[Effect of a single administration of hydrocortisone within various periods of a day on the incorporation of the labeled precursor into nuclear proteins of intact rat liver].

A single administration of hydrocortisone within various periods of a day led to distinct and dissimilar alterations in distribution of 14C-lysine in erythrocytes, blood plasma and in liver tissue homogenates. The hydrocortisone injection also changed the synthesis of nuclear proteins, especially during the day time. The ability of cell-targets to accept the hormonal signal depended on the functional state of cell chromatin, which is responsible for realization of the signal effect.
