[Aspartate-carbamoyltransferase activity of rabbit liver tissue following x-irradiation and vitamin and ATP administration].

Under the effect of total X-ray irradiation (450 R) the changes in activity of aspartate-carbamoyltransferase in the rabbit liver are of wavy character depending on the time passed after irradiation. Administration of vitamin B (with ATP, in combination with ATP and B1 as well as with FMN and PP) is shown to produce an activating effect on the enzyme function in the irradiated animals.
