[Effect of chronic intrauterine hypoxia on purine compound metabolism in the erythrocytes of newborn infants in the early neonatal period]. / Vliianie khronicheskoi vnutriutrobnoi gipoksii na obmen purinovykh soedinenii v éritrotsitakh krovi novorozhdennykh v rannem neonatal'nom periode.

The content of purine compounds in red blood cells was measured and compared in 21 neonates with a history of chronic intrauterine hypoxia, depending on the condition at birth and the early period of adaptation. The content of purine compounds in whole blood was measured at the moment of birth and on days 1, 3 and 5 of life. It has been disclosed that the pattern of purine metabolism abnormality in funic red blood cells makes it possible to predict the course of the early period of adaptation. Changes in the content of hypoxanthine and inosine monophosphate appeared to be most remarkable.

[Indicators of lipid peroxidation and the level of essential microelements in healthy newborn infants and in those with a history of intrauterine hypotrophy]. / Pokazateli perekisnogo okisleniia lipidov i soderzhanie nezamenimykh mikroelementov u zdorovykh novorozhdennykh i pri vnutriutrobnoi gipotrofii.

The authors describe the results of studying lipid peroxidation, total antioxidant activity of plasma and the content of essential trace elements (iron, copper, zinc and selenium) in 35 healthy neonates and in 32 with intrauterine hypotrophy, grades I-III, at birth and the course of the early neonatal period. It has been found that in the neonates with a history of intrauterine hypotrophy, activation of lipid peroxidation resulted in the decrease of plasma antioxidant activity and in the changes of the concentration of essential trace elements.

[Contents of bioelements in blood of newborn infants with a history of chronic intrauterine hypoxia]. / Soderzhanie bioélementov v krovi novorozhdennykh, perenesshikh khronicheskuiu vnutriutrobnuiu gipoksiiu.

Emission analysis with the use of induced plasma was employed to measure the content of 9 bioelements (potassium, sodium, calcium, magnesium, phosphorus, iron, copper, zinc and selenium) in the blood serum of 82 neonates with a history of chronic intrauterine hypoxia and in 19 normal children at birth and in the course of early adaptation. It has been shown that the content of bioelements in the blood of normal neonates was marked by a number of characteristic features reflecting to a considerable degree the processes of metabolic adaptation of the children to the intrauterine life. The neonates with a history of hypoxia demonstrated the unbalance of bioelements most pronounced by day 3 of life. The treatment instituted did not make the content of bioelements in the neonates' blood return to normal.
