Objective To study the contents, distr ibutions and cor relations of some macroelements in the or ganic tissues of healthy fetus and the maternal blood.
Methods The samples from fetal cerebrum, cerebellum, heart, liver, kidney, gas trocnemius, placenta and mother serum were digested with nitric acid and hydrogen peroxide solution in microw ave digestion system.Then the contents of so dium, potassium, calcium, mag nesium and phosphorus in those sample solutions were determined by inductively coupled plasma atomic emission spect rometry.
Results Amongthe five elements, sodium, potassium and phosphorus were abundant in all the above fetal tissues, calcium existed mainly in the fetal g astrocnemius and placenta, and magnesium existed mainly in the fetal heart, liverand kidney.Correlations between the contents of various elements in the same organ as well as the same element in different organs were observed in the study.
Conclusion The contents and distributions of macroelements in the healthy fetal organisms presented remar kable characteristics and correlations.
