婴儿生下后的初几个月中,因母奶或牛奶中含铁量都很低,所以胎儿时期体内的储存铁是生后合成血红蛋白的重要来源。孕妇的血清铁是胎儿所需铁的唯一来源,胎儿和胎盘对孕妇血循环中的铁,具有特殊的摄取能力。我们开展放射免疫分析法测定血清铁蛋白,为测定新生儿体内储存铁的研究,开辟了一个新的途径。 The first few months after giving birth to an infant, the iron content in the mother’s milk or milk is very low, so the stored iron in the fetus during pregnancy is an important source of hemoglobin synthesis after birth. Serum iron for pregnant women is the only source of iron needed by the fetus, and fetuses and placentas have special uptake capacity for iron in the bloodstream of pregnant women. We carry out radioimmunoassay for determination of serum ferritin, which opens up a new way for the determination of iron storage in neonates.
