Ginkgo biloba extract alters the binding of the sodium [123I] iodide (Na123I) on blood constituents.

We evaluated the in vitro effect of an aqueous extract of Ginkgo biloba (EGb) on the distribution in blood cells (BC) and plasma (P) and on the binding of Na(123)I to the blood constituents using precipitation with trichloroacetic acid. The radioactivity percentages insoluble (SF) and insoluble fraction (IF) of blood constituents were determined. The EGb interfered (p<0.

Physiological (osmotic fragility) and morphological effects on red blood cells: action of phytic acid and stannous fluoride.

Phytic acid occurs in foods derived from plants. We have investigated the possibility that phytic acid and stannous fluoride are capable of altering the physiological properties (osmotic fragility) and morphological properties of red blood cells (RBC). Osmotic fragility was unchanged by the presence of phytic acid and stannous fluoride in the studied concentrations, but RBC morphology was modified in the presence of the studied substances.
