Serial frozen sections of human term placentae were examined by quantitative morphology and, after extraction, by a radioimmunoassay for human placental lactogen (HPL). The total quantity of HPL in the placenta was estimated as 720 mg. The amount of HPL was related to the amount of trophoblast in any area, but otherwise did not vary in different parts of the placenta. A semi-logarithmic relationship was observed between the amount of HPL and the percentage trophoblast in a section. It is suggested that the amount of HPL in a given area of the placenta is related to the blood-flow in that area.
通过定量形态学方法对足月人类胎盘的连续冰冻切片进行检查，并在提取后通过放射免疫分析法检测人胎盘催乳素（HPL）。胎盘内HPL的总量估计为720毫克。HPL的含量与任何区域的滋养层数量有关，但在胎盘的不同部位并无其他差异。在切片中观察到HPL含量与滋养层百分比之间呈半对数关系。有人认为，胎盘特定区域内HPL的含量与该区域的血流量有关。
