The concentrations of cytoplasmic oestrogen and progesterone receptors were measured in rat myometrium during the post partum involution of the uterus. The concentration of the oestrogen receptor declined within 24 h post partum to about 20% of the value at delivery. A slight rise in the concentration occurred during the subsequent 24 h. The concentration of the progesterone receptor remained nearly constant the first day after delivery. Thereafter it decreased just as the concentration of the oestrogen receptor had fallen one day before. The results suggest that the post partum levels of oestrogen and progesterone receptors are regulated by the same mechanisms as those known for the non-pregnant state.
在大鼠子宫产后复旧过程中,测定了子宫肌层细胞质中雌激素和孕激素受体的浓度。产后24小时内,雌激素受体浓度降至分娩时值的约20%。在随后的24小时内浓度略有上升。孕激素受体浓度在分娩后的第一天几乎保持不变。此后,它如同一天前雌激素受体浓度下降那样降低。结果表明,产后雌激素和孕激素受体水平与非妊娠状态下已知的调节机制相同。
