Mammotrophic activity was present in rat amniotic fluid collected on days 13, 15 and 19 of pregnancy. The mammotrophic activity in the fluid was equivalent to that in the maternal serum on day 15, but is was lower on day 19. The effect of tha amniotic fluid was similar to that of human placental lactogen on the rat mammary gland in vitro. The prolactin concentration in the amniotic fluid was low (approximately 1 ng/ml).
在妊娠第13、15和19天收集的大鼠羊水中存在促乳腺生长活性。羊水的促乳腺生长活性在第15天与母体血清中的相当，但在第19天较低。羊水对大鼠乳腺的作用在体外与人胎盘催乳素的作用相似。羊水中催乳素浓度较低（约1纳克/毫升）。
