An experimental study was done to investigate the spontaneous movements to the isolated ileum with liquid extracts of Samchulgunbitang. Then the action of gastric ulcer, gastric-juice secretion, the free acidity, total acidity, pepsin output, the transport ability in the intestine, analgesic effect and sleeping time were measured. The following results were obtained; 1. As to the spontaneous movements in the isolated ileum, the effect of contraction against suppression was recognized. 2. The effects of contraction against suppression induced by acetylcholine chloride and barium chloride were recognized on the gastric funds strip significantly. 3. The preventive effect of Samchulgunbitang on the pylorus-lightedulcer in rat was recognized significantly. 4. The anti-ulcer effect of Samchulgunbitang was not recognized on the gastric ulcer caused by indomethacin. 5. The effects of decreasing on the secretion gastric juice, the free acidity, total acidity and pepsin output of Samchulgunbitang were recognized significantly. 6. The transport rate in the small intestine of Samchulgunbitang was decreased. 7. The transport rate in the large intestine of Samchulgunbitang was increased. 8. The analgesic effect of Samchulgunbitang caused by acetic acid was recognized significantly. 9. The sleeping time caused by pentobarbital-Na of Samchulgunbitang was prolonged significantly. According to the results, it is considered that the Samchulgunbitang has effects of gastric ulcer, chronic gastritis, hyper-acidity, gastroptosis such as abdominal discomfort, gastric acid, indigestion and anorexia.

Different levels of dietary mannanoligosaccharide (Bio-MOS, Alltech Inc.) were evaluated for their efficacy on performance and gut development of broiler chickens during a 6-week experimental period. Experimental diets contained (g MOS/kg diet) a low (0.5 g during the entire period), medium (1 g during the entire period), high (2 g during the entire period), or step down (2 g in the first week; 1 g in the second and third week; 0.5 g in the last three weeks) level of MOS. Control diets included a negative and a positive control (zinc bacitracin, ZnB, 50 ppm and 30 ppm in the first and last three weeks, respectively). MOS supplementation improved the growth performance of young birds and the effects became less when the birds got older. The growth response of birds was more obvious at the high dosage level of MOS treatment than the other MOS treatments and the growth performance of birds fed on the high MOS diet was comparable to that of birds fed on the ZnB diet. Depending on the dosage level and the age of birds, MOS seemed to reduce the size of the liver and the relative length of the small intestine but did not affect the relative weight of the other visceral organs (proventriculus, gizzard, pancreas, bursa and spleen) and that of the small intestine. A numerical increase in the small intestine digestibility of nutrients was noticed in the young birds fed on the MOS diet(s), but not in the older ones. Medium and/or high MOS treatment also increased the villus height of the small intestine of birds at different ages. Similar results were observed on the ZnB treatment. However, MOS and ZnB affected caecal VFA profile in different ways. MOS increased, or tended to increase, whereas ZnB reduced individual VFA concentrations in the caeca.

Glucose is the main energy source for mammalian cells and its absorption is co-mediated by two different families of glucose transporters, sodium/glucose co-transporters (SGLTs) and facilitative glucose transporters (GLUTs). Here, we report the cloning and tissue distribution of porcine GLUT2. The GLUT2 was cloned by RACE and its cDNA was 2,051 bp long (GenBank accession no. EF140874). An AAATAA consensus sequence at nucleotide positions 1936-1941 was located upstream of the poly $(A)^+$ tail. Open reading frame analysis suggested that porcine GLUT2 contained 524 amino acids, with molecular weight of 57 kDa. The amino acid sequence of porcine GLUT2 was 87% and 79.4% identical with human and mouse GLUT2, respectively. GLUT2 mRNA was detected at highest level in porcine liver, at moderate levels in the small intestine and kidney, and at low levels in the brain, lung, muscle and heart. In the small intestine, the highest level was in the jejunum. In conclusion, the mRNA expression of GLUT2 was not only differentially regulated by age, but also differentially distributed along the small intestine of piglets, which may be related to availability of different intestinal luminal substrate concentrations resulting from different food sources and digestibility.

