Reactive Hyperemia in Human Forearm Vessels
Background The role of nitric oxide (NO) in reactive hyperemia (RH) is not well known. We investigated whether NO plays a role in RH in human forearm vessels by examining the effects of N0-monomethyl-L-arginine (L-NMMA), a blocker of NO synthesis, on reactive hyperemic flow. Methods and Results Forearm blood flow (FBF) was measured by strain-gauge plethysmography with a venous occlusion techniq...
متن کاملPerineural capsaicin treatment attenuates reactive hyperaemia in the rat skin.
The neural mechanisms of reactive cutaneous hyperaemia were studied by using a novel experimental approach: the simultaneous measurement of cutaneous blood flow by laser-Doppler flowmetry in adjacent innervated and chemodenervated skin regions of the rat hindpaw served by the same artery. Transient occlusion of the femoral artery (0.5-6 min) resulted in reactive hyperaemia that was greatly redu...
متن کاملThe effect of reactive artery hyperaemia on the radial strain of the brachial artery: Definition of optimum cuff position
Instruction: Measurement of brachial artery diameter variation by ultrasound methods has commonly been used to test the endothelial function. It is known that the artery diameter is increased by flow stimulation. Therefore in the present study, the effect of external obstruction, as flow stimulation, on the radial strain of the brachial artery was assessed. Also the biomechanical behavior of...
متن کاملFlorid reactive periostitis of the forearm bones in a child.
Florid reactive periostitis is a pronounced periosteal reaction, usually affecting the hands and feet, for which there is no obvious cause. It is rare in children and in long bones. We report an unusual case of florid reactive periostitis in a ten-year-old girl that involved both bones of the forearm. The lesion resolved over a period of one year, leaving a residual exostosis. She developed a p...
متن کاملReactive hyperemia increases forearm vein area.
PURPOSE To determine the effect of reactive hyperemia on human forearm vein area. METHODS After obtaining ethics approval and informed consent, an automatic tourniquet was applied to the forearms of 20 healthy subjects for one, two, and three minutes, at pressures of 25 mmHg, 200 mmHg, then 25 mmHg. A blinded radiographer measured the cross-sectional area of the cephalic vein at the wrist usi...
