  1. 16. Histamine receptors and neuropeptides in the cranial circulation

    Detta är en avhandling från Anders Ottosson, Dept of Forensic Medicine, Sölvegatan 25, S-223 62 Lund, Sweden

    Författare :Anders Ottosson; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; neuropsychology; Neurology; Human - arteries - CGRP - SP - mast cells; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : The sensory neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP) are present in human cerebral, meningeal and temporal arteries, as are peptides associated with the sympathetic (neuropeptide Y, NPY) and parasympathetic (vasoactive intestinal peptide, VIP) nervous system. NPY is a vasoconstrictor in cerebral and meningeal arteries and potentiates noradrenaline (NA) as a vasoconstrictor in temporal arteries. LÄS MER

  2. 17. PACAP and airway regulation with special reference to smooth muscle and neutrophils

    Detta är en avhandling från Department of Otorhinolaryngology, Lund University

    Författare :Johan Kinhult; [2003]
    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. 18. Luminal Hypotonicity and Duodenal Functions An Experimental Study in the Rat

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Liselotte Pihl; Uppsala universitet.; [2007]
    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. 19. 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

    Detta är en avhandling från Stockholm : Karolinska Institutet, false

    Författare :Lena Bondesson Lundeberg; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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. 20. Purification, structure and function of bioactive peptides

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Medical Biochemistry and Biophysics

    Författare :Elo Eriste; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    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
