[Reactive hyperemia in vibration-induced disease].

The study of a blood flow in the forearm of patients with vibration disease has shown its significant lowering accompanied by an increase in vascular resistance in this region. Reactive hyperemia in the forearm vessels of these patients was diminished significantly, which shows decrease in the vasodilatation reserve induced by disturbances in functional activity of the endothelium. These disturbances are probably manifested in decrease of production of vasodilatation factors. Reactive hyperemia may be used to determine the endothelium dysfunctions caused by action of different pathogenic factors.
