Invariability of blood viscosity after cold testing in patients suffering for Raynaud's disease. 1980

P Pola, and L Savi, and A Dal Lago, and R Flore, and J Shami

The paper presents a study on the behaviour of blood and plasma viscosity before and after vasospastic crises induced by cold testing. The study was performed in 10 subjects with Raynaud's disease and in control group of 10 normal subjects. The data obtained do not suggest correlation between variation in viscosity and angiospastic crises.

UI MeSH Term Description Entries
D010991 Plethysmography Recording of change in the size of a part as modified by the circulation in it. Plethysmographies
D011928 Raynaud Disease An idiopathic vascular disorder characterized by bilateral Raynaud phenomenon, the abrupt onset of digital paleness or CYANOSIS in response to cold exposure or stress. Cold Fingers, Hereditary,Raynaud Phenomenon,Raynaud's Disease,Raynauds Disease
D001783 Blood Flow Velocity A value equal to the total volume flow divided by the cross-sectional area of the vascular bed. Blood Flow Velocities,Flow Velocities, Blood,Flow Velocity, Blood,Velocities, Blood Flow,Velocity, Blood Flow
D001809 Blood Viscosity The internal resistance of the BLOOD to shear forces. The in vitro measure of whole blood viscosity is of limited clinical utility because it bears little relationship to the actual viscosity within the circulation, but an increase in the viscosity of circulating blood can contribute to morbidity in patients suffering from disorders such as SICKLE CELL ANEMIA and POLYCYTHEMIA. Blood Viscosities,Viscosities, Blood,Viscosity, Blood
D003080 Cold Temperature An absence of warmth or heat or a temperature notably below an accustomed norm. Cold,Cold Temperatures,Temperature, Cold,Temperatures, Cold
D005340 Fibrinogen Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
