Effect of a diet rich in linseed oil on complex viscosity and blood pressure in spontaneously hypertensive rats -SHR-
Abstract
The influence of a diet rich in linseed oil (10 % in weight) with a content of 61.2 % of Alphalinolenic fatty acid on blood pressure and complex blood viscosity was investigated in spontaneously hypertensive rats. A decrease in blood pressure by 59 mm Hg was found compared to the age-matched, untreated control group. The viscous (Eta') and elastic (Eta") components of viscosity were also reduced at various shear rates (Gamma). The same applies to the aggregation index, which is a measure of the aggregation tendency of red blood cells (RBC). Of course, the effects on blood viscosity cannot explain the observed degree of blood-pressurelowering. Nevertheless, a decrease in the viscosity can improve the flow conditions in the microcirculation, which may lead to a better oxygen supply.
