We report a pediatric patient admitted with abdominal pain, diffuse lower extremity edema and watery diarrhea for two months. Laboratory findings including complete blood count, serum albumin, lipid and immunoglobulin levels were compatible with protein losing enteropathy. Colonoscopic examination revealed diffuse ulcers with smooth raised edge (like "punched out holes") in the colon and terminal ileum. Histopathological examination showed active colitis, ulcerations and inclusion bodies. Immunostaining for cytomegalovirus was positive. Despite supportive management, antiviral therapy, the clinical condition of the patient worsened and developed disseminated cytomegalovirus infection and the patient died. Protein losing enteropathy and disseminated cytomegalovirus infection a presenting of feature in steroid-naive patient with inflammatory bowel disease is very rare. Hypogammaglobulinemia associated with protein losing enteropathy in Crohn's disease may predispose the cytomegalovirus infection in previously healthy children.

We previously reported 344 cases of esophageal reconstruction for caustic esophageal stricture between 1959 and 1982, and this is the second report of 69 cases during 12 year period from Jan. 1983 to Feb. 1995. There were 32 males and 37 females, ranging in age from 4 to 65 years(mean 36.4 years). Caustic materials were acid in 37 (53.7%) and alkali in 31 (44.9%). All cases underwent colon interposition without esophageal resection except 3 cases of cancer complication which were resected through thoracotomy. In 64 cases isoperistaltic right colon with teminal ileum interposition were performed, and 5 cases were interposed with left colon either isoperistaltic (2 cases) or antiperistaltic (3 cases) method. Anastomotic leakage was the most frequently encountered c mplication (14.4%, 10 cases), and they were 11.6%(8 cases) from cervical, 2.8% (2 cases) from ileocolostoma. Overall operative mortality was 2.9% (2169), main causes of death were sepsis due to graft necrosis and mediastinitis. During 6 months to 12years (mean 2.Syears) follow-up of survived 67 cases, 88.1% (59 cases) ate normally, 7.5% (5 cases) complained of moderate dysphagia (eating liquid diet), and 4.5% (3 cases) were unable to eat by mouth. In our experience, reconstruction of the esphagus with the colon is a satisfactory method that can be accomplished with acceptable morbidity and mortality. The right colon is a durable and functional esophageal substitute.

This trial was conducted to determine the effects of feeding a diet containing solid-state fermented rapeseed meal on performance, nutrient digestibility, intestinal ecology and intestinal morphology of broiler chickens. A mixed liquid culture, containing approximately 5 log cfu/ml Lactobacillus fermentum, Enterococcus faecium, Saccharomyces cerevisae and Bacillus subtilis was prepared in a 1:1:1:1 ratio. A basal substrate (BS) containing 75% rapeseed, 24% wheat bran and 1% brown sugar was mixed with the liquid culture in a ratio of 10:3. Over the 30-day fermentation, isothiocyanates were reduced from 119.6 to 14.7 mmol/kg. A total of 168, day-old male Arbor Acres broiler chicks were assigned to one of three dietary treatments including a corn-soybean meal based control diet as well as two experimental diets in which the control diet was supplemented with 10% of the BS containing unfermented rapeseed meal or 10% of the BS containing rapeseed meal subjected to solid state fermentation. There were 8 pens per treatment and 7 birds per pen. From days 19-21 and days 40-42, uncontaminated excreta were collected from each pen for digestibility determinations. In addition, digesta from the colon and ceca were collected to determine the number of lactobacilli, enterobacteria and total aerobes. The middle sections of the duodenum, jejunum, and ileum were collected for intestinal morphology. Over the entire experimental period (d 1-42), the weight gain and feed conversion of birds fed fermented rapeseed meal were superior (p<0.05) to that of birds fed nonfermented rapeseed meal and did not differ from the soybean control. On day 42, birds fed fermented rapeseed meal had higher (p<0.05) total tract apparent digestibility coefficients for dry matter, energy, and calcium than birds fed non-fermented rapeseed meal. Colon and ceca digesta from broilers fed the fermented feed had higher (p<0.05) lactobacilli counts than birds fed the control and non-fermented rapeseed meal diets on day 21 and 42. Fermentation also improved (p<0.05) villus height and the villus height:crypt depth ratio in the ileum and jejunum on day 21 and 42. The results indicate that solid-state fermentation of rapeseed meal enhanced performance and improved the intestinal morphology of broilers and may allow greater quantities of rapeseed meal to be fed to broilers potentially reducing the cost of broiler production.

