$9.63% of Cdc25B mRNA positive cells was distributed in the basilar part and mid-portion of the intestinal gland and 36.21${\pm}$8.81% in the middle and basilar portion of villi of the small intestine of the chicken, respectively. Most of these labeled cells were positive in the regions of the stem cell and proliferation. The signals of ISHH decreased from basilar to upper part in the crypt of Lieberkuhn and weakened in the inferior villi of the duodenum. Moreover, the positive signals were both in the cytoplasm and cell nucleus. However, the labeled cells were negative in both the lamina muscularis mucosae and muscular layer. The results of ISHH suggested the existence of Cdc25B mRNA and vigorous proliferation activities in the duodenal mucosa of adult chicken, replenishing the cells which had sloughed off from the superior part of the villus. Our results provide some molecular evidence for a regular pattern of avian intestinal epitheliosis and functional partition and provide an approach to further study of the locations of Cdc25B in the chicken.

Seventy neonates with congenital intestinal atresia and stenosis who were treated at pediatric surgical service. Hanyang University Hospital from September 1979 to December 1996 were analyzed retrospectively. The lesion occurred in 27 cases at the duodenum, in 26 cases at the jeiunum, in 13 cases at the ileum and in 2 cases at the pylorus and colon each. There were 10 multiple atresias and 7 apple-peel anomaly cases. The atresia predominated over the stenosis by the ratio of 4 : 1. Male to female ratio was 1.3 : 1. The average gestational age was 38 weeks, and the average birth weight was 2,754 grams. Though 22.9 % were borne prematurely and 34.3 % had low birth weight, 92.3 % of them had a weight appropriate for gestational age. Polyhydramnios(40 %) was more frequently observed in duodenal and jeiunal atresia while microcolon in ileal atresia(58.3 %). Weight loss and electrolyte imbalance occurred more frequently in the duodenal stenosis cases because of delayed diagnosis. Twenty(55.6 %) of 37 jeiunoileal atresia cases had evidence of intrauterine vascular accident : 4 intrauterine intussusception, 3 intrauterine volvulus and 3 strangulated intestine in gastroschisis, and 10 cases of intrauterine peritonitis. There were one or more associated anomalies in 45 patients (64.3 %). Preoperatively proximal loop volvulus developed in 3 cases and proximal loop perforation in 5 cases and one case each of distal loop perforation, duodenal perforation and midgut volvulus occurred in the jeiunoileal atresia. Overall mortality rate was 20 %.

Purpose: Duodenal stump leakage (DSL) is a potentially fatal complication that can occur after gastrectomy, but its underlying risk factors are unclear. This study aimed to investigate the risk factors and management of DSL after laparoscopic radical gastrectomy for gastric cancer (GC). Materials and Methods: Relevant data were collected from several prospective databases to retrospectively analyze the data of GC patients who underwent Billroth II (B-II) or Rouxen-Y (R-Y) reconstruction after laparoscopic gastrectomy from 2 institutions (Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, and HwaMei Hospital, University of Chinese Academy of Sciences). The DSL risk factors were analyzed using univariate and multivariate analysis regression. Results: A total of 810 patients were eligible for our analysis (426 with R-Y, 384 with B-II with Braun). Eleven patients had DSL (1.36%). Body mass index (BMI), elevated preoperative C-reactive protein (CRP) level, and unreinforced duodenal stump were the independent risk factors for DSL. DSL was diagnosed in 2-12 days, with a median of 8 days. Seven patients received conservative treatment, 3 patients received puncture treatment, and only 1 patient required reoperation. All patients recovered successfully after treatment. Conclusions: The risk factors of DSL were BMI ≥24 kg/㎡, elevated preoperative CRP level, and unreinforced duodenal stump. Nonsurgical treatments for DSL are preferred.

To identify, the effects of acua-acupuncture of Bletillae rhizoma extract on the duodenal ulcer induced by HCl-aspirin in rats, the changes of histological profiles, number of mucous-producing goblet cells (PAS-positive cells), and morphology and/or number of chole-cystokinin (CCK)-8 and serotonin-immunoreactive (IR) cells in the gastrointestinal tract were observed after acua-acupuncture of Bletillae rhizoma extract on Ganshu locus ($BL_{14}$). Samples were collected at 1, 3 and 5 days after treatment. Histologically, very severe injury, atrophy of villus, necrosis of epithelial cell and hemorrhage, to the duodenal mucosa including epithelium were observed in HCl-aspirin administrated control groups, and these injuries were increased with time intervals. But in acua-acupuncture groups and nontreated normal groups, no gross lesion of ulcer was demonstrated and histologically minor injury to the apex of villas epithelium was observed. Compared to the PAS-positive cells of the control groups, those of the acua-acupuncture groups were increased. Severe degranulation of CCK-8- and serotonin-IR cells were observed in the control groups but these phenomena seldom occur in the acua-acupuncture groups. Serotonin-IR cells were significantly decreased in control groups but increased in the acua-acupuncture groups compared to control groups. However, these degranulation of IR cells of the aqua-acupuncture groups were less severe than those of normal groups, and number of serotonin-IR cells were lower than those of normal groups but these phenomena were decreased with time intervals and in 5 days after treatment, they were observed like those of normal groups. These result indicated that acua-acupuncture of Bletillae rhizoma extract would be accelerated the healing of the duodenal ulcer but the functional mechanisms were unknown.

