  • Human milk, which nourishes the early infants, is a source of bioactive components for the infant growth, development and commensal formulation as well. Human milk oligosaccharide is a group of complex and diverse glycans that is apparently not absorbed in human gastrointestinal tract. Although most mammalian milk contains oligosaccharides, oligosaccharides in human milk exhibit unique features in terms of their types, amounts, sizes, and functionalities. In addition to the prevention of infectious bacteria and the development of early immune system, human milk oligosaccharides are able to facilitate the healthy intestinal microbiota. Bifidobacterial intestinal microbiota appears to be established by the unilateral interaction between milk oligosaccharides, human intestinal activity and commensals. Digestibility, membrane transportation and catabolic activity by bacteria and intestinal epithelial cells, all of which are linked to the structural of human milk oligosaccharides, are crucial in determining intestinal microbiota.

  • This study was attempted to investigate the effect of cromakalim(CRK). $K^{-}$ channel opener, and glibenclamide(GLY), $K^{-}$ channel blocker, on intestinal function of rabbit. CRK supressed the tension and spontaneous movement of intestinal strips. Such CRK strengthened the tension and spontaneous movement of strips potentiated by acetylcholine, whereas more attenuated those weakened by dopamine. GLY augmented the tension, did not affect to the spontaneous movement of strips. GLY inhibited the acetylcholine-potentiated responses of tension and spontaneous movements in intestinal strips. GLY blocked the weakened responses of tension, while did not affect to the dopamine-weakened responses of spontaneous movements in intestinal strips. The present studies suggest that $K^{-}$ channel opening suppresses intestinal movements, whereas it's blockade enhances intestinal movements in rabbit.abbit.

  • Vibrio vulnificus, a Gram-negative estuarine bacterium, is the causative agent of food-borne diseases, such as life-threatening septicemia. V. vulnificus penetrating into the intestinal epithelial barrier stimulates an inflammatory response in the adjacent intestinal mucosa. Therefore, interaction between V. vulnificus and intestinal cells is important for understanding of both the immunology of mucosal surfaces and V. vulnificus. In this study we investigated the effects of V. vulnificus infection on cytokine gene expression of human intestinal epithelial cells, Caco-2 and INT-407 cells. (omitted)

  • The aim of the present study was to examine the effect of micellar systems on the absorption of beta-lapachone (b-lap) through different intestinal segments using a single-pass rat intestinal perfusion technique. B-lap was solubilized in mixed micelles composed of phosphatidylcholine and sodium deoxycholate, and in sodium lauryl sulfate (SLS)-based conventional micelles. Both mixed micelles and SLS micelles improved the in situ permeability of b-lap in all intestinal segments tested although the mixed micellar formulation was more effective in increasing the intestinal absorption of b-lap. The permeability of b-lap was greatest in the large intestinal segments. Compared with SLS micelles, the effective permeability coefficient values measured with mixed micelles were 5- to 23-fold higher depending on the intestinal segment. Our data suggest that b-lap should be delivered to the large intestine using a mixed micellar system for improved absorption.

  • Present study aimed to investigate the effect of curcumin-pretreatment on intestinal I/R injury and on intestinal mucosa barrier. Thirty Wistar rats were randomly divided into: sham, I/R, and curcumin groups (n=10). Animals in curcumin group were pretreated with curcumin by gastric gavage (200 mg/kg) for 2 days before I/R. Small intestine tissues were prepared for Haematoxylin & Eosin (H&E) staining. Serum diamine oxidase (DAO) and tumor necrosis factor (TNF)-${\alpha}$ levels were measured. Expression of intestinal TNF-${\alpha}$ and tight junction protein (ZO-1) proteins was detected by Western blot and/or immunohistochemistry. Serum DAO level and serum and intestinal TNF-${\alpha}$ leves were significantly increased after I/R, and the values were markedly reduced by curcumin pretreatment although still higher than that of sham group (p<0.05 or p<0.001). H&E staining showed the significant injury to intestinal mucosa following I/R, and curcumin pretreatment significantly improved the histological structure of intestinal mucosa. I/R insult also induced significantly down-regulated expression of ZO-1, and the effect was dramatically attenuated by curcumin-pretreatment. Curcumin may protect the intestine from I/R injury through restoration of the epithelial structure, promotion of the recovery of intestinal permeability, as well as enhancement of ZO-1 protein expression, and this effect may be partly attributed to the TNF-${\alpha}$ related pathway.

  • Intestinal obstruction secondary to intraabdominal adhesion is a well-known postoperative complication occurring after appendectomy. The aim of this study was to measure the incidence and clinical manifestations of mechanical intestinal obstruction after appendectomy for perforated appendicitis. We reviewed all of the children (age <16 years) who had been treated for appendicitis at Asan Medical Center between January 1996 and December 2001. Inclusion criterion included either gross or microscopic evidence of appendiceal perforation. Exclusion criteria were interval appendectomy, and patients immune compromised by chemotherapy. Associations of intestinal obstruction with age, sex, operation time, and use of peritoneal drains were analyzed. Four hundred and sixty two open appendectomies for appendicitis were performed at our department. One hundred and seventeen children were treated for perforated appendicitis (78 boys, 39 girls). The mean age was 8.9 years (range 1.5 to 14.8 years). There were no deaths. Eight patients were readmitted due to intestinal obstruction, but there was no readmission due to intestinal obstruction in patients with non-perforated appendicitis. The interval between appendectomy and intestinal obstruction varied from 12 days to 2 year 7 months. Four patients needed laparotomies. In three of four, only adhesiolysis was performed. One child needed small bowel resection combined with adhesiolysis. There was no significant association between age or sex and the development of intestinal obstruction. This was no association with operative time or use of peritoneal drain. Patients who required appendectomy for perforated appendicitis have a higher incidence of postoperative intestinal obstruction than those with nonperforated appendicitis. For the patients with perforated appendicitis, careful operative procedures as well as pre and postoperative managements are required to reduce adhesions and subsequent bowel obstruction.

  • Objectives : The purpose of this study was to observe the effects of acupuncture and electro-acupuncture(EA) at $LI_{11}$ on intestinal motility in rats. Methods : We made over-activated and suppressed state of intestinal motility with carbachol and loperamide in rat and carried out acupuncture with needle retained(NR), low frequency(2 Hz) EA and high frequency(100Hz) EA at $LI_{11}$ before or after the administration of carbachol or loperamide. The charcoal travel rate was measured to evaluate the intestinal motility. Results : 1. NR, 2Hz EA and 100Hz EA at $LI_{11}$ showed no significant influences on intestinal motility of rat in normal state. 2. All of the pre-treatment and post-treatment of NR, 2Hz EA and 100Hz EA at $LI_{11}$ showed no significant effects than control group on intestinal motility of rat which was over-activated with carbachol. 3. The pre-treatment of 2Hz EA and 100Hz EA at $LI_{11}$ on intestinal motility of rat which was suppressed with loperamide showed no significant influences but in the L-$LI_{11}$-EA(L) and L-$LI_{11}$-EA(H) groups, intestinal motility was significantly increased than L-control group. Conclusions : These results suggest that acupuncture and EA on $LI_{11}$ have preventive effect and therapeutic effect on suppressed intestinal motility, and EA is more effective than NR.
