  1. 1. Short- and long-term cardiovascular and behavioural effects of oxytocin : mechanisms involved and influence of female steroid hormones

    Författare :Maria Petersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :oxytocin; nociceptive thresholds; naloxone; blood pressure; heart rate; spontaneous motor activity; oestrous cycle; ovariectomy; oestradiol; progesterone; weight gain; clonidine; locus coeruleus; alpha 2-adrenoreceptor; cholecystokinin; insulin; gastrin; corticosterone; ACTH; rat;

    Sammanfattning : The aim of the present thesis was to investigate short- and long-term cardiovascular and behavioural effects of oxytocin. In addition, the influence of female steroid hormones as well as possible mechanisms behind the oxytocin induced effects were investigated. LÄS MER

  3. 2. On the function endogenous pain controlling systems in healthy subjects and patients with peripheral or central neuropathic pain

    Författare :Birgitta Tuveson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Painful peripheral neuropathy; Central post-stroke pain; Dynamic mechanical allodynia; Endogenous pain modulation; Heterotopic noxious conditioning stimulation; Quantitative sensory testing; Ondansetron;

    Sammanfattning : Introduction and aim: Activity in the nociceptive system is modulated by descending inhibitory and facilitatory supraspinal endogenous control. Altered balance between inhibition and facilitation has been suggested to at least partly explain the maintenance of some persistent pain conditions. LÄS MER

  4. 3. Pain analysis : A study in patients with chronic low back pain or fibromyalgia

    Författare :John Sörensen; Alf Udén; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Chronic low back pain (CLBP} and fibromyalgia (FM} are two common chronic pain conditions in which the pain processing mechanisms are not well understood. To identify the types of pain, we used different intravenous {t.v. LÄS MER

  5. 4. Neuropathic pain : somatosensory functions related to spontaneous ongoing pain, mechanical allodynia and pain relief

    Författare :Åsa Landerholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Peripheral neuropathic pain; Central post stroke pain; Dynamic mechanical allodynia; Static mechanical allodynia; Dysesthesia; Quantitative sensory testing; Spinal cord stimulation.;

    Sammanfattning : Introduction and aim: Patients with neuropathic pain suffer from spontaneous ongoing pain and from abnormal stimulus-evoked pain, e.g., allodynia. LÄS MER

  7. 5. Changes in sensory systems during aging : an experimental study in the rat

    Författare :Esbjörn Bergman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :aging; behavior; primary sensory neuron; dorsal root ganglion; mystacial pad; sensory nerve ending; axon dystrophy; neuropeptides; B4; RT97; CTB; neurotrophins; trk; p75NTR; GFR[alpha]; RET; protein; mRNA;

    Sammanfattning : Aging is associated with sensorimotor disturbances, including increased proprioceptive thresholds. The present study aimed to clarify the occurrence of structural and biochemical alterations in sensory systems of behaviorally characterized aged rats. LÄS MER
