在发情周期或妊娠第11、13或15天，测量麻醉母猪子宫动脉和静脉血中雌二醇-17 β和雌酮的浓度。在相同的动物中测定子宫动脉血流量和子宫冲洗液中雌二醇-17 β和雌酮的量。在妊娠动物中，第11天和第13天雌二醇-17 β以及第15天雌酮的动脉和静脉浓度存在显著差异（P <0.05）。妊娠动物中两种类固醇的子宫含量始终高于非妊娠动物，在第13天达到峰值。子宫动脉血从妊娠第11天至第13天增加，然后在第15天下降（P <0.08）;在发情周期的相应日期，子宫血流量没有变化。
Concentrations of oestradiol-17 beta and oestrone were measured in the uterine arterial and venous blood of anaesthetized sows on Days 11, 13 or 15 of the oestrous cycle or of pregnancy. Uterine arterial blood flow and the amounts of oestradiol-17 beta and oestrone in uterine flushings were determined in the same animals. In pregnant animals arterial and venous concentrations were significantly different (P less than 0.05) for oestradiol-17 beta on Days 11 and 13 and for oestrone on Day 15. Uterine content of both steroids was consistently greater in pregnant than in non-pregnant animals with a peak on Day 13. Uterine arterial blood increased from Day 11 to 13 of pregnancy then declined (P less than 0.08) by Day 15; no change in uterine blood flow occurred on the corresponding days of the oestrous cycle.
