The thromboplastin activity in blood monocytes from 13 women on oral contraceptives and from a reference group of 20 women not on oral contraceptives has been compared. The thromboplastin activity in endotoxin-stimulated monocytes from the oral contraceptive (OC) users was on average 54% of the activity in the reference group (p less than 0.05). The thromboplastin activity in unstimulated monocytes was also lower in the OC group than in the reference group although not statistically significant. Factor VII was significantly higher (p less than 0.05) in the OC group, whereas no difference was observed in fibrinogen and factor V levels.
对13名服用口服避孕药的女性和20名未服用口服避孕药的女性对照组的血液单核细胞中的凝血活酶活性进行了比较。口服避孕药（OC）使用者的内毒素刺激单核细胞中的凝血活酶活性平均为对照组活性的54%（p<0.05）。OC组未受刺激的单核细胞中的凝血活酶活性也低于对照组，尽管无统计学意义。OC组的凝血因子VII显著更高（p<0.05），而纤维蛋白原和凝血因子V水平未观察到差异。
