[Oxidation and phosphorylation in rat liver nuclei and nuclear membranes in postnatal development and regeneration after partial hepatectomy]. / Okislenie i fosforilirovanie v iadrakh i iadernykh obolochkakh kletok pecheni krysy v protsesse postnatal'nogo razvitiia i regeneratsii posle chastichnoi gepatektomii.

Specific oxygen consumption by isolated nuclei of liver cells of newborn rats is higher and phosphorylation is lower as compared to adult animals. This is correlated with a higher free cytochrome oxidase activity as determined in the absence of detergents or tetramethyl-p-phenylenediamine. Correspondingly, oxygen consumption by isolated nuclear membranes of rat liver 44 hrs after partial hepatectomy is also increased and the P/O ratio is decreased 2.2-fold as compared to the controls.
