THE PENETRATION OF Sr, Cs, Ru AND Fe THROUGH THE PLACENTAL AND MILK BARRIERS (in Russian)
9/, penetrate from the mother's body into the fetus through the placenta. It also gets into the offspring with milk during the period of lactation. All the elements which were tested enter the fetus in much lower quantities in ths early than in the later stages of pregnancy (in case of Cs, Ru, and Fe during the first 8 to 10 days, and within the first 166 days in case of Sr). The penetration of labelled atoms through the placental barrier is determined mainly by the intensity of growth and organogenesis of the fetus. Sr enters the fetus and milk from the maternal body also during the second pregnency, and when it is incorpoated for a comparatively long time prior to gestation. Considerable penetration of Sr and Fs through the placenta and milk barriers is associated with its lesser deposition in the organs and tissues of rats in comparison with the control. (auth)
