A vitelline duct (VD) anomaly is a relatively common congenital abnormality of the umbilical area. The anomalies include patent vitelline duct (PVD), cyst, fistula or sinus. The incidence is approximately 2% of the populations, but development of symptoms is rare. Recently, we experienced two cases; PVD accompanied by a small omphalocele and intestinal volvulus due to mesenteric band between Meckel's diverticulum and the mesentery. Thereafter,we evaluated the data of vitelline duct anomalies for 27 years. From 1980 to 2006, 18 cases of VD anomalies were reviewed based on the hospital records retrospectively. There were 15 boys and 3 girls and age ranged from 2 days to 15 years. Among the 18 cases, 15 cases were symptomatic and consisted of Meckel's diverticulum (10 cases), PVD (4 cases) and umbilical polyp (1 case). Three asymptomatic cases of Meckel's diverticulum were found incidentally were and were observed without resection. Ten cases of Meckel's diverticulum were presented with intestinal bleedings (4 cases), intestinal obstructions (5 cases) and perforation (1 case). Wedge resections and segmental resections of ileum were performed in 8 patients and 2 patients, respectively. Postoperative complications were adhesive ileus (1 case) and wound seroma (1 case). Small omphaloceles were accompanied in two of 4 PVD patients. There was 1 small omphalocele case which was accompanied by a prolapse of ileum. In summary, VD anomalies were more common in male and more than half of them were found in patients less than 1 year of age. PVD was diagnosed most frequently in neonates. Meckel's diverticulum presented with intestinal obstruction more frequently than bleeding.

Eight crossbred barrows (four growing and four finishing pigs with average initial BW of 40 and 82 kg, respectively) were fitted with T-cannulas at the distal ileum and used in a 36 d metabolism experiment ($4{\times}4$ Latin squares) to determine the effects of roasting and extruding full-fat soybeans on nutrient utilization. Treatments were: 1) soybean meal; 2) roasted soybeans; 3) extruded soybeans; and 4) soybeans extruded with an extrusion enhancer (sodium sulfite). The control diet was corn starch-based with 0.90% lysine, 0.65% Ca and 0.55% P for the growing pigs and 0.75% lysine, 0.55% Ca and 0.45% P for the finishing pigs. For the growing pigs, apparent total tract digestibilities of DM (p<0.04) and GE (p<0.008) were greater for soybean meal than full-fat soy products. However, ileal digestibilities of DM, GE, N and most amino acids were, in general, greatest for extruded soybeans and lowest for roasted soybeans, with soybean meal intermediate. For finishing pigs, trends in digestibilities of nutrients were very similar to those for the growing pigs. Total tract digestibilities of DM (p<0.03) and GE (p<0.001) for soybean meal were greater than for the full-fat soy products and ileal digestibilities of DM, GE, N and most amino acids were greater for the extruded soybeans than for the roasted soybeans. In conclusion, nutrient digestibilities and availabilities of indispensable amino acids tended to be greatest in extruded soybeans, intermediate in soybean meal and lowest in roasted soybeans for growing and finishing pigs.

In order to investigate the pharmacological activities of the combined preparation of crude drugs, Chunghyulgangki-Tang was studied. Chunghyulgangki-Tang has been widely used to cerebral apoploxy, hypertension and arteriosclerosis, etc. In this study, water extract of Chunghyulgangki-Tang was conducted in attempt to investigate for analgesic, sedative, antipyretic, isolated ileum and heart, blood vessels and blood pressure action in mice, frogs, rats, guinea-pigs and rabbits. The following results were obtained; Analgesic action by the acetic acid stimulating method in mice was recognized. Sedative activities by the wheel cage method and rotor rod method in mice were shown. Prolonged action against the hypnotic duration induced by thiopental-Na was significantly noted in mice. The effect of antipyretic in endotoxin febrile rats was significantly recognized. Spontaneous motility of the isolated ilem of mice was suppressed and contractions of the isolated ileum of mice and guinea-pigs induced by acetylcholine chloride, barium chloride and histamine were remarkably inhibited. Acceleration of isolated heart motility was shown in frogs. Vaso-dilating and hypotensive actions were recognized in rabbits. According to the above results, effects based on the oriental medicinal references were approximate to the actural experimental results.

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.

