Using the tracer method and a mathematical model the paraplacental transport of free fatty acids (FFA) (via uterine fluid--yolk sac--fetus) has been investigated in 21 days pregnant rats. The results show that only 0.3 nmoles FFA per min pass into the fetus via this paraplacental route. This accounts for less than 1% of FFA transported from the maternal plasma across the placenta into the fetus (0.14 mumoles FFA per min). From these results we would like to draw the conclusion that the paraplacental transport of FFA to the rat fetus is of minor importance from the quantitative point of view.
采用示踪法和数学模型，对妊娠21天的大鼠经胎盘旁途径（通过子宫液 - 卵黄囊 - 胎儿）转运游离脂肪酸（FFA）的情况进行了研究。结果显示，经此胎盘旁途径每分钟仅有0.3纳摩尔FFA进入胎儿体内。这占从母体血浆经胎盘转运至胎儿的FFA总量（每分钟0.14微摩尔FFA）的不到1%。从这些结果我们可以得出结论，从定量角度来看，FFA经胎盘旁途径向大鼠胎儿的转运并不重要。
