[Content of components of the renin-angiotensin-aldosterone system of blood plasma of healthy children in the early neonatal period].

Abstract

The dynamics of the renin and angiotensin converting ferment activity and of the aldosterone concentration in the plasma of blood by healthy newborn full-term in the first week of the life after the birth was determined. The normative values of the studied indexes were obtained. The researches have shown the considerable functional tension of the renin-angiotensin-aldosterone system, that has a very important signification for optimal course of adaptation and anabolic processes by the children at the very beginning of the postnatal development.