A 72-year-old man with progressive, unexplained lower gastrointestinal bleeding presented to the emergency department with abdominal pain and shock. Computed tomography of the abdomen showed a fistula between a right common iliac artery aneurysm and the small intestine. Laparotomy demonstrated a saccular aneurysm of the common iliac artery with a fistulous communication to the terminal ileum. Aneurysmectomy, aortoiliac graft replacement and segmental ileocecal resection with end-to-side anastomosis were all successfully performed. For a patient having an arterioenteric fistula along with lower gastrointestinal bleeding, making an early diagnosis using computed tomography and then performing immediate surgery can be expected to save the patient's life.

Objective: This study assessed the effects of probiotics on cecal microbiota, gene expression of intestinal tight junction proteins, and immune response in the cecal tonsil of broiler chickens challenged with Salmonella enterica subsp. enterica. Methods: One-day-old broiler chickens (n = 240) were randomly allocated to four treatments: negative control (Cont), multi-strain probiotic-treated group (Pro), Salmonella-infected group (Sal), and multi-strain probiotic-treated and Salmonella-infected group (ProSal). All chickens except those in the Cont and Pro groups were gavaged with 1×10⁸ cfu/mL of S. enterica subsp. enterica 4 days after hatching. Results: Our results indicated that body weight, weight gain, and feed conversion ratio of birds were significantly reduced (p<0.05) by Salmonella challenge. Chickens challenged with Salmonella decreased cecal microbial diversity. Chickens in the Sal group exhibited abundant Proteobacteria than those in the Cont, Pro, and ProSal groups. Salmonella infection downregulated gene expression of Occludin, zonula occludens-1 (ZO1), and Mucin 2 in the jejunum and Occludin and Claudin in the ileum. Moreover, the Sal group increased gene expression of interferon-γ (IFN-γ), interleukin-6 (IL-6), IL-1β, and lipopolysaccharide-induced tumor necrosis factor-alpha factor (LITAF) and reduced levels of transforming growth factor-β4 and IL-10 compared with the other groups (p<0.05). However, chickens receiving probiotic diets increased Lactobacillaceae abundance and reduced Enterobacteriaceae abundance in the ceca. Moreover, supplementation with probiotics increased the mRNA expression of Occludin, ZO1, and Mucin 2 in the ileum (p<0.05). In addition, probiotic supplementation downregulated the mRNA levels of IFN-γ (p<0.05) and LITAF (p = 0.075) and upregulated IL-10 (p = 0.084) expression in the cecal tonsil. Conclusion: The administration of multi-strain probiotics modulated intestinal microbiota, gene expression of tight junction proteins, and immunomodulatory activity in broiler chickens.

The present study was conducted to determine the effects of chitosan on nitric oxide (NO) content and inducible nitric oxide synthase (iNOS) activity in serum, and relative expression of iNOS mRNA in the duodenum, jejunum, and ileum of broiler chickens. A total of 240 one-day-old Arbor Acre mixed-sex broiler chickens were randomly allotted to six dietary treatments with five replicates in each treatment and eight chickens in each replicate. The broiler chickens in the six treatments were fed the basal diet supplemented with 0 (control), 0.05, 0.2, 0.5, 1.0 or 2.0 g/kg chitosan. The trial lasted for 42 days. The results showed that dietary chitosan enhanced NO content and iNOS activity in serum as well as iNOS mRNA expression in the duodenum and ileum of broiler chickens in a quadratic dose-dependent manner (p<0.05), and improved jejunum iNOS mRNA expression in a quadratic dose-dependent manner (p<0.10) with increasing addition of chitosan. Chicks fed a diet containing 0.5-1.0 g/kg chitosan had higher NO content and iNOS activity in serum as well as small-intestinal iNOS mRNA expression compared with birds given the control diet, but positive effects of chitosan tended to be suppressed when addition of chitosan in the diet was increased to 2.0 g/kg. These results implied that there was a threshold level of chitosan inclusion beyond which progressive reductions in serum NO content and small intestinal iNOS expression occured, and the regulation of chitosan on immune functions in chickens is probably associated with activated expression of iNOS and NO secretion.

