Sammanfattning : Impaired endothelium-dependent vasodilation (EDV) is associated with atherosclerotic cardiovascular disease as well as several of its risk factors. The aim of the present thesis was to investigate how lipids influence EDV in the vascular bed of the human forearm. LÄS MER
Sammanfattning : This thesis examines the microvascular inflammatory response in the skin. The microvascular response includes vasodilatation and plasma exudation. In the first three studies, the combined response was measured in guinea pig skin with a technique based on detection of radiolabelled protein. LÄS MER
Sammanfattning : Extracellular nucleotides induce dilatation and constriction of blood vessels by activation of P2 receptors. In this thesis the vasomotor effects of P2 receptor activation were studied in the rat mesenteric artery, and their changes in congestive heart failure (CHF) were evaluated using in vitro pharmacology, electrophysiology and competitive RT-PCR.

Sammanfattning : Abstract The aims of the present thesis were to examine neuropeptide Y (NPY) responses in different human and guinea pig vascular beds and in cultured human vascular smooth muscle cells (VSMC) and to characterize, with different NPY agonists and the specific NPY Y1 receptor antagonist (BIBP3226), the NPY receptors involved. NPY-induced strong and potent contractions in human cerebral and subcutaneous arteries and in guinea pig basilar arteries. LÄS MER
5. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function
Sammanfattning : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. LÄS MER
