  1. 16. Neurohormonal Modulators in the Parathyroid Gland. Localization and regulation

    Detta är en avhandling från Department of Physiology and Neuroscience, Lund University

    Författare :Lena Luts; Lund University.; Lunds universitet.; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Receptor; In situ hybridization; Immunocytochemistry; Nitric Oxide Synthase; Endothelin; Neuropeptides; Chromogranin; Parathyroid adenoma; Parathyroid gland; Parathyroid hormone; mRNA; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : The occurrence and distribution of neurohormonal peptides, neuroendocrine markers and receptors in parathyroid nerve fibers and endocrine cells are described, using immunocytochemistry, in situ hybridization, image analysis and reverse transcriptase polymerase chain reaction. Immunocytochemical studies revealed that parathyroid glands of chicken, rat, guinea-pig, cat, dog and sheep contained adrenergic-, cholinergic-, and peptide-containing nerve fibers. LÄS MER

  2. 17. 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; Lund University.; Lunds universitet.; [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

  3. 18. 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; Lund University.; Lunds universitet.; [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

  4. 19. 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

  5. 20. Regulation of chloride secretion in HT29 cells studied by X-ray microanalysis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Wei Zhang; Uppsala universitet.; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anatomy; epithelium; chloride channel; HT29 cells; ion transport; volume; X-ray microanalysis; G-protein coupled receptors; α2-adrenoceptors; purinoceptors; muscarinic receptors; Anatomi; MEDICINE Morphology; cell biology; pathology Morphology Anatomy; MEDICIN Morfologi; cellbiologi; patologi Morfologi Anatomi; Human Anatomy; anatomi;

    Sammanfattning : Several aspects of Cl- secretion in epithelial cells were investigated. Methods to prepare cultured cellsfor X-ray microanalysis, in order to study volume-regulating chloride transport were evaluated. LÄS MER
