[Histomorphological changes in newborn rat lung induced by maternal sugar intake].

Introduction: Respiratory conditions are the most common reason for admission to the neonatal unit for both term and premature newborns. It is known that nutritional imbalances during pregnancy affect the maturation and functional capacity of organs.

Objective: to describe the pulmonary histomorpholo- gy of newborn rats due to maternal sugar intake by light microscopy.

Reduction of all-trans-retinoic acid-induced teratogenesis in the rat by glycine administration.

Background: Prenatal rat embryo exposure to retinoids induces severe malformations in various organs; the most active and teratogenic metabolite is all-trans-retinoic acid (atRA). The mechanisms of this embryopathy are only partly known. In the present study, the influence of glycine on the teratogenicity of atRA was investigated.
