Abstract
With the method of pH-Stat the adenosinedeaminase-, adenosine-5'-monophosphate deaminase-, cytidine-5'-monophosphate deaminase activities are determined in the nucleus-, mitochondrial-, microsomalfractions and in the cytoplasmatic fractions of the human termplacental and amniotic tissues. The desaminase activities were higher in the amniotic fractions. The possible importance of the adenosinedesaminase and adenosine-5'-monophosphate desaminase for the fetal-placental blood circulation is discussed.
摘要
采用pH值测定法，测定了足月人胎盘和羊膜组织的细胞核、线粒体、微粒体及细胞质部分中腺苷脱氨酶、5'-单磷酸腺苷脱氨酶、5'-单磷酸胞苷脱氨酶的活性。羊膜部分的脱氨酶活性较高。文中讨论了腺苷脱氨酶和5'-单磷酸腺苷脱氨酶对胎儿-胎盘血液循环的可能重要性。
