Neuropeptide Y (NPY), noradrenaline (NA) and ATP are cotransmitters of the sympathetic nervous system and exert vasocontractile effects. The aim of this study was to determine the role of these sympathetic co-transmitters in human hypertension. Subcutaneous vessels from 12 patients with essential hypertention and 12 matched controls were studiedin vitro.(More)
Vascular smooth muscle contractile responses to neuropeptide Y, α,ß-methyleneATP and noradrenaline were studied in circular segments of isolated vessels with intact endotheliumin vitro from 12 patients with diabetes mellitus type 2 (NIDDM) and 12 control subjects. The dilatory effect of acetylcholine was used to test the function of the endothelium.(More)
Diabetes is commonly complicated by thrombosis and atherosclerosis. In humans, diabetes mellitus has been associated with a decreased synthesis of prostacyclin, which could partly explain the prothrombotic state. Experimental diabetes has been diverging in this aspect, and endothelial damage has been proposed to be an early event. To analyse whether the(More)
