Effects of Ovulen-21, Demulen, Enovid-E and Ovral on zinc and copper levels in human plasma and endometrium during the menstrual cycle have been studied. Both plasma and endometrium copper levels were significantly elevated above the control values (P less than 0.001) in women taking oral contraceptives while the zinc levels remained reasonable constant.
研究了Ovulen - 21、Demulen、Enovid - E和Ovral对月经周期中人体血浆和子宫内膜锌、铜水平的影响。服用口服避孕药的女性,其血浆和子宫内膜中的铜水平均显著高于对照值(P小于0.001),而锌水平则保持相对稳定。
