RESUMO

A suboptimal intrauterine environment has a number of deleterious effects on fetal development and postpartum health outcomes. Epidemiological studies on several human populations have linked socioeconomic status and low birth weight to an increased incidence of diseases such as hypertension, diabetes, obesity and cardiovascular disease. A growing number of experimental studies in a variety of animal models demonstrate that maternal stressors, such as nutrition and reduced uterine perfusion, affect the intrauterine milieu and result in increased blood pressure in offspring. Several mechanisms appear to contribute to hypertension, including vascular dysfunction and increased peripheral resistance, altered cardio-renal structure and alterations in cardio-renal function. Although many studies have characterized models of developmentally generated hypertension, few have begun to seek therapeutic modalities to ameliorate its incidence. This review discusses recent work that refines hypotheses linking a suboptimal intrauterine environment to cardiovascular and renal phenotypes that have increased susceptibility to cardiovascular disease and hypertension.

RESUMO

Histological investigations were conducted in 75 embryos and fetuses with 10- and 20-days term of embryogenesis obtained from 15 pregnant rats with experimental renal hypertension. It was established employing general biological, enzyme histochemical, impregnation and morphometric methods that short-time hypertension of the maternal [correction of material] body produces delay of growth, development and differentiation of nerve cells and their fibers of the respiratory organs. At the same time by the end of pregnancy separate nerve elements were detected with pronounced signs of high organization and differentiation. This should, apparently, be evaluated as a manifestation of compensatory-adaptative properties of the peripheral nervous system to inadequate conditions developing in the process of embryogenesis.
