  1. 16. PACAP and airway regulation with special reference to smooth muscle and neutrophils

    Författare :Johan Kinhult; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen; Otorhinolaryngology; allergy; neutrophils; smooth muscle; PACAP; airway regulation;

    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

  3. 17. Luminal Hypotonicity and Duodenal Functions : An Experimental Study in the Rat

    Författare :Liselotte Pihl; Olof Nylander; Gunnar Flemström; Mats Jodal; Uppsala universitet; []
    Nyckelord :Physiology; luminal alkalinization; mucosal permeability; osmolality; cyclooxygenase-2; rat; duodenum; jejunum; motility; enteric nervous system; Fysiologi;

    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

  4. 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

    Författare :Lena Bondesson Lundeberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :patch test; nickel sulphate; serotonin antagonists; VIP receptors; immunohistochemistry; ELISA; RIA; HPLC;

    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

  5. 19. Purification, structure and function of bioactive peptides

    Författare :Elo Eriste; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    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

  7. 20. Neuromuscular function in the normal and inflamed colon. An experimental study in rat

    Författare :Lars Börjesson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ATP; dextran sulphate sodium; DMPP; enteric nervous system; McN-A-343; nitric oxide; non-adrenergic; rat; second messenger; smooth muscle; VIP;

    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