Objective: The gastrointestinal tract of sheep contain complex microbial communities that influence numerous aspects of the sheep's health and development. The objective of this study was to analyze the composition and diversity of the microbiota in the gastrointestinal tract sections (rumen, reticulum, omasum, abomasum, duodenum, jejunum, ileum, cecum, colon, and rectum) of sheep. Methods: This analysis was performed by 454 pyrosequencing using the V3-V6 region of the 16S rRNA genes. Samples were collected from five healthy, small tailed Han sheep aged 10 months, obtained at market. The bacterial composition of sheep gastrointestinal microbiota was investigated at the phylum, class, order, family, genus, and species levels. Results: The dominant bacterial phyla in the entire gastrointestinal sections were Firmicutes, Bacteroidetes, and Proteobacteria. In the stomach, the three most dominant genera in the sheep were Prevotella, unclassified Lachnospiraceae, and Butyrivibrio. In the small intestine, the three most dominant genera in the sheep were Escherichia, unclassified Lachnospiraceae, and Ruminococcus. In the large intestine, the three most dominant genera in the sheep were Ruminococcus, unclassified Ruminococcaceae, and Prevotella. R. flavefaciens, B. fibrisolvens, and S. ruminantium were three most dominant species in the sheep gastrointestinal tract. Principal Coordinates Analysis showed that the microbial communities from each gastrointestinal section could be separated into three groups according to similarity of community composition: stomach (rumen, reticulum, omasum, and abomasum), small intestine (duodenum, jejunum, and ileum), and large intestine (cecum, colon, and rectum). Conclusion: This is the first study to characterize the entire gastrointestinal microbiota in sheep by use of 16S rRNA gene amplicon pyrosequencing, expanding our knowledge of the gastrointestinal bacterial community of sheep.

Reported here are the effects of added formic acid on inhibitory effect of Salmonella gallinarum in poultry feed. Two experiments were conducted to investigate the viability of S. gallinarum and pH of poultry feed using different dietary formic acid levels (0.0, 0.5, 1.0 and 1.5%) on inhibitory effect of S. gallinarum in broiler feed. Experiment one was conducted to investigate the viability of S. gallinarum and pH of artificially contaminated diet at 0, 1, 3, 5 and 7 days after treatment in vitro. Formic acid showed a significant (p<0.05) reduction in the viability for all treatments with time after treatment. Various formic acid levels in vitro showed a reduction in the pH of the diet depending upon the concentration of treated acid, and the diet remained acidic below the growth range of S. gallinarum. This meant that the bacterial cells were exposed to stressful conditions that made them unable to grow. Experiment two was conducted to find out the effect of dietary formic acid levels on S. gallinarum colonization and pH in the contents of crop, small intestine, large intestine and ceca and mortality rate of broiler chicks at 7, 14 and 21 days of age when fed artificially contaminated diet with S. gallinarum. The numbers of S. gallinarum re-isolated from all treated groups except in groups treated with 0.5% formic acid, decreased significantly (p<0.05) compared with the control group. The treatment significantly (p<0.05) lowered the pH of the crop, small intestine, large intestine and ceca contents in all groups except the groups treated with 0.5% formic acid compared with the control. All treated groups showed a significant (p<0.05) reduction in overall mortality rate during the experimental period (3 to 21 days) compared with the control. The results indicate that addition of formic acid in a total concentration of 1.5% to the diet of newly hatched broiler chicks significantly decreases the contamination of diet with S. gallinarum.

