BACKGROUND A new subline of the senescence accelerated mouse (SAM) P1/Yit strain has been established which shows spontaneous enteric inflammation under specific pathogen free (SPF) conditions. AIMS To elucidate the pathogenesis of enteric inflammation in this new subline. METHODS The SPF and germ free (GF) SAMP1/Yit strains were used. Histological, immunological, and microbiological charac...

We report a case of immunoglobulin G4 (IgG4)-related sclerosing disease involving the pancreas, liver and salivary glands. Massive infiltration of IgG4-expressing plasma cells was seen in the liver and submandibular lymph nodes. Interestingly, accumulation of IgG4-expressing plasma cells was also seen in the colon and terminal ileum. Peripheral blood mononuclear cells (PBMCs) isolated from this...

In a series of five 17-d replicate trials, a total of 54 cannulated and 12 noncannulated pigs were used to determine the effects of weaning age (17 d or 24 d) on pH, dry matter percentage, aerobic and anaerobic microflora, lactate, and volatile fatty acid (VFA) concentrations in the jejunum, ileum, and cecum of weanling pigs. At -14 d of age, cannulated pigs were surgically fitted with T-cannul...

The study aimed to assess the effects of dietary supplementation microencapsulated L. acidophilus and plantarum their combination on growth performance, organ development, diarrhoea incidences, blood profiles, intestinal histomorphology microflora in weaned piglets. For that, 160 piglets with an average body weight (BW) 8.52 ± 0.15 kg were divided into four groups (40 piglets/group) allotted on...

o objective: many biological studies have been done to determine the activity of medicinal plants on gastrointestinal function. since acetylcholine is the major transmitter involved in the gastrointestinal motility and there are some evidences regarding the cholinergic modulatory effect of hops extract, in the present study spasmolytic and antispasmodic action of hops(humulus lupulus) on acetyl...

The aim of this study was to evaluate the effects different levels silver nanoparticles (Ag-NPs) coated on zeolite performance, gastrointestinal microflora, heterophile lymphocyte ratio and humoral immune system responses broiler chickens. Three hundred seventy-five chicks (Cobb 500) in a completely randomised design were distributed five diets: 1) basal diet, 2) diet containing 1% 3, 4 5) with...

this study was conducted to compare the effect of various commercial in-feed disinfectants on layer performance, intestinal microflora, and egg cholesterol. one hundred and eight layer hens (lsl, 24 wks of age) were divided into six groups consisting: control, formaycin-200 ppm, formalin-200 ppm, and nanosilver in feed-15 ppm or drinking water-7.5 ppm. there were no differences between experime...

rosa damascena flower is widely used for gastrointestinal (gi) disorders. however, its pharmacological action on isolated ileum has not been studied. in this research, the effect of extract of flower petals of r. damascena mill. growing in kashan, iran, on ileum motility was investigated. hydroalcoholic extract was prepared by percolation method. a section of rat ileum was suspended in an organ...

The aim of this thesis was to estimate the presence of Salmonella and enterotoxigenic Escherichia coli in piglets, the effect of fermented liquid feed and rice distiller’s residue as a dietary modulation of the microbial population, the presence of microflora at different sites of the digestive tract, digestibility, and to evaluate the performance of pigs under small-scale farm conditions. The ...
