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

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

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

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

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