Aqueous extract of antidiarrhoeal formulation (ADF) containing Holarrhena antidysentrica, Aegle marmelos and Punica granatum was investigated for antidiarrhoeal activity against charcoal-induced gut transit, serotonin-induced diarrhoea and $PGE_2-induced$ small intestine enteropooling in rats. The control, standard and test groups of experimental animals were administered with normal saline (p.o.), diphenoxylate hydrochloride (5 mg/kg, p.o.) and ADF (250 mg and 500 mg/kg, p.o.) respectively except the control group of $PGE_2-induced$ small intestine enteropooling which received only 5% ethanol in normal saline (i.p.). Charcoal (10 ml/kg, p.o.) and serotonin $(600\;{\mu}g/kg,\;i.p.)$ were administered after 30 min, while $PGE_2\;(100\;{\mu}g/kg,\;p.o.)$ was administered immediately afterwards. The distance traveled by charcoal in small intestine was measured after 15 and 30 min of charcoal administration, diarrhoea was observed every 30 min for six hour after serotonin administration and the volume of intestinal fluid was measured after 30 min of $PGE_2$ administration. Oral administration of ADF significantly inhibited the frequency of defaecation and decreased the propulsion of charcoal meal through the gastrointestinal tract, reduced the wetness of faecal dropping in serotonin-induced diarrhoea and also reduced the $PGE_2-induced$small intestine enteropooling. ADF may have potential to reduce the diarrhoea in rats.

This Study was conducted to assess the single dose toxicity of DA-125, a new anthracycline anti-cancer agent, in rats and mice. The Drug was administered once intravenously to both sexes of rats and mice. Then followed a 14-day period of observation. The $LD_{50}$ Values (95% confidence limit) were estimated to be 60.9 mg/kg (57.5~64.3 mg/kg) for male rats and 60.2 mg/kg (56.2~64.5 mg/kg) for female rats, and 85.8 mg/kg (81.0~90.9 mg/kg) for male mice and 84.5 mg/kg (78.2~91.9 mg/kg) for female mice. Both sexes of rats and mice given the drug revealed the clinical sign of decreased locomotor activity, emaciation, hair loss, red-dish brown urine, salivation, and watery diarrhea. In addition, body weight from the next day to the 7th day tended to be decreased slightly in rats and mice treated with DA-125. Death occurred from the next day after administration to the 12th day. Macroscopically, congestion of gastrointestinal organ, lung, and adrenal glands were found in both sexes on the dead rats and mice. Histopathological examination of dead rats manifested atrophy of spleen, hypoplasia of bone marrow, hypcplasia and necrosis of lymphocyte in thymus, atrophy of villi in small intestine (duodenum, jejunum, and ileum), hyperplasia of granular epithelium in small intestine, degeneration of germinal epithelium in testis, defer oration of tubular epithelium in kidney, and vacuolation and myolysis of myocardium in heart. Histopathological examination of dead mice revealed hypoplasia of spleen and mesenteric lymph node, local necrosis of liver, atrophy of villi in small intestine, hyperplasia of glandular epithelium in small and large intestine, degeneration of tubular in kidney, degeneration of germinal cells in testis, and slight vacuolar degeneration of myocardium in heart.

Oxidative stress plays an important role in the pathogenesis of various diabetic complications and small intestine is vulnerable to damage resulting in morphological and functional changes. In this study, the effects of Asystasia gangetica leaf extract (AGLE) on oxidative stress status in small intestine of diabetic rats were examined. The leaves of Asystasia gangetica was extracted with 70% ethanol. Oral administration of AGLE once daily (100 mg/kg and 200 mg/kg b.w.) for 28 days to diabetic rats significantly (P < 0.05) increased antioxidant levels of catalase, superoxide dismutase, glutathione peroxidase, glutathione, GSSH, carbohydrate metabolizing enzyme, glucose-6-phosphate dehydrogenase. The increased levels of protein carbonyl content, lipid peroxidation and xanthine oxidase/xanthine dehydrogenase in diabetic rats were reverted back to near normal levels on treatment with AGLE. Both doses of AGLE offered significant activity (P < 0.01) against oxidative damage and were comparable with standard, glibenclamide. The results revealed the occurrence of oxidative stress in small intestine during diabetes and suggest the potential of AGLE as an antioxidant in protecting the tissue defense system against oxidative damage in streptozotocin-induced diabetes.
