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

Abstract

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<0.05) on the distribution of Na(123)I in the P (from 69.64 to 86.13) and BC (from 30.36 to 13.87) and altered the fixation of the Na(123)I in IF-P and in IF-BC.
