近年发现,在下丘脑和神经垂体以外的其他组织中也存在催产素,而且可能是由这些下丘脑-神经垂体以外的组织产生的。最近,在人类的卵巢,特别是黄体中,以及在某些非灵长类动物的卵巢黄体中也发现有催产素。有人提出,在母猪和母牛,催产素可能起着调控动情周期的作用,但卵巢催产素在人类的作用尚未弄清。为阐明在其它灵长类动物的卵巢中是否也有催产素,作者用成年雌性食蟹猴观察了猴黄体中是否含有免疫反应的催产素,其浓度在黄体期不同阶段有无差异,并与卵巢静脉血和外周血中催产素的水平进行了比较。
In recent years, oxytocin has also been found in tissues other than the hypothalamus and neurohypophysis, and may have been produced by tissues other than the hypothalamus-neurohypophysis. Oxytocin has recently been found in human ovaries, especially the corpus luteum, and in the ovary corpus luteum of some non-primate animals. It has been suggested that in sows and cows, oxytocin may play a role in regulating the estrous cycle, but the role of ovarian oxytocin in humans has not yet been clarified. In order to elucidate whether oxytocin is also present in the ovaries of other primates, the authors used adult female cynomolgus monkeys to observe whether or not the immunoreactive oxytocin was present in the monkey corpus luteum at various stages of the luteal phase with or without oxytocin The levels of oxytocin in venous and peripheral blood were compared.
