backgrounds: genus trichostrongylus (nematoda: trichostrongylidae) is one of the most impor­tant zoonotic nematodes with wide geographic distribution in the world. the purpose of the present study was to describe morphological and morphometrical characteristics of male trichostrongylus species, currently prevalent in domestic ruminants of khuzestan province , south­west iran. methods: gastro-in...

Sediments are potentially the internal source that supply nutrients to water in lentic semi-lentic ecosystems. The understanding of factors cause temporal changes sediment properties is critical for management. This study investigated spatial variations and relation their controlling bodies Ishikari River, Northern Japan. Sediment data 29 were measured twice (around 2005 2019) properties, compa...

BACKGROUND Strains of Bacteroides fragilis producing a 20 kDa protein toxin (B fragilis toxin (BFT) or fragilysin) are associated with diarrhoea in animals and humans. Although in vitro results indicate that BFT damages intestinal epithelial cells in culture, the effects of BFT on native human colon are not known. AIMS To examine the electrophysiological and morphological effects of purified ...

PURPOSE To investigate the changes in the intestinal epithelium of rats, when submitted to the ischemia of varied time and scheduled reperfusion. METHODS For this purpose, the following groups were established six groups: control, 10, 20, 30, 40, 60 minutes of ischemia and reperfusion time (24 hours). Their intestines being resected for histopathological analysis: the length and width of the ...

During intestinal absorption, dietary polyglutamyl folates are hydrolyzed to monoglutamyl folates by pteroylpolyglutamate hydrolase (folate conjugase). This enzyme is present in the brush border and intracellular fractions of human jejunal mucosa. We compared the activities of brush border and intracellular folate conjugase (BBFC and ICFC), and other mucosal enzymes in the jejunum in continuity...

An experiment was carried out to study the preventive effect of bacterial meal (BM) produced from natural gas against plant-induced enteropathy in Atlantic salmon (Salmo salar). Salmon were fed a diet based on fish meal (FM) or seven diets with 200 g/kg solvent-extracted soyabean meal (SBM) to induce enteritis in combination with increasing levels of BM from 0 to 300 g/kg. Salmon fed a SBM-cont...

Duodenal endocrine cells in 11 patients with familial amyloid associated polyneuropathy (FAP) were compared with those in 12 healthy volunteers by means of immunohistochemistry and morphometry. The total endocrine cell content, determined by the argyrophilic reaction and chromogranin A immunoreactivity, was significantly reduced in FAP patients compared with controls. There was a significant re...

BACKGROUND Two-layer intestinal anastomosis increases the inflammatory response while single-layer anastomosis results in a better wound healing. However the four main kinds of stitches which may be chosen in performing single layer intestinal sutures never before had been comparatively studied. AIM To compare the four more commonly used types of single layer surgical anastomosis sutures of t...

OBJECTIVE To measure the thickness of the crypts and quantify the number of goblet cells of the colonic mucosa with and without intestinal transit, relating them to exclusion time. METHODS Sixty Wistar rats were divided into three groups of 20 animals each according to the time of the final operation for the removal of the colon, in six, 12 or 18 weeks. In each group 15 animals underwent colo...
