[Intensity of the metabolism of separate brain phospholipid fractions in hyperphenylalaninemia].

Effect of acute and chronic forms of hyperphenylalaninemia on intensity of metabolism and content of some phospholipid fractions was studied in brain of growing rats. Acute form of hyperphenylalaninemia caused a decrease in metabolic activity of phospholipids but did not affect their content. In chronic hyperphenylalaninemia more distinct alterations in brain phospholipids metabolism were manifested as a decrease in their content and in their metabolic intensity. The data obtained suggest that brain demyelination developed in chronic hyperphenylalaninemia.
