[Humoral mechanisms of regulating reparative osteogenesis]. / O gumoral'nykh mekhanizmakh reguliatsii reparativnogo osteogeneza.

The effect of the blood serum of animals with active osteogenesis on the biosynthesis of nucleic acids, protein, and on the mineralization of the regenerating bone tissue was studied in experiments in vivo and in vitro. Incorporation of DNA and protein labeled precursors (3H-thymidine and 14 C-proline, respectively) was increased and the mineralization of the bone callus (85Sr incorporation) was accelerated in the recipients. Comparison of nucleic acids and protein biosynthesis stimulation sequency allows to suppose that the active serum principle promotes the increased cell proliferation in the fracture area.