Purpose: This study aimed to evaluate a possible association between the anti-tissue transglutaminase antibody (anti-tTG) titer and stage of duodenal mucosal damage and assess a possible cut-off value of anti-tTG at which celiac disease (CD) may be diagnosed in children in conjunction with clinical judgment. Methods: This observational study was conducted at a gastroenterology clinic in a tertiary hospital from April 2012 to May 2013. Seventy children between 6-months and 18-years-old with suspected CD underwent celiac serology and duodenal biopsy. Statistical analyses were done using SPSS 16. Diagnostic test values were determined for comparing the anti-tTG titer with duodenal biopsy. An analysis of variance and Tukey-Kramer tests were performed for comparing the means between groups. A receiver operating characteristics curve was plotted to determine various cut-off values of anti-tTG. Results: The mean antibody titer increased with severity of Marsh staging (p<0.001). An immunoglobulin (Ig) A-tTG value at 115 AU/mL had 76% sensitivity and 100% specificity with a 100% positive predictive value (PPV) and 17% negative predictive value (NPV) for diagnosis of CD (p<0.001, 95% confidence interval [CI], 0.75-1). Conclusion: There is an association between the anti-tTG titer and stage of duodenal mucosal injury in children with CD. An anti-tTG value of 115 AU/mL (6.4 times the upper normal limit) had 76% sensitivity, 100% specificity, with a 100% PPV, and 17% NPV for diagnosing CD (95% CI, 0.75-1). This cut-off may be used in combination with clinical judgment to diagnose CD.

목적: H. pylori에 대해서는 최근 많은 연구가 진행되어 성인과 소아에서 위염과 강한 관련성이 있으며 위 점막은 물론 십이지장 점막에서 위 상피화생이 발생하면 미란과 궤양이 발생할 수 있는 것으로 보고되어 왔다. 그러나 소아에서의 H. pylori 감염과 관련된 십이지장의 조직병리학적 소견에 대한 연구는 아직까지 미미한 실정이므로 본 연구에서는 H. pylori에 감염된 소아에서 십이지장염, 십이지장 궤양 및 위 상피화생에 대한 관계를 규명해보고자 하였다. 방법: 2001년 10월부터 2004년 4월까지 가천의대 길병원 소아과에 내원하여 위 전정부와 위 체부 및 십이지장 점막에서 생검을 동시에 시행한 177명의 환아를 대상으로 H. pylori 감염 여부 및 병리학적 소견을 전향적 방법으로 조사 분석하였다. H. pylori 양성은 조직의 Giemsa stain에서 H. pylori가 발견되었을 때와 H. pylori IgG, urease breath test (UBT), rapid urease test (CLO) 중 2가지 이상에서 양성일 때로 정의하였다. 십이지장염은 hematoxylin 및 eosin 염색에서 간질의 세포 침윤 정도에 따라 제 0도에서 제 3도까지로 분류하였으며, 위 상피화생은 제 0도에서 제 4도까지로 구별하였다. 통계적 분석은 컴퓨터 프로그램 SAS (version 8.1)를 이용하였다. 결과: 1) 대상 환아 177명 중 H. pylori 양성 반응을 보인 환아는 97명(54%)으로 남녀 비는 1.36 : 1이었으며, 평균 나이는 9.66세였다. 2) 십이지장염은 163명에서 확인되었는데 94명에서 제 1도 소견을 보였고 이 중 H. pylori 감염은 47명이었다. 제 2도는 62명으로 이 중 H. pylori 감염은 36명이었으며, 제 3도는 7명으로 이 중 H. pylori 감염은 4명이었다. H. pylori 감염과 십이지장염 간에는 유의한 상관관계가 없었다. 3) 십이지장 궤양은 11명으로 평균 나이는 7.18세였으며 남녀 비는 4.5 : 1이었다. 이 중 H. pylori 감염 양성은 4명, H. pylori 감염 음성은 7명이었으나 통계적으로 유의한 차이점을 보이지 않았다. 4) 위 상피화생은 전체 환자 중 5명으로 이 중 H. pylori 양성은 2명이었으며 십이지장 궤양은 3명이었는데, 십이지장 궤양과 H. pylori 양성이 동반된 경우는 1명이었다. H. pylori 감염과 위 상피화생 발생간에는 통계적으로 유의한 상관관계를 보이지 않았다. 그러나 십이지장 궤양이 있는 군에서 위 상피화생의 발생률이 더 높았다(p=0.032). 5) 십이지장 궤양은 십이지장염 제 1도 94명 중 1명, 제 2도 62명 중 5명, 제 3도 7명 중 5명에서 각각 발생하여 십이장염의 정도가 증가할수록 십이지장 궤양의 발생이 증가하였다(p<0.0001). 6) 위 상피화생은 십이지장염 제 1도 94명 중 2명, 제 2도 62명 중 1명, 제 3도 7명 중 2명에서 각각 발생하여 십이지장염이 심할수록 위 상피화생의 발생이 증가하였다(p=0.0365). 결론: 기존의 문헌들에서와 달리 본 연구에서는 H. pylori 감염과 십이지장염, H. pylori 감염과 십이지장 궤양 및 H. pylori 감염과 위 상피화생 간에는 연관성이 없었으며, 십이지장염과 십이지장 궤양 간에는 연관성이 있었다. 그러나 위 상피화생과 십이지장 궤양 및 십이지장염과 위 상피화생 간에는 기존의 보고들처럼 연관성이 있음을 알 수 있었다.
