[Antiaggregant and antioxidant activity of estradiol and tamoxifen].
Tamoxifen did not influence the human platelet aggregation in vitro, while estradiol at a concentration of 10(-6) M inhibited the aggregation of human thrombocytes induced by ADP, serotonin + adrenaline, and adrenaline (epinephrine) by 14.7, 12.5, and 16.6%, respectively. Estradiol introduced in the range of effective concentrations from 10(-8) to 10(-4) M inhibited lipid peroxidation, while tamoxifen produced this effect only at a concentration of 10(-4) M. There was a correlation between the antiaggregant activity and antioxidant properties of estradiol.
