[Chromogenic and immunological determination of antithrombin III and of antiplasmin in subjects under treatment with oral hormonal contraceptives].

We have effectuated a chromogenic and immunologic determination of alpha 2-At III and antiplasmin in plasma into three groups of patients. The 1st group is constituted of 93 subjects which never take oral hormone contraceptives. The 2nd group is constituted of 56 subjects who are taking oral hormone contraceptives. The 3rd group is constituted of 55 subjects in pregnancy (VI-VIII months). The results show a light difference, in the immunologic assay, between I in equilibrium or formed of II and I in equilibrium or formed of III, but there is not a significant difference in the chromogenic determination. Data have not evidenced significant variations in the antiplasmin too, except for the group of subjects in pregnancy.