A total of 140 weaning pigs were used to determine the effects of digestive enzyme supplementation to corn-soybean meal diets on growth performance, physiological changes of small intestine, microorganisms and pH in the gastrointestinal tract. Two kinds of enzyme complex (A, B) were used in this experiment. Pigs were allotted in a completely random design (CRD) to five replicates with four pigs per pen. Diets and water were provided for ad libitum consumption. Treatments included 1) Control: without enzyme supplementation, 2) Enzyme A 0.05%, 3) Enzyme A 0.10%, 4) Enzyme A 0.15%, 5) Enzyme B 0.05%, 6) Enzyme B 0.10%, 7) Enzyme B 0.15% in the diets. A total of 24 crossbred barrows 25.78${\pm}$0.55 kg BW fitted with simple ileal T-cannulas were used to evaluate the effect the enzyme addition on the nutrient digstibility. Pigs were allotted 4 treatments (No enzyme, enzyme A 0.05%, enzyme A 0.1%, enzyme A 0.15%), 6 replicates according to a completely random design (CRD). Another digestibility trial was followed for enzyme complex B. Twenty pigs, average 31.92${\pm}$0.37 kg BW, fitted with simple ileal T-cannulas for digestibility trial. Neither enzyme A nor enzyme B affected on fecal or ileal digestibility of dry matter, gross energy, crude protein, crude fat and crude ash (p>0.05). The apparent fecal digestibilities of all the nutrients were higher in total feces collection method than in indirect method. At the end of feeding trial, 21 pigs were slaughtered for examining the morphological changes of small intestine and the concentration of microorganisms in the ileum and the colon. Growth performance, intestinal morphology and pH of ileum and colon were not affected by the either enzyme complex supplementation (p>0.05). These results suggested that enzyme complex A and enzyme complex B were of no benefit to early-weaned pigs when corn-soybean meal based diet was provided.

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder caused by mutation of one of two genes, TSC1 (encoding hamartin, 9q34) and TSC2 (encoding tuberin, 16p13). It invades the central nervous system and various parts of the body, causing various symptoms. Crohn's disease (CD) is a chronic immune-mediated disease that has not been clearly elucidated. It is thought to be caused by an excessive immune response of the body to bacteria that normally exist in the digestive tract with genetic factors. No cases have been reported in which both of the above-mentioned diseases occurred simultaneously. We report a case of CD in a patient with TSC. A 12-year-old boy was brought to our hospital because of abdominal pain. Skin lesions were observed in the TSC. Fundus examination revealed a hamartoma in the right retina. Brain magnetic resonance imaging revealed a subendothelial giant cell astrocytoma (SEGA). On the basis of these findings, he was diagnosed as having TSC. Blood test results showed increased levels of inflammatory markers. On abdominal ultrasonography, his colon walls were observed to be thickened with increased vascularity of the proximal ascending colon, ileocecal valve, and terminal ileum. Colonoscopy revealed discontinuous ulcerations and inflammations of the ileum, IC valve, and cecum, similar to those found in CD. Everolimus was administered orally for the SEGA but was discontinued frequently owing to the exacerbation of CD. The possibility of CD should be kept in mind in patients with TSC considering to undergo treatment for SEGA.

