title: [Various aspects of transplacental blastomogenesis in rabbits].
abstract: Transplacental blastomogenic action of different carcinogenic agents (ethylnitrosourea--ENU), methylnitrosourea--MNU, dimethylbenzanthracene--DMBA, and benz(a)pyrene--BP) was studied in rabbits. As revealed, ENU had the greatest blastomogenic activity and an expressed neurotropic action. Relative tropism to different tissues characteristic of some carcinogenic agents during their action on adult organism was not always expressed in transplacental blastomogenesis, Study of the influence of different modifying factors (organospecific immunization, chronic irritation of the peripheral nerve, injection of the MNU) on the realization of transplacental blastomogenesis showed that their postnatal use stimulated mostly the appearance of the peripheral nerve timours in the offspring rabbits (MNU inhibited the development of tumours).
