    Sammanfattning : Crohns sjukdom är en kronisk inflammatorisk tarmsjukdom av okänd orsak. Det tidigaste tecknet på Crohns sjukdom är mikroskopiska sår i det s.k. follikelassocierade epitelet (FAE) som täcker ansamlingar av immunceller i tarmen. LÄS MER

  2. 2. Innervation and Functional Aspects of Neuropeptides in the Coronary Circulation

    Detta är en avhandling från Department of Internal Medcine, University Hospital of Lund

    Författare :Ole Saetrum Opgaard; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunohistochemistry.; mRNA; receptors; ET-B; ET-A; endothelin; substance P; calcitonin gene-related peptide; vasoactive intestinal peptide; acetylcholine; NPY; ATP; noradrenaline; nerves; sensory; parasympathetic; sympathetic; veins; Coronary; arteries; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : A network of perivascular nerve fibres was demonstrated in coronary arteries and veins from guinea-pig and man. Nerve fibres displaying immunoreactivity to neuropeptide Y (NPY) had a distribution pattern similar to those containing immunoreactivity to tyrosine hydroxylase. LÄS MER

  3. 3. Inhibitory neurotransmission in lower oesophagus

    Detta är en avhandling från Divison of Clinical Chemistry and Pharmacology

    Författare :Lars Ny; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; toxikologi; farmaci; Farmakologi; farmakognosi; toxicology; pharmacy; pharmacognosy; pituitary adenylate cyclase activating peptide; vasoactive intestinal peptide; Pharmacological sciences; oesophagus; nonadrenergic noncholinergic; nitric oxide; lower oesophageal sphincter; haem oxygenase; cyclic GMP; carbon monoxide; cyclic AMP;

    Sammanfattning : The inhibitory neuromuscular control of the human and cat lower oesophagus was investigated by morphological, functional, and biochemical methods. A supply of nerve fibres and myenteric cell bodies, containing nitric oxide synthase (NOS), haem oxygenase (HO)-2, vasoactive intestinal peptide (VIP), and pituitary adenylate cyclase activating peptide (PACAP) was observed.

  4. 4. The laryngeal mucosa and the superior laryngeal nerve of the rat an immunohistochemical and electron microscopic study

    Detta är en avhandling från Divison of Clinical Chemistry and Pharmacology

    Författare :Siw Domeij; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superior laryngeal nerve; paraganglia; substance P; calcitonin gene-related peptide; neuropeptide Y; vasoactive intestinal polypeptide; enkephalin; mast cells; electron microscopy; immunohistochemistry;

    Sammanfattning : Neuropeptides are present in nerve fibers of the upper and lower airways. Local release of these substances may be of importance for the pathophysiology of airway disorders and may play a role in responses to different stimuli. However, little is known about the distribution of neuropeptides in the larynx. LÄS MER

  5. 5. Aspects of aqueous humor dynamics : Studies in vivo and in vitro

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Samuelsson-Almén; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; Aqneous humor flow; intraocular pressure; adenylate cyclase; nonpigmented ciliary epithelium; pituitary adenylate cyclase-activating polypeptide; vasoactive intestinal polypeptide; dopamine; prostaglandin; Fysiologi och anatomi; MEDICINE Physiology and pharmacology; MEDICIN Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : The purpose of the present investigation was to study the effects of PGF2α-l-isopropylester, some neuropeptides, and pharmacological agents on aqueous humor dynamics and intraocular pressure (IOP) in vivo and on adenylate cyclase activity in the nonpigmented ciliary epithelium (NPE) in vitro.Pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) caused a dose-dependent increase in cAMP formation, indicating that the NPE contains receptors for PACAP and VIP coupled to adenylate cyclase activation.