Objective: Flattening in the anteroposterior direction (AP flattening) of the terminal ileum (TI) or sigmoid colon (SC) lying across the psoas muscle, on magnetic resonance enterography (MRE), might mimic bowel inflammation in the coronal view. This study investigated the prevalence of AP flattening and the factors associated with its development. Materials and Methods: A total of 364 surgery-naïve patients with Crohn's disease (CD) who had undergone MRE were retrospectively reviewed. AP flattening was defined as a luminal collapse in the anteroposterior direction, with a bowel width in the axial plane < 1/4 of the normal diameter without reduction of bowel width in coronal images. The prevalence of AP flattening of the TI and SC on MRE in patients with bowel segments lying across the psoas muscle was determined. We further compared the rate of AP flattening between MRE and computed tomography enterography (CTE) in a subcohort of patients with prior CTE. The factors associated with AP flattening were analyzed using multivariable logistic regression in a subcohort of patients with endoscopic findings of TI. Results: Three hundred and twenty-two and 363 patients, respectively, had TI and SC lying across the psoas muscle. The prevalence of AP flattening on MRE was 7.5% (24/322) in TI and 5.2% (19/363) in SC. The prevalences were significantly higher on MRE than on CTE in both the TI (7.3% [12/164] vs. 0.6% [1/164]; p = 0.003) and SC (5.8% [11/190] vs. 1.6% [3/190]; p = 0.039). AP flattening of the TI was independently and strongly associated with the absence of CD inflammation on endoscopy, with an adjusted odds ratio of 0.066 (p = 0.003) for the presence versus the absence (reference) of inflammation. Conclusion: AP flattening of the TI or SC lying across the psoas muscle was uncommon and predominantly observed on MRE of the bowel without CD inflammation.

The study was performed to investigate the effect of dietary supplementation of a lipid-encapsulated Zinc oxide on growth parameters and intestinal mucosal morphology piglets born to Duroc-sired Landrace ${\times}$ Yorkshire dams. Twenty-four 30-day-old piglets weaned at 25 days of age were orally challenged with $5{\times}10^8$ colony forming units of enterotoxigenic Escherichia coli (ETEC) K88 and fed one of the four diets for 7 days: (i) a nursery basal diet containing 100-ppm ZnO (referred to as BASAL), (ii) BASAL supplemented with 120-ppm apramycin (referred to as ANTIBIO), (iii) BASAL with 2,400-ppm ZnO (referred to as HIGH), and BASAL containing 100-ppm lipid-encapsulated ZnO (referred to as LE). All piglets were killed at the end of the experiment for histological examination on the intestine. The results showed that the average daily gain (ADG), the villus height: crypt depth (CD) ratio in the ileum, and the goblet cell density of the villus and crypt in the duodenum, jejunum, and colon were greater in the LE-fed group that those of the BASAL (p < 0.05). Fecal consistency score (FCS) and the CD ratio in the ileum were less in the LE-fed group, compared to the BASAL-fed one (p < 0.05). The effects observed in the LE-fed group were almost equal to those of the HIGH-fed group as well as even superior to those of the ANTIBIO-fed group. Taken together, our results imply that dietary supplementation of 100-ppm lipid-encapsulated ZnO is as effective as that of 2,400-ppm ZnO for promoting growth diarrhea and intestinal morphology caused by ETEC infection.

The present study was carried out to examine the effect of insulin formula on blood glucose change in normal Sprague-Dawley male rats. Also, this study was performed to investigate the feasibility of oral insulin formula development. To administrate the insulin formula into intestine, the surgical technique, celiotomy, was performed in rats. Insulin formula was administrated at a dose of 24.5 IU/kg via duodenum, ileum, and colon of the rats, and the blood glucose level was measured. For the comparison, the vehicle without insulin was administrated into ileum via celiotomy. Also, this insulin formula was administrated into rats orally using sonde and the same parameter was treasured. The bloods of all groups were collected from tail veins using syringes at given time interval. Orally administrated group did not show the change of blood glucose level and control group slightly show the change of blood glucose level at 1 hour after celiotomy. All intestinally administrated groups showed the change of blood glucose level. Among the tested groups, ileac administration group and colonic administration group showed the significant change of blood glucose level. Particularly, ileac administration group showed the lowest blood glucose level. To calculate the bioavailability of intestinal and oral administration, insulin solution was injected subcutaneosly, common insulin injection route, into another normal rats. The bioavailability of ileac group was 8.3% when compared with subcutaneous injection, duodenal group was 1.8%, colonic group was 4.2%, and oral group was 0.2%, respectively.

