  • Title: [The effect of unfavorable environmental factors on the mother-fetus system].
    Author: Serova LV.
    Journal: Usp Fiziol Nauk; 1999; 30(3):62-72. PubMed ID: 10512012.
    Abstract:
    The paper provides a generalization of data and the results of own experiments with Wistar rats in the conditions of hypokinesia, immobilization, water deprivation, hypergravity, weightlessness and other factors affecting mother and fetus as a system. It gives a comparison of reactivity of pregnant and non-pregnant animals under stress, and also of the effects of unfavorable impacts sustained during various phases of ontogenesis: in pubertation period, directly before pregnancy and during various phases of pregnancy. It demonstrated that exposition of pregnant animals to unfavorable conditions is accompanied by significant stress of the compensatory-adaptive possibilities of mother aiming to support of homeostasis of the developing fetus. Clear changes develop in fetus only in case the adaptive possibilities of mother turn out inadequate or when the developing organs of fetus become active components of adaptive reaction of mother-fetus system and compensate for functional inadequacy of some mother's organ. The paper discusses the problem of individual features of resistivity and reactivity.
