Abstract
The enzymatic activities of human umbilical vessels from normal term pregnancies were studied by histochemical methods. The results obtained suggest that oxidative phosphorylation is of little importance, whereas pentose cycle and anaerobic glycolysis are probably the most important sources of energy in the umbilical vessels. The presence of leucine aminopeptidase activity in the venous endothelium probably represents a defensive mechanism inactivating oxytocin.
摘要
采用组织化学方法研究了足月正常妊娠的人脐血管的酶活性。所得结果表明，氧化磷酸化作用不太重要，而戊糖循环和无氧糖酵解可能是脐血管中最重要的能量来源。静脉内皮中亮氨酸氨肽酶活性的存在可能代表了一种使催产素失活的防御机制。
