  1. 1. Elevers föreställningar om kroppens organ och kroppens hälsa utifrån ett skolsammanhang

    Författare :Pernilla Granklint Enochson; Gustav Helldén; Britt Lindahl; Schoultz Jan; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Science of education; Human body; Lower secondary school; Understanding of the human body; Health; Digestive organs; Excretions organs; Painkiller; Naturvetenskapernas didaktik; förståelse; grundskolans senare del; människokroppen; hälsa; matspjälkning; utsöndringsorgan; värktablett; Subject didactics; Ämnesdidaktik; Pedagogics and Educational Sciences; Pedagogik och Utbildningsvetenskap;

    Sammanfattning : Denna avhandling har fokus på 88 elevers föreställningar om vad som händer i kroppen då de äter en smörgås, dricker vatten och sväljer en värktablett. Sedan har jag studerat hur dessa föreställningar påverkar deras kunskaper vad det gäller kroppens fysiologi och deras ställningstagande i hälsofrågor. LÄS MER

  3. 2. Impact of the gut microflora on the digestive system in the suckling rat

    Författare :Frida Fåk; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; probiotics; prebiotics; antibiotics; lactobacilli; bacteria; intestinal permeability; Small intestine; maturation; weaning; suckling;

    Sammanfattning : The postnatal development of the gastrointestinal (GI) system in mammals is genetically programmed, but is, to an unknown extent, regulated by external factors such as the diet and the gut microflora. These factors can influence the growth of the GI tract, the age-related pattern of appearance of digestive enzymes and the decreased intestinal macromolecular permeability at gut closure, normally timed with weaning in young rodents.

  4. 3. Regulation of digestive organ. An experimental study on the role of CCK, Bile and EGF

    Författare :Bodil Ohlsson; Internmedicin - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; trophic effects; total parenteral nutrition; salivary glands; pancreaticobiliary diversion; pancreas; liver; intestinal mucosa; epidermal growth factor; cholecystokinin; biliodigestive shunt; Bile; bilary tract; serology; transplantation; Immunologi; serologi; Gastro-enterology; Gastroenterologi;

    Sammanfattning : Cholecystokinin (CCK) is known to exert secretory and trophic effects on the pancreas. Its release from the intestinal mucosa is regulated by pancresic proteases in the small intestine. However, knowledge about the type of responding exocrine cells and the time course of events during stimulation with CCK is lacking. LÄS MER

  5. 4. Imaging the pancreas : new aspects on lobular development and adult constitution

    Författare :Andreas Hörnblad; Ulf Ahlgren; Guy Rutter; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 1 diabetes; ß-cell mass; tertiary lymphoid organs; biomedical imaging; optical projection tomography; morphogenesis; pancreas development; gastric lobe; spleen development.; medicinsk genetik; Medical Genetics; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences; molekylär medicin genetik och patologi ; molecular medicine  genetics and pathology ;

    Sammanfattning : The mouse pancreas is a mixed exocrine and endocrine glandconsisting of three lobular compartments: the splenic, duodenal and gastric lobes. During embryogenesis, the pancreas forms from two progenitor populations located on the dorsal and ventral side of the primitive gut tube. LÄS MER

  7. 5. Induced Growth and Precocious Maturation of the Digestive System in Suckling Rats and Pigs after Exposure to Red Kidney Bean Lectin

    Författare :Ann Linderoth; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neuropsykologi; neurofysiologi; Neurologi; neurophysiology; neuropsychology; Neurology; Fysiologi; Physiology; Djurfysiologi; Animal physiology; sucrase; lactase; amylase; trypsin; weaning; small intestine; glucocorticoids; endocytosis; dissacchridases; intestinal permeability; PHA; pancreas; Development; phytohaemagglutinin;

    Sammanfattning : The timing of the postnatal development of the gastrointestinal (GI) tract in mammals is influenced by dietary and hormonal factors. It was hypothesized that accelerated GI cell turnover during maturation would result in a precoucios conversion to more mature digestive functions. LÄS MER
