title: [Tumor progression as a factor of variability of diurnal rhythm of phosphorus metabolism in a tumor].
abstract: In a transplanted lymphosarcoma of rats by means of Cosinor method we discovered rhythm of P32 inclusions with ultradian and circadian periods. In the course of tumor growth changes of spectrum of periods, amplitudes and acrophases of rhythms take place. These shifts are explained by the progression and clonal structure of neoplasms.
