  1. 1. Central pain after spinal cord injury : experimental studies with special emphasis on pharmacological treatment

    Författare :Wei Yu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :allodynia; central pain; ischemia; spinal cord injury; intrathecal; opioid; opioid receptors; selective opioid agonists; selective opioid antagonists; tolerance; dependence; clonidine; bovine chromaffin cells; encapsulation; resiniferatoxin;

    Sammanfattning : Injuries and dysfunctions of the central nervous system can cause central pain which, according to clinical experience, is often refractory to conventional treatments. The present thesis consists of experimental studies on the mechanisms and treatments of central pain using a well-established animal model of central pain after spinal cord injury. LÄS MER

  2. 2. Vasodilator actions of EDHF and anandamide

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vanilloid receptors; afferent neurons; anandamide; cannabinoids; potassium channels; hyperpolarization; vasodilation; Vascular endothelium; arteries; airways; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : Vasodilator responses to endothelium-derived hyperpolarizing factor (EDHF) and anandamide in isolated arteries were investigated. A combination of the potassium channel blockers charybdotoxin and apamin inhibits EDHF-mediated relaxations. LÄS MER

  3. 3. Sensory neuropeptides and nitric oxide in nasal vascular regulation

    Författare :Johan Rinder; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Sensory nerves; neuropeptides; nasal mucosa; nitric oxide; vascular regulation; acoustic rhinometry; NK1-receptors; CGRP-receptors; vanilloid receptors; capsaicin; lactic acid; exercise; a-adrenoceptor agonists; pig; human.;

    Sammanfattning : The role of sensory neuropeptides and nitric oxide in vascular regulation was investigated in the pig nasal mucosa in vivo using arterial blood flow measurements and acoustic rhinometry for analysis of capacitance function. Moreover, the effects of heavy physical exercise, a-adrenoceptor agonists, nitric oxide synthase (NOS) inhibition, L-arginine, nitric oxide (NO) gas, histamine and capsaicin on nasal cavity NO levels and nasal cavity volume, were investigated in healthy subjects.
