Corpora lutea from opossums late in pregnancy were examined by immunohistochemistry for the presence of oxytocin. Oxytocin-immunoreactivity was observed in all corpora lutea examined but not elsewhere in ovarian tissue. The immunoreactive staining observed was confined primarily to the perinuclear cytoplasm of reactive luteal cells. Not all luteal cells showed oxytocin-immunoreactivity. The immunohistochemical localization of oxytocin in the pregnant opossum corpus luteum demonstrates for the first time this peptide in a metatherian ovary. Its presence in this primitive species suggests that oxytocin has a fundamental role in the physiology of the mammalian ovary.
通过免疫组织化学方法对妊娠后期负鼠的黄体进行检查，以确定是否存在催产素。在所检查的所有黄体中均观察到催产素免疫反应性，但在卵巢组织的其他部位未观察到。观察到的免疫反应性染色主要局限于反应性黄体细胞的核周细胞质。并非所有黄体细胞都显示出催产素免疫反应性。催产素在妊娠负鼠黄体中的免疫组织化学定位首次在有袋类动物卵巢中证实了这种肽的存在。它在这种原始物种中的存在表明，催产素在哺乳动物卵巢生理学中具有重要作用。
