  2. 11. Developmental and methodological aspects of intestinal and pancreatic function in pigs and rats

    Author : Klas Rådberg; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; macromolecule; endocytosis; FITC-dextran; secretion; mucosa; CCK; pancreas; disaccharidase; intestinal permeability; lectin; morphometry; Animal physiology; Djurfysiologi;

    Abstract : The gastrointestinal tract has two opposing functions; to effectively absorb nutrients and to act as a safety barrier against hazardous substances in the environment. After birth these functions develops gradually. READ MORE

  4. 12. Regulation of the exocrine pancreas in growing pigs, with special emphasis on entero-pancreatic reflexes

    Author : Lena Evilevitch; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kidney bean lectin; Animal physiology; Djurfysiologi; duodenum; entero-pancreatic reflex; insulin; lipas; amylas; trypsin; weaning; development; maturation; inhibition; CCK-receptors; Exocrine pancreas; CCK; pig;

    Abstract : The regulation of the exocrine pancreas has been under thorough investigation for many decades. In rats, cholecystokinin (CCK) is considered to be the major gut hormone stimulating the pancreas to releasing the digestive enzymes. READ MORE

  5. 13. Biological Rhythms of Pancreatic Secretion in Young Pigs with empahasis to the time around weaning

    Author : Mary-Jane Sebabatso Thaela; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volume; Ultradian; Protein; Pancreas; Pig; IRCT; Insulin; Infradian; Glucose; Circadian; Chymotrypsin; Biologic week and Half-week; Chronome; Animal physiology; Djurfysiologi;

    Abstract : When the time structure (chronome) of pancreatic secretion was studied after weaning in 5-week-old pigs, the zero-amplitude (no-rhythm) assumption was rejected for the about-weekly (circaseptan, CS) and about-half-weekly (circasemiseptan, CSS) chronome components. When the data were assessed individually on a day-to-day basis, a 24-hour component was suggested (P. READ MORE

  6. 14. Lung mechanics in the aging lung and in acute lung injury. Studies based on sinusoidal flow modulation

    Author : Ulrika Bitzén; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostics; Diagnostik; acute lung injury; lung mechanics; acute respiratory distress syndrome; intensivvård; Anestesiologi; intensive care; Anaesthesiology; Andningsorganen; Respiratory system; Fysiologi; Physiology; flow regulation; method; lung resistance; compliance; aging;

    Abstract : Knowledge about lung mechanics is of interest in intensive care to adjust mechanical ventilation and in the lung laboratory for diagnostics and evaluation of patients with various kinds of respiratory diseases. In mechanical ventilation a single inspiratory elastic pressure-volume (Pel/V) curve is difficult to interpret due to continuing re-expansion of collapsed lung units over a large pressure interval.

  7. 15. Development and regulation of alveolar fluid clearance in the guinea pig

    Author : Andreas Norlin; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; oxytocin-induced preterm labor; IRDS; fetal lung fluid; preterm lung development; amiloride-sensitive sodium channels; beta-adrenergic stimulation; alveolar epithelium; Animal physiology; Djurfysiologi;

    Abstract : Alveolar fluid clearance is driven by active absorption of Na+ across the alveolar epithelium. Development and hormonal regulation of alveolar fluid clearance over 1 hour was studied by instillation of a protein-containing, isosmolar fluid into lungs of fetal, newborn, and adult guinea pigs.
