Popis: Oral contraceptives containing estrogens increases the incidence of thromboembolic events. In contrast, administration of 17beta-aminoestrogens prolonged blood clotting time (BCT) in rodents. We studied the effect of estradiol (E(2)), ethinylestradiol (EE) and pentolame on some screening hemostatic tests. BCT was evaluated 24, 48, 72 and 96 h post-treatment. Rats received subcutaneously (s.c.) for five consecutive days E(2) (0.1-1000 microg), EE (1-1000 microg), pentolame (0.1-1000 microg), or vehicle (propyleneglycol 0.3 ml). At 48 h post-treatment E(2) (1000 microg) diminished BCT (32%, P
