16. PACAP and airway regulation with special reference to smooth muscle and neutrophils
Sammanfattning : The investigations focus on the neuropeptidepituitary adenylate cyclase-activating peptide and its effects on airway regulation, with emphasis on smooth muscle relaxation and neutrophil activation and migration. In the nasal mucosa, PACAP-containing nerve fibers were localized invascular smooth muscle and close to seromucous glands. LÄS MER
17. Luminal Hypotonicity and Duodenal Functions : An Experimental Study in the Rat
Sammanfattning : After drinking water, the fluid quickly leaves the stomach thereby creating a hypotonic luminal environment in the duodenum. This in turn constitutes a potential threat to the integrity of the duodenal epithelium. It therefore seems highly likely that luminal hypotonicity activates physiological mechanisms that aim to increase luminal osmolality. LÄS MER
18. Interaction between the nervous and immune systems in allergic contact dermatitis : a clinical and experimental study with emphasis on the role of VIP and serotonin
Sammanfattning : The interaction between the nervous and immune systems was investigated in allergic contact dermatitis (ACD) with emphasis on the role of vasoactive intestinal peptide (VIP) and serotonin (S-HT). Dual dose-dependent effects of VIP on the migration of mononuclear and polymorphonuclear leukocytes were found. LÄS MER
19. Purification, structure and function of bioactive peptides
Sammanfattning : Peptides are vitally important molecules and many evoke cellular responses. The completion of several genome sequencing projects has revealed a number of new genes. LÄS MER
20. Neuromuscular function in the normal and inflamed colon. An experimental study in rat
Sammanfattning : Neuromuscular function of the longitudinal muscle layer of distal colon was investigated in segments from normal rats and from rats with colitis induced by dextran sulphate sodium (DSS) at 3% for 3 or 7 days or 5% for 7 days. The study was performed in vitro, on spontaneous tone, or after precontraction. LÄS MER
