The transmission of S/sup 35/ mercamin from the mother to the fetus was studied. Experiments were staged on 50 white female rats, of which 12 were nongravid, 13 had a 13-day pregnancy, and 25 had a 21-day pregnancy. Labeled mercamin was introduced intraperitonealy (20 mc per animal). The S/sup 35/ activity in the organs of the mother and fetuses (21st intrauterine day) was assessed 15 minutes after the introduction of the preparation. It was established that the S/sup 35/ distribution in the organs of gravid and nongravid animals is more or less similar. Toward the end of pregnancy the accumulation of S/sup 35/ in the gravid uterus intensifies. The placenta accumulated S/sup 35/ to a lesser degree than the uterus and checked its transition from the mother to the fetus. The S/sup 35/ accumulation in the fetal organs was several times lesser than in the corresponding maternal organs. (auth)
