  • The effect of genotype, fibre level and fibre source on gut morphology, environment and microflora was studied using 18 Mong Cai (MC) and 18 Landrace${\times}$Yorkshire (LY) pigs, aged around 60 d. The diets were based on maize, rice bran, soybean meal, fish meal and soybean oil, and cassava residue (CR) or brewer's grain (BG) as fibrous ingredient sources in the high-fibre diets (HF). A low-fibre diet (LF), containing around 200 g NDF/kg dry matter (DM), was formulated without CR and BG as feed ingredients. The HF diets (HF-CR and HF-BG) were formulated to contain around 270 g NDF/kg DM. The experiment was arranged according to a $2{\times}3$ factorial completely randomized design with six replications, and lasted 30 d. Crypt density in ileum was lowest (p<0.05) and villus height in jejunum and ileum were the greatest (p<0.05) in pigs fed diet HF-BG. Villus width in ileum was greatest in pigs fed diets HF-CR and HF-BG (p<0.05). Lactic acid bacteria (LAB) counts in stomach were greatest (p<0.05) and E. coli counts in ileum and colon were lowest (p<0.05) in pigs fed diet HF-CR. The concentration of total organic acids in ileum, caecum and colon were greatest (p<0.05), and pH in ileum and colon were lowest (p<0.05) in pigs fed diet HF-CR. Crypt density in ileum was lowest, and villus height in ileum and villus width in jejunum and ileum was greatest in LY pigs (p<0.05). LAB counts in stomach and ileum were greatest, and E. coli counts in ileum were lowest in MC pigs (p<0.05). The concentration of total organic acids in ileum, caecum and colon were greatest (p<0.05) and pH lowest (p<0.05) in MC pigs.

  • Segmental intestinal dilatation is rare, which causes symptom of bowel obstruction and requires resection. The resection is not only diagnostic but also curative procedure. Recently, author experienced 2 cases of segmental dilatation of the ileum due to focal agenesis of the intestinal muscularis in 7 day & 4 day-old female neonates. The post operative recovery was excellant in the first case after resection of dilated ileum(15cm in length) and end to end anastomosis, and discharged at 20th day. But in the second case, the passage disturbance was not relieved after resection of dilated ileum (30cm in length), and author re-resected 80cm more of dilated proximal ileum at 2 weeks after the first operation. This baby discharged after diarrhea control with Loperin on 1 month after the second operation. Final histologic examination showed 1) normal population of ganglion cells in both narrowed & dilated ileum in both cases. 2) focal abscence of muscularis propria in both cases. 3) relative hypertrophy of inner circular muscle layer and thinned, multiple fragmented outer longitudinal muscle layer in case 2.

  • To clarify whether nizatidine, a $H_2$ receptor antagonist, has the cholinergic activity, the effects of nizatidine on the guinea pig ileum and on the acetylcholinesterase in human serum were studied. And, the mechanism of excitatory effect of nizatidine on the cholinergic system in ileum was also studied. Nizatidine caused a concentration-dependent contractile response by the guinea pig ileum. The $EC_{50}\;was\;53\;{\mu}M$ and the maximum response was at $300\;{\mu}M$. Ranitidine also caused a contractile response by the guinea pig ileum, but cimetidine and famotidine did not. The pretreatment with $H_1$ receptor antagonist did not affect the actions of nizatidine on the guinea pig ileum, but the pretreatment with atropine completely blocked them. Nizatidine significantly enhanced the acetylcholine-induced response of the guinea pig ileum, but not the pilocarpine-induced response. Nizatidine did not affect the histamine-induced response of the guinea pig ileum. Nizatidine still exerted the small excitatory effect on the guinea pig ileum pretreated with the high concentration of physostigmine. Nizatidine significantly inhibited the acetylcholinesterase in human serum. These results suggest that nizatidine exerts an excitatory effect on guinea pig ileum which seems to be associated with the cholinergic system, probably through an indirect mechanism, inhibition of acetylcholinesterase and/or increased release of acetylcholine.

  • Antimuscarinic agent like antispasmodic actions of licorice alkaloidal fraction, obtained from the Glycyrrhiza glabra L., was compared with that of atropine quantitatively. For this purpose, the author calculated the kinetic constants and $ED_{50}$ for acetylcholine antagonism by these drugs on rat ileum and guinea-fig ileum longitudinal muscle according to Paton's theoretical equations describing the combination of an antagonist drug with its receptors. The results are as follows. 1. On rat ileum. a) Licorice alkaloidal fraction $K_1$ (association rate constant)=$4.078{\times}10^2\;(s^{-1}\;gm^{-1}\;ml)$ $K_2$ (dissociation rate constant)=$6.986{\times}10^{-4}\;(s^{-1})$ $ED_{50}(K_2/K_1)=1.772{\times}10^{-6}(gm/ml)$ b) Atropine $K_1=5.136{\times}10^6$, $K_2=7.714{\times}10^{-4}$, $ED_{50}=1.408{\times}10^{-10}$ 2. On guinea-pig ileum longitudinal muscle a) Licorice alkaloidal fraction $K_1=1.30{\times}10^2$, $K_2=1.25{\times}10^{-3}$ $ED_{50}=9.58{\times}10^{-6}$ b) Atropine $K_1=5.75{\times}10^6$, $K_2=1.54{\times}10^{-3}$ $ED_{50}=2.68{\times}10^{-10}$ Above results present that 1 r of licorice alkaloidal fraction has equal fotency of acetylcholine antagonism with $8.5{\times}10^{-5}r$ of atropine on rat ileum, $2.8{\times}10^{-5}r$ on guinea-pig ileum longitudinal muscle. This facts suggest that the site and numbers of licorice alkaloid receptors of guinea-pig ileum are different from that of rat ileum. Besides, it also gives a suggestion that licorice alkaloidal fraction may be a partial antagonist on guinea-pig ileum in this experimental conditions.

