Sows and ewes were killed at various times during gestation. Minced uterine samples were incubated for 3 h with [6,7-3H]oestrone sulphate or [2,4,6,7-3H]oestrone, respectively. Contrasting patterns of enzyme activities were found in the sow and ewe. In the sow, endometrial sulphotransferase activity declined after Day 30 of gestation, while in the ewe, sulphation gradually increased after Day 16. The inverse was found for the activity of oestrogen sulphatase during pregnancy.
母猪和母羊在妊娠期的不同时间被宰杀。将切碎的子宫样本分别与[6,7-³H]硫酸雌酮或[2,4,6,7-³H]雌酮一起孵育3小时。在母猪和母羊中发现了不同的酶活性模式。在母猪中，妊娠30天后子宫内膜硫酸转移酶活性下降，而在母羊中，妊娠16天后硫酸化作用逐渐增加。在怀孕期间，雌激素硫酸酯酶的活性情况则相反。
