Nucleic Acids, Peptides, and Proteins,f corticosteroids to pregnant rats or to neonates adversely affects the early differentiation of the adrenal cortex (4). However, the structural damages occurring in the fetal adrenal and ovary by the transplacental effect of estrogens or corticoids have not been described.

Hyperasymptotic Perturbation TheoryThese host differences offer opportunity for variability in reaction to a noxious drug. The life span — from conception to old age — is divided biologically and on other grounds into quite different periods rather clearly separated from each other. This presents another host basis for variability to a drug’s effects.

https://doi.org/10.1007/978-1-4684-2193-4When administered to vertebrate embryos at a particular stage of development and at doses which allow survival of the embryo, nitrogen mustard produces a very similar type of malformation in different animal species. Limb malformations were obtained in amphibians, mammals and birds (1,2).

Vincent E. Rubatzky,Mas Yamaguchiot the only mode of differentiation. Aside from building new organs, the fetus must also organize new metabolic functions, and for this purpose, new enzymes have to be induced. These aspects of development may be considered as a metabolic differentiation and one may speculate about the effects of dr
