    Abstract:
    The effect of flaxseed extract (FSE) containing 42% secoisolariciresinol diglucoside on the blood plasma estradiol level and theological properties of blood in female Wistar rats after ovariectomy was investigated by measuring hematocrit, fibrinogen concentration, platelet aggregation and deformability, and the whole blood and plasma viscosity. Bilateral ovariectomy in rats led (in comparison to sham-operated animals) to a decrease in the estrogen level to 59% and produced a 5-9% increase in the whole blood viscosity, which was caused by impairment of the erythrocyte deformability and aggregation. The efficacy of oxygen transport to tissues was decreased by 4-7%. The treatment of ovariectomized rats with FSE (peroral administration at a daily dose of 40 mg/kg for 14 days) reduced the whole blood viscosity by 4-11% and increased the coefficient of oxygen transport to tissues by 5-11%, but did not restore the estrogen level. Thus, the hemorheological effect of FSE reduces to the improvement of microrheological parameters (decrease in erythrocyte aggregation and increase in their deformability) without the modification ofmacrorheological parameters (hematocrit, plasma viscosity and fibrinogen level).
