[Purine base metabolism in the mother-placenta-fetus system in experimental hypoxia]

In acute deficiency of oxygen inhibition of purine bases turnover as well as degradation of their high molecular precursors occurred in the system mother-placenta-fetus. Acute hypoxia was accompanied by distinct increase in content of adenine, xanthine + + guanine and uric acid in blood of pregnant rats, in placenta and blood of newborn animals. Long-term effect of hypoxia resulted in adaptation of purine metabolism. In this case production of adenosine and adenosine monophosphate was activated.
