title: [Changes in the structure and metabolism of rat thymus nucleic acids following cessation of long-term administration of different doses of tritium oxide].
abstract: A study was made of the processes of restoration of metabolism and nucleic acid indices in rat thymus after the cessation of the long-term administration of various doses of tritium oxide. The restoration of the indices under study was only observed after tritium dose of 0.37 MBq(g.day)-1. At higher doses, 0.925 and 1.85 MBq(g.day)-1 the recovery was transient and the indices changed again.
