[The pineal gland's peptides factors and the rhythms of functions of the thymus and bone marrow in animals during aging].

It was investigated the influence of pineal peptides on the aging changes both circadian rhythm of thymic serum factor (FTS) titer in male rats Wistar and circannual rhythms of FTS, the amount of stromal cells-precurcors (CFC-F), granulocyte-macrophage cells-precurcors (CFC-GM), CD4+, Mac-1+ and CD19+-cells in bone marrow of male mice CBA. Epithalamin was injected chronically beginning from 6 month in rats and 4 month in mice. In old animals the rhythmical disturbancers of the indices characterized by loss of fluctuations, displacement of seasonal acrophase, increased or diminished amplitude, inversion of rhythm and desynchronization.
