  2. 1. Non-invasive measurement of skeletal muscle blood flow using by photoplethysmography. Experimental studies on the human leg

    Author : Qiuxia Zhang; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photoplethysmography; skeletal muscle blood flow; perfusion pressure; intramuscular pressure; venous obstruction; muscle exercise; non-invasive; limb elevation; vibration exposure; hyperaemia; foot pump.;

    Abstract : The purpose of this thesis was to validate a new non-invasive photoplethysmography (PPG) method for measuring relative changes in local muscle blood flow (MBF) in the human leg. Experimental conditions expected to impede or increase local MBF were used to test responsiveness of the PPG. READ MORE

  4. 2. A study on the vascular effects of prostaglandin F2α[ and latanaprost in the eye with special reference to the surface hyperaemia after topical administration

    Author : Maria Astin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Prostaglandin F2a; Prostaglandin F2a-isopropyl ester; latanoprost; latanoprost acid; ocularhyperaemia; blood flow; sensory nerves; veins; arteries; nitric oxide; substance P; CGRP; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Pharmacognosy; farmakognosi;

    Abstract : The ocular hypotensive effect of topically applied prostaglandins is usually accompanied byconjunctival hyperaemia and irritation. The purpose of the present study was to investigate thepharmacological mechanism of the ocular surface hyperaemia induced by topically appliedprostaglandins, particularly prostaglandin F2α (PGF2α) and its synthetic analogue latanoprost, aselective FP prostanoid receptor agonist.

  5. 3. Ventricular fibrillation and defibrillation in patients with implantable cardioverter defibrillators

    Author : Mikael Runsiö; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ventricular fibrillation; defibrilla~ion; implantable cardioverter defibrillator; haemodynamic; metabolism; hyperaemia; ischaemia; myocardial injury; histamine; neuropeptide 1: noradrenaline; endothelin; histamine; positron emission tomography.;

    Abstract : Since the introduction of the implantable cardioverter defibrillator for humans with malignant ventricular arrhythmias in 1980, over 50, 000 patients world wide have received this device. The implantation procedure is simple and resembles the implantation of an ordinary pacemaker. READ MORE

  6. 4. Studies on sitting pressure and buttock microcirculation : aiming at developing an alarm in the prevention of pressure ulcers in patients with spinal cord injuries

    Author : Johan Thorfinn; Disa Lidman; Folke Sjöberg; Henry Svensson; Linköpings universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Blood supply; Buttocks; Hyperemia; Ischemia; Laser-Doppler flowmetry; Microcirculation; Posture physiology; Pressure; Skin blood supply; Medicine; Medicin;

    Abstract : Pressure ulcers in patients with spinal cord injuries are a major problem, the prevalence in this group being reported as high as 20 – 30 percent. Most pressure ulcers develop around the pelvic girdle, and the key-contributing factor in the development of pressure ulcers is ischaemia due to longstanding pressure. READ MORE

  7. 5. Release and effects of calcitonin gene-related peptide in myocardial ischaemia

    Author : Göran Källner; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : A proportion of sensory C-fibres is characterized by sensitivity to the pungent agent in hot peppers, capsaicin. Upon stimulation by capsaicin, co-stored peptides including calcitonin gene-related peptide (CGRP), are released from the peripheral terminals of these fibres. READ MORE
