The aim of the study was to assess endothelial function, measured by flow-mediated dilation (FMD), in an inactive extremity (leg) and chronically active extremity (arm) within one subject. Eleven male spinal cord-injured (SCI) individuals and eleven male controls (C) were included. Echo Doppler measurements were performed to measure FMD responses after 10 and 5 min of arterial occlusion of the ...

The authors investigated the effect of repeated inunction with 2 per cent glyceryl trinitrate in lanolin on the blood flow and skin temperature of the extremities in 14 cases of Raynaud's disease and in 8 cases in which Raynaud's phenomenon was associated with such vascular diseases as acrosclerosis (3 cases), chronic occlusive disease of the arteries (3 cases), occupational disease of the arte...

1254 May 2014 H micro-ultrasound is a new, preclinical technology that utilizes higher frequencies compared to conventional ultrasound. During a feasibility trial using high-frequency micro-ultrasound for vascular access in children, radial artery spasm in an 8-month-old male child was uniquely documented with a 50-MHz probe. The intraluminal diameter before attempted cannulation was 2.1 mm (fi...

BACKGROUND Treatment of brown recluse spider bites remains controversial; there are multiple options but little evidence of their effectiveness. METHODS Over a 5-year period, family physicians enrolled consecutive patients with suspected brown recluse spider bites. Usual care was provided based on physician preferences. Topical nitroglycerine patches and vitamin C tablets were provided at no ...

Vascular dysfunction in chronic renal failure may be linked to reduced nitric oxide (NO) bioactivity and increased circulating concentrations of the endogenous NO synthase inhibitor asymmetrical dimethyl L-arginine (ADMA). The association between ADMA and basal endothelial NO release and endothelium-dependent vasodilation in resistance arteries of chronic renal failure patients is unknown. Fore...

The purpose of this study was to evaluate vascular function and activity of Rho-associated kinases (ROCKs) in patients with primary aldosteronism. Vascular function, including flow-mediated vasodilation (FMD) and nitroglycerine-induced vasodilation, and ROCK activity in peripheral leukocytes were evaluated in 21 patients with aldosterone-producing adenoma (APA), 23 patients with idiopathic hype...

The aim of this study was to evaluate the effect of inhaled nitric oxide on the central (pulmonary) haemodynamics in the patients undergoing surgery for mitral valve or combined defects, with special focus on the period after weaning of the patient from the extracorporeal circulation (ECC). A total of 50 patients were randomly allocated to two groups. One had nitric oxide added to the inhalatio...