The aim of this study was to clarify the mechanism of the inhibitory action of carbon monoxide (CO) on contraction, by measuring cytosolic $Ca^{2+}$ level $([Ca^{2+}]_i)$ and ionic currents in guinea-pig ileum. CO (10%) inhibited 40 mM KCl-induced contraction and this effect was blocked by ODQ $(1\;{\mu}M),$ a soluble guanylyl cyclase (sGC) inhibitor. CO inhibited the 40 mM KCl-induced contraction without changing $[Ca^{2+}]_i.$ Cumulative addition of KCl induced a graded increase in $[Ca^{2+}]_i$ and muscle tension. In the presence of CO, cumulative addition of KCl induced smaller contraction than in the absence of CO. On the other hand, the increase in $[Ca^{2+}]_i$ induced by cumulative addition of KCl was only slightly decreased in the presence of CO, and the $[Ca^{2+}]_i-tension$ relationship shifted downwards. Using the patch clamp technique with a holding potential of -60 mV, we found that CO had little effect on the peak Ba currents $(I_{Ba})$ when voltage was stepped from -60 mV to 0 mV. In addition, CO showed no effect on the depolarization-activated outward $K^+$ currents in the all potential ranges. We conclude that CO inhibits smooth muscle contraction mainly by decreasing the $Ca^{2+}$ sensitivity of contractile elements via a cGMP-dependent pathway, not by involving L-type $Ca^{2+}$ and outward-potassium currents in guinea-pig ileum.

The objective of these experiments gas to investigate the feeding of Powerfeel supplementation on performance and intestinal microflora of broiler chicks. Five treatments were allocated into 0, 0.025, 0.050, 0.075, 0.10% Powerfeel with four replications for five weeks. Diets contained 21.5% CP, 3,100 kcal/kg ME for the first three weeks and 19% CP, 3,100 kcal/kg ME for the rest two weeks. Weight gain, feed intake, feed conversion were weekly measured. E. coli and Salmonella were examined from cecum and ileum at the end of experiment. ND titer were also measured at five weeks old after first and booster vaccination at 14 and 21 days of age. In experiment 1, Weight gain of Powerfeef treatments was significantly higher for five weeks (P〈0.05). Feed intake increased on all Powerfeel treatments. Chicks fed Powerfeel improved feed conversion ratio(FCR) significantly compared to that of control (P〈0.05), but was not shown the consistency. In experiment 2, Weight gain and feed consumption of chicks fed Powerfeel were tended to increase, but were not statistically different from control. Powerfeel treatments showed significantly lower FCR than control(P〈0.05). The number of Salmonella and E. coli of chicks ileum fed Powerfeel were highly decreased, compared to those of control in both experiments. Powerfeel supplementation seemed to decrease the number of both Salmonella and E. coli in illeum, but was not consistency in cecum. Chicks fed Powerfeel showed significantly higher ND titer than control (P〈0.05). These results indicated that the optimum level of Powerfeel to maximize the performance of broiler chicks were estimated from 0.050 to 0.075% in broiler diets.

The experiment was conducted to determine the effects of dietary supplementation of enzyme(Endopower) into corn-soybean meal diet on the performance of broiler chicks. Three hundred sixty 3 day-old male broiler chicks(Ross) were divided into 4 groups with 3 replicates of 30 birds per replicate and assigned at random to each of four treatment groups for two energy levels(3100 and 2980 kcal TMEn/kg) with 0 or 0.1% Endopower in the diet. The body weight gain of birds fed the low energy diet with 0% Endopower was lower significantly than the other groups(P<0.05). There were no significant differences in feed intake and feed conversion rate among the treatments. The relative sizes(% B. wt) of the liver and leg muscle were not different significantly among the treatments. The breast muscle weights of the low energy diet birds were higher than those of the high ones, and those of the lower energy group with 0.1% Endopower were highest. The intesinal lengths(cm/B.wt) of low energy diet group without Endopower were lower than those of the others. No significant differences in the relative jejunum and ileum weights were found, but % duodenum weights of high energy group were higher than those of the low energy group. The villi of the ileum of birds fed corn-soybean diet without Endopower were shortened and thickened compared to those of the birds fed with Endopower diet regardless of energy level. The results demonstrated that dietary Endopower improved body weight gain reduced abdominal fats and developed intestinal villi. Therefore it can be concluded that dietary supplementation of Endopower improves nutritive value of corn-soybean diet in broiler chicks.
