An attempt has been made to show that the increase in enzyme activities in sera of pregnant women found with glucose-6-phosphate and adenosine 5'-monophosphate as substrates (described as glucose-6-phosphatase and 5'-nucleotidase) was due to the increase in alkaline phosphatase. The three enzyme activities has pH optima and heat stability characteristics of alkaline phosphatase. The response to the action of inhibitors and activators was typical for alkaline phosphatase. There was an identical increase in all three enzyme activities during pregnancy. As a control similar investigations were made with liver and placental tissue extracts.
有人试图证明，以葡萄糖-6-磷酸和5'-磷酸腺苷为底物（称为葡萄糖-6-磷酸酶和5'-核苷酸酶）时，孕妇血清中酶活性的增加是由于碱性磷酸酶增加所致。这三种酶活性具有碱性磷酸酶的最适pH值和热稳定性特征。对抑制剂和激活剂作用的反应是碱性磷酸酶的典型反应。孕期所有三种酶活性均有相同程度的增加。作为对照，对肝脏和胎盘组织提取物进行了类似研究。
