[Sigetin treatment of the developmental disorders induced in rabbit prenatal ontogeny by curtailment of the uteroplacental blood circulation].

About 40 per cent of the uterine preplacental vessels were ligated in rabbits on the 11th or 18th days of gestation. Some of the female rabbits operated upon were given 5 mg of intravenous sigetin twice a day till the end of pregnancy. Investigation of the progeny development, the ability of learning at an age of about 6 months, in particular, showed a somewhat better development and ability of learning in the offsprings of female rabbits receiving sigetin.