The regional distributions and relative frequencies of the gastrointestinal endocrine cells in the bean goose (Anser fabalis Latham) were investigated by immunohistochemical methods using bovine Sp-1/chromogranin (CG), serotonin, gastrin, cholecystokinin (CCK)-8, somatostatin and glucagon antisera. BCG-immunoreactive cells were widespread throughout the gastrointestinal tract (GIT) with moderated frequencies except for the gizzard and proventriculus which were a few frequencies. Serotonin-immunoreactive cells were detected throughout the GIT except for the proventriculus and gizzard. These cells were observed in the pylorus with rare frequencies but numerous cells were detected in the intestinal tract. Gastrin-immunoreactive cells were restricted to the gizzard, pylorus and duodenum. These cells were most predominant in the pylorus and a few or rare in the gizzard and duodenum, respectively. CCK-8-immunoreactive cells were observed from the gizzard to ileum. The highest frequencies of endocrine cells were observed in the duodenum. These cells were increased from the gizzard to duodenum but thereafter decreased. Somatostatin-immunoreactive cells were detected in the GIT except for the large intestine. In the proventriculus and pylorus, numerous immunoreactive cells were demonstrated but a few cells were present in the other regions. Glucagon cells were observed in the gizzard, pylorus, ileum, colon and rectum with a few or moderated numbers.

In order to know the distribution, relative frequencies, types and morphology, endocrine cells in the intestinal tract of the hedgehog(Erinaceus koreanus) were studied by light microscopy, immunohistochemistry and electron microscopy. The results obtained are summarized as follows: 1. Two kinds of endocrine cells were demonstrated with two specific staining methods. Argyrophil cells(reactive cells for Grimelius method) were found most frequently in the intestinal region, and were infrequent in the rectum, whereas argentaffin cells (reactive cells for Masson-Hamperl method) were found most frequently in the rectum and in the other legions were infrequent. These reacting cells were mainly found in the intestinal glands, whereas a small number in the mucosa. 2. Twelve kinds of endocrine cells, gastrin(Gas)-, somatostatin (Som)-, serotonin(5-HT)-, glucagon(Glu)-, bovine pancreatic polypeptide(Bpp)-, cholecystokinin(Cck)-, secretin(Sec)-, motilin(Mot)-, glicentin(Gli)-, gastric inhibitor polypeptide(GIp)-, substance P(Sp)-, and neurotensin(Neu)-immunoreactive cells, were identified by immunohistochemical method. Gas-, Som-, 5-HT-, Glu-, Cck-, Sec-, Mot-, Gli-, Sp-, and Neu-reactive cells were observed in the duodenum, and among these Gas- and 5-HT-reactive cells were moderately found while the others were infrequent. In the jejunoileum Gas-, Som-, 5-HT-, Glu-, Cck-, Mot-, Gli-, GIp-, SP-, and Neu-reactive cells were found, and among these 5-HT- and GIp-reactive cells were moderately found while the others were infrequent. In the colon Sec-reactive cell was not detected. 5-HT-reactive cells were found most frequently and the others were infrequent in this region. 5-HT-, Bpp-, GIi- and Neu-reactive cells were found in the rectum. Among these 5-HT-reactive cells were found most frequently. 3. Electron microscopically, five types of endocrine cells, EC, ECL, D, G, A-like cell, were identified in the intestinal region. EC and ECL cells in the duodenum, EC, D and G cells in the jejuno-ileum, EC and A-like cells in the colon and EC cell in the rectum were observed respectively.