  • Hypospadias is a congenital malformation of the male genitalia. The reconstructive objectives are to obtain voiding with laminar flow and satisfactory sexual function. Several urethroplasty techniques have been described, but for perineal or revisional cases no single technique has shown robust success. In this study, we describe the expanded use of intestinal flaps for urethral reconstruction and report a peculiar request from a patient to undergo peno-urethral separation after successful hypospadias repair with a free ileum flap. A 51-year-old male patient with perineal hypospadias underwent several urethral reconstructive procedures with poor outcomes. A free ileum flap was attempted as a substitute for the urethra. Following successful reconstruction, separation of the neo-urethra (ileum) from the penile body was performed to address the patient's sexual expectations. A free ileum flap proved to be a reliable urethral substitute in perineal hypospadias reconstruction, with a successful outcome. The peno-urethral separation with the creation of an "accessory penis," however peculiar, optimized the results in terms of both sexual and urinary function. Anatomical restoration of the urethra and patient-reported expectations are the key to successful hypospadias reconstructive procedures. Sexual function outcomes and the patient's perception of success should not be underestimated, even when urinary function has been restored.

  • Bacterial diversity was studied using PCR-DGGE, cloning and sequencing. DNA was isolated from digesta samples from stomach, ileum and colon of 28 weaned piglets (Large White${\times}$Mong Cai) fed dry control feed, naturally fermented liquid feed (FE) and a liquid diet with inclusion of rice distiller's residue feed. General bacterial diversity was described using DGGE analysis of the V3 region of 16S rDNA. The microbial populations in the stomach and the ileum were considerably influenced by the diet, while only marginal effects were observed in the colon. There was a large variation of the microbial flora in the stomach between individuals fed non-fermented diets. In contrast, animals fed diet FE had a more uniform microbial flora in the stomach and the ileum compared to the other diets. In total 47 bands from the DGGE profiles were cloned. In stomach, most frequently lactic acid bacteria were found. Feeding diet FE resulted in the occurrence of Pediococcus species in stomach and ileum. In pigs fed the other diets, Lactobacillus gallinarum, Lactobacillus johnsonii and Lactobacillus fermentum were found in stomach and ileum. Most of the sequences of bands isolated from colon samples and several from ileum matched to unknown bacteria, which often grouped within Prevotellaceae, Enterobacteriaceae, Bacteroidaceae and Erysipelotrichaceae. This study demonstrates that fermented liquid feed affects bacterial diversity and the specific microflora in stomach and ileum, which provides a potential to modulate the gut microflora with dietary means to increase the abundance of beneficial bacteria and improve piglets' health.

  • The inhibitory action of oxymetazoline on the spontaneous movements of isolated intestinal strips of the rabbit and the effects of antagonists upon the oxymetazoline actions were assessed with recordings through both isometric and isotonic transducers, and comparisons were made between both methods of recording. There were significant differences between the slopes of regression equations calculated from log dose response curves of oxymetazoline obtained from jejunum and those from ileum. But no difference was noted between both recordings either through isotonic transducer or through isometric transducer. The $ID_{50}$ of oxymetazoline obtained from the recording through isotonic transducer was $6.31{\times}10^{-7}M$ in jejunum and $3.16{\times}10^{-8}M$ in ileum. The recording through isometric transducer gave the values of $5.01{\times}10^{-7}M$ in jejunum and $1.07{\times}10^{-8}M$ in ileum. The $pA_2$-values of prazosin to oxymetazoline calculated from the recording through isotonic transducer were 8.13 in jejunum and 8.31 in ileum and the recording through isometric transducer gave the values of 7.29 and 8.26 in jejunum and ileum, respectively. The $pA_2$-values of phentolamine to oxymetazoline obtained from the recording through isotonic transducer were 8.18 in Jejunum and 9.31 in ileum and those from the recording through isometric transducer were 7.75 and 8.13 in jejunum and ileum, respectively. These results indicate that there are no significant differences between recordings either through isotonic transducer or through isometric transducer in assessing inhibitory responses of intestinal movement to certain drugs.